Qu’est-ce que le dragage ?

Le dragage consiste à enlever les sédiments et les débris du fond des lacs, des rivières, des ports et d’autres plans d’eau. C’est une nécessité courante dans les cours d’eau du monde entier, car la sédimentation – le processus naturel de lavage du sable et de la vase en aval – remplit progressivement les canaux et les ports.

Le dragage est souvent axé sur le maintien ou l’augmentation de la profondeur des chenaux de navigation, des mouillages ou des zones d’accostage pour assurer le passage en toute sécurité des bateaux et des navires. Les navires ont besoin d’une certaine quantité d’eau pour flotter et ne pas toucher le fond. Cette profondeur d’eau continue à augmenter au fil du temps, à mesure que des navires de plus en plus grands sont déployés. Étant donné que des navires massifs transportent la majeure partie des marchandises importées dans le pays, le dragage joue un rôle vital dans l’économie nationale.

Le dragage est également effectué pour réduire l’exposition des poissons, de la faune et des personnes aux contaminants et pour empêcher la propagation des contaminants à d’autres zones du plan d’eau. Ce dragage environnemental est souvent nécessaire parce que les sédiments des villes et des zones industrielles et de leurs environs sont souvent contaminés par divers polluants. Ces polluants sont introduits dans les cours d’eau à partir de sources ponctuelles telles que les débordements d’égouts, les rejets municipaux et industriels et les déversements ; ou peuvent être introduits à partir de sources non ponctuelles telles que le ruissellement de surface et les dépôts atmosphériques. Le Bureau de l’intervention et de la restauration de la NOAA joue un rôle majeur dans la protection et la restauration des ressources naturelles marines lorsque des dommages environnementaux surviennent.

L’élimination des matériaux de dragage est gérée et réalisée par les gouvernements fédéraux, étatiques et locaux, ainsi que par des entités privées telles que les autorités portuaires. Le Corps of Engineers de l’armée américaine délivre des permis pour l’élimination des déblais de dragage ; l’Agence américaine de protection de l’environnement assure la surveillance et l’autorisation de l’élimination des déblais de dragage.

Dragage et gestion des déblais de dragage

Le dragage est l’enlèvement de matériaux au fond des lacs, rivières, ports et autres plans d’eau. La plupart des travaux de dragage sont effectués pour maintenir ou approfondir les chenaux de navigation, les mouillages ou les zones d’accostage afin de permettre le passage en toute sécurité des bateaux et des navires. Le dragage des zones contaminées peut également être effectué dans le but exprès de réduire l’exposition du biote marin et de l’homme aux contaminants et/ou d’empêcher la propagation des contaminants à d’autres zones de la masse d’eau. Ce type de dragage est appelé “dragage environnemental”. Le besoin croissant de chenaux plus larges et plus profonds et de méthodes de placement différentes a donné lieu au développement de nombreux types de dragues.
Le dragage est nécessaire en raison du processus naturel de sédimentation ; le sable et la vase qui s’écoulent en aval remplissent progressivement les chenaux et les ports. La sédimentation est un problème partout, des petites marinas à l’immense complexe portuaire de New York/New Jersey. Gérer les matériaux de dragage d’une manière écologiquement rationnelle n’est pas seulement responsable sur le plan environnemental – C’EST LA LOI. Avant que l’élimination des déblais de dragage ne soit autorisée, ceux-ci doivent satisfaire, entre autres choses, à un examen en trois parties conformément aux lois et règlements applicables.

Tout d’abord, il doit être démontré que le dragage est nécessaire.

Deuxièmement, il doit y avoir une analyse complète de toutes les méthodes raisonnables d’élimination des déblais de dragage et des lieux où ils seront éliminés.

Troisièmement, des tests doivent être effectués pour s’assurer que les matériaux à placer ne nuiront pas à l’environnement dans lequel ils sont placés. Un cadre technique pour ces évaluations est défini dans le document intitulé “Évaluation des effets environnementaux des solutions de remplacement pour l’élimination des déblais de dragage”.

La région 2 de l’EPA a formé l’équipe de gestion des déblais de dragage pour assurer la protection de la santé humaine et de l’environnement contre les effets néfastes potentiels qui peuvent être associés au dragage à New York, au New Jersey, à Porto Rico et dans les îles Vierges américaines. Pour plus d’informations sur les projets de dragage ailleurs aux États-Unis, veuillez vous référer à l’équipe nationale de dragage de l’EPA et au programme national de gestion des matériaux de dragage de l’EPA.

Le port de New York- New Jersey abrite le plus grand complexe portuaire de la côte est de l’Amérique du Nord. Le port de New York et la sortie du New Jersey de l’EPA traitent annuellement deux millions de conteneurs chargés, soit près de la moitié du total de l’Atlantique Nord (qui comprend les cargaisons en vrac, les automobiles et le pétrole, etc.) Cette activité crée environ 200 000 emplois liés ou dépendant du port et génère chaque année 30 milliards de dollars de recettes et 620 millions de dollars de taxes d’État et locales. La viabilité économique du port dépend de cycles réguliers de dragage pour maintenir les postes à quai ouverts et permettre une navigation sûre. L’EPA, en collaboration avec le Corps des ingénieurs de l’armée américaine, les États de New York et du New Jersey, les parties prenantes intéressées et le public, s’est efforcée de poursuivre le fonctionnement et le développement économique du port tout en préservant, conservant et restaurant les ressources naturelles du port.

Les sédiments dans et autour des villes et des zones industrielles sont souvent contaminés par divers polluants. Ces polluants sont introduits dans les cours d’eau à partir de sources ponctuelles telles que les débordements des égouts unitaires, les rejets et les déversements municipaux et industriels ou peuvent être introduits à partir de sources non ponctuelles telles que le ruissellement de surface et les dépôts atmosphériques.

L’élaboration de critères environnementaux ainsi que de lois et règlements nationaux aide l’EPA dans sa mission de protection et de préservation de l’environnement. L’élimination des matériaux de dragage dans l’océan ne peut avoir lieu que si un permis est délivré (en vertu de la loi sur la protection, la recherche et les sanctuaires marins) par le Corps des ingénieurs de l’armée américaine, en utilisant les critères environnementaux de l’EPA et sous réserve de l’accord de l’EPA. L’EPA est également chargée de désigner les sites d’immersion en mer recommandés pour l’utilisation de ces permis. Ces responsabilités sont assumées dans la région 2 par l’équipe de gestion des matériaux de dragage (DMMT).

En coopération avec le Corps des ingénieurs de l’armée américaine et les gouvernements des États et des collectivités locales, l’EPA doit évaluer les autres options d’élimination lorsqu’elle décide du placement correct des déblais de dragage. Ces options comprennent l’élimination en eau libre, dans les eaux intérieures, en montagne et en milieu confiné. L’USACE a effectué une évaluation de divers scénarios d’élimination. Veuillez vous référer au plan de gestion des déblais de dragage de l’USACE. Exit EPA disclaimer Grâce aux nouvelles technologies, telles que la décontamination, les déblais de dragage peuvent devenir un matériau productif qui peut être traité en conjonction avec des produits largement utilisés tels que les briques, le ciment et le verre.

What distinguishes free chat rooms

Compared with the liable to pay the costs offerers a free chats must make compromises, that is in view of the missing contribution incomes clearly obvious. Primarily the differences are thus within the service range: If you want to become acquainted with another single free of charge, then somewhat more expenditure lies before you – partner suggestions can expect you just as little as a personality test. However, if you browse through the large number of profiles, there are sometimes only limited filters available, which does not detract from the pleasant atmosphere, on the contrary. Experience has shown that young and communicative people who are primarily looking for a quick flirt, but who also have nothing against a deepening relationship, cavort on these pages.

Can free chat rooms be reputable?

This question can be answered clearly: Yes! However, you should consider that free chat sites are regularly used for trying out, i.e. for getting started. They find therefore many inexperienced members, who want to test this possibility of the establishment of contact for itself. This is actually no problem, because the handling of the dating portals is extremely simple. And yet you should be aware that a new contact may be a little hesitant to open up or even show skepticism – so be patient, which is appropriate for online dating anyway.

Can respectable dating sites be free of charge For the ladies it might be very pleasant that the gentlemen on these portals are in the majority – contrary to the liable to pay the costs offerers. The chance to be written to fast and by many other Usern is therefore very large. The average age of the users is regularly between 25 and 34 years. If this is too young for you, it is best to choose a free dating site for over 35-year-olds or seniors – they too can be found on the World Wide Web. Also with regard to the number of members, the free providers differ from the fee-based alternatives: The communities are significantly smaller, but still respectable. After all, it always depends on the one or the other.

So it’s up to you, the user, to be successful on free dating sites: On the one hand, you should not select the radius for your search too narrowly in order to increase your chances of a hit. You are sure to encounter nice and open-minded people – even with the pre-programmed addresses. Of course, more promising is an individual and personally formulated inquiry that explicitly addresses the respective profile and, above all, is of a high standard. Under no circumstances should you aim below the belt – you certainly don’t like that yourself any more than the other users. Present yourself authentically and make yourself interesting.

Making your own profile interesting

To visit a chat free of charge without registration and to hope for great success might not be very promising – at least if you are interested in serious contacts. The linchpin is a concise profile. Please pay attention to an attractive portrait photo, a creative motto that brings your personality to the point, correct and complete information.

Check yourself: If you are looking for a single, what are you looking for in the first place? The profile, of course – all the more important it is to take some time for it. After all, you determine nothing less than the first impression that other users can make of you. The photo alone decides whether your profile will be clicked on or not – so choose your photo carefully. You should present yourself in a humorous and relaxed way to directly arouse the interest of other members. Sometimes a selfie will also fit if it presents an important side of you. Using a free chat without a photo is not recommended if you are seriously looking for one.

Then there is the text field, which you can fill out freely: Apart from the fact that you should definitely stick to the truth, you should come up with an original description of yourself. Not too much, not too little – you can be quite mysterious. On the other hand, openness is recommended: communicate clearly who or what you are looking for. The ideas of the users go here far apart: If some are looking for a quick and noncommittal flirt, others for acquaintances for common leisure activities, there are also users who are looking for the great love. So spare yourself disappointments or annoying discussions by playing with open cards from the outset – you certainly expect the same from the other users of the free chat.

Contact possibilities at free chats

Even if the free providers have to keep their service slim, a nice selection of contact options is still open to you: Beyond the internal news system you can chat at many free chats and of course send gifts or emoticons. Furthermore, you are free to rate certain photos, postings or statements, for example with a Like. Show your sympathies and attract the attention of your dream partner, the prelude to an exciting flirt can be that easy.

You won’t even notice that there are neither standard greetings nor so-called icebreaker questions – anyway, the individual messages are much more meaningful and promising. So there are some differences to the payment pages, but they are hardly relevant in this point. A nice change is offered by the games, which make it easier to get to know each other at some free chats. Even if there are no apps and mobile flirting is not easy even with a responsive design, chats can act serious and appealing for free – you will find that out very quickly by yourself.

You will get in contact with other users quite quickly with your messages. With your own chat requests you can exchange information and details intensively, but patience is recommended here as well, so as not to frighten your counterpart. And yet the opportunity to make new friends in a very uncomplicated way, to deepen these friendships step by step and to get to know each other better – a nice alternative for shy and somewhat less determined people.

Use search filters skillfully and find dream partners

The established chats advertise with scientifically based methods of partner search. With the help of a personality test the suitable profiles are selected and presented in the Matching procedure – you cannot count on that with free chats. Here you have to become active yourself, partner suggestions are not submitted to you. The bottom line is that you will have to spend a little more time to select the candidates that come into question – but this also has its appeal: you can start your search with an open mind, regardless of any algorithms. However, it is important that you first think about what exactly you expect and are looking for.

As soon as you are clear about this, you can start: In the first step, take a look at the available search filters, with which you can already make initial selections. Use them as well as possible to limit the selection to a practicable level. In most cases, filters are provided that relate to appearance, height, figure or even hair color. Further criteria can be the concrete intentions, i.e. whether a user is only looking for a flirt or a serious relationship, but also certain habits such as alcohol or nicotine consumption. Even the age and region can be narrowed down to make the search successful. If a particular combination does not fit a profile, then change small nuances according to your preferences – you will quickly find out how to use the search filters optimally.

Free chats and the topic of security

There are always reports of rip-offs or fraud on online portals – and this also applies to online dating. Particularly annoying are the fake accounts that the providers have to defend themselves against: They try to encourage users to access paid services. A further phenomenon are the Romance Scammers. These are scammers that bring users into an emotional dependency, fake financial distress for them in order to get money. It is always amazing what ideas criminals come up with and how successful they are with them.

However, these approaches are now well known, so that chats can take targeted countermeasures. On the one hand, you will also find a button on the free providers that you can use to block users and report accounts that appear suspicious. Spam filters also ensure that certain messages, for example with advertisements for other chats, are sorted out. Of course, there are still gaps, even the payment pages can’t be sure to catch all fake accounts by checking their personal data. With the free chats, only limited effort can be made here, but none of the dating portals can guarantee a complete ID check. Remain therefore attentive, then nothing can happen.

Mobile flirting and dating apps – what’s behind them?

Mobile flirting with a dating appThe proportion of mobile users of dating platforms in Germany is still clear, but this trend will increase. It might be only a question of time, Europe-wide the relevant single Apps can already enjoy a large demand, as the user numbers of Tinder or LOVOO show. On its own App you will have to do without with the free chats however, but not on the possibility of accessing the side also on the way completely mobilely: Most Datingportals are programmed in such a way that they adapt themselves automatically to the respective equipment.

In contrast to the app, you therefore remain independent of the operating system, all important elements are thus reliably displayed – just like in the respective desktop version. However, please keep in mind that this consumes data volume and usually only a slimmed-down page is available. But if you want to stay in touch, react quickly to messages or start a chat, then you can look forward to the free chats.

Customer service and user-friendliness at free chats

One thing right from the start: The free chats are also easy to use and navigate, even if the layout is perhaps a little more economical or does not look quite modern. But that is certainly not what matters to you. Do not be bothered by the advertising, which is essential for the operators, all functions are intuitive and geared to the respective target group.

And yet, there are still some cutbacks to be made: Technical support or a hotline that promises help with flirting cannot guarantee a free dating site, nor can special events or seminars. These are rather offered by the big dating portals to increase your chances of a successful flirt. So it is up to you to arrange a very real meeting – in the various groups, forums or directly with another user. If the flirt sites are linked to the social media, however, the community organizes its own events – and that can be very exciting.

If there are any technical problems with the site, it’s best to send an email directly to the support – you won’t be successful over the phone. Even if it takes a while to process your request, it will usually be handled in a competent and friendly manner – the bottom line is that the service is also very good at the free chats.

Our conclusion: free chats that suit you

If you want to take your first steps towards online dating, then you can safely access free chats: you are sure to make new friends and meet nice people who you would not have met otherwise. However, it is doubtful whether the soul mates will work, this is where the platforms reach their limits. So just try out the dating platforms, but lower your expectations a little bit.

The numerous functions and, of course, the possibilities to exchange information directly or in groups are pleasant. The free chats do not have to hide in comparison to the cost-intensive alternatives, as they offer access to other singles, but also to exciting games that make flirting even more entertaining. The fact is, however, that the number of fake accounts is naturally higher here because the enormous amount of control required cannot be managed. So there is always a little caution, then you should master this hurdle. So if you get involved, you will definitely encounter a strong sense of community in the groups and interesting profiles – what you make of it is of course entirely up to you.
