What is a drainage area?
The drainage area is a part of the soil above which water from rain and melting snow runoffs into a single water body. This water body can be a swamp, a drainage pond, a lake, a river or an inflow. The drainage area of the area is very important because it determines the wastewater management strategy and can help determine the source of pollutants. In many cases, in order to prevent pollutants in natural areas, development is necessary to build some kind of basin to stop the water. This basin is often referred to as a drainage pond. Some of them are simply fenced and left unattended, while others are used as peaks for parks or other recreational areas. For example, looking at a particular drainage area can help determine where it is advisable to build buildings and roads and which areas should be avoided. Maps showing drainage areas are often available from local governments or from national organizations such as American geological survey.
change the drainage area or diverting water from one is often very difficult because so much of it depends on the natural relief from the area. The physical division between areas is often very impressive and creates significant obstacles. That is why areas that are susceptible to floods tend to remain prone to floods and areas that are without floods often remain. Although it may seem as simple as diverting water to another area, it would take a lot of money and time to do it.
If a pollutant is found, the problem can often be traced back to the source by those who understand what the drainage area is. Rarely does the problem initially begins where it is found. Scientists and environmental workers may therefore trace the problem back to the source by looking at the maps and reading in the field as they go.
To prevent this situation to become a problem, someThe drainage areas have buffers and wetlands that serve as a filter before water runs into tributaries. Some of them are natural and some of them are designed by man for the specific purpose of protection of other natural areas. In some cases, wetlands were exhausted because the accumulation of organic material made them the main areas for agriculture. Some of them are now renewed through public or public/private partnerships.
