Outfall

With outfall is in hydrology any kind of channel flow, for example, water and land drainage, refers to, in which water in the form of sewage, storm water or drainage water can drain water into a ( larger ). Natural outfall are open watercourse, the water from other ( smaller ) waters absorb and derived from bodies or drainage systems.

Use and wastewater treatment,

The discharge of wastewater is one of the possible uses of a receiving water.

For the initiation of a water license issued by the competent authority (such as the Water Authority ) must be applied for in the rule. The authorization may be granted in the form of a permit. Obtaining a higher-quality water rights permit is in accordance with § 14 Section 1 No. 3 Water Act (CWA ) is not possible.

Reduction of peak levels by receiving water

It is sometimes argued that larger receiving water can be used to flooding, such as the Elbe flood in 2002, to take the edge off. Here, the success depends significantly on the time at which the receiving water is flooded and the charging stand which he had before. Some experts doubt a more than marginal effectiveness of these top level regulation.

Basically this system to improve the performance of the water system or the improvement of the high water retention would be suitable. Entlastungsgerinne, flood channels allow the capping of flood peaks by increasing the discharge capacity of the main channel through the creation of additional flume for the partial derivative of the flood wave. Polder or other retention areas can be targeted more or less flooded. This creates a retention ( a support ) of a portion of the flood wave with the target, the peak of the flood to cut. The discharge takes place this retention areas, if sufficient capacity is again given in the river network.
