Absorbent wells

By

Wells filled with infiltration material and covered with soil, stones or other covering that absorb water from nearby paved surfaces

Dry detention reservoirs and depressions of any capacity

By

Natural or artificially created detention basins and depressions with a specific retention capacity can be used as temporary water reservoir for runoff water during heavy rainfall. They slow down the surface runoff; thus they contribute to a delay and attenuation of flood waves. They should be located at the deepest point in almost any surrounding…

Linear protection measures

By

Linear protection measures help to direct the water to areas, where it does not cause harm. Such measures are flood protection dams, flood protection walls, mobile flood protection systems, water drains (enhancement, removal of obstacles), storm water drainage and culverts, emergency waterways, flood channels, road drainage in case of new constructions and refurbishment. They have…

Assessing and clearing of environmental flood damages

By

The measure includes the assessment of damages to the environment, mostly caused by accidents at sources of pollution e.g. containers with hazardous materials. Procedures and criteria’s need to be defined (beforehand).

Dry retention reservoirs with a constant flow

By

Various types of retention basins through which a watercourse flows. There is always a barrier across the course of the watercourse, and during low water the watercourse runs unhindered through the bottom outlet. As soon as more water flows than the standard discharge of the bottom outlet allows, this increased discharge is held back and…
