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…
Traditional surface water drainage systems are often overloaded in case of heavy rain and thus cause flooding and damages. They can be developed further to “sustainable urban drainage systems” aiming on increasing their capacity e.g. when it comes to heavy rainfall and aligning them with natural water processes. There is a large collection of structural…
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).
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…
Walls using in its construction vegetation fed with atmospheric precipitation. During rainfall, some rainwater is used to wet the surface of the plants and their life needs, while the part returned to the atmosphere in the form of evapotranspiration.
Terracing is an ancient technology allowing the farming and building on steep and indented terrain. Farmland terraces consist of terrace platforms and terrace slopes or walls. In rural settings, the measure can reduce erosion and surface runoff by slowing rainwater to a non-erosive velocity. The measure is recommended for farmland with slopes >15°. However, terraces…
