The measure covers all kinds of inormal planning documents for the improvement of land management in order to counteract dangerous phenomena of soil erosion and surface runoff in risk areas or minimise their effects (e.g. natural retention programs, urban adaptation plans for climate change, etc.). All regulations aim at determining directions of proceedings to reduce…
Pathways of concentrated surface runoff should be stabilised by permanent greening to prevent erosion. They can be reinforced by stones so that they are able to transfer the concentrated surface runoff without the occurrence of erosion on the pathway. The most common shape is a parabola with a low depth, which is most similar to…
Soakaways are buried chambers that store surface water and allow it to soak into the ground. They are typically square or circular excavations either filled with rubble or lined with brickwork, pre-cast concrete or polyethylene rings/perforated storage structures surrounded by granular backfill. They can be built in many shapes and can often be accommodated within…
Reservoirs can be classified, among other criteria, according to size, however, the classification varies from country to country (e.g. CZ <2 000 000 m³ in parts smaller than 100 000 m³). For heavy rainfall risk management, small reservoirs on smaller water courses are of particular importance. They can protect objects in risk areas from the…
Such dikes aim to shorten the length of slope, thus slowing down surface runoff and reducing soil erosion on arable land. They also support the infiltration into the soil. They need to be can be constructed in the direction of contours with a zero longitudinal slope. Both, the area in front of the barrier and…
Furrow diking (also called tied ridging or furrow damming) is the formation of small earthen dikes across furrows e.g. for potato farming. A similar technique is soil pitting – the formation of small depressions at closely spaced intervals. Such techniques hold rainwater in place until it infiltrates the soil.
