Land use and land cover changes as well as intensification or extensification of land use are altering the hydrologic system and have potentially large impacts on flooding in lower lying areas. Upstream and downstream interconnections, interactions and action’s intereffects should be taken into consideration in planning activities, especially when problems occur in settlement areas. Formal…
Field subdivision aims to grow various, alternating arranged crops in a strip-type pattern, preferably in combination with cultivation across the slope. It is suitable esp. for crops with a tendency for erosion like corn or sugar beet that alternate with strips of e.g. gras or uncultivated fields. Crops prone to surface water runoff, erosion and…
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…
This measure helps to significantly reduce the risk of erosion on farmland. Due to the roughness of the surface structure, it helps the surface water to pass into the subsoil. In addition, surface water runoff is significantly decreased by a number of temporary storage spaces and a high level of turbulence. However, the measure is…
Furrows are shallow and wide ditches on arable land with mild slopes and a small longitudinal gradient. They allow interception, infiltration and alternatively drainage of surface runoff. They should be dimensioned properly for meeting functional requirements and require maintenance.
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…
