Ditches allow intercepting, infiltrating and alternatively draining the surface runoff without causing damage. They should be dimensioned to the corresponding return period of the discharge, meet functional requirements and get regular control and maintenance. Ditches on farmland are usually proposed in areas where the space for constructing furrows is limited. Within urban areas they are…
Effective and periodically updated emergency response plans for the case of flooding caused by heavy rainfall help civil protection units to get a quick overview on measures to be taken and also on their priorisation. They are an important part of disaster control planning and need to be set up by responsible institutions (e.g. in…
Small (unsealed) roads within forests and on farmland often cause surface runoff and erosion or they are damaged themselves in case of heavy rain. Furthermore, the road density can have a decisive influence on the water drainage of larger areas. Existing road network within forests and on farmland should be checked for its necessity and…
When flood occurs, safe drainage from the affected area is often dependent on the state of culverts and small bridges. These objects are often jammed by debris and thus cause local flooding. Often, the object itself is also damaged and as a result the traffic route is interrupted. Appropriate design in terms of capacity and…
The development of runoff routes can be prevented and retention can be improved on slightly sloping terrain by cultivating farmland across the slope along contours. Ideally, the soil should be farmed in a chequerboard pattern to control and slow down the flow of surface water. In principle, the avoidance of downhill lanes, the creation of…
Trans-border risk assessment, communication of hydrological forecasts, the harmonisation of technical standards; cross-border cooperation on emergency planning and consideration of the cross-border impact of projects exist for the management of fluvial floods. Cooperation can be improved for the management of heavy rain risk.
