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…
All relevant actors in a community should be involved for developing an awareness of the risk and for starting cooperation. This can be done e.g. by establishment of a coordination circle (“round table”) with the participation of all actors from affected municipal departments, community council, citizens, emergency services, etc. An audit for recording the strengths…
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…
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…
Land consolidation is a planning process likely to clarify land ownership, reduce fragmentation of agricultural land ownership and to improve rural infrastructure and living conditions. This way it can reintroduce technical measures into collectivized field blocks, and positively influence landscape fragmentation for improving water retention and avoiding uncontrolled hazardous surface runoff. Land consolidation processes should…
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…
