Land-use planning is an effective instrument to reduce future heavy rain risk. The heavy rain risk can decrease significantly, if changes of use, adjustments of use, restrictions of use or heavy rain-adapted construction and development in flood prone areas are considered in both phases of planning: formulation and implementation of plans. The power of the…
All pluvial flood events with damages should be documented and analysed regarding causes and impacts. The measure includes the assessment of buildings and infrastructure concerning their usability (e.g. transport routes, water supply, waste water disposal). Collected data are the basis for compensation requests to insurance or public disaster funds (if available). Moreover, lessons learnt can…
Organisational precautions as well as emergency measures are taken immediately after an event in order to guarantee the functionality of structures that aim at the protection against pluvial flooding (e.g. removal of debris and mud).
Design of forest roads should be done in a way that surface water is diverted to the forest aside. Various surfaces cross drain solutions with a different level of maintenance need are available (e.g. rolling drain dip, culverts, rubber strips). They need to be combined with ditch dams for directing runoff. New forest roads should…
The measures reside in terrain modifications of channels and floodplain to increase their ability to slow down the runoff and to create inundation zones so that potential consequences of surface runoff would be reduced. They can include individual modifications that are generally termed “restoration”. Specifically, modification of the channel’s course, branching of streams, channel stabilisation,…
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).
