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…
This measure resides in maintaining good forest health conditions through appropriate management (e.g. development of stable, stepped, unequal-aged forests, uniform shelter-wood systems and partial systems, coppice forests). The aim is to increase the soil infiltration, slowing surface runoff and reduce the risk of soil erosion by improving the forest health conditions. The management in forests…
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).
Larger open spaces, caused for example by timber harvesting and storms, are particularly critical areas for the development of floods. Avoiding large open areas – e.g. by promoting shelter before timber harvesting – and closing the resulting open areas as quickly as possible can noticeably reduce runoff from flood-sensitive catchment areas.
The measure includes the assessment of damages at buildings and infrastructure (e.g. transport routes, water supply, and waste water disposal) concerning their usability and the necessity for restoration after an event. The measure is also important for the settlement of claims through insurance companies. In case that support from public disaster funds is available, procedures…
