Rules of Spatial Planning Rules of Spatial Planning
in Flood Managementin Flood Management flood reduction is part of sustainable development and the various action possibilities
to improve preventive flood protection based on spatial planning and urban development can be described as follow
bull Protection of existing retention areas eg declaration of flood areas etcbull Extension of retention areas eg creating detention ponds etcbull Retention in the catchments eg restoration of small streams etcbull Minimisation of damage potential eg preventive land-use management etcbull Technical flood protection measures eg dikes retention ponds etc
As shown from above flood risk can only effectively be reduced if in addition to the technical measures spatial planning regulates land-use in flood-prone areas

bull Dynamic Metahuristics Algorithms (DMA) potentially have these capabilities to produce set of high quality real-time designs that can model more closely and easily the objective functions and tolerate the noisy evaluations given by these functions
bull The final design should be robust (ie performs well over a wide range of environment conditions) and flexible (ie allows easy adaptation after the environment has changed)
Disaster Warning Network (DWN)Disaster Warning Network (DWN)
bull DMAs can successfully handle a mix of continuous and discrete parameters as well as selecting individual components from database Therefore another objective of this project is to connect DWN to a database which includes all the related information (physical geographicaland biochemical) colleted by other observation techniques (eg Geographic Information System (GIS) Remote Sensing (RS) photogrametery internet air (water and soil) survey technology etc)
Disaster Warning Network (DWN)Disaster Warning Network (DWN)
DWN can effectively optimise this problem by 1) providing access to a wide range of data types in real-time 2) combining the observational data with innovative data analysis to improve forecasting and risk assessment 3) and being a user friendly tool in decision support of environmental management

in Flood Managementin Flood Management flood reduction is part of sustainable development and the various action possibilities
to improve preventive flood protection based on spatial planning and urban development can be described as follow
bull Protection of existing retention areas eg declaration of flood areas etcbull Extension of retention areas eg creating detention ponds etcbull Retention in the catchments eg restoration of small streams etcbull Minimisation of damage potential eg preventive land-use management etcbull Technical flood protection measures eg dikes retention ponds etc
As shown from above flood risk can only effectively be reduced if in addition to the technical measures spatial planning regulates land-use in flood-prone areas

Disaster Warning Network (DWN)Disaster Warning Network (DWN)
bull DMAs can successfully handle a mix of continuous and discrete parameters as well as selecting individual components from database Therefore another objective of this project is to connect DWN to a database which includes all the related information (physical geographicaland biochemical) colleted by other observation techniques (eg Geographic Information System (GIS) Remote Sensing (RS) photogrametery internet air (water and soil) survey technology etc)
Disaster Warning Network (DWN)Disaster Warning Network (DWN)
DWN can effectively optimise this problem by 1) providing access to a wide range of data types in real-time 2) combining the observational data with innovative data analysis to improve forecasting and risk assessment 3) and being a user friendly tool in decision support of environmental management

Rules of Spatial Planning Rules of Spatial Planning
in Flood Managementin Flood Management flood reduction is part of sustainable development and the various action possibilities
to improve preventive flood protection based on spatial planning and urban development can be described as follow
bull Protection of existing retention areas eg declaration of flood areas etcbull Extension of retention areas eg creating detention ponds etcbull Retention in the catchments eg restoration of small streams etcbull Minimisation of damage potential eg preventive land-use management etcbull Technical flood protection measures eg dikes retention ponds etc
As shown from above flood risk can only effectively be reduced if in addition to the technical measures spatial planning regulates land-use in flood-prone areas

in Flood Managementin Flood Management flood reduction is part of sustainable development and the various action possibilities
to improve preventive flood protection based on spatial planning and urban development can be described as follow
bull Protection of existing retention areas eg declaration of flood areas etcbull Extension of retention areas eg creating detention ponds etcbull Retention in the catchments eg restoration of small streams etcbull Minimisation of damage potential eg preventive land-use management etcbull Technical flood protection measures eg dikes retention ponds etc
As shown from above flood risk can only effectively be reduced if in addition to the technical measures spatial planning regulates land-use in flood-prone areas

bull The final design should be robust (ie performs well over a wide range of environment conditions) and flexible (ie allows easy adaptation after the environment has changed)
Disaster Warning Network (DWN)Disaster Warning Network (DWN)
bull DMAs can successfully handle a mix of continuous and discrete parameters as well as selecting individual components from database Therefore another objective of this project is to connect DWN to a database which includes all the related information (physical geographicaland biochemical) colleted by other observation techniques (eg Geographic Information System (GIS) Remote Sensing (RS) photogrametery internet air (water and soil) survey technology etc)

Disaster Warning Network for Danube Disaster Warning Network for Danube Basin (DWN)Basin (DWN)
bull DWN is a system of satellites and ground stations for providing real time early warning of the impact of a disaster
bull DWN implements a network of Control Stations (CSs) spread over the whole geographic area of the hazard and transmits their observations to a master station
bull DWN provides this reliable information on a continuous basis through the parallel process of coverage accuracy prediction and integrity risk simulation functions
