چکیده

The aim of this study is to investigate the flood management and mitigation measures in ungauged NATURA protected watersheds. examined watersheds are located one most European significant areas (Prespa Natural Park North Greece). SCS-CN model was applied perform hydrological modeling for extreme rainfalls 50, 100 1000 return periods. Extensive field research conducted record all hydrotechnical works area, evaluate their current condition measure respective hydraulic characteristics. results showed that danger area generally low. However, almost half could not discharge high medium probability (50 years) peak flows. main causes extremely dense riparian vegetation has been developed on banks thalweg riverbeds some cases inappropriate dimensioning technical works. intense development vegetation, increased roughness coefficient reduced dimensions capability works, while restrictions regulations may be limiting any logging trimming activities within streams, especially priority habitat types. Special Ecological Evaluation studies educating public about necessity control impact, provide a framework thorough discussion areas.

Prioritizing flood producing potential in ungauged watersheds using the AHP-VIKOR method (Case study: Haji-Bakhtiar Watershed, Ilam)

Extended abstract 1- Introduction Flood is one of the most complex and destructive natural phenomena that cause significant damage to agriculture, fisheries, housing, and infrastructure and significantly affects social and economic activities (Chang et al., 2008). The relationship between geomorphological and hydrological parameters makes it possible to predict floods in gauged basins and gen...

Private Flood Mitigation Measures in a Changing Risk Environment

In Europe, water management is moving from flood defence to a risk management approach, which takes both the probability and the potential consequences of flooding into account. It is expected that climate change and socio-economic development will lead to an increase in flood risk in the Rhine basin. To optimize spatial planning and flood management measures, studies are needed that quantify f...

Regionalization of SWAT Model Parameters for Use in Ungauged Watersheds

There has been a steady shift towards modeling and model-based approaches as primary methods of assessing watershed response to hydrologic inputs and land management, and of quantifying watershed-wide best management practice (BMP) effectiveness. Watershed models often require some degree of calibration and validation to achieve adequate watershed and therefore BMP representation. This is, howe...
