THE ROLE OF TERRAIN CHARACTERISTICS IN FLOOD MANAGEMENT, ATTICA, GREECE
TERRAIN CHARACTERISTICS ATTICA FLOOD MANAGEMENT
2009/10/13
The purpose of this study is to investigate the role of terrain characteristics in flood management studies in Attica, Greece. Special emphasis is given to the peak storm runoff of the drainage basins...
FLOOD ZONING USING THE HEC-RAS HYDRAULIC MODEL IN A GIS ENVIRONMENT
Soil Conservation Service flood zone perennial Laeen Soo River
2009/10/12
This research estimates the flood zone and economic damages over an 8.2 km reach of the perennial Laeen Soo River in the northern Khorasan Province, Iran, using HEC-GEORAS, a combination of HEC-RAS wi...
RETURN PERIOD ANALYSIS AS A TOOL FOR URBAN FLOOD PREDICTION IN THE NIGER DELTA: A CASE STUDY OF PORT HARCOURT CITY, NIGERIA
return period analysis urban areas flood prediction
2009/10/12
The study examined return period analysis as a tool for flood prediction in urban areas. This technique enables us to know when an event is expected to occur, be equaled, or be exceeded. When floods o...
A look at the links between drainage density and flood statistics
drainage density flood statistics
2009/7/22
We investigate the links between the drainage density of a river basin and selected flood statistics, namely, mean, standard deviation, coefficient of variation and coefficient of skewness of annual...
How crucial is it to account for the antecedent moisture conditions in flood forecasting? Comparison of event-based and continuous approaches on 178 catchments
soil moisture accounting flood forecasting moisture conditions
2009/7/22
This paper compares event-based and continuous hydrological modelling approaches for real-time forecasting of river flows. Both approaches are compared using a lumped hydrologic model (whose structure...
On the role of the runoff coefficient in the mapping of rainfall to flood return periods
runoff coefficient rainfall flood return periods
2009/7/22
While the correspondence of rainfall return period TP and flood return period TQ is at the heart of the design storm procedure, their relationship is still poorly understood. The purpose of this pape...
Improved estimation of flood parameters by combining space based SAR data with very high resolution digital elevation data
synthetic aperture radar devastating catastrophes flood parameters
2009/7/22
Severe flood events turned out to be the most devastating catastrophes for Europe's population, economy and environment during the past decades. The total loss caused by the August 2002 flood is estim...
A grid-based distributed flood forecasting model for use with weather radar data：Part 2. Case studies
flood forecasting model rainfall-runoff model weather radar data
2009/6/5
A simple distributed rainfall-runoff model, configured on a square grid to make best use of weather radar data, was developed in Part 1 (Bell and Moore, 1998). The simple form of the basic model, ref...
Incorporating river morphological changes to flood risk assessment:uncertainties, methodology and application
Iriver morphological changes flood risk assessment uncertainties methodology application
2009/12/16
Risk zonation maps are mostly derived from design floods which propagate through the study area. The respective delineation of inundated flood plains is a fundamental input for the flood risk assessme...
Operational hydro-meteorological warning and real-time flood forecasting：the Piemonte Region case study
hydro-meteorological warning flood forecasting
2009/5/18
The development and implementation of a real-time flood forecasting system in the context of the Piemonte Region's hydro-meteorological operational alert procedure is described. The area of interest i...
National flood modelling for insurance purposes：using IFSAR for flood risk estimation in Europe
digital terrain models Flood risk flood events
2009/5/18
Flood risk poses a major problem for insurers and governments who ultimately pay the financial costs of losses resulting from flood events. Insurers therefore face the problem of how to assess their ...
An empirical method for estimating future flood risks for flood warnings
flood risks flood warnings
2009/5/18
Since medium and long-term precipitation forecasts are still not reliable enough, rough estimates of the degree of the extremity of forthcoming flood events that might occur in the course of dangerou...
Utility of different data types for calibrating flood inundation models within a GLUE framework
Generalised Likelihood Uncertainty Estimation GLUE framework flood inundation
2009/5/18
To translate a point hydrograph forecast into products for use by environmental agencies and civil protection authorities, a hydraulic model is necessary. Typical one- and two-dimensional hydraulic mo...
Cascading model uncertainty from medium range weather forecasts (10 days) through a rainfall-runoff model to flood inundation predictions within the European Flood Forecasting System (EFFS)
Generalised Likelihood Uncertainty Estimation weather forecasts uropean Flood Forecasting System
2009/5/18
The political pressure on the scientific community to provide medium to long term flood forecasts has increased in the light of recent flooding events in Europe. Such demands can be met by a system co...
