Modelling the Hydrological Response of Extreme Floods in Sweden
Hydrological Response Extreme Floods Sweden
2009/10/26
Hydrological models are today used for simulating extreme floods with the purpose of designing dams and spillways. In doing so, an extrapolation beyond the floods of the calibration period is made. Th...
The Effect of Climate Change on Floods in British Columbia
Effect of Climate Change Floods British Columbia
2009/10/23
A hydrological modelling of the flood response of two watersheds to climate
change are presented. The two study watersheds are the Upper Campbell and the
Illecillewaet watersheds located in British ...
Design Values for Precipitation and Floods from M5 Values
Design Values Precipitation and Floods M5 Values
2009/10/23
The M5 method, originally proposed by the Natural Resource Council in UK, is used for estimating precipitation in Iceland. In this method the M5 (24-hour precipitation with 5-year return period) is us...
Characteristics of the extreme rainfall event and consequent flash floods in W Slovenia in September 2007
extreme rainfall event consequent flash floods W Slovenia
2009/12/16
During a weather front that passed over large parts of Slovenia on 18.9.2007, extreme rainfall events were triggered causing several severe flash floods with six casualties. Out of 210 municipalities ...
Detecting the influence of land use changes on discharges and floods in the Meuse River Basin – the predictive power of a ninety-year rainfall-runoff relation?
Meuse River Basin rainfall-runoff
2009/5/15
Quantifying how changes in land use affect the hydrological response at the river basin scale is a current challenge in hydrological science. A daily discharge record (1911–2000) of the river Meuse (2...
The dynamics of cultivation and floods in arable lands of Central Argentina
arable lands floods Central Argentina
2009/4/28
Although floods in watersheds have been associated with land-use change since ancient times, the dynamics of flooding is still incompletely understood. In this paper we explored the relations between ...
Influence of the Yesa reservoir on floods of the Aragón River, central Spanish Pyrenees
reservoir flood control flood seasonality flood frequency river regime Pyrenees
2009/3/17
The Yesa reservoir, the largest Pyrenean reservoir, was constructed in 1959 to supply water to new irrigated areas in the Ebro Depression, NE Spain. It is filled from October to May-June and then rele...
Effects on floods of recent afforestation and urbanisation in the Mella River (Italian Alps)
floods land use changes afforestation urbanisation
2009/3/17
River floods are influenced by factors such as the duration, intensity and spacial distribution of precipitation and the land-use as well as the morphological characteristics of the river basin. While...
Modelling floods in the Ammer catchment: limitations and challenges with a coupled meteo-hydrological model approach
RAPHAEL modelling forecasting model coupling
2009/3/12
Numerous applications of hydrological models have shown their capability to simulate hydrological processes with a reasonable degree of certainty. For flood modelling, the quality of precipitation dat...
Hydrological and meteorological aspects of floods in the Alps: an overview
floods mountain hydrology meteorological models
2009/3/12
This introductory paper presents and summarises recent research on meteorological and hydrological aspects of floods in the Alps.
The contribution of soil structural degradation to catchment flooding: a preliminary investigation of the 2000 floods in England and Wales
soil structure land management Curve Number
2009/3/12
During the autumn of 2000, England and Wales experienced the wettest conditions for over 270 years, causing significant flooding.
Use of several indices of event severity for floods and droughts
drought severity index composite index event severity
2009/3/12
An examination is made of the true return periods associated with certain types of composite indices for the rareness of events. In particular, return periods are evaluated separately for several diff...
Flood Risk Growth under Global Change– Yangtze Floods in Perspective
Global Change Yangtze River Flood risk
2008/12/2
Recent floods have become more abundant and more destructive than ever in many re-gions of the globe. Catastrophic floods observed since 1990 all over the world have led to record-high material damage...
Flash-floods in Catalonia:the social perception in a context of changing vulnerability
Flash-floods Catalonia social perception changing vulnerability
2010/1/28
In assessing a flood event two risk components need to be considered: the intrinsic hazard of the hydrometeorological event causing the flood and the vulnerability of the area where the precipitation ...
Peak and volume of river flows are functions of the catchment surface characteristics. This means that any impacts to the run-off regime (for example surface sealing and river training) could affect p...
