surat is a highly developed, thickly populated cosmopolitan character city with full of various activities going on day and night. any natural calamity which causes loss of lives to property and infrastructure along with effects on industrial processes going on has serious impact on economy of the state. therefore, it becomes highly necessary that flood events are studied and analyzed properly ...
There is a wide variety of flood damage models in use internationally, differing substantially in their approaches and economic estimates. Since these models are being used more and more as a basis for investment and planning decisions on an increasingly large scale, there is a need to reduce the uncertainties involved and develop a harmonised European approach, in particular with respect to th...
Estimation of floods in a basin with various return periods is one of the effective management strategies for reducing flood damage. One of the methods for estimating flood discharge is to make synthetic unit hydrograph using the physical characteristics of the basin. The more accurate inputs of the model, the more validated results. Hence, in basins in which Instantaneous peak discharge is rec...
The South African Weather Service is mandated to issue warnings of hazardous weather events, including those related to heavy precipitation, in order to safeguard life and property. Flooding and flash flood events are common in South Africa. Frequent updates and real-time availability of precipitation data are crucial to support hydrometeorological warning services. Satellite rainfall estimatio...
In the wake of increasing flood disasters, there is an increasing use of flood inundation models to assess risks and impacts at different temporal and spatial scales. Assessing the impacts of extreme climatic rainfall events will require developing design rainfall profiles to represent rainfall under different conditions. Rainfall profiles of different return periods were developed using the Fl...
Background and objective: Floods are among the most dangerous natural disasters that causes loss of life and property every year. The destructive effects of floods are more documentedو due to climate change and increasing economic and social development. Social and infrastructural vulnerabilities have also increased due to human settlement adjacent to river floodplains. Therefore, to prevent mo...
Flood risk can be reduced by means of flood forecasting, warning and response systems (FFWRS). These systems include a forecasting subsystem which is imperfect, meaning that inherent uncertainties in hydrological forecasts may result in false alarms and missed events. This forecasting uncertainty decreases the potential reduction of flood risk, but is seldom accounted for in estimates of the be...
