DEVELOPMENT OF FLOOD FORECASTING SYSTEM FOR DELHI CITY

Abstract

Floods annually affect a large population of Indian population during the monsoon months from June to September every year. Flooding leads to the disruption in the socio-economic conditions and causes enormous damage to infrastructure and agriculture.without proper mechanism to predict the future conditions, it becomes very difficult for the authorities and the rescue teams to help relocate people to safer place and prevent loss of life and property. Also frequent and severe floods may affect the hydraulic structures, roads and nearby building as well. It may become the need of the hour. for that accurate prediction of input data such as rainfall and potential evapotranspiration data is very much important. India has already worked over the ensemble prediction of rainfall data. The only challenge now lies in the ensemble prediction of streamflow data in different channels and at different gauge points. once this mechanism gets established, then it would be very easy for a person to design future hydraulic projects and may select the factor of safety in the design appropriately. This may help in saving the project cost to a very great extent. Also it will help engineers to design the master plan of a particular city but checking of the extent of spread of the future city near the river banks and may also help in clearing of illegal encroachments along the river beds which may become frequently flooded in the future.
