|Floods have become one of the most frequent occurring natural disasters. It causes huge loses to economy of a country by damaging assets, infrastructures, crops, live stocks, etc. A large number of populations are affected by floods almost every year. Future climatic scenarios have projected an increase in frequency and intensity of rainfall globally. Therefore, flood events are expected to increase further due to increasing trend of high intensity rainfall i.e. floods with higher frequency and magnitude are expected in future.|
Flood forecasting is considered one of the efficient ways for mitigation flood risks. Flood forecasting models helps in predicting the flood in advance with adequate lead time so that the concerned officials and authorities gets sufficient time for effective planning and evacuation of people from area, which are likely to be inundated. Broadly, operation of a flood forecasting model includes 3 components: (i) Data collection and transmission, (ii) Hydrological and Hydraulic modelling, and (iii) Dissemination of Information to the User. There is need to understand and improve each component for accurate flood forecasting for the area of interest.
