A Flood is an overflow of water that submerges land which is usually dry. Sometimes a river receives too much extra water, either from heavy rain or other natural disasters. When this happens, the water overflows from its normal path in the river bed and onto dry land. There are many types and ways floods can occur, including, due to Overflow Rivers, due to extreme coastal events, by natural or artificial ground saturation. However, floods are not always caused by heavy rainfall. They can result from other phenomena, particularly in coastal areas where inundation can be caused by a Flood associated with a tropical cyclone, a tsunami or a high tide coinciding with higher than normal river levels. The immediate impacts of flooding include loss of human life, damage to property, destruction of crops, loss of livestock, and deterioration of health conditions owing to water borne diseases.
Flood forecasting is the use of forecasted precipitation and stream flow data in rainfall-run off and stream flow routing models to forecast flow rates and water levels for periods from a few hours to days ahead, depending on the size of the watershed or river basin. Weather forecast can provide advance warming of a flood and seasonal forecasters can alert of a heightened chance of flooding in the coming months. I have conducted many studies on the forecasting methods of floods and invented the Global Monsoon Time Scale, Astroclimatic weather forecasting study time scales, bioforecast along with the G.R. Irlapati’s Geo-scope which may also useful in predicting the dam first Floods
