Hydrology Tutorial on Flood

 Floods refer to the overflow of water onto normally dry land, often caused by heavy rainfall, melting snow, or dam failure. They can cause significant damage to infrastructure, agriculture, and human settlements. Studying floods is crucial as it helps us understand their causes, patterns, and impacts on both the natural environment and human societies. This knowledge enables us to develop effective strategies for flood prevention, mitigation, and response, ultimately saving lives and minimizing economic losses. Click here to see the tutorial.

Five empirical models, for prediction of peak discharge and estimation of flood

"A flood is an overflow of water on normally dry ground". This is most commonly due to an overflowing river, a dam break, snow-melt, or heavy rainfall. Tsunamis, storm surge, or coastal flooding are some of the examples of common flooding whereas instances of extreme flooding includes the flood  in 1931 at China which killed between 2,000,000 and 4,000,000 people.In 2002, Texas flood which was caused by a reservoir overflow. In just three days, the floodwaters carved canyons measuring 1.4 mile (2.2 kilometres) long and  20-foot-(6 meters)-deep. Floods can be measured for height, peak discharge, area inundated, and volume of flow. Due to the ability of this extreme event to cause disasters, it is important to predict the event well in advance or at the time of designing flood control structures.Flood is a result of a discharge;generally peak discharge;which the drainage network can not hold and eventually overflows and causes inundation.  There are various methods to estimate
