Student Projects/Flood its types and causes


Disaster is a natural or human that caused phenomenon/ caused wonder, which causes genuine disturbance of the working of a network or a general public causing broad human, material, monetary and ecological misfortunes which inspired the capacity of the influenced community, society to adapt utilizing its assets. Floods are a typical component in the nation that happens year in numerous parts mostly south India.


“Flood is a state of high water level along a river channel or on the coast that leads to inundation of land, which is not usually submerged”- The Center for Research on the Epidemiology of Disasters (CRED).

Flooding may result from the volume of water inside a course, for example, a stream or lake, which floods or breaks levees, with the outcome that a touch of the water makes tracks in a contrary heading from its run of quite far.

There are a few distinct sorts of floods. Most people group experience just a couple of them. Floods are commonly assembled into the accompanying sorts. Different types of floods, they are:

1) Flash flood

2) Coastal flood

3) River flood

4) Urban flood

1) Flash flood

These are realized by a significant storm or the sudden appearance of water over a brief time period. The name "streak" implies their brisk occasion (conventionally inside minutes to hours in the wake of overpowering precipitation event) and moreover to their irate downpours of water that move with exceptional speed.

2) Coastal flood

Coastal flooding is the inundation of land areas along the coast by seawater, Common causes of coastal flooding involve:

1. High tide.

2. Tsunamis.

3. Storm surge.

3) River flood

River flooding occurs when water levels in rivers, lakes, and streams rise and overflow onto the surroundings banks, shores, and neighboring land.

4) Urban flood

Urban flooding is the drenching of land or property in a manufactured circumstance, particularly in more thickly populated zones, achieved by precipitation overwhelming the breaking point of the waste system, for instance, storm sewers.

Causes of Flood


Substantial downpours with high force in a brief-term those outcomes floods. For different reasons if 30mm precipitation successively beyond what five days can likewise result in floods in low laying zones.

Overflow of River

The movement of course in the banks to cause flooding. This happens when there is more water upstream than foreseen and as it streams downstream to the circumscribing low-lying locales (additionally called a floodplain), there is an affected and water gets into the land.

Strong winds in the coastal risk areas

Seawater can be carried by massive winds and hurricanes onto dry coastal lands and cause flooding. Sometimes this is made worse if the winds carry rain themselves.

Dam breaking of the river

Burst dam or levee, Embankment, known as levees, are worked at the edge of a conduit and are used to shield high water from flooding encompassing the area. Overabundance water can similarly be intentionally released from the dam to shield it from breaking and that can in like manner cause flood.

Ice and snow-melts of many areas

In numerous chilly areas, substantial snow over the winter, for the most part, remains unmelted for quite a while. Some of the time the ice abruptly liquefies when the temperature rises, bringing about monstrous development of water into places that are generally dry. This is typically called snowmelt called a snowmelt flood.
