Where does flood occur frequently?

Water barriers

Usually, the normal practice of water is that it leads from the top ground to below ground. This means if there is a higher ground adjoining a lower ground, the lower ground is more likely to experience floods.

Anywhere that rains occur, floods can easily develop. This is so as anytime there are heavy rains bring in more water than it can be absorbed by the soil, there is a heavy flood potential.

In numerous cities, there are buildings situated in waterways. Other places have terrible and blocked drainage systems.

The risk is that, with the excessive rains, water will invent its own level however it cannot locate its way then this lead to flooding.

Any plain low ground zone next to a lake, lagoon or river is too more prone to have floods as the water level goes up. This included shorelines and coastal areas, as seawater easily swept inland through strong tides, winds, and tsunamis.

What are natural or human-made causes for the flood?


Natural causes of a flood:

1. Rains

Each time there are heavy rains than the drainage system can take, there can be more chances of floods. Sometimes heavy rain results in floods. Sometimes, there may be light rain but fall for many days can even result in floods.

2. River overflow

Rivers can overflow their banks to cause flooding. This happens when there is a huge amount of water upstream than usual, and as it goes downstream to the adjacent low ground areas, there is a burst and water flows into the land.

3. Strong winds

Massive hurricanes and winds can flow seawater into dry coastal lands and lead to flooding. Sometimes this becomes worse if the winds carry rains themselves.

4. Snow melts

In several cold regions, heavy snow in winter usually stays solid for some time. There are also so many mountains that have ice on top. But sometimes the snow suddenly melt when the temperature increases, resulting in a huge movement of water into places that are dry. This is called a snowmelt flood.

5. Clogged drainage

Flooding can also take place when rainfall runoff snowmelt cannot be channeled properly into the drainage system allowing the water to flow overland. The place remains flooded till the waterways or stormwater systems are rectified.

Human-made causes:

1. Broken dams

Dams are man made huge blocks made to hold water flowing down from a high ground. The Power in the water is utilized to switch propellers to produce electricity. So many times, too much water collected in the dam can cause it to burst and overflow the area.

Excess water can also be released from the dam intentionally to prevent it from bursting and that to cause floods.

2. New construction and land development

New construction on unused lands affects the natural drainage of that area. With more land belong to construction for new buildings and homes, there is less land to absorb water. This makes such areas more prone to flooding.

By knowing and understanding the natural and human-made causes that lead to flooding, help you can reduce your risk and work accordingly. If your building or home experiences flood damage, contact a professional for water damage restoration.
