The content of this article has been abstracted from the independent report “Possible ways to control floods and its effects on dry land”, available to download using the link at the bottom of this page.
This article explores possible ways to control floods and its effects on dry land. Every year, some parts of the world get's flooded by natural disasters such as, frequent rain/storm and rise in sea level due to global climate change.
There have been some global debates on controlling the environmental activities to prevent climate change and natural disasters. The reality is that climate change cannot be controlled, other than to slightly slower the process by making changes to the environmental activities. However, by being smart the impacts of climate change on earth surface can be reduced and tackled to a certain extent.
The severity of floods, depends on the several factors stated below.
• Volume of rain fall in a particular area at a time
• Length and frequency of rainfall/storm
• Location (i.e. higher or lower land)
• Strength of the wind (The stronger the wind, the more water gets pushed further up the sea shore, affecting dry land)

Can floods be controlled?
There are a few possible ways that flood could be controlled to a certain extent but not prevented.
1. More empty lakes - Digging up large and deep empty lakes on empty lands near the frequently affected areas. This approach could possibly help to reduce the level and effects of floods on dry land.
2. More empty rivers/streams - Addition of more empty rivers/streams through frequently affected areas connecting to empty lakes. This approach could possibly prevent some minor floods and also reduce the level of water above on dry land during major floods.

3. Empty streams beneath pavements and roads – Digging up deep streams like trenches beneath the pavements and in the center of the roads, covered with steel mesh covers on the top for pedestrians and vehicles to use. This approach could possibly prevent some minor floods and reduce the level of water above the ground during major floods.
4. Building properties above ground level – Properties could be built a few feet above the ground level with waterproof material at ground level, to prevent large volume of water entering into the properties during floods.
However, these are just a few thoughts on reducing/preventing the rise of water level and the effects of floods and not fully eliminating the effects of major floods caused by natural disasters around the world. There are no proven supporting evidence to the content of this report. It might ideal for civil engineers and construction workers to look into this in greater detail.
