Floods!!!

That is most likely the other far extreme of droughts. Floods can be literally translated as excess water, either from streams over flowing their banks or from excess run off.

In the natural water cycle, precipitation and infiltration are meant to play the major roles in removing excess water and the chief of this is infiltration. Defined as the movement of water into the soil, it is affected by different factors or infiltration characteristics. When the rate of precipitation exceeds the rate of soil infiltration, the we are likely to have excess water and in most cases leads to flooding. Chief of these soil characteristics affecting rate of water movement in the soil is the soil structure which has in most coastal cities been distorted from its natural free moving form. An understanding of the soil structure along with other soil properties can help in developing models that predicts flooding right from its cause factor. As Urbanisation increases to the needs of the growing population. There is bound to be a gross deviation from the natural when it comes to infiltration and soil properties affecting it.

A better understanding of theses properties will be a rewarding approach towards prediction and hence mitigation.
