                             Flood

The effects of flood damage can be categorized into three types, namely, primary, secondary and tertiary.


The primary effects of flood damage include physical damages like damage to bridges, cars, buildings, sewer systems, roadways, and even casualties like people and livestock death due to drowning. The primary effect of floods is due to direct contact with the flood waters.

The secondary effects of flood damage are the disruption of many essential services like gas and electricity. Flood damage also includes the contamination of the drinking water supply, if sewage treatment plants are flooded. This poses a greater threat because this may result in disease and other health hazards, especially in under developed countries.
