Flood and Drought Causes and Effects

Study Notes

Flood Causes

Heavy rainfall is the primary cause of floods, especially during intense storms like hurricanes or tropical storms.
Excessive water overwhelms river banks and causes dams to overflow during heavy rainfall.
Poor farming techniques, like removing vegetation, leads to soil erosion which increases flooding.
Eroded soil in rivers and dams can increase water levels.
Removing trees and forests leads to soil erosion, which increases flooding.
Trees' roots hold soil firmly in place, preventing erosion.

Drought

A drought is a prolonged period without enough rainfall.
Droughts can lead to water shortages, crop damage, reduced stream flow, and lowered groundwater levels.
Insufficient rainfall or snow is a major cause of drought.
Exceeding the available water supply also contributes to droughts.

Drought Effects

Droughts negatively impact various aspects of life.
Water scarcity leads to losses in agriculture, reduced availability of water for livestock, and insufficient drinking water for humans and animals.
Drought reduces plant growth, impacting crops negatively.
Reduced water flow in rivers and streams is a result of drought.
Groundwater levels significantly decrease during droughts.
Droughts have a major negative impact on agriculture.

Water Conservation

Water conservation is crucial during droughts.
Simple actions, like turning off the tap while brushing teeth, can significantly reduce water waste.
Repairing leaking faucets can prevent water wastage.
