.Explain how human and physical factors can increase flooding (6 marks) ​

Human factors increasing flood risk: urbanisation , because towns and cities have more impermeable surfaces. deforestation , because removing trees reduces the amount of water intercepted and increases run-off.

•Physical factors are below:
heavy rainfall.
long periods of rain.
snowmelt.
steep slopes.
impermeable rock (doesn't allow water through)
very wet, saturated soils.
compacted or dry soil.

let's divide the figure into two parts.

radius of the semicircle is 3.5m. two semi-circles make a circle and

area of circle=pi×r²

area of circle=22/7×(3.5m)2².

area of circle=38.5m²

area of rectangle=length ×width

area of rectangle =18m×7m

area of rectangle =126m²

area pf figure =38.5m²+126m²

area of figure=164.5m²
