Why do you have storm drains?
To reduce and control urban flooding.
How does urban development increase flooding?
Urban development can increase flooding by replacing natural areas like forests and wetlands with impermeable surfaces like concrete and asphalt. This prevents rainwater from being absorbed into the ground, leading to increased runoff and overwhelming drainage systems. Additionally, urban development can disrupt natural water flow patterns, exacerbating flooding in downstream areas.
How can the effects of flooding be reduced?
by not building on flood plains and building rock defences to keep the waves of land!

The occurrence of floods in urban areas is particularly dangerous because?
Flooding in urban areas is dangerous because there are larger populations in these areas. There are also more businesses and facilities, so floods would have a greater economic impact.
What are relief channels?
An alternative route for floodwater (discharge) to travel rather than flooding an area that will cause negative impacts (e.g. urban area)
Why flooding is more likely to occur in urban areas than wooded rural areas?
Flooding is more likely to occur in urban areas due to increased impervious surfaces like pavement and buildings, which prevent water from infiltrating the ground. In wooded rural areas, vegetation and soil can absorb and slow down water flow, reducing the risk of flooding. Urban areas with high population density also have more development in flood-prone areas, further increasing the risk.
What practice has reduced the amount of fertile farmland available?
urban sprawl, also known as suburban sprawl, is the spreading of a city and its suburbs over rural land at the fringe of an urban area.
What are the diseases of flooding?
When there is flooding in an urban area, the sewage system floods as well and raw, untreated sewage contaminates the floodwater. So any disease that is spread in faeces is a risk in flooding. Usually the diseases spread in this way are cholera and typhoid but there may be others.
