Flooding in the uk (somerset levels, 2014)
why does flooding happen:question:
Hard Baked Soils
When the earth is hard from sunlight so when the rain comes it will have a harder time soaking in to the ground
Impermable Surfaces
This means the water wont soak into the object shuch as the tabe is impermiable where as soil is permiable
Low Lying ground
Vallys that are below ground level and collect water
Steep Vally Sides
Deforistation
Trees intercept the rain and we get smaller drops that are easily soaked up. Houses are impermiable so water is not stopped
Urbanisation
Urbanisation is the increase of people living in cities. This increases flooding because
Saturated Soils
Soils toataly full of water like when a sponge is full of water the water would run off eventually
impacts of the 2014 flooods
Enviromental
14k hecters of land covered in water for 3-4 weeks
1k livestock evacuated
Flood waters contaminated with suage, oil and chemicals
Ecenomic
16 farms evacuated
600 houses flooded
Cost being 10 million pounds
water was pumped bact to rivers
Social
16 farms evacuateed
resedents in acomidation for months
Roads cut by debris and floods
railways closed
villages
Imidiate and Long term responses
Imidiate
Villagers cut off by the flooding use boats to get to school or shop for food
locaL community groups and volenteers gave invalueable support
long term
Incresing river capacity by beion derdged
river banks being raised and strengthened
Roads raised in places to maintain floods
by 2024 consideration will be givern to tidal barrage at Bridge water
Vaunrable communities have flood defences
using evidence from this map
somerset is prone to flooding because there are too many rivers and the ground is low lying
