where is pickering beck located
- runs through north Yorkshire
- follows a course alongside Yorkshire moors railway
- approaches town of pickering from the north
catchment of the beck is..
the beck flooded the town in..
1999, 2000, 2007
in the 2007 flood..
- 85 buildings were flooded
- main A170 road flooded
- damage cost of £2.1billion
natural causes of flooding include..
- soil type (peat is quickly saturated, gritstone is impermeable)
- relief of land (steep basin so floods quicker)
human causes of flooding are..
- agriculture: animals constantly trampling ground so ground becomes less permeable
- ploughing creates easier surface runoff routes
- urbanisation = impermeable ground
- vegetation removal
the Beck has failed to meet ‘good water status’ in terms of quality, why?
farming and agriculture has had a negative impact
some management strategies used?
- low level bunds
- floodplain woodlands
- restoration of large wood debris dam
- no burn zones
- educating locals/farmers
construction of low level bunds
- bunds put in are 2m high
- have added an additional 120,000 cubic metres of water storage to the Beck
- intercept a lot of water and increase infiltration and transpiration
- doesn’t harm environment
- takes a long time to grow trees
- not the most effective way
restoration of wood debris dams
- slow the water flow down
- all time is longer so reduces flooding
- doens’t have a massive impact
no burn zones
- increases interception and transpiration so slows down flooding
- not easy to monitor
- limited impact
- people are more aware of ways which they can help or protect their land
- not everyone will listen
