How the Tee's Environment Influenced the the Use of Land
The Rivers Tees?s estuary has a large area of low-lying mud flats so wildlife and birds mainly used the area before 1994. Over time since 1906 inter-tidal land has been reclaimed, this adds to the overall area of the estuary. There are several sites of scientific interest in the estuary including seal sands, up to 200,000 migrant birds visit the sites of scientific interest in the autumn. With all the land that has been reclaimed the estuary has an area of around 8km squared in total, this provided a perfect area for building in the lower section. i.) The physical environment; The Tees Barrage has changed the level of water upstream which may distress the fish living there. The speed of the river upstream may change so the erosion rates and the amount of sediment the river deposits may alter. Bellow the Barrage the water level has raised which has submerged the shallow areas and the inter-tidal sites of scientific interest. The water quality and salinity have been improved with the level of dissolved oxygen increasing rapidly upstream at the Tees Barrage the level has doubled since 1992/1993, downstream the levels have increased slightly since the Barrage was in place. Also the ammonia concentrations have been reduced to almost nothing upstream and have been reduced dramatically downstream, this improves the condition for the fish living there. Although the amount of Waders has been reduced by around half from 2166 birds visiting to1157. The oystercatchers are the only species of bird which have grow in numbers since the Barrage has been built this may be due to the improved water quality so there will be more oysters for the birds to eat. Since the Barrage has been built the river discharge upstream has been reduced and calmed down, the discharge only alters slightly from day to day where as before the discharge changed rapidly with may have led to floods. ii.) The human environment; Since the Barrage has been built the town has invested £500 million in new offices, which creates more jobs for people living in or around the town. Houses, which increases the town?s population because people will buy the new houses and move to the town. University residences and buildings which helps promote the town?s university to perspective students and make the town more appealing if there is more accommodation. Retail and leisure parks, which increase the amount of shops and the amount to customers coming to the town to shop or be, involved in leisure activities, The town now has white water canoeing course so people will travel to the town to participate in the activity. With the water quality improved there are more fish, so fishers are attracted to the town, this improves the town?s income. The Barrage has lead to various new activities for people to participate in.
