Answer 2

The river Tees is what is called a flashy river it could flood very quickly. The Tees rises on the slopes of Cross Fell at a height of 893m. It is in this are where there is 2,000mm of rainfall a year. The rainfall reaches the river quickly because this area is made of impermeable rock and saturated peat so very little water can seep into the ground, so the water then runs off down the slope into the river. After heavy rainfall this happens rapidly and there is a huge surge of water downstream, this usually occurs in winter because there are many storms where there can be cloudbursts. Moreover due to the harsh conditions in winter a majority of trees reduce their rate of transpiration, so leaves catch less rainfall and roots absorb less water. In spring there are a lot of flash floods due to heavy snow during the winter. The snow on the ground melts and the melt water then runs off into the river.
