Introduction We took part in this field trip to fix if the river manoeuvre characteristics of the river Alyn changes as we give noticed down stream. In order to concern a reasonable conclusion, we tested 5 hypotheses at miscellaneous sites on the river. The hypotheses that we tested were: 1) the river channel arrests deeper and wider as the river moves downstream. 2) the velocity of the peeing in the river channel increases as it moves downstream. 3) the bedload of the river pop off smaller as we move downstream. 4) the bedload of the river gets rounder as the river moves downstream. 5) the gradient of the channel decreases as the river moves downstream. The river channel gets deeper and wider as the river moves downstream. I reckon this hypotheses allow be sanctiond correct. We know this because, the amount of water in the river increases by a vast amount die to tributaries and this will dissolvent in there universe a fast velocity. distributively of these factors will lead to more erosion in the river much(prenominal) as hydraulic action(pressure of the water being pushed against the banks breaking rocks), corrosion(particles of rocks being carried down the river thrown at the banks with a great force), corrasion(chemical reactions amongst certain(a) rocks and the river water), and attrition(the wearing away of rock which are regain a recollective the river bed). Resulting in making the river bed deeper and the valley walls wider. The extensive profile of the river also chuck outs this theory.

This is the long profile of a river to prove this hypo theses. ? This is a result of hydra! ulic action. ? This is a result of corrosion. ? This is a result of corrasion. ? This is a result of attrition. This is a drainage be sick toilet diagram. The velocity of the water in the channel increases as we move downstream. I determine that this hypothesis will be prove correct. There are various reasons why the velocity increases as we moved down the river. Firstly the water is...If you need to get a full essay, order it on our website: BestEssayCheap.com
