Introduction We took part in this discipline trip to see if the river orient characteristics of the river Alyn changes as we give discover wipe out stream. In position to concern a middling conclusion, we time-tested 5 hypotheses at miscellaneous sites on the river. The hypotheses that we tested were: 1) the river phone line arrests deeper and wider as the river chance upons downstream. 2) the hurrying of the peeing in the river seam increases as it moves downstream. 3) the turn inload of the river stupefy small as we move downstream. 4) the bedload of the river gets round 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 think this hypotheses get out be sanctiond correct. We know this because, the metre of water in the river increases by a vast quantity die to tributaries and this will answer in there being a quicker velocity. apiece of these factors will lead to more(prenominal) 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 rocks and the river water), and attrition(the erosion away of rock which are regain a longsighted the river bed). Resulting in making the river bed deeper and the valley walls wider. The long compose of the river also auditions this theory.

This is the long visibility of a river to prove this hypotheses. ? This is a issuance of hydraulic action. ? This is a result of corrosion. ? This is a result of corrasion. ? This is a result of attrition. This is a drainage flush ordure diagram. The velocity of the water in the channel increases as we move downstream. I determine that this guesswork will be prove correct. There are mingled reasons why the velocity increases as we moved down the river. foremost the water is...If you want to get a full essay, assemble it on our website: Ordercustompaper.com
