Water flows faster and is deeper on the outside edge of a meander curve

Extracts from this document...


Geography Coursework Introduction - Aims and Objectives Purpose of study and general theory The purpose of this study is to decide whether the hypothesis 'water flows faster and is deeper on the outside edge of a meander curve' is true or not. To do this I have collected a lot of data about the river Wye. I will use this data such as bed load samples, width of the river depth of the river to create cross sections, velocity (measured in 2 different ways), and gradient. I will also use field sketches and maps of the areas. The field sketch on the following page shows Group 3, Site B. This is an example of a hand drawn map of the area that we studied. In it there is all the relevant detail that we could see these are things like where we saw the biggest sediment, if there was any overhanging branches or vegetation at the edge of the river. We also identified if it was possible (in some cases we couldn't see) ...read more.


I will also be doing field sketches and finally I will find the gradient. I will then go on to do another site (all these things are explained in more detail in the method). I will then do the write up and analyse the data to find the aim of the experiment. My question is 'does water flow faster and is it deeper on the outside edge of a meander curve' and I think that the water will flow faster on the outside edge of a meander bend. I think this because the general theory behind this investigation proves this. This is the general theory, water tries to go in straight lines and so when it comes across a meander it carries on going straight. This causes the water to flow to the outside edge of the meander. The fastest flow of a river is, on a straight river is in the centre. This is because they wear away more sediment and don't deposit very much sediment and so there is less friction between the water and the bed because it is deeper in the middle. ...read more.


Water erodes sediment in four major ways, these are, 1) Hydraulic action; Is when water is forced into the cracks in the banks and/or bed of the river and enlarges them. 2) Attrition; This is when sediment within the water is stuck by other sediment, this breaks them up and wears them down. 3) Abrasion; Is when water throws the sediment in the water against the bed and/or banks, this breaks them up and wears them down. 4) Solution; This means that water dissolves the rocks that make the bed and banks up. This only happens with soft rocks like limestone. The fast water erodes the sediment much faster that slow moving water so all these methods of erosion will speed up. This after a long period of time will in fact cause the outside edge of a meander to be a lot deeper than the rest of the river. This will also cause the river to flow even faster on the outside edge of the meander because there will be even less friction between the water and the bed and sides. This theory shows that water should normally flow fastest and be deeper on the outside edge of a meander. ...read more.

    There are two parts to this hypothesis. Firstly there is the size of material and secondly, there is the angularity of the material. These are best dealt with when split separately. This is so that more clarity can be provided in understanding the influences that affected the size and angularity of material at the river Skirfare at the two locations.
