... significant mass imbalance is created between the zone of accumulation and ablation. Glacier movement is most likely to be produced by imbalances between glacier inputs and outputs causing the snout to advance across the firn line. There will be significant ...

... ice crystals face the direction of the movement so they can slip past each other therefore the surface of the glacier moves faster causing deep crevasses. Temperate glaciers are in areas with milder summers and steeper slopes. The base is almost ...

... than those at the bottom. 3. the slope at the top of the "wadi" is "v-shaped". 4. the slope at the bottom of the "wadi" is "u-shaped". 5. weathering is more common at the top, as there is more exposure. 6. the angle of ...

... into debt. Of the 126 million people living on this south - Asian delta, 83% of them live in rural areas, mainly farming rice and wheat on fertile areas of land, which are unfortunatly prone to flooding each year. Most ...

... the lower/middle course of the river. It also has little human influence making it relatively natural. I have selected to study Backstone Back since it is a tributary of the River Wharfe and therefore more accessible than the source. ...

... (how many rocks and boulders are found in the river channel) the more obstacles there are opposing the waters flow leading to increased friction and decreased velocity. The channel is less rough the further you go downstream and so the ...

... the river hemmed in by steep cliffs and heavily wooded slopes which tower over it, while the stream glides lazily through turbid pools. At the two cliffs known as the Celestial Twins you enter Wolfscote Dale, which continues down to ...

... steeper the slopes the lower the rate of infiltration and the faster the rate of runoff when the soil is saturated. 2. ROCK TYPE- run off will occur quickly where the impermeable rocks are exposed at the surface or quickly when ...

... It can protect your home from flooding as well as from the force of water from rivers. A properly built levee takes a lot of space. Its sheer mass keeps it from moving. Long, gentle side slopes increase stability and provide ...

... a landform formed from the deposition of weathered and eroded surface materials. On occasion, these deposits can be compressed, altered by pressure, heat and chemical processes to become sedimentary rocks. This includes landforms with some of the following geomorphic features: ...

... are subjective. * No site 8 results like the results that were recorded previous, resulting in totally inconclusive results. * Controlling methods - velocity and depth were measure by hand which could be inaccurate (i.e. site 3's depth of 25cm compare ...

... moves approximately 300m per year. It is the basal temperature that determines the mechanism of movement. In what follows I will explain the factors influencing different mechanisms of movement. Temperate glaciers move mainly by basal sliding. If the basal temperature is ...

... at 1800nC, the relationship between the rate of discharge and the number of taps to be a base 10 exponential relationship. This can also be expressed by the equation (q being the charge n being the number of taps). There ...

... There are large areas of moorland in the uplands, particularly to the West of the Ouse. Moor land 'Gripping' (grips are drains) was carried out extensively in the Swale, Ure and Ouse catchments in the 60's and 70's, the consequence ...

... there are no external inputs or outputs into, so these do not have to be taken into consideration. Humans affect the cycle both intentionally and unintentionally in many ways. The stores are affected by the removal of vegetation, the melting of ...

... 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 ...

... is a lot of it then the hydrograph is likely to have a high peak discharge where as if the precipitation is low-intensity and there is a small amount then the graph will have a gentle ascending limb. The ...

... a highly permeable material such as sand tends to give low drainage density because of high infiltration capacity and little water is available as surface runoff to maintain channels. * Rock type * Topography * Vegetation- dense vegetation helps to intercept rainfall, because ...

... and deeper. The land, which the river flows over, is becoming flatter and this is where the river starts to meander or bend in the middle course. The lower course is where the river becomes its widest and deepest. This ...

... small rural village of Tal-y-bont, which was near the town of Aberystwyth. The river that we decided to test out with our hypothesis and find out our aim on was the river Einion. The river Einion is a tributary to ...

... Does Landuse on the banks influence the planform shape? Turbulent flow is the major flow type in most natural river channels. It is this which justifies their efficiency in both the eroding and transporting of materials and sediment. The velocity ...

... increase the discharge of lower course of Huang He, allowing the floodwater to overflow its banks. The climatic condition throughout the year leads to the occurrence of flood. Topographically, there is a sudden decrease in gradient at Kaifeng, between ...
