Extensive radar ice-thickness sounding of ice streams A, B, and C, and the ridges between them, has been carried out. Closely spaced flight lines, as well as ties to numerous ground stations, have enabled us to compile a detailed ice-thickness map of the area. The map reveals a highly complex pattern of ice-thickness variations, which, because they are much larger than the surface relief, largely reflect the subglacial topography. Several cross-sectional profiles across the ice streams and ridges are shown, and a new configuration for Ice Stream A is presented.Ice Stream A is connected to Reed

The article deals with the processes of slope erosion, leading, in particular, to emerging a gully, its most dangerous type. The concentration of this process’ products in certain places on the slope leads to increased soil destruction and formation of narrow extended gaps, which quickly turn into wide ones. The ravine continuously increases in size as the destroyed soil is constantly carried out of it. Any known methods of combating this, to one degree or another, boil down to creating protective barriers which prevent liquid products of planar soil washout from entering the ravine. That is w

Scour is the process of local lowering of stream bed elevation which takes place in the vicinity or around a structure constructed in flowing water. Scour takes place around bridge piers, abutments, around spurs, jetties and breakwaters due to modification of flow pattern in such a way as to cause increase in local shear stress. Due to improper knowledge of scour around bridge pier, there were lots of bridges failure cases faces by our country which leads to economic loss and life loss.
