The subject of river sediment transport has been studied from centuries - by river engineers as well as geographers, geologists, river morphologists and fluvial geomorphologists. Up to now there are no well known complex methods and/or approaches with help of which one can determine the intensity of sediment transport. However, even the approximate knowledge of the quantity of sediment transport is important, especially when dealing with sedimentation of river deltas, and lakes, designing artificial water reservoirs and planning any river engineering works or designing hydraulic structures. The appropriate assessment of the intensity of sediment transport has the direct influence on an adequate functioning of any hydraulics structure or object, with the help of which the negative influence of sediment transport is eliminated (erosion, channel cutting, filling-up river and water reservoir water intakes). One has to bear in mind that all phenomena connected with sediment transport are very complicated and complex and belong to the most poorly recognized in river hydraulics, thus the best way to understand them is to do measurements directly in the field. This is especially recommended for mountainous streams and rivers. However, in practice, when we suffer the lack of huge financial support (since all river measurements ...
