Abstract: | The problem of alluvial transit across watercourses presents great theoretical and practical importance. The outflow of alluvia represents the effect of the erosive activity exercised by running waters and reflects the erosion potential of the hydrographic network, with direct effect upon the general evolution of the forms of relief and of the geographical morphology, in general.
The analysis of the regime of alluvial outflow can offer precious information on the local and regional conditions of denudational processes, determined, in their turn, by environmental conditions (geology, relief, hydro-climatic and bio-geographical factors) and by the dimensions of the anthropic impact.
From a practical point of view, the knowledge of solid transit is of vital importance in projecting complex arrangement or flood protection works. There are numerous cases of accumulation lake clogging (respectively, of decrease in their efficiency and effectiveness), of water supply sources for utilities and irrigation or dragging canals, of exacerbation of the riverbed erosion). |
