Current Research Abstract Debris flows are common in mountainous areas throughout the world. Often triggered as mudflows by torrential rains, debris flows contain varying amounts of mud, sand, gravel, boulders, and water flow down along a stream at high speed. Because of its high density and speed, it has huge destruction power. In mountain torrents, intense and localized storms may cause flash floods with important sediment transport. In steep torrents, the sediment that are the deposited on the alluvial fans, often highly populated in the case of debris flow that transport downstream huge volumes of sediment, the sediment discharge may increase so that the solid concentration often exceeds figures 40-50%. It is necessary to investigate the debris flow and its soft and hard countermeasure, in order to manage the sediment disaster in the river basin and prevent the downstream hazards. The comprehensive assessment of debris flows countermeasures both structural and non-structural requires the consideration of the various scenarios and involves the evaluation of hydrological, hydraulic, sediment size distribution and topographical parameters. Debris flow modeling and its structural countermeasures by check dam can be done with the help of experimental study and numerical models. Check dams are one of the effective structural counter measures for debris flow control. The main objectives of the current research are the study on debris flow and its structural and non- structural countermeasure, development of numerical models and mechanism, experimental study on debris flows and preparation of debris flow hazards mapping.
