Abstract

Rivers are completely dynamic and active systems. In this study, we have investigated the effects of GRAVEL MINING on river MORPHOLOGY in Dehbala River of KERMAN. First, basic researches including physiographic, geological, meteorological, erosion and sediment studies were conducted, then MORPHOLOGY of Dehbala River was studied using time- location comparison method. River bed was digitized by ILWIS software, in three periods of time, using the aerial photos of 1989, 1999 and satellite image of 2006 from river bed, and then geometrical parameters of river such as wavelength, the coefficient of curvature, relative radius and central angle was computed by AutoCAD software to evaluate changes, using fitting circles tangent method. According to the situation of gravel mines, the drainage path was divided into 4 pieces and then these parameters and changes were compared along the river. Changes in central angel demonstrate increased meandering from 1989 to 2006. According to the coefficient of curvature index, curvature of river was increased in this period. Increase in wavelength and length of valley of the river show increase in maneuverability of the river. Decrease in central angle of the river from 1989 to 2006, demonstrates increased instability of the river and subsequently development of lateral erosion. Width of bed shows the most changes in comparison with the other parameters. Piece 2 shows more changes in width of bed, which can be caused due to locate gravel mines in this piece and subsequently direct derivation. Finally, morphological changes of river was few and probably due to presence of large amounts of sand and gravel, the effects of GRAVEL MINING were short-term, but because of decreasing trend of rainfall and consequently decrease in bed load, more caution in gravel and sand mining is required…
