Imperious Approach Towards Justifiable Strategic Lake Sediment Regulation
2020
Shekhar Salunke and Balbhim Chavan
Lakes are extremely appreciated for the ecological, aesthetic and recreational values supporting rich biodiversity. As such, their preservation is of supreme importance. A global common problem of sedimentation that eventually seems to be responsible for eutrophication should be immediately attended to, before the degradation begins, since the restoration measures are expensive and may go beyond control. Erosion causes detachment, transportation, and deposition of sediments and is the prime source of contamination where it accumulates in lakes and interrupts the ecological processes and functioning in the lake ecosystem, hence it is important to determine the risk to design management strategies for control. For the present investigation, thematic layers slope identification, NDVI, LULC, lineament density and RUSLE were employed to compute spatially distributed erosion and contaminant sources for the lake Ekrukh of Solapur district of Maharashtra State, India. The research identifies five hazardous erosion zones as; low, moderate, high, very high and severe, through the applied model and dictates formulation and implementation of innovative control strategies preventing soil and water (surface) pollution. The Soil Erosion in Maharashtra, Technical Bulletin, 2001 (Challa et al. 2001) was also referred to for the studies.
