Land erosion ultimately affects the physical and chemical properties of soils and resulting on-site nutrient loss and off-site sedimentation and nutrients enrichment of water resources. The off-site effects of erosion in the form of sedimentation and nutrients enrichment are usually more pricey and severe than the on-site effects on land resources. Many empirical equations and procedures have been developed for estimating sediment yield at the outlet of a catchment. These regression equations for estimation of annual sediment yield are linked with catchment area, land use patterns, meteorological conditions and runoff generated within the catchment. These equations are widely accepted and used for prediction of sediment yield from the un-gauged catchment area. In the present study Upper Lake, Bhopal and its catchment area is taken as a test case and entire study was aimed with two main objectives, first, to estimate and compare the annul sedimentation yield using different empirical equations and second, to determine the sediment characteristics deposited in the bottom of the Upper Lake. The study results revealed that significant annual sedimentation yield were observed which were found in between 0.22-5.6 Mcum/year. As far as, sediment characteristic is concern, it was also found rich in nutrient and organic loads which may be the significant nutrient contributors to hypo-limnetic lake environment. Therefore, an integrated catchment area plan is imperative which can manage on-site effect of soil erosion that could reduce the risk and negative impacts on downstream Upper Lake ecosystem.
