Sand and boulders prevent the river from changing the course and act as a buffer for the riverbed. Excessive in stream sand mining is a threat to bridges, river banks and nearby structures in the study area Sand mining also affects the adjoining groundwater system. Determining the sand budget for a particular stream reach is solution but for this following information is required like site-specific topographic, hydrologic, and hydraulic information. With this information we can estimate the amount of sand removal in upstream and downstream area of the bridges. To control sand mining the miner should have licence. Illegal operation should be stopped. Government guidelines should be followed by the miners.
