The need for replenishment study for river bed sand is required in order to nullify the adverse impacts arising due to excessing sand extraction. Mining within or near riverbed has a direct impact on the stream’s physical characteristics, such as channel geometry, bed elevation, substratum composition and stability, in-stream roughness of the bed, flow velocity, discharge capacity, sediment transport capacity, turbidity, temperature etc

We do replenishment study by following method

a) Physical survey of the field by the conventional method
b) Use of UAV/Drone and other image data processing techniques

We have in-house team of drone pilot and processor. We have number of UIN registered drone for replenishment study. We have done more than 1000 replenishment study for sand mining in various state like Uttar Pradesh, Madhya Pradesh, Haryana and Bihar
