The trap efficiency of a reservoir after commissioning will -
Decrease with time
As sedimentation occurs and the reservoir's effective volume decreases, the amount of time water spends within the reservoir also decreases for the same inflow rate. This reduction in capacity means that for the same inflow, the water velocity through the reservoir increases, and the residence time decreases. Therefore, the correct answer is Decrease with time.
