Description Runoff and sediment flow behaviors from small agricultural watersheds on Alfisols and Vertic Inceptisols,
and their implications for the design of a runoff and soil loss monitoring unit are discussed. It was
observed that a small segment of runoff hydrograph near peak discharge rate usually accounted for
65–85 percent of total storm soil loss. The runoff and sediment flow behavior recorded on the small agricultural
watersheds indicated the need for an integrated digital runoff and soil loss monitoring unit
(IDRSMU) to achieve higher accuracy and cost effectiveness. The design, development and testing of an
IDRSMU to measure both the runoff and soil loss from small agricultural watersheds is presented.
Under the field conditions its accuracy and efficiency for monitoring soil loss from small agricultural
watersheds was observed good. Use of this integrated unit, makes the estimation of soil loss easy, rapid
and accurate. The designed unit does smart runoff sampling by linking the runoff sampling intervals to
the sediment load. This significantly reduces number of samples that needs to be collected, thereby
reducing the operational cost, without compromising with the accuracy in estimating soil loss from small
agricultural watersheds.
