WebThis tool can be used to calculate the sediment transport index (STI) described by Moore and Burch (1986). This index is derived from unit stream-power theory and is sometimes used in place of the length-slope factor in the revised universal soil loss equation (RUSLE) for slope lengths less than 100 m and slope less than 14 degrees.
