WebSnyder’s Synthetic Unit Hydrograph. The synthetic unit hydrograph of Snyder (1938) is based on relationships found between three characteristics of a standard unit hydrograph and descriptors of basin morphology. The hydrograph characteristics are the effective rainfall duration, t r, the peak direct runoff rate, q p, and the basin lag time, t l .
