Triangular hydrograph

WebFeb 22, 2024 · The total synthetic hydrograph is the result of aggregating corresponding ordinates of the three triangular hydrographs. Each of these three triangular hydrographs has its own characteristic parameters, namely time to peak, recession constant, and fraction of an effective rainfall volume allocated to the triangle. http://onlinemanuals.txdot.gov/txdotmanuals/hyd/hydrograph_method.htm
