WebThe estimation of peak flow and volume of runoff can be done using various empirical formulae, unit hydrograph theory or from probability of occurrence of floods based on frequency concept. Factors Influencing Peak Flow: Factors which influence the peak flow can be divided in two categories: a. Basin characteristics, and b. Storm characteristics. WebNov 17, 2024 · The main outlets of karst systems are springs, the hydrographs of which are largely affected by flow processes in the unsaturated zone. These processes differ between the epikarst and transmission zone on the one hand and …

WebFeb 6, 2016 · From the above equations, Tr = 1 hr and unit rainfall excess Re = 10 mm are used for calculating the peak discharge. A triangular unit hydrograph matched with a design hyetograph is utilized in this study as the numerical simulation condition for estimating the inflow runoff hydrograph of the potential debris flow torrent in Ershui Township. WebEach HydroCAD summary and hydrograph plot lists the peak flow(s) attained during the routing. This is an interpolated value, and is generally somewhat higher than the maximum flow shown in the tabular hydrograph. The peak value is obtained by taking the peak of a parabola fitted to the three highest points. This is the same technique used by TR ... by owner homes for rent
