ing with the Rational Method for peak discharge in the. 19th century, progressing to the unit hydrograph in the. 1930s, and then to more recent use of dimensionless or index hydrographs. The empirical relations are simple elements from which a hydrograph may be made as complex as needed. Difficulties with hydrograph
Base flow separation. • Surface runoff hydrograph derived by separating base flow from hydrograph. • Straight line method. – Join the starting and end points of surface runoff by straight line. – Area under the straight line is base flow
UNIT HYDROGRAPH ANALYSIS. Sherman (1932) first proposed the unit hydrograph concept. The Unit Hydrograph. (UH) of a watershed is defined as the direct runoff hydrograph resulting from a unit volume of excess rainfall of constant intensity and uniformly distributed over the drainage area. The duration of the unit

A hydrograph is a continuous plot of instantaneous discharge v/s time. It results from a combination of physiographic and meteorological conditions in a watershed and represents the integrated effects of climate, hydrologic losses, surface runoff, interflow, and ground water flow. ? Detailed analysis of hydrographs is usually
LECTURE 6 RUNOFF AND HYDROGRAPH ANALYSIS At the end of the week, students should be able to: draw the resultant hydrograph based on catchment characteristics and rainfall – runoff conditions; state and apply base flow separation techniques and estimate direct runoff values; derive Unit Hydrograph from
Analysis of peak rate of runoff, volume of runoff, and time distribution of flow is fundamental for design of highway drainage facilities. Most drainage facility designs require determination of a peak flow rate while others require a runoff hydrograph that provides an estimate of runoff volume. Peak flow rates are most often used

The analyses resulted in a relation that can be used for estimating storm peak discharge based on drainage area, basin-average rainfall, and impervious area. Average unit hydrographs were developed for. 24 of 25 streamgaging stations, using from three to nine storms at each site. The average unit hydrograph for.
