Unit Hydrograph and Storm Hydrograph
Unit Hydrograph:
A unit hydrograph is defined as the hydrograph of direct runoff resulting from one unit of excess rainfall that is uniformly distributed over the watershed at a uniform rate for a specified duration. The unit hydrograph of a specified unit duration obtained from the past data can be used to obtain the hydrograph of future storms of like duration. Unit hydrograph is a very important tool for hydrologic analysis and design of hydraulic structures.
Storm Hydrograph:
A storm hydrograph is the hydrograph of direct runoff resulting from a particular storm of known rainfall depth, duration and distribution over a watershed. To obtain the ordinates of storm hydrograph, the ordinates of unit hydrograph are multiplied by the multiplying factor. The multiplying factor for storm hydrograph may be obtained by dividing the runoff in mm by 25 mm. It is important to note that the multiplying factor is based on the assumption that the excess rainfall is uniformly distributed over the watershed and the time of concentration is the same for both the unit hydrograph and the storm hydrograph.
Tolerance of Unit Hydrograph:
A tolerance of about 25% of specified duration of unit hydrograph may be accepted without any serious error. This means that the unit hydrograph of slightly different duration may be used for the design of hydraulic structures without much error. However, caution should be exercised when using a unit hydrograph of significantly different duration.
Conclusion:
In conclusion, the unit hydrograph is an important tool for hydrologic analysis and design of hydraulic structures. It can be used to obtain the hydrograph of future storms of like duration. The storm hydrograph can be obtained by multiplying the ordinates of unit hydrograph by the multiplying factor. A tolerance of about 25% of specified duration of unit hydrograph may be accepted without any serious error.
