Unit Hydrograph and Unit Storm
Unit Hydrograph and Unit Storm
A unit hydrograph is a hydrograph of direct runoff resulting from a unit depth of excess rainfall that is uniformly distributed over a drainage area at a constant rate for a specified duration. The unit hydrograph is a fundamental tool for hydrologic analysis and design of hydraulic structures. On the other hand, the rain during the specified duration is called a unit storm.
Unit Duration and Runoff Hydrographs
The specified duration of the unit hydrograph is called unit duration. A unit hydrograph for a particular unit duration may be utilized for evaluating the runoff hydrographs of other storms of like duration. This is because the shape of the unit hydrograph is assumed to be constant for a given basin.
Infinite Unit Hydrographs
The number of unit hydrographs for a given basin is theoretically infinite. This is because the shape of the unit hydrograph varies with the characteristics of the drainage basin, such as the slope, soil type, vegetation, and land use. Thus, a different unit hydrograph is required for each design storm.
Conclusion
In conclusion, all of the statements (a) to (d) are correct. The unit hydrograph and unit storm are important concepts in hydrology and are used for designing hydraulic structures and predicting runoff. The unit duration is the specified duration of the unit hydrograph, while the number of unit hydrographs is theoretically infinite.
