  1. HydrologyRainfall - Runoff Modeling (III)Conceptual Instantaneous Unit Hydrograph Prof. Ke-Sheng Cheng Department of Bioenvironmental Systems Engineering National Taiwan University

  2. Synthetic unit hydrographs • For areas where rainfall and runoff data are not available, unit hydrograph can be developed based on physical basin characteristics. • SCS unit hydrograph • Clark’s IUH (time-area method) • Linear reservoir model (Nash model)

  3. Nash’s linear reservoir model • Consider a linear reservoir which has the following characteristics:

  4. Summary of the Conceptual IUH modelAssumption: Linear Reservoir S(t)=kQ(t)
