Runoff Modeling: Response time characteristics; Linear black box models for
continuous time systems – Time area methods, Unit hydrograph method; Linear
black box models for discrete time systems – UH derivation from multi storm
events; Non linear black box models; Linear conceptual models for continuous time
systems – Nash model, Clark model, Dooge model; Linear conceptual models for
discrete time systems – Discrete time linear reservoir, Discrete time Nash model;
Models for ungauged watersheds – Linear and non-linear conceptual models.
Hydrologic Abstractions: Interception – Empirical models; Depression storage;
Evaporation and evapotranspiration; Infiltration – Empirical models, conceptual
models, comparison and evaluation of infiltration models.
Hydrologic Inputs: Mean areal rainfall – Comparison of methods, accuracy
estimation; Geomorphology – Channel system, drainage basin system.
Watershed Yield: Water yield – monthly and yearly volumetric rainfall-runoff
models; Sediment yield – Process, empirical and conceptual models, routing
