Hydrologic Systems and Simulations

Preliminaries: Hydrologic investigation; Systems approach; Problems and models in

hydrology.

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

models.

Watershed Models: Event based simulation models  – Data needs, building of

simulation models; Continuous simulation models  – Elements, building of

continuous simulation models.

Application of Hydrologic Models: HEC-HMS, HEC-RAS, MIKE SHE, MIKE11,

MIKEFLOOD, ArcSWAT
