Distributed Hydrologic Models for Flow Forecasts - Part 1 (1.0-1.5 hr)

This module provides a basic description of distributed hydrologic models and how they work. It begins with a review of hydrologic models, and then examines the differences between lumped and distributed models. It explains how lumped models may be distributed by subdividing the basin and suggests when distributed hydrologic models are most appropriate. Other topics covered include the advantages of physically-based versus conceptual approaches and some strengths and challenges associated with distributed modeling.
