Runoff Modeling Using the Geomorphological Instantaneous Unit Hydrograph and ARC/INFO Geographic Information System
The degree to which the spatial variability of watershed characteristics (geographical and climatological) is recognized for simulating watershed runoff depends on the hydrologic model...

Application of a Geographic Information System to Hydrologic Modeling Using HEC-1
A geographic information system (GIS) was used to derive areally-weighted hydrologic parameters for input to the HEC-1 hydrologic model for approximately 600 square miles of Pierce County,...

A GIS Based Geomorphic Approach for the Digital Computation of Time-Area Curves
Hydrologists routinely operate simulation models to approximate the runoff process. A popular strategy is the routing of a 'time-area' histogram. In addition, state-of-the-art hydrologic...

A Perfect Base for a GIS: The Digital Orthophoto
A digital orthophoto is a rectified image with no relief displacement or radial distortion inherent in an aerial photo. One advantage of a digital orthophotography is that it can be used...

Real Time Forecasting at a Major Flood Control Project
Using data from a network of real time rain and stream gages, Alabama Power computes inflows in a deterministic streamflow model and adjusts outflows hourly to achieve optimum flood control...

Prediction of Runoff-Evapotranspiration to Estimate Leachate Generation in a Landfill
The fraction of precipitation that remains after runoff and surface water evaporation, enters into the solid waste landfill and generates leachate flow at the bottom. A part of the infiltration...
