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,...
Automated Estimation of Hydrologic Parameters
An expert system was developed that automatically generates drainage area boundaries and times of concentration using digital elevation and stream data. Drainage areas and hydrographs...
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...

Clark County, Nevada is currently implementing a Geographic Information System (GIS) to support County planning and engineering functions. The Regional Flood Control District is in the...
Flood Plain Management Integrating GIS and HEC-2
Little has been done over the years to either automate the more labour intensive activities involved in flood plain management or to increase the efficiency and accuracy of handling applications...
Low Stream Flow Frequency Analysis with Ordinary and Tobit Regression
In order to estimate the low-flow quantiles at ungaged sites, it is necessary to estimate low-flow quantiles at gaged sites. Two linear regression methods, denoted NR and NE, are compared...
Adaptive Parameter Estimation for Multisite Streamflow Forecasting
An adaptive procedure for parameter identification and noise statistics estimation for multisite streamflow forecasting is presented in this work. The model is a multivariate ARMAX model,...
Guidelines for Water Resource Models Development and Use
Water resources literature suggests that computer based models have the potential to provide useful information in facilitating water resources decision making process. Therefore, continuous...
