Modeling of Rattlesnake Creek Watershed Using Swat Model
Watershed scale models are widely used in design and operation of river basin projects and for guiding public decisions. This paper presents modeling details of Rattlesnake Creek watershed...

Assessment and Implications of Local Channel Instability on the Prediction of Bridge Scour
Current assessments of the potential for scour at existing and new bridges do not include the effects of local channel instability on predicted bridge scour estimates. Local channel instability...

Use of Geomorphic Data for Assessing Stream Stability at Bridge Structures
The authors recently completed a statewide bridge scour evaluation for the Nevada Department of Transportation, which included evaluation of the geomorphic processes of bank erosion and...

Urbanization and Hydrologic Consequences in Simi Valley, California
Regressional analysis of historical hydrological data including rainfall and runoff data reveal that although there has not been a significant temporal change in the amount of rainfall...

SAMS: Software for Simulating Streamflow Series
This paper introduces SAMS, a computer software developed for the analysis, modeling, and generation of hydrologic time series such as annual and monthly streamfiows. It is written in...

Flood Damage Estimates Using GIS Spatial Analysis
The catastrophic flooding in the midwest during the Summer of 1993 and in California in the Spring of 1995 resulted in flood damage estimates in the hundreds of millions to billions of...

Preliminary Validation of the MAC3D Numerical Flow Model
MAC3D is a recently developed numerical model for three-dimensional incompressible flow. Model predictions are compared with physical test data for a curved open channel and a multi-level...

A Finite Element Analysis of Mach Reflection by Using the Boussinesq Equation
The numerical analysis of Mach reflection, which is the reflection of an obliquely incident solitary wave by a vertical wail, is presented in this paper. For the mathematical model in...

3D Flow Structures?From Laboratory to Field Applications
One laboratory experiment and one field application have been modeled. For each one different sources of errors in the model results could be detected. It may be concluded that the applicability...

Verification of a 3D Flow Model Using Laboratory Data
The ASCE Task Sub-Committee on 3D Free Surface Flow Model Veri fications has been developing test cases and/or procedures for both computational model developers and users over the past...

County-Wide Drainage Study Using GIS
A county-wide drainage study was conducted for the County of San Joaquin, California, Department of Public Works, for the determination of storm runoff quantities for the planning of flood...

GIS Applications in Modern Stormwater Management
A Geographic Information System (GIS) is a technology that aids stormwater management through efficient data manipulation, analyses, and graphic displays. The integration of GIS with stormwater...

A Hydrodynamic FVM Algorithm on Arbitrary Grids
This paper presents a finite volume algorithm for the vertically averaged integral form of the hydrodynamic governing equations on an unstructured grid system. The algorithm is applicable...

Estimation of High Spring Floods Causing Inundation in Non-Studied Rivers of the West Siberian Plain
Spring flooding is the main and the most abounding in water period in flow regime of West Siberian rivers. As a result, there is powerful and wide inundation on relief of West Siberia....

Numerical Simulation of Bridge Abutment Scour Development
This paper reports a project to simulate the development of a local scour hole around a bridge abutment by a computational model. From the prelim inary results obtained, it may be concluded...

The Use of an Equivalent Porosity Method to Model Flow in Marshes
Two dimensional modeling of marshes under unsteady flow conditions often involves description of sections that alternately wet and dry. The equivalent porosity method (King and Roig, 1988;...

Direct Measurement of Turbulence Structures in a Standard Jar Test Tank Using PIV System
Particle image velocimetry (PIV) is applied to the measurement of instantaneous two-dimensional velocity fields in a standard 2-liter jar test tank for several different impeller speeds....

Data Analysis for Computer Modeling of Thermal Discharges
Assessment of the thermal discharge impact upon the environment and design of the appropriate discharge structure necessitate a range of data activities, from extensive field measurements,...

The HEC NexGen Software Development Project
The NexGen project is developing successor software packages to the existing family of HEC computer programs. Development is occurring via teams comprised of technical specialists, computer...

HEC-RAS (River Analysis System)
HEC-RAS (River Analysis System) is an integrated system of software, designed for interactive use in a multi-tasking environment. The system is comprised of a graphical user interface...
