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...

Simulation of Catchment Response Using RC Network
This paper describes a simple physically-based distributed parameter hydrologic model of catchment response using a network of capacitors and resistors. The effect of topography is modeled...

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...

Impacts of Climate Change in the Missouri River Basin
The Soil and Water Assessment Tool (SWAT) is being used as a base model to simulate the Missouri River basin for prediction of the impacts of climate change on water resources in the region....

The Caspian Sea Transgression (Environmental Medical Aspect)
From 1978 until 1994 the level of the Caspian Sea has risen by 220 cm, in 1994 by 30 cm. The study of environmental medical situa tion in the Russian zone of the sea transgression impact...

Simulation of Dissolved Oxygen in Sacramento-San Joaquin Delta
A one-dimensional model has been developed to simulate water quality in a complex multi-channel estuarine system. The model utilizes a Lagrangian reference frame for transport computations....

Simulation of Pesticide Transport for Verification of the DWRDSM
The California Department of Water Resources Delta Simulation Model (DWRDSM) is periodically verified against new hydrodynamics and water quality field data to ensure reliability and identify...

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...

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....

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...

Hydrologic Modeling System
The Hydrologic Modeling System (HEC-HMS) is new-generation software for precipitation-runoff simulation that will supersede the Hydrologic Engineering Centefs HEC-l program. Technical...

Next Generation Flood Damage Analysis Program
The Hydrologic Engineering Center has developed a next generation Flood Damage Analysis computer program for formulating and evaluating flood damage reduction plans. The program design...

A Combined Physical and Mathematical Modeling Scheme for Kapichira Hydropower Project, Malawi
A physical model and a mathematical model were used to study the flow patterns in a reservoir having a complicated bathymetry. The physical model measurements were compared with the predictions...

Karst Water Inventories Using Thermography
An airborne thermal camera was used to locate springs, swallets, and caves in a karst watershed. The detector was an imaging infrared camera with a temperature sensitivity of approximately...

The Use of Hydrologic Budget Techniques in Assessing Site Suitability for Wetland Creation
This paper discusses the general concepts and benefits of using of hydrologic budget techniques to describe the typical hydrologic conditions that might be expected at prospective site...

Los Angeles County Department of Public Works Storm Water Quality Assessments, Los Angeles, California
This study included a general assessment of the surface water quality conditions within the Los Angeles County area by examination of the surface water quality data collected by LACDPW...
