Water Yield Responses to High and Low Spatial Resolution Climate Change Scenarios in the Missouri River Basin
Water yield responses to two climate change scenarios of different spatial scales were compared. Responses were determined by applying the Soil and Water Assessment Tool (SWAT) hydrologic...

Going Against the Grain
Conventional wisdom has it that granular soils perform better in mechanically stabilized earth (MSE) wall systems. Their properties are well known and simple to express in mathematical...

Raising the Bar of BART
Although it was originally designed to withstand a strong earthquake, and did so admirably in 1989, the Bay Area Transit (BART) system was recently evaluated to determine its ability to...

Integration of Watershed and Ecological Site Land Classification Scales Using GIS Technology
Advanced analysis of hydrologic processes for use in natural resource simulation models and related applications including rangeland health assessments can be facilitated by the integration...

Watersheds: Preparing Students for the Future
Colorado State University continues to maintain the only undergraduate major in Watershed Science since its inception over four decades ago. As the flagship of Watershed Science, CSU has...

The Watershed Modeling System
The Watershed Modeling System (WMS) is a comprehensive environment for hydrologic analysis developed by the Environmental Modeling Research Laboratory (EMRL) at Brigham Young University...

Stochastic Simulation of the Colorado River Flows Using SAMS
The main purpose of this presentation is to illustrate the applicability of SAMS to the Colorado River system. For this purpose we have utilized monthly data at 29 sites in the basin....

Probabilistic Simplified and Detailed Subsurface Drainage Water Quality Modeling of Nitrate Leaching
A transparent uncertainty structure is derived for simplified and detailed conceptual nitrate leaching as a result of a probabilistic modelling procedure. The uncertainty structure consists...

Stochastic and Deterministic Origins of Aquatic and Riparian Habitats
Development of aquatic and riparian habitats involves interactions among large numbers of climatic, geomorphic, hydrologic, and vegetative processes over time. A major component of these...

Investigation of Flood Protection from Alluvial Fan Flows and Minimizing Impacts to a Sensitive Habitat Preserve: Whitewater River Basin, Coachella Valley, California
The study describes and evaluates (1) the baseline conditions to hydrology, hydraulics, wind transport of sand, sediment transport by fluvial process, the environment, economics, and (2)...

Progress Report: ASCE Task Committee on State of the Practice in Curve Number Hydrology
In response to a growing awareness of the role of the Curve Number method in engineering and environmental impact applications, and its limitations, the Committee was formed in late 1997,...

Hydrogeology and Irrigated Agriculture
A review of drainage problems and groundwater processes on the west side of the San Joaquin Valley (SJV), California, provides useful perspectives on hydrogeology and irrigated agriculture....

Water Control Data System Modernization: Huntington District, Corps of Engineers
The Water Control Data System (WCDS) provides the tools that are used in making daily operational decisions for 35 reservoir projects and 9 navigation structures in Huntington District....

Spatial Decision Support System for River Basin Management
MODSIM is a generalized river basin network flow model designed to simultaneously assure that water resources are allocated according to physical, hydrogeological, and institutional/administrative...
