An Integrated GIS and Model for Assisting the Managers of an Army Training Area
The ARC/INFO geographic information system (GIS) has been combined with the ARX spatial expert system and the SMSP soil moisture-soil strength model to assist the managers of a major training...
Environmental Compliance and River Maintenance on Santo Domingo Pueblo, New Mexico
River maintenance activities within the boundaries of the Santo Domingo Pueblo on the Rio Grande have departed from the traditional channelization philosophy and employed engineering methodologies...
Effects of Water Erosion Processes on Drainage and Irrigation Systems
This study examines the relationship between geomorphic processes and drainage/irrigation projects. It illustrates the method of geomorphic analysis by the study of a drainage project...
Morphology and Roughness in the Hydraulics of Large Bed Element Channels
The evolution of natural steep channels is a function of two factors in accordance with the principle of least action: flow distribution in the channel and terrain geomorphology. Large...
A Comparison of Runoff and Sediment Yields from Bare and Vegetated Plots Using Rainfall Simulation
Data from 108 small plot rainfall simulator experiments on pinyon-juniper woodlands in Arizona and New Mexico were analyzed to determine quantifiable effects of cover on hydrologic and...
Effects of Surface Drainage on Sediment Yield in Southern Delaware
Sediment surveys were conducted over a period of 16 years on two small reservoirs in the Nanticoke River basin, Delware in order to assess the effects of watershed drainage projects on...
Sediment Production from Forest Roads with Wheel Ruts
Artificial rainfall was applied to two sets of paired plots 30.5 m long by 1.52 m wide, each set on a different soil type. One plot in each set contained a wheel rut while the other did...
Effects of Forest Cover on a Snowpack in the Sierra Nevada
Adjacent snowpacks in a clearing and under a forest canopy were compared over a decade at a site near Lake Tahoe. This comparison provides a few indications of the differences in snowpack...
An Interactive Computer Model to Simulate Water Quality of Streamflow from Forested Watersheds in Arizona
To better formulate water resources policies and management strategies, a computer model that simulates concentrations of dissolved chemicals in snowmelt-runoff from forested watersheds...
Hydrologic Effects of Brush to Grass Conversion
A physically based rainfall-runoff model is used to detect hydrologic response to artifically induced vegetation changes on a semiarid watershed. Model parameters are optimized using a...
Watershed Hydrograph Simulation Through Dendritic Channel Networks
In this paper, a linear dendritic simulation model based on the finite difference implicit scheme is presented. In this model, a dendritic matrix solution algorithm for simultaneous solution...
Management Strategies for Baseflow Augmentation
Management strategies for baseflow augmentation fall into the following categories: (1) range management, (2) upland vegetation management, (3) riparian vegetation management, (4) upland...
Precipitation Variability Effects on Modeled Soil Water Deficits
Effective management of forages in steep Appalachian pastures requires an understanding of hydrologic and microclimatic processes on the area. This study was conducted to determine the...
Soil Moisture Measurements in Oil Shale Waste Material Using a Neutron Probe and Time Domain Reflectometry
Five large scale lysimeters (7.3 ? 3.0 ? 3.0 m deep) have been constructed to collect information and data on hydrological factors which affect the movement of water through a large scale...
Predicting Overland Flow Response: Effects of Spatially-Varying Soil Properties
A physically-based model of Horton overland flow is applied to experimental data from a simulated rainfall event in eastern Washington. The model employs the Green-Ampt infiltration equation...
Development and Implementation of the Wekiva River Basin Regulatory Program in Central Florida
The St. Johns River Water Management District developed a comprehensive surface water management program for the basin. Between 1987 and 1989 the District implemented basin specific design...
Procedures Used for Determining Water Rights on the Caribbean National Forest
In response to increasing demand, the Commonwealth of Puerto Rico enacted legislation requiring current users of water to file existing water uses. Application for water rights on the...
Management of Groundwater Overdraft in the Phoenix, Arizona, Area
By law, the overdrafting of groundwater in the Phoenix, Arizona, area must cease by the year 2025. Safe yield can be achieved by means of conservation, water supply augmentation, and condemnation...
Water Use by Naturally Occurring Vegetation
A new publication is available to aid the practicing hydrologist or engineer in estimating the water use of naturally occurring plants. It serves as a general introduction to the subject...
Summary Report: Evaluation Criteria for Watershed Models
After an extensive literature review, the Task Committee recommends that, in addition to graphical plots, modelers use three simple goodness-of-fit criteria for evaluating continuous hydrograph...
