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...

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...

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...

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...

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...

Watershed Planning in Western Pennsylvania?A Case Study
This paper presents and describes the watershed planning activities being pursued in Allegheny County, Pennsylvania. The regulatory, institutional, and technical framework of the planning...

Comprehensive Watershed Management Planning?A Case Study - The Magothy River
As a means of preserving and improving the water resources of Anne Arundel County in the State of Maryland, the County government undertook a comprehensive watershed management program....

Land Management and Water Yield in the Appalachians
Watershed treatments on the Fernow Experimental Forest have included individual tree selection, commercial clearcutting, clearcutting upper and lower halves of watersheds, clearcutting...

Demonstration of Watershed Management Effectiveness in Sediment Control Using Comprehensive Watershed Modeling
The Arroyo Pasajero, which drains a 500-square mile watershed in the Coastal Range of California, flows into the San Joaquin Valley, intersecting the San Luis Canal section of the California...

Factors Affecting Neutron Gauge Calibration
Neutron gauge characteristics and soil chemistry affect gauge calibration. External factors also influence gauge calibration and should be considered in the calibration procedure. Gauge...

Rehabilitation and Modernization of Irrigation Projects is Often a Cover-up for Poor Quality Construction and Maintenance
Decreasing land and water resources available for irrigation projects is placing greater empasis on rehabilitation and modernization of irrigation projects. Inferior quality of the initial...

Understanding Delivery Performance Before Rehabilitation
In the initial stages of project formulation, decisions are made regarding the method for allocating water, and the method for physically distributing water. Any major rehabilitation effort...

Conjunctive Use of Surface and Groundwater
A computer model was developed by T. Sammis and Z. Samani to simulate the conjunctive use of surface and groundwater. The model consisted of a groundwater simulation subroutine and a crop...

Using Neutron Probes to Aid Irrigation Scheduling
Neutron soil moisture measurements are used to supplement irrigation forecasts on the 60,000 acre sprinkler-irrigated Navajo Indian Irrigation Project (NIIP). Weekly irrigation forecasts...
