Surface Irrigation
Surface irrigation refers to a large group of irrigation methods in which water is distributed by gravity over the surface of the field. Water is typically introduced at the high point...

Simulating Evapotranspiration on Semi-Arid Rangelands
Detailed simulations of the surface energy balance using the Simultaneous Heat and Water (SHAW) model were compared with measurements collected at the Reynolds Creek Experimental Watershed...

Economic Issues Regarding Water Quality Objectives in the Grassland Basin
A conceptual framework is presented for evaluating the potential costs and benefits of water quality objectives in the Grassland Basin. The investments and expenditures required to achieve...

Adapting Water Resources of the Canadian Prairies under the impact of Climatic Warming
Given that future droughts could become more frequent and more severe because of climatic warming, this paper discusses some strategies to manage and to develop the water resources of...

Evaluating Soil Moisture and Hydraulic Conductivity in Semi-Arid Rangeland Soils
The United States Department of Energy's Office of Civilian Radioactive Waste Management (DOE-OCRWM) Fellowship Program supports various disciplines of academic research related to the...

Predicting Effects of Modifying Tussock Grassland
Measurements of rainfall, drainage, and weight change of a 6 m2 surface area cylindrical lysimeter containing nine snow tussocks (Chionochloa rigida)...

Use of Lysimeters to Measure Fog Interception in Tussock Grassland New Zealand
Previous studies of the water balance of single Tussock plants in small non-weighing lysimeters over a range of elevations in east-central Otago province suggest that tussock grassland...

Rangeland Evaluation of WEPP Hydrology
The hydrology component of the Water Erosion Prediction Project (WEPP) utilizes the W.H. Green and G.A. Ampt infiltration equation to simulate the rate and volume of excess rainfall. Excess...

Snow Fencing to Increase Streamflow on Rangelands
Snow deposition and water yield were increased 55% and 127% respectively, and duration of surface runoff was lengthened 17 days in response to snow fencing a sagebrush-covered watershed...

Application of RUSLE to Rangelands
The Universal Soil Loss Equation (USLE) has been revised to more accurately estimate soil loss from both crop and rangeland areas. Major revisions affecting rangeland soil loss estimates...

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...

Establishing Native Plant Communities on a Coastal Landfill, Berkeley, California
Three native coastal plant communities were successfully established in a park created on a landfill site on San Francisco Bay: coastal strand, coastal scrub, and prairie grassland. The...

Models of Border Irrigation for Flat Clayey Soils
Border irrigation is widely used for irrigating pastures in south-east Australia. Inadequate earthworks, design and operation of irrigation layouts have been major causes of waterlogging...

Engineering a Corporate Statement
Frito-Lay National Headquarters, Plano, Tex., occupies a 218 acre site in a corporate office park that had been a cow pasture. It was unusual in having mature trees and a natural watercourse...

Water Requirements for Range Plant Establishment
A conceptual model was developed which describes a series of pathways or transition sequences which a seed or seedling may follow during the initial wet-dry-wet periods after planting....

Cover Allocation in Rangeland Watershed Management (A Review)
The importance of cover on rangelands has been recognized for many years. This paper reviews the importance of cover in terms of infiltration and erosion and provides management recommendations...

Simulation of Natural Resource Systems
Desertification, defined as the loss in productive capacity of the land, has spawned research in decision making involving multi-objective situations. In this study, computer simulation...

Soil Movement and Surface Roughness on Wyoming Rangelands
Soil movement and surface roughness parameters were evaluated as a function of response to livestock grazing and semiarid shrub control treatments. Repeated elevation measurements of erosion...

Erosion, Productivity and Rangeland Watershed Planning
The Bureau of Land Management is responsible for the management of over 160 million acres of rangeland in the western United States. The principal uses of these rangelands are the grazing...

Streamflow Measurement and Analysis for Northwest Rangelands
Watershed hydrologic and sedimentation investigations on the Reynolds Creek Experimental Watershed in southwest Idaho were initiated in 1960. Major objectives of the watershed research...
