Rating Systems to Evaluate Onfarm Water Conservation
The U. S. Department of Agriculture, Soil Conservation Service, concentrates its assistance on modernization of onfarm irrigation systems and improvement of water management to provide...
Irrigation Scheduling with the Neutron Probe
In 1981, the Imperial Irrigation District in cooperation with the United States Bureau of Reclamation started a demonstration irrigation scheduling program on 15,000 acres (6,075 ha)....
Effect of Subsurface Drainage in the Lower Mississippi Valley on Surface Water Quality
Sediment and nutrient losses were measured from a subsurface drainage-runoff-erosion experiment for the years 1981 to 1984. The experiment, located near Baton Rouge, Louisiana, consisted...
Effect of Agricultural Drainage on Surface Water Quality in Delaware
Parts of Kent and Sussex counties, Delaware, require drainage to have productive agricultural soils. Drainage has been installed on the Delmarva Peninsula since colonial days. Drainage...
Irrigation Water Requirements Under Wide-Spaced Furrow Irrigation
Research has shown that wide-spaced furrow irrigation (WSFI) can produce acceptable yields of crops with less water than every-furrow irrigation (EFI). In many seasons WSFI will result...
A Practical Means for Estimating Irrigation Canal Seepage Contribution to Agricultural Subsurface Drains
This paper describes a means for estimating canal seepage contribution to nearby agricultural subsurface drains. Canal seepage rate is influenced by a complex of many variables, but the...
Streamflow Losses, Consequent Flow Through a Thick Unsaturated Zone, and Recharge to an Unconfined Aquifer
Two experiments were conducted in conjunction with a 23-day aquifer test made in south-central Arizona to determine (1) water loss from a natural channel and (2) flow through a 330-foot-thick...
Daily Weather Forecasts Used to Manage Soil-Water
This paper describes a newly developed method for analyzing the rainfall probability data included in daily weather forecasts issued by the National Weather Service. The purpose is to...
Oil Spill Detection by NOAA/AVHRR on Persian Gulf
An area of oil spills on the Persian Gulf was detected by the thermal-infrared channels of Advanced Very High Resolution Radiometer (AVHRR) on NOAA-7. AVHRR gives the temperatures of the...
Report: Persian Gulf Conference, May, '84
The First International Conference on the Impact of Oil Spill in the Persian Gulf was held at the University of Tehran, Islamic Republic of Iran (I. R. I. ), from 20 May to 27 May, 1984....
Sand Rights A Legal System to Protect The Shores of the Beach
The legal system of water rights in California is highly developed. So far, however, it has failed to recognize in any comprehensive fashion the importance of the sand which is transported...
Examples of Sediment Distribution in the Italian Adriatic Coast. A Comparison Between the Shepard and the Nota Textural Classifications
Four sectors of the western Adriatic coast, each with a different feature, represent the test areas to evidence the differences between the two textural classifications of sediments by...
Managing the Dunes and Wetlands of Norfolk, Va.
The Code of the City of Norfolk was amended in 1982 to establish a procedure for permitting and preservation of the city's saltmarshes and sand dunes. A Wetlands Board was...
Regulatory Reform in Alaska: An Oil Industry Perspective
The State of Alaska recently implemented regulatory reform procedures to streamline the permitting process and ease the regulatory burden on the regulated community, as well as the burden...
Sand for Beach Nourishment in Lower Chesapeake Bay
The Virginia Institute of Marine Science designed and performed an inventory of the resources of sand in the southernmost portion of Chesapeake Bay. The primary purpose of the project...
The Bowhead Whale and Offshore Petroleum Operations in the Arctic
Eskimos, environmentalist groups, and government agencies have stated their concerns about possible effects on the bowhead from offshore petroleum operations. These concerns fall into...
A New Method for Effective Beach-Fill Design
Beach nourishment with sand fill has been extensively used to restore recessional beaches, but the success of this method has been variable due to a poor understanding of sediment dispersion...
Stabilization of Dunes with Flexible Mattresses
Dunes, constantly moving due to influences of sea and wind, are inherently unstable and in many, if not most situations, are best left in their natural state of change. Where there is...
Some Econological Observations on Coastal Plant Communities, of New York and New Jersey
The present study was conducted at three coastal sites, Fire Island, New York, Fort Tilden, New York, and Sandy Hook, New Jersey. Four plant communities, the salt marsh community, sand...
Man-Made Offshore Islands: An Innovative Solution to Coastal Erosion
Existing shore-parallel detached breakwaters have resulted in the accretion of sand along the shoreline in the wave shadow of the structure. Significant prograding of the beach has replaced...
