Uncertainty in Unsaturated Zone Pollutant Transport
The portion of a pollutant spill transported to an underlying aquifer is uncertain due to the stochastic nature of precipitation and uncertainty in the geochemical properties of the contaminant...

Cultivation of Christmas Trees Using Reclaimed Municipal Wastewater
This investigation was initiated to identify benefits and limitations associated with application of reclaimed domestic wastewater to a crop of improved Virginia pine christmas trees....

Innovations in Army Treatment of Remote Site Wastes
The U. S. Army Construction Engineering Research Laboratory (USA-CERL) is currently evaluating new methods for waste treatment at remote sites which will eliminate or mitigate problems...

Health Hazard Assessment of Waterless Remote Site Waste Management Technologies
The United States Army Construction Engineering Research Laboratory (USA-CERL) has had an ongoing research program addressing remote site waste treatment technologies. The potential for...

Adsorption and Release of Heavy Metals in Contaminated Soil
This study investigated the adsorption and release rates of toxic metals in soil type associated with hazardous waste sites common to the Northeastern United States. Five heavy metals...

On-Site Containment of PCB-Contaminated Soils
A remedial investigation/design project, with subsequent post-closure monitoring, was conducted for upland areas containing PCBs at an industrial site in New Bedford, Massachusetts. A...

Foundations in Permafrost and Seasonal Frost
The papers in this volume cover the following subject areas: A method that utilizes a decision matrix diagram for selecting the most suitable and economical foundations for construction...

Issues in Dam Grouting
Although perhaps the largest number of individual grouting projects do not involve dams, by far the largest volume of grout used is for grouting of new or existing dams. This volume presents...

Dewatering--Avoiding Its Unwanted Side Effects
The undesirable side effects that sometimes occur when dewatering for construction or mining are presented, including: ground settlement due to dewatering; deterioration of timber piling;...

Irrigation Canal Seepage and its Measurement
Reduction in seepage is one of the primary reasons used to justify investment in canal lining. Such justification depends greatly upon estimates of seepage through surface and subsurface...

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...

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...
