Grouting Against Hazwaste
Grouting has only recently entered the hazardous-waste arena, mainly in the form of positive cutoff slurry walls. At an industrial landfill near Niagara Falls, N.Y., a three sided, single-line...

Environmental Impacts of Agricultural Drainage
Research has shown that improved drainage increases peak runoff rates and pollutant loads compared to natural conditions. However improved drainage on agricultural lands may reduce outflow...

Engineering of Controlled-Drainage Systems
Soil-water management by water table control (via a dual purpose subdrainage-subirrigation system) is becoming popular in humid regions of the U.S. and Canada. Controlled-drainage is an...

Optimizing Economic Returns in Drainage Design
Soil wetness is a limitation to high agricultural productivity in Northern New York (NNY) where some 325,000 ha of cropland require drainage treatment. Drainage is needed for trafficability...

Stabilizing Drop Structure by Drainage Modifications
East Drain Terminal Drop Structure is located in East Drain, an open toe drain of Palmetto Bend Dam, in the tide water area of south Texas. The drop structure was threatened by piping...

Tapping Shallow Groundwater with Horizontal Wells
In recent years, horizontal wells have become an economical water supply source alternative for many shallow water table areas in Florida. Horizontal wells typically utilize 15 to 20 cm...

Agricultural Drains and Safety of Dams
Bonny Dam is located in east central Colorado on the South Fork Republican River. The dam's foundation is in the relatively porous Ogallala formation. Throughout the history of the dam,...

Design of Transient and Steady State Drain Spacing
Drain spacings calculated by steady state or transient equations can be made equal by adjusting the design water table height used in the equations. The adjustments are not constant and...

Wellfield Protection Program in Broward County, Florida
The Potable Water Wellfield Protection Program was initiated early in 1981. It examined land uses in the County, made an inventory of potential ground water pollution sources, compiled...

Case Study: Design of Groundwater Quality Monitoring Systems
This paper demonstrates the fundamental aspects of the design an implementation of state-of-the-art groundwater monitoring system, using conventional design principles. Based on experiences...

Use of D-C Resistivity to Map Saline Ground Water
It has been estimated in previous studies that 23 square miles of the Oxnard aquifer, a member of a multi-layered aquifer system beneath the Oxnard plain in Ventura County, California,...

Statistical Decision Analysis for Interception Wells
In this paper we apply the Bayesian decision analysis to the engineering design of a groundwater interception well whose purpose is to capture a contaminant plume. Two decision variables...

?H and ?⁴C as Tracers of Ground-Water Recharge
Surface spreading of water from the Santa Clara River is used to recharge aquifers underlying the Oxnard Plain. These aquifers are divided into an upper system about 400 feet thick, and...

Water Quality Effects on Eucalyptus ET
The researchers are testing established methods for measuring evapotranspiration (ET) from a 6-year old plantation of Eucalyptus camaldulensis containing about 3,000 trees per ha in a...

Influence of Irrigation on Subsurface Drainage
The influence flood irrigation has on drainage effluent in terms of discharge rates and water quality was analyzed at an artificially drained alfalfa field in Fallon, Nevada. Immediately...

Holistic Approach to Irrigation Management in Developing Countries
Sound development of irrigation and drainage projects in developing countries is a continuing need to reduce hunger, environmental degradation and excess population growth; and to promote...

Ecuador?The Lower Guayas Flood Control and Drainage Project?A Case Study
The Government of Ecuador (GOE) invited the World Bank in 1975 for a general review of the rural development in the country. One of the main findings of a Bank mission was the importance...

Rehabilitating Irrigation Systems from the 20th Century for the 21st Century
Irrigation projects were begun in the southwestern United States in the late 1800's. These projects were increased and modified during the 1900's and have become the lifeblood of reservations...

Irrigation and Drainage System As-Built Map Preparation Using Satellite Digital Imagery and a GIS
Multispectral remote sensing from satellite platforms has led to the development of numerous applications which use digital imagery for the classification and mapping of natural resources...

Role of Land Information System in Operation and Maintenance of Irrigation Systems Bureau of Reclamation
The Bureau of Reclamation manages more than 8 million acres of land in the 17 Western States and is required to periodically report on the status of the lands under its jurisdiction. A...
