Agricultural Impacts on Surface Water via Ground Water
Three years of ground and surface water quality monitoring data collected from one site in the mid-Atlantic coastal plain are presented. These data suggest that delivery of P from ground...
Aldicarb Transport in the Coastal Plain of N. C.
The pesticide aldicarb is extremely soluble in water which causes it to be mobile in ground water. A field study was conducted to monitor the fate of the pesticide aldicarb in a poorly...
Water Quality Implications of Encapsulated Atrazine
This paper presents the movement of both encapsulated and wettable powder atrazine under no-till and conventional-till corn in the Coastal Plain physiographic region of Maryland. Soil...
Water Quantity and Quality for Irrigated Agriculture and Wetlands
A water balance for the Carson Division of the Newlands Project in Northwest Nevada was created to identify the potential recovery of irrigation drainage effluent from the shallow aquifer...
Recycling Wastewater by Drip Irrigation
Hawaii's sugar factories produce about 380 million liters of wastewater per day from sugarcane washing, condensation, and cooling operations. Since 1972, wastewater has been used to irrigate...
Expert System for Agricultural and Water Quality Management
Agricultural activities occur in an open environment where uncontrollable climatic events influence both agricultural productivity and water quality. A decision support system is described...
Management of Agricultural Drainage Pollution Considering Regional Cooperation
Increasing awareness of toxic substance discharge from agriculture in the San Joaquin Valley of California has resulted in discharge limits on individual constituents in agricultural drainage....
Gradual Development of Bores in Canal Systems
Modern computer programs for modeling unsteady flow in open channels are typically constructed using a momentum conserving form of the Saint Venant equations. This allows computation of...
Design of Irrigation Distribution System
This paper briefly discusses the Bureau of Reclamation's process of developing the rehabilitation of the Grand Valley Unit in Colorado. Sections are included on accessing needs of the...
Prediction of Sedimentgraph from a Small Watershed in Poland in a Changing Environment
Estimates of sedimentgraphs and temporal distributions of sediment concentrations are essential for prediction of pollutant concentrations in streams and reservoirs. In such predictions,...
Linking GIS with Hydrologic Modeling
A GIS-based methodology for conducting rapid assessments of pesticide and nutrient transport within agricultural watersheds was recently developed. This methodology is based upon the use...
Engineering Answers to Groundwater Impact Questions Using a Geographic Information System (GIS)
Environmental concerns have raised complex questions about the impacts of increased groundwater levels adjacent to navigational pools along the Red River, Louisiana. Previous studies had...
Seven Legal Strategies to Cool Global Warming
The author holds that there are seven types of legal approaches which can be employed by different levels of government to cool global warming. Application of these strategies, singly...
Climate Change and Water Management Flexibility
Changes in regional climate expected to occur as a result of the accumulation of greenhouse gases may have significant impacts on water resources. In this paper, I examine the sensitivity...
Importance of the Tropical Rainfall Measuring Mission (TRMM) Satellite to Hydrological Investigations
Rainfall over the global tropics is crucial to the global hydrological cycle and to water resources in most developing countries. Its magnitude and variations are presently poorly known....
Applications of Remote Sensing to Hydrology
This paper pulls together examples of current applications of remote sensing information to hydrology. Topics covered include rainfall, snow hydrology, soil moisture, evapotranspiration,...
Applications of Remote Sensing to Irrigated Agriculture
Several uses for satellite digital imagery and data from portable field radiometers have been developed for the monitoring of agricultural crops, their yields, insect and disease attacks,...
Applications of Remote Sensing to Drainage
This paper summarizes examples of current applications of remote sensing information to drainage. Topics covered include drainage basin parameters, drainage problem identification, salinity...
Targeting of AgI in a Utah Winter Orographic Storm
A cooperative research program among the Utah Division of Water Resources, the National Oceanic and Atmospheric Administration, and the Bureau of Reclamation has investigated targeting...
Results from a Long-Term Winter Cloud Seeding Program in Utah
An operational wintertime cloud seeding program has been conducted in portions of Utah since 1974. North American Weather Consultants (NAWC) has conducted this program for a consortium...
