Evaluation of Electronic Temperature/Relative Humidity Sensors
Temperature and relative humidity measurements are routine parameters required for most agricultural meteorological applications. Reliable measurements of relative humidity, especially...

The Utah Climate Center Weather Data Network
The Utah Climate Center weather data network includes 52 sophisticated, automated weather stations. Weather parameters are monitored in real-time and hourly summarized data are gathered,...

Streamflow Depletions and Water Transfers in Idaho
In the state of Idaho, streamflow depletions are quantified utilizing parameters of rate of flow, total volume diverted, and volume consumptively used. This paper summarizes the engineering...

Streamflow Depletions Considered in Water Transfers
In the State of Colorado, streamflow depletions are defined as that amount of water diverted to beneficial use minus return flows to the stream system. This paper summarizes the engineering...

Evaluating the Facts in Water Right Changes
Under the western system of appropriation water rights may be separated from the land and the time, type and place of use changed. Such changes are governed by the principle that there...

Soil Moisture Monitoring Using a Portable Capacitance Probe
Accurate monitoring of soil moisture has long been in integral part of a successful agricultural management system. Water has increasingly become a valuable and much sought after natural...

Availability Analysis of Irrigation Systems for Improved Management
Availability of an irrigation system is defined as the ratio of time of successful system operation to total desired operation time. Operation is successful when the flow rate of water...

Evapotranspiration of Dry Beans with Drip Irrigation
Information about the effect of irrigation on dry bean production in the Southwestern Colorado is very limited. The primary objective of this study is to establish a crop water use (ET)...

Computing in Civil and Building Engineering
This proceeding consists of papers presented at the Fifth International Conference on Computing in Civil and Building Engineering held in Anaheim, California, June 7-9, 1993. The proceedings...

A Solid Waste Solution
Burgeoning growth and diminishing landfill capacity have been propelling Broward County, Fla. toward a solid-waste crisis. The county, located along Florida's southeastern...

Pioneer Highway
The 1993 Outstanding Civil Engineering Achievement Award goes to the $490 million I-70 Glenwood Canyon in Colorado. The final link in Interstate 70 from Baltimore, Md. to Cove Fort, Utah,...

Simulation of Buoyant, Miscible Liquid Plumes in Heterogeneous Aquifers
Laboratory experiments have been conducted in a sand tank with a single heterogeneity into which NaNO3 is continuously injected. From samples along, across and over the depth of the tank...

Adaptive Control of Unavoidable Hazardous Releases
This paper presents a procedure for the adaptive control of hazardous releases of toxic substances. In particular, the control strategy is aimed at deliberate releases from man-made storage...

Optimization Modeling for Sedimentation in Alluvial Rivers Considering Uncertainties
A nonlinear optimization model is formulated for determining optimal reservoir releases to minimize channel bed aggradation and degradation in downstream rivers. The model is based upon...

Refined Modelling of Water Quality Constituents in a Semi-Enclosed Coastal Wetland Basin
Details are given of the refinements to a numerical model to improve the representation of the advective transport of water quality constituents. The higher order accurate scheme adopted...

Engineering Geomorphology
Engineering geomorphology is the application of geologic and geomorphic principles to the solution of river engineering problems. Development of a process-based understanding of a problem...

Multi-Disciplinary Strategies for Flood-Plain Restoration at the River Rhine
Within the scope of a multi-disciplinary concept, aims and measures of ecological and water resources management at the river Rhine in Nordrhein-Westfalen (Germany) are analyzed. Especially,...

Development Strategies for Botswana's Okavango Delta
This paper contrasts two different development strategies for the Okavango Delta - the Government of Botswana's Southern Okavango Integrated Water Development Project and an IUCN-proposed...
