Unsteady Flow in a Navigation Channel
Based on the de St Venant equations, the Preissmann's implicit finite difference scheme, and the double sweep algorithm, a mathematical model for one-dimensional unsteady...
Entropy as a Probability Concept in Energy-Gradient Distribution
The concept of entropy based on probability theory instead of thermodynamic principle has been applied to study the distribution of energy gradient along alluvial rivers. The formulas...
Longitudinal Dispersion in Rivers: A Dead Zone Model Solution
The longitudinal dispersion of tracer material in rivers is often analyzed based on the one-dimensional convective diffusion equation developed by G.I. Taylor. However, the persistent...
Discharge Measurement by Thermal Dilution
A flume study was conducted to develop and improve the thermal dilution method of discharge measurement in trapezodial channels. The study was performed in an indoor channel with dischages...
Silt Run Effectiveness in Withdrawing Sediment
An investigation was conducted during the silt runs on the North Platte River to determine the continued effectiveness of the runs in providing fine sediments to the canal systems downstream....
Utilization of Ground Penetrating Radar to Conduct Sediment Surveys of Frozen Reservoirs
The ground penetrating radar (GPR) system consisted of a control unit, antenna, recorder, a power supply on a sled towed by a snowmobile. A 120 Mhz antenna was utilized and gave excellent...
Sediment Flushing Experiences at Cherry Creek Dam
An overview of the U.S. Army Corps of Engineers, Omaha District's experiences in sediment flushing operations at Cherry Creek Reservoir near Denver, Colorado is presented....
An Error Analysis of the Dynamic Wave Model
The Dynamic Wave Operational Model (DWOPER) is used to forecast river stages on the Lower Columbia River. DWOPER was developed by the National Weather Service's Hydrologic...
Computer Aided Hydraulic Design of Open Channels
The results of tests by the U.S. Army Corps of Engineers District, Los Angeles (LAD), became a major part of the Corps' EM 1110-2-1601, Hydraulic Design of Flood Control Channels....
Debris-Flow Research and Engineering Practice
For debris-flow analysis to enter standard engineering practice, future research must extend existing models to deal with major complications that arise in field practice. This paper reviews...
Two-Dimensional River Modeling of Buckhorn Creek
A two-dimensional Finite Element Surface Water Modeling System (FESWMS-2DH) was used to simulate flow at a bridge crossing of a heavily vegetated flood plain where State Highway 130 crosses...
Waste Processing: Makes Good Energy
Materials separation in solid wastes streams will generate more BTU's at waste-to-energy facilities. The removal of noncombustibles like bottles, batteries and refrigerators...
Hydraulic Engineering
The papers in this book were presented at the National Conference on Hydraulic Engineering, August, 1988, Colorado Springs, Colorado. The objective of this conference was to provide a...
Minipiles Mature in America
After being born more than 40 years ago in Europe, minipiles are maturing in the United States. Their distinctive feature is a relatively small diameter, rarely larger than 12 in. Constructing...
Out of the Mainstream
By treating only part of the wastewater stream, a biological/chemical phosphorus removal system also reduces chemical costs and sludge production. The system consists of two 60 ft dia...
Water-Quality Ponds ? Are They the Answer?
Water-quality 'wet' ponds have been proposed to treat storm water for the removal of phosphorous in streams tributary to Cherry Creek Reservoir, a major recreational...
Quality Changes of River Rhine and Meuse Water Upon Basin Recharge in the Netherlands' Coastal Dunes: 30 Years of Experience
A wide spectrum of quality changes of river Rhine and Meuse water is presented, on a global scale after pre-treatment, dune infiltration and post-treatment. Attention is focussed on the...
Augmenting Water Supply in the Phoenix Area Through Recharge of Surplus Central Arizona Project Water Into the Agua Fria Riverbed
This paper describes the efforts of several months activities in the initial stages of developing a 30,000 feet Demonstration Recharge Facility for surplus Colorado River water on the...
Granite Reef Underground Storage and Recovery Project
The Granite Reef Underground Storage and Recovery Project facility is an integral part of the largest water management system under development for the Phoenix metropolitan area. The project...
Artificial Ground Water Recharge in Southern California
