Higher-Order Methods for Transient Free-Surface Flows
One-dimensional transient free-surface flows in open channels are described by a set of quasi-linear hyperbolic partial differential equations, called the Saint-Venant equations. Numerical...
Predicting Ground-Water Drainage to Surface Mines
A two-dimensional, finite-difference numerical model is used to simulate the drainage of ground water into a surface coal mine. Graphs of dimensionless head as a function of dimensionless...
Hydraulics and Hydrology of Border Irrigation
Proper description of the hydraulics of irrigation of farmland is necessary in management. Many descriptions of furrow or border irrigation are not adequate to describe truly physically...
Thermal Breakup Predictions on a Regulated River
The thermal breakup process which occurs on the Peace River in Alberta, Canada is described. A quantitative technique which uses the energy budget to explain the celerity of the breakup...
Recreational Freshwater Embayment Design for Acceptable Water Quality
Combined field and laboratory studies were used to relate water quality, geometry, and exchange characteristics in reservoir swim embayments. Water surface fluctuations in reservoirs are...
Dual Source Water Supply Facilitates Power Plant Start-Up
The make-up cooling water supply for a four unit coal-fired steam turbine generating station required a peak demand of 28,000 gallons per minute (62. 4 cubic feet per second). Following...
A Cheap Solution to Pollution from Combined-Sewer Overflows
Every time it rains, the surface waters of many of the older communities around the U.S. are polluted by a mixture of sanitary waste and stormwater. The problem: when the community sewers...
The Place of Land Treatment of Wastewater in Today's Society
Land treatment of sewage can be a viable alternative to secondary and/or tertiary in-plant treatment. Depending on local conditions, overland-flow, low-rate, or high-rate systems, or a...
Newark Airport Pilots Cost-Saving Runway Paving Concept
The NYC Met Section nominee for the 1978 Outstanding Civil Engineering Achievement Award was the expansion of Newark International Airport. The $200 million redevelopment included a new...
Hydrographic Surveying Turns to Electronics
Traditional technique for measuring water depth is to use a lead-weighted line. The tag line, stretched along the water surface so soundings are made in orderly fashion, can be dangerous....
The Fight to Keep Houston From Sinking
Land subsidence has reached critical stages in several areas of the Houston-Galveston Bay region of the upper Texas Gulf Coast. Damages already incurred include the abandonment of a subdivision...
Let's Consider Land Treatment, Not Land Disposal
The regulations that control operation and design of land treatment systems are discussed. A solution to control ground water pollution must consider all potential impacts. Pretreatment,...
Porous Friction Course Solves Airport Hydroplaning Problem
Several hydroplaning incidents had occurred at the Greensboro-High Point-Winston Salem Regional Airport, N.C. Hydroplaning occurs when hydrostatic pressure builds up in the field of surface...
Proposed Standards: Land Disposal of Effluents
There are many alternatives to costly advanced waste treatment (AWT) systems. The most attractive of these is land disposal of the sewage effluents from secondary treatment plants. Land...
The Floating Cover: Best Way to Cover a Finished-Water Reservoir�
With the increased attention being given to drinking-water quality in recent years, many states have been pressuring towns and cities to cover their open, finished-water reservoirs. Years...
Contribution of Irrigation and Drainage to the World Food Supply
Proceedings of the Contribution of Irrigation and Drainage to the World Food Supply Specialty Conference held in Biloxi, Mississippi, August 14-16, 1974. Sponsored by the Irrigation and...
Automation of Irrigation and Drainage Systems
Proceedings of the National Irrigation and Drainage Specialty Conference held in Phoenix, Arizona, November 13-16, 1968. Sponsored by the American Society of Civil Engineers.
