Land application of sewage sludge in agricultural land in Nigeria with special reference to Enugu.
(1982)
Comparison of the costs of producing some Nigerian agricultural crops by using sewage sludge and commercial fertilizer showed that sewage sludge is 14 and 33 times less expensive than commercial fertilizer using sludge ...
Phosphorus chemistry under aerobic and anaerobic conditions in model two-celled waste stabilization ponds.
(1980)
This study involved a laboratory examination of the phosphorus interactions between the sediment and water as they occur on a diurnal basis in a waste stabilization pond under summer conditions in the southcentral U.S. At ...
Municipal, irrigational and industrial future water requirements in Saudi Arabia.
(1982)
The future water requirements were matched against the available water resources, and it was found that the limited ground water reserves must play a major role in order to meet the future water requirements. To reduce ...
Heuristic statistical models for carbon monoxide in El Paso, Texas.
(1982)
On the basis of existing data it was determined that while traffic is the major source of CO in the area, meteorological factors provide the dominant influence in the elevation of these concentrations to levels that exceed ...
The mathematical macroscopic optimization procedures for transportation safety resource allocation in local urban jurisdictions.
(1982)
Two mathematical programming models, named the Feasibility Assessment Technique and the Optimality Assessment procedure, are developed in this dissertation to select, analyze and allocate safety countermeasures that result ...
Utilization, planning, and problem evaluations of urban arterial waterways and corridors as an urban resource.
(1981)
Widespread concern about flooding and possible use of the nation's urban river corridors has generated unprecedented interest in the potential for utilization of urban riverine corridors while simultaneously protecting the ...
The development of aquatic ecoregions in Oklahoma /
(1984)
This study was to determine if a technique could be developed for assigning aquatic ecoregions to streams in Oklahoma. It was determined that watershed attributes, generally available on a statewide basis, can be used to ...
Research to establish ecological standards for water resources developments.
(1981)
Three levels of development were identified to represent the environmental condition of the region under consideration. The least disturbed environments are designated as level I areas to which the strictest ecological ...
Effectiveness of impermeable barriers for retardation of pollutant migration /
(1983)
This paper presents the results of the analysis of the movement of contaminated ground water under or through an imperfect barrier. The first phase of the analysis consists of the development of an analytical solution for ...
Design of a general methodology for the evaluation and categorization of an environmental program with special reference to Costa Rica.
(1982)
This research essentially consists of two parts. In the first part, methodological studies were prepared as the basis for the development of the general methodology by which each government or institution can adapt and ...
