Optimal Allocation Of Water Among Industries In Dar Es Salaam City, Tanzania, J. I. Matondo

Tanzania Journal of Engineering and Technology (TJET)

Dar es Salaam is the city with the largest number of industries in Tanzania. However, the water demand for these industries is more than the supply. Therefore, there is a water use competing problem among the industries. Dynamic programming technique has been applied to optimally allocate the available water among the industries with the objective of maximizing the net benefits. Results reveal that, industries with the highest net return per unit of water will get the first priority of being allocated water.

Analysis And Prediction Of The Water Temperature Of The Mckenzie River, Oregon Using The Equilibrium Temperature Approach, R. Peder Hansen

Dissertations and Theses

A one dimensional, steady flow, unsteady temperature model is used to evaluate the effects of two U.S. Army Corps of Engineers (COE) dams and resulting reservoirs on hourly water temperatures of the mainstem McKenzie River from Delta Park (RM 62.1) to Leaburg Dam (RM 38.8). Both COE projects are on tributaries to the McKenzie River and at present have only bottom withdrawl capabilities.

Water temperatures were simulated using the equilibrium temperature approach with air temperature used to estimate equilibrium temperature and also using computed hourly equilibrium temperature. Results obtained using computed equilibrium temperatures were less satisfactory than results using air …

Forecasting For Local Water Management, Douglas Alan Putnam

Dissertations and Theses

Forecast models are investigated and developed for use in local water management to aid in determining short term water requirements and availability. The forecast models include precipitation occurrence and depth using a Markov chain model, temperature and solar radiation with a multivariate autoregressive model, and streamflow with autoregressive-moving average models. The precipitation, temperature, and solar radiation forecasts are used with a soil moisture model to determine water demands. A state space approach to the Muskingum-Cunge streamflow routing technique is developed. The forecast water demands and streamflow forecasts are used as inputs to this routing model. Forecast model errors and propagation …

State Space Approach To Flood Stage Estimation, Gregory Allen Jones

Dissertations and Theses

A flood routing and stage prediction model is developed using the techniques of State Space and Kalman filtering. The governing equation is the physically based hydrologic method of flood routing with the output being an optimal estimate of stage given known inputs of streamflow. These equations are developed in state space and the Kalman filter is employed to estimate the flow and river stage.

The model is applied to the Toutle and Cowlitz Rivers in the State of Washington, where the stage is affected by a shifting bed elevation. With the deterministic inputs at Mayfield Dam on the Cowlitz and …

Evaluating The Effects Of Alum With Polyelectrolyte Coagulant Aids In Treatment Of Low Turbidity Waters, Kenneth John Stockwell

Civil & Environmental Engineering Theses & Dissertations

Potable water sources usually require treatment for removal of suspended organic and inorganic particles. Conventional treatment processes incorporate chemical coagulants for removal of these suspended particles. Alum is a widely used coagulant that can provide adequate removals of turbidity. However, high alum dosages are required for treatment of low turbidity waters producing a voluminous sludge that is difficult to dewater.

Recent Federal regulations have limited disposal options for chemical sludges. This has prompted a reevaluation of coagulants and their dosages with the goal of reducing the amount of sludge produced and improving the sludge handling characteristics necessary for ultimate disposal. …

The Impact Of Public Transportation Policy To Affect Energy Conservation (A Case Study), Ali A. Selim, John T. Kretzer, Braja M. Das

UMR-MEC Conference on Energy / UMR-DNR Conference on Energy

In order that public transportation policies relating to energy conservation might be identified, correlated, and assessed, a mail survey of local, regional, state, and federal appointed and elected officials was made. This survey also included contacting members of the regional business community. Although the responses received did not constitute the complete survey mailing, they did provide insight to the individual policymaker's perception of what public policy is now in effect and how it was enacted, particularly those pertinent to energy conservation in the transportation sector.

Energy Aspects Of Rural School Bus Transportation, Kirk R. Hastain, Frank A. Gerig

UMR-MEC Conference on Energy / UMR-DNR Conference on Energy

In an effort to determine the effect of rural school bus transportation on energy consumption, a study was made of a rural school district in Central Missouri. The school district's bus system was studied, records of fuel and maintenance costs were analyzed, and discussion held with supervisor and bus drivers. An effort was made to recommend ways by which energy could be conserved, without jeopardizing the welfare of the students.

Multimodal Analysis Of The Western Coal Transportation System, Kenneth Ebeling, Kam Li

UMR-MEC Conference on Energy / UMR-DNR Conference on Energy

Points raised in the coal slurry pipeline issue imply a need for an analysis of the multimodal alternatives within the context of the existing western transportation system. In reporting the initial results of the first study of its kind, this paper includes a brief description of the data base and computer routines used to construct a base case and ideal case senerios of the western coal transportation issues.

Transporting Coal In Containers Through Pipeline -- A Feasibility Study, Henry Liu

UMR-MEC Conference on Energy / UMR-DNR Conference on Energy

A preliminary assessment of the feasibility of transporting coal in containers suspended in water moving through pipes - the concept of hydraulic capsule (container) pipelining (HCP) - is presented. The assessment includes technical (engineering), environmental, social and economic considerations. A tentative conclusion reached is that HCP transportation of coal is technically feasible (although it needs further research and development works), socially and environmentally beneficial, and economically justifiable in a number of situations.

The Linear New City -- A Pattern For New Cities Based On Efficiency Of Transportation, Public Services, And Land Use, Elbridge Wesley Bartley Iii

Masters Theses

"The linear new city is defined as a city consisting of some arrangement of relatively narrow, high-density strips, served by various mass transportation systems. Such a new city would be ideally suited to the implementation of the latest technology. The concentration of development along the transportation route would allow certain economies in the supply of utilities and services, as well as insuring that open space would be readily available around and throughout the city. The provisions for transportation, housing, and governmental control should combine to produce a better quality of life for the inhabitants of the linear new city"--Abstract, page …

High Speed Magnetically Supported Vehicles For Reducing Transportation's Degradations Of The Environment, Pravinchandra Shukla

Masters Theses

"The development of new techniques for higher speed transportation is desirable to satisfy the environmental, conservation, and economic requirements of society. Some of the important factors are presented for developing magnetically supported vehicles. A new method for improving the ratio of lift force to drag force is suggested and discussed. An application of the new technique to vehicles that would ride on a carpet of magnetism and would operate with less waste of energy is suggested "--Abstract, page ii.

Measurement Of Currents In Lake Mead With The Deep Water Isotopic Current Analyzer (Dwica), J. J. Sartoris, D. A. Hoffman, Bureau Of Reclamation

Publications (WR)

In Nov 1967, a Deep Water Isotopic Current Analyzer (DWICA) was used to study current patterns in the Boulder Basin of Lake Mead to determine if low-quality water from Las Vegas Bay might enter the Southern Nevada Water Project intake on Saddle Island. Secondary objectives were to study the general current patterns in Boulder Basin and the effect of power discharges at Hoover Dam on these currents. Results of current measurements at 3 stations in Boulder Basin are given. Observations indicate a definite possibility that low-quality water from Las Vegas Bay might enter the water intake on Saddle Island. Current …
