Hydraulic Design Algorithms For Upgrading And Enhancing Water Distribution Systems, Don J. Wood, William T. Gilbert

KWRRI Research Reports

The primary objective of this work was to develop algorithms for directly determining design characteristics for effectively enhancing, modifying or adding to existing water distribution systems. This is accomplished by modifying the basic hydraulic network equations to explicitly determine required design parameters to just meet specified conditions. Initially work was completed on directly determining pipeline diameters and directly determining pipeline and network resistance characteristics. This work was published in technical journals and established the feasibility of the approach but did not demonstrate the scope and versitility of the proposed approach. In this report a general approach is developed and tested …

Western Water Law in Transition (Summer Conference, June 3-5)

Conference organizers and/or faculty included University of Colorado School of Law professors James N. Corbridge, Jr., Lawrence J. MacDonnell, Richard B. Collins, David H. Getches and Charles F. Wilkinson.

The prior appropriation doctrine has governed the allocation and use of water in the western United States since the 1850s. The shifting nature of water demand is bringing about changes in the traditional legal system. This conference will consider the fundamental principles of the prior appropriation doctrine together with the important new developments in the law now underway throughout the West.

Selecting Non-Point Source Pollution Treatment Practices Using Linear Optimization, John Gardy Garland Iii

Civil & Environmental Engineering Theses & Dissertations

This paper provides a case study application of a linear optimization program as a water quality management tool. The optimization program seeks to minimize the cost of nonpoint source pollution control by selecting the best combination of pollution control management practices for Hampton, Virginia. The management practice options are grass swale roadways, porous pavers, ponds, detention basins and fertilizer management education. Management practice selection is limited by constraints on land-use and water quality. Pollutants evaluated are total nitrogen, total phosphorus, suspended solids, fecal coliforms and biochemical oxygen demand (five-day). The value in the water quality constraints for pollution loading on …

Groundwater Management By Linear Programming, Seungho Song

Civil & Environmental Engineering Theses & Dissertations

Three hydraulic optimization models are developed. These models combine the finite difference equations of two-dimensional groundwater flow in composite aquifers with various linear programming techniques. The hydraulic submodel employed in these hydraulic optimization models is so versatile that it accounts for time varying pumpage, leaky artesian conditions, a variety of boundary conditions, induced infiltrations from streams or rivers, and conversion from artesian to water table conditions. The objective of submodel 1 is to maximize the total hydraulic head from pumping wells at the end of a study period. The objective of submodel 2 is the same as submodel 1, but …

Treatment Process Optimization At The Lee Hall Water Treatment Plant Newport News, Virginia, Marcy Granum Garnett

Civil & Environmental Engineering Theses & Dissertations

Various methods can be used in operating a water treatment plant. It is desirable to produce good quality water as efficiently and economically as possible. This study evaluates each phase of operation at the Newport News (Lee Hall} water treatment plant for overall efficiency.

This study begins by giving a detailed description of the Lee Hall water treatment plant. The description includes sources of water, a description of each treatment process, a plan view of the treatment plant, and a flow diagram of the treatment plant.

Based on the raw water data, flow rates, and the treatment plant characteristics, the …

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. …

Hydraulic Analysis Of Surcharged Storm Sewer Systems, Don J. Wood, Gregory C. Heitzman

KWRRI Research Reports

Surcharge in a storm sewer system is the condition in which an entire sewer section is submerged and the pipe is flowing full under pressure. Flow in a surcharged storm sewer is essentially slowly varying unsteady pipe flow and methods for analyzing this type of flow are investigated. In this report the governing equations for unsteady fluid flow in pressurized storm sewers are presented. From these governing equations three numerical models are developed using various assumptions and simplifications. These flow models are applied to several example storm sewer systems under surcharge conditions. Plots of hydraulic grade and flow throughout the …

Bulletin 3929 - Irrigation In Western Australia, K S. Cole

Bulletins - 3000 - 3999

Irrigation is essential in many parts of the world to produce essential food and profitable cash crops. Generally, those areas of land with less than 360 mm of rain spread over a distinct wet season of several months cannot grow crops for food or cash on rainfall alone. Then irrigation becomes necessary unless some peculiarity such as an oasis exists.

A Model To Investigate The Influence Of Suspended Sediment On The Mass Transport Of A Pollutant In Open Channel Flow, Raymond Scott Chapman

Civil & Environmental Engineering Theses & Dissertations

The environmental impact of the transport of pollutants in open channel flow has for many years been of interest due to the continuous introduction of heavy metals, pesticides, herbicides, and other foreign substances into natural waterways. In order to fully understand this transport process, it-is necessary to examine the significance of its individual components. In the present study an explicit two-dimensional finite difference model, designed to investigate the influence of suspended sediment on the pollutant transport process, is presented. Specific attention is directed toward examining the role of suspended sediment in 1) the turbulent vertical transport mechanism in a stratified …

An Engineering Solution To Improve Water Quality In A Tidal Lagoon, Richard Warren Price

Civil & Environmental Engineering Theses & Dissertations

Rising demand for better water quality stimulated research and development of ways to improve the quality level in existing as well as proposed water systems. At present, most of the solutions focus on biological and chemical processes.

Many natural or man-made water bodies act as receivers for both point and non-point pollution sources. Employment of biological and chemical treatment has proved successful in many of these cases; however, in some cases a more natural physical solution of an engineering mode would be more desirable. A "flushing" technique using the tidal fluctuation as a driving force has been investigated and the …

Bulletin 3933 - Trickle Irrigation For Home Gardens, K Cole

Bulletins - 3000 - 3999

The use of trickle irrigation in the home garden can save money, time and water.

Trickle irrigation is a concept first used in glasshouses in England, then applied to field crops in Israel and developed and refined in Australia and America. Today it is widely used in orchards, vineyards, vegetable gardens and now has gained wide acceptance in the growing of ornamental plants.

Any good trickle system uses small quantities of water over an extended period of time. In the home garden, flows of 2.25 litres to 4.5 litres per hour are usual though for small shrubs lesser amounts may …
