- A stochastic model for pollution and dissolved oxygen in streamsThayer, Richard P.; Krutchkoff, Richard G. (Water Resources Research Center, Virginia Polytechnic Institute, 1966)The problem of the pollution of the rivers and estuaries of this nation and the world is now receiving considerable attention, and rightly so. Many rivers are so grossly polluted that there is scum on the surface and the odor of methane and hydrogen sulfide is noticeable. Consequently, there is a danger to health. For example, part of the Hudson River in New York is so foul that only eels can live in it. The lower Mississippi River is full of fish that have died. Through a great effort over a long period of time, the sewage load on the Potomac River has been reduced. The river has improved greatly and the more desirable species of fish are beginning to return...

- Hydrologic aspects of no-tillage versus conventional tillage systems for corn productionShanholtz, Vernon O.; Lillard, James H. (Water Resources Research Center, Virginia Polytechnic Institute, 1968)For many years one of the goals of tillage research at Virginia Polytechnic Institute has been to develop a system which (a) reduces the amount of tillage required, (b) maintains an open-sail structure conducive to good rainfall intake and storage, and ( c) makes more beneficial use of the residues of preceding crops for minimizing evaporation, soil erosion and runoff losses. From these investigations evolved the no-tillage system. With this system the crop is planted directly into a chemically killed sod or crop residue with no prior mechanical seedbed preparation, thereby utilizing vegetation from the preceding crop for surface mulch.

- Multicomponent mass transport in aqueous and membrane systemsWills, George B. (Water Resources Research Center, Virginia Polytechnic Institute, 1968)Project Objectives The basic objective of this study has been to develop and critically test models for multicomponent mass transport in aqueous and membrane systems. More specifically, this basic aim has been pursued through the following set of sub-objectives:
- Selecting a set of aqueous systems for detailed study followed by a comprehensive literature review to collect all pertinent data for the selected systems.
- Measuring multicomponent mass transport data in a selected system over a wide range of compositions.
- Developing a general mathematical model for multicomponent mass transport
- Obtaining optimum parameters for the mass transport models developed in (3).
- Determining whether the effective water of hydration of solutes in aqueous solutions can be reasonably determined as that value giving the best fit of the experimental transport data.

- Computer system for the reduction and analysis of soil moisture dataShanholtz, Vernon O. (Water Resources Research Center, Virginia Polytechnic Institute, 1968)The quantitative evaluation of soil moisture through extended periods is a basic requirement in areas of research related to engineering, agriculture, and the life sciences. Invariably, it involves the processing and analysis of thousands of measurements. These are most often taken with nuclear soil moisture monitoring equipment. It is the purpose of this report to present a system of computer programs, written in Fortran IV for the IBM 7040/1401 system, but readily convertible to other systems, designed specifically to expedite the reduction and analysis of soil moisture data. The system contains 3 unique and independent programs or sections. The first section consists of a reduction of the basic field data, the second section is a coding, summary and plotting routine, and the third section is an analysis of variance routine. These separations allow for a more general approach in the reduction procedure. Data are collected in the field, key punched from the field sheets, and processed in exactly the same order as they are obtained....

- Geologic control of rainfall-runoff relations in the Peak Creek Watershed, Pulaski and Wythe Counties, VirginiaCooper, Byron Nelson, 1912-1971 (Water Resources Research Center, Virginia Polytechnic Institute, 1969)
- The effect of pumped-storage reservoir operation on biological productivity and water qualitySimmons, George M. Jr.; Neff, Stewart E. (Water Resources Research Center, Virginia Polytechnic Institute, 1969)With the increased utilization of our water resources by a growing population, intelligent management of these resources, giving full consideration to all the relevant factors, becomes essential. Pumped-storage hydroelectric projects have been developed giving primary emphasis to the factors which relate to the generation of electricity. These projects can also provide a means of reducing stream pollution effects through stream flow augmentation and by lessening the effects of thermal stratification...
