Charged Membrane, Low Pressure Ultrafiltration To Treat Acid Mine Drainage Waters, Dibakar Bhattacharyya, Robert B. Grieves, Shiela Shelton

KWRRI Research Reports

Low-pressure ultrafiltration with negatively-charged, non-cellulosic membranes is shown to be a feasible process in terms of achieving the simultaneous separation of dissolved metals (and sulfate) and of suspended solids from acid mine drainage water. The process is evaluated in terms of the simultaneous achievement of good water flux without membrane fouling and of adequate ultrafiltrate quality at high water recovery for water reuse operation.

At a transmembrane pressure of 5.6 x 10⁵ N/m², water fluxes in the range of 5.8 x 10^-4 cm/sec to 12.5 x 10^-4 cm/sec could be obtained at 97% water recovery. …

A Technical Focus For Documenting The Effectiveness Of The Cooperative Owrt-Institute Water Resources Research Program, L. Douglas James

Reports

For years, the cooperative water resources research program of the Office of Water Research and Technology and the water resources research institutes in the respective states has been experiencing considerable difficulty in generating agency, congressional, and user support of a sort that attracts sufficient funding to maintain a dynamic research program. Efforts to increase support have included recruiting greater interaction with research user groups, expansion of the technology transfer program, cultivation of interaction of center directors and research users with congress, shifting requests for added funding within the research program from the allotment funding given the respective states to matching …

Changing Fields: Agricultural Land Use Changes In Nebraska 1925-1974, Donald A. Wilhite

Drought Mitigation Center: Faculty Publications

The series of graphs and maps which follow illustrate agricultural land use changes in Nebraska from 1925 to 1974. With these graphs and maps, the major agronomic crops of corn (dryland and irrigated), wheat, sorghum and soybeans are analyzed. The purpose of this analysis is to provide a pictorial history of Nebraska's ever-changing cropping system and, hopefully, to stimulate ideas and discussion with regard to trends and future directions. The Nebraska Water Resources Center is deeply interested in both the past and the future of Nebraska's agriculture because of the demands which agriculture places on the state's water resources. An …

Study Of Cumulative Growth-Inhibiting Factors In Recycled Water For Catfish Cultivation, R. W. Raible

Technical Reports

Channel catfish were grown in tanks with integral biological filters and complete recirculation of water. After the fish had resided in the tanks for 120 days, solvent extraction was performed on a portion of the tank water. Fresh pond-raised specimen channel catfish showed decreases in their heartbeat rates of about 20 percent when exposed to the extract. This metabolic disturbance is thought to be a factor in reducing the growth rate of fish held in close confinement in recirculating systems.

Turbulence Spectra Above A Vegetated Surface Under Conditions Of Sensible Heat Advection, Raymond P. Motha, Shashi B. Verma, Norman J. Rosenberg

Drought Mitigation Center: Faculty Publications

Spectra of vertical and horizontal velocity, air temperature and humidity fluctuations were analyzed from measurements made over a well-watered alfalfa crop under conditions of sensible heat advection. Vertical velocity and air temperature spectra as well as cospectra of momentum, sensible heat and water vapor were found to be dependent on atmospheric thermal stratification. These spectra and cospectra were shifted toward higher frequencies under advective as compared to lapse conditions. These results indicate that the predominant eddy sizes are relatively smaller under advective conditions. Humidity spectra, on the other hand, were independent of daytime thermal stratification conditions but were influenced by …

Stochastic Analysis For Water Quality, Ronald F. Malone, David S. Bowles, William J. Grenney, Michael P. Windham

Reports

This report demonstrates the feasibility of applying stochastic techniques to linear water quality models. The Monte Carlo, First Order, and Generation of Moment Equation techniques are applied to a long term phosphorus model of Lake Washington. The effect of uncertainty of the phosphours loading term on simulated phosphous levels is analyzed. All three stochastic techniques produced the same results. The simulated concentrations of phosphorus in the water column are very responsive to uncertainty in annual phosphorus loading, the sediment concentrations relatively insensitive. The Monte Carlo technique is shown to require the most computation time of the three stochastic techniques applied. …

Random Differential Equations In Water Quality Modeling, Brad A. Finney, David S. Bowles, Michael P. Windham

Reports

A probabilistic river water quality model is developed with the capability of determinging the joint and marginal probability density function of biochemical oxygen demand (BOD) and dissolved oxygen (DO) at any point in a river. The one dimensional steady-state model can be applied to a river system with any reasonable number of point loads and diversions and lateral surface and subsurface inflow. The model can simultaneously consider randomness in the intital conditions, inputs, and coefficients of the water quality equations. Any empirical or known distribution can be used for the initial condition. The randomness in the water quality equation inputs …

Erosion Control During Highway Construction: Volume 1, Calvin G. Clyde, C. Earl Israelsen, Paul E. Packer

Reports

Summary: Highway constuction as we know it today is a high-risk activity with respect to engendering soil erosion. In earlier days of road building, when rights-of-way were generally narrow and excavations mostly shollow, erosion was rarely a serious problem. Only occasionally was it considered necessary to design and apply specific measures for erosion control. With the advent of the superhighway involving far greater widths of right-of-way, and much deeper disturbance of the natural ground to affort the horizontal and vertical highway geometry necessary for high-speed travel, came a several fold increase in erosion potential and a direct need for specific …

Program Development Plan For An Operational Cloud Seeding Project In Utah With Evaluation Included, Geoffrey E. Hill

Reports

1. Operation Framework

In the arid climate of Southern and Central Utah, there is a continuing need to augment water supplies. While much of the water is needed for summertime use, particularly for irrigation, most of the available water is supplied by winter storms. Therefore, it is for the augmentation of the water stored naturally as snowpack at higher elevations that cloud seeding can make its greatest contribution.

Over the past several years, an attempt has been made to augment the snowpack by cloud seeding. Although there is a physical basis for expecting an increase in precipitation from a scientifically managed …

An Economic Evaluation Of The Salinity Impacts From Energy Development: The Case Of The Upper Colorado River Basin, Rangesan Narayanan, Sumol Padungchai, A. Bruce Bishop

Reports

To analyze the effect of potential energy development on water allocation and water quality in the Upper Colorado River Basin, a linear programming model is formulated. Using the model, changes in salinity are predicted. Further, least-cost strategies to maintain the established numeric salinity criteria through both structural and nonstructural alternatives are developed. The effectiveness of alternative control measures are examined within given institutional constraints. Based on cost-benefit analysis, optimal salinity levels over time are proposed. The economic feasibility of presently planned strucutral measures to reduce salinity is investigated and contrasted with nonstructural alternatives.

Erosion Control Product Testing, C. Earl Israelsen, Eugene K. Israelsen, Joel E. Fletcher, Jerald S. Fifield, Ronald V. Canfield

Reports

Introduction: Fibrex Corporation has capability for manufacturing various blends of cellulose fibers which have been used at locations throughout the country for temporarily controlling erosion on denuded land areas, and for serving as growth media for grass and other vegetation. Soil and climatic conditions vary greatly where these products are used, and it is not possible to determine by observation whether one is more effective than another in controlling erosion or promoting vegetative growth. Fibrex is desirous of knowing with some degree of confidence which products have the highest level of erosion control so that additional efforts can be directed …

The approach that was used includes six basic components: 1) the clarification of current planning theory as it pertains to both water and land use planning, 2) analysis and review of historical and current land use planning practices, 3) review of historical and current land use planning …

Studies On Viruses In Water, Rex S. Spendlove, Bill B. Barnett, Dennis B. George, Dennis J. Adams, Stanley F. Hayes, Ronald B. Dean, David Ridinger, Darwin L. Sorensen

Reports

A new procedure for the detection of viral antigens in fecal material was developed. The test is performed by first diluting a fecal sample with phosphate buffered saline to give a liquid consistency. The pH is then adjusted to 8.5-9.0 and the solids are allowed to settle for five minutes. Supernatant fluid from above the fecal sediment is placed on the upper surface of a well of an inverted Immulon microtiter plate and incubated for one hour at 37 degrees C to allow virus to adsorb to the plastic. The Immulon plate is then washed three times with a Tween …

Since nearly every water resource managment choice has two or more sides, differences must be resolved in decision making. Equitable resolution requires an understanding of the reasons for the differences. These reasons originate in the implemented plans have physical-environmental, economic, social, cultural, and political impacts at levels ranging from local to national or international in scope. Decisions are made by individuals and groups impacted in all of these dimensions and at all of these levels; the decisions generate additional impacts; and the entire interactive process changes water management practice in ways outside the control of any one decision point or …
