A Study Of Feasibility Of State Water User Fees For Financing Water Development, Daniel H. Hoggan, O. W. Asplund, J. C. Anderson, D. G. Houston
Reports
Water user fees imposed by a state on major water uses is a possible new alternative source of state water development funds. A fee, similar to an excise tax, might be charged for the use of the water resource per se, which in a number of states is declared to be the property of the public of the state. States generally have not employed such fees as a source of operating funds for water agencies or of development capital. Only in the area of water based recreation-fishing, coating, camping, etc.—have states extensively employed user fees. The revenues from these fees, …

Series Intermittent Sand Filtration Of Wastewater Lagoon Effluents, David W. Hill, J. H. Reynolds, D. S. Filip, E. J. Middlebrooks
Reports
Previous researches have found single stage intermittent sand filtration to be a feasible and economic means of upgrading wastewater lagoon effluent to meet future standards. However the major constraint on their use has been the length of the filter runs. Laboratory scale and pilot-scale series intermittent sand filtration of wastewater lagoon effluents has been found to substantially increase the length of filter runs as well as produce a high quality effluent able to meet future standards. Higher loading rates were round to be possible with series intermittent sand filtration. The operation consistently produced an effluent meeting present Utah “Class C” …

Effects Of Soil Heterogeneity On One-Dimensional Infiltration, Charles Courette, Roland W. Jeppson
Reports
A parameter study for heterogeneous infiltration was performed employing a one-dimensional computer program. Soil heterogeneity was defined by linear variations of soil parameters. From the solutions obtained, the instantaneous and accumulative infiltration rates were correlated versus the rate in which the parameters varied in the soil profile. The end result being coaxial graphs from which a relative infiltration rate may be obtained by inputting time and the rates of change of various soil parameters.

Reports
Frequency analyses of more than 1,000 small watersheds in the United States and Puerto Rico were used to develop the estimation method for design of peak flow for ungaged watersheds. This method, called the Federal highway Administration (FHWA) method, is conceptually similar to the Bureau of Public Roads (BRP) method developed by W. D. Potter. The FHWA method relates the runoff peak to easily determined hydrophysiographic parameters and is intended for use on watersheds smaller than 50 square miles. The concept of risk is incorporated inot the design procedure. The risk is the probability that one or more events will …

A regional water quality control model is developed by linking a steady-state water quality simulation model with an optimization model. The water quality simulation model can be applied to complex river systems with both point and nonpoint loads using multiple interdependent pollution parameters described by either linear or nonlinear equations. Twelve water quality parameters can be modeled simultaneously: four non conservative constituents (or conservative constituents if the decay rate is set equal to zero); coliform bacteria (MPN); phosphorus; biochemical oxygen demand (BOD); ammonia (NH3); nitrate (NO3); dissolved oxygen (DO); temperature (°C); and algae. The water quality model is used to …

Estimation Theory Applied To River Water Quality Modeling, David S. Bowles, William J. Grenney, J. Paul Riley
Reports
The extended Kalman filter (EKF) is used to represent BOD, DO, and nitrogen cycling in a 36.4 miles (58.6 km) stretch in the Jordan River, Utah, under the assumption of steady-state conditions. Approximate minimum variance estimates of the water quality parameters are provided by the EKF filter. These estimates are obtained through a combination of two independent estimates of the state of the river water quality system: (1) predictions of the system state from a "phenomenologically meaningful" process model of the biochemical and stream transport processes; and (2) measurements of the water quality parameters. These two estimates are combined by …

Rural Domestic Water System Peak Flows And Design Innovations, Optimal Water Planning Series, Trevor C. Hughes, Yukio Kono, Ronald Canfield
Reports
Planning engineers commonly use generous factors of safety for peak flow estimates in urban water supply systems both as a hedge against unforeseen growth and because economies of scale result in relatively low user costs even with such reserve capacity. Transplanting of such design criteria into the rural setting, however, simply does not work. The low density portions of rural domestic systems require very realistic design criteria or the construction costs become infeasible for the small number of customers involved. Peak instantaneous flow rates in a Utah rural system were measured continuously during two summers on three dead-end lines serving …

A method utilizing ice crystals to circumvent nucleation processes in cloud seeding activities is discussed in the framework of nuclei activation concepts. Ice, in the form of small crystals, would be a highly efficient cloud seeding materia up to 0 degrees Celsius. The lower limit on humidity would necessitate dispensing the crystals into air that is saturated with respect to ice but no requirement for 100 percent RH(relative humidity) was found. In fact, the lower limit varies with temperature linearly from about 95 percent RH at -5 degrees Celsius to 75 percent RH at -30 degrees Celsius. Preparation of small …
