Frequency of Potential Evapotranspiration Rates in Great Central Plains
Because of strong advection in the region, ET rates in the eastern Great Plains must frequently be expected to exceed the energy equivalent of the net radiation (6 to 7 mm per day on clear...

Reducing Pond Evaporation with Perlite Ore
Floating solid and granular materials appear to provide a practical means of reducing evaporation losses from open water surfaces. The increased efficiency of these materials over monomolecular...

Monitoring Water Pollution By Remote Sensing
Imaging remote sensing techniques can be effectively utilized as a water pollution monitoring tool if the advantages of imaging remote sensing as applied to other fields are understood...

Dynamics of Earth Dams with Foundation Interaction
An analytical procedure to determine the dynamic properties (natural frequencies, mode shapes, and radiation damping) of dams including foundation interaction effects, which has been presented...

Viral Disinfection of Estuarine Water by UV
Experiments were conducted with viruses artificially introduced into seawater under both static and continuously flowing conditions. Under static conditions, the devitalization of each...

Viral Disinfection of Estuarine Water by UV

Loading Rates on Waste Stabilization Ponds
Pond performance is affected by temperature, solar radiation, and wind-speed; therefore, facultative pond design should reflect the influence of local climatological conditions. Ponds...

Successful Ice Dusting at Fairbanks, Alaska, 1966
The ice and snow cover of the Chena River was dusted with coal dust and fly ash in the spring of 1966 to increase the absorption of solar energy and hasten melting. Because of a near-record...

Pan Evaporation and Evapotranspiration from Climatic Data
Pan evaporation data are useful in estimating losses from reservoirs and lakes, and for estimating evapotranspiration from agricultural crops using procedures relating evapotranspiration...

Location-Design of Transportation Noise
Noise conditions found around airports and roadways are described together with procedures for rating the complaint potential of such noise in impacted inhabited areas. Various location...

Consumptive Use Estimates from Solar Radiation and Temperature

Intensity of Radiation and Rate of Sludge Drying
Field experience has indicated that drying time required by the conventionally designed and operated sludge drying beds is comparable to that required by beds modified to provide only...

Vibration Transfer from Shear Buildings to Ground
A plausible, simple mechanism is presented to illustrate vibratory energy transfer from a shear type building to the ground on which it stands. The mechanism involves wave travel and reflection...

Estimating Evapotranspiration from Solar Radiation
Measured evapotranspiration (consumptive use) data from irrigated areas in western United States were collected, re-evaluated, and combined with estimates of solar radiation. Approximately...
