Cloud Seeding Interpreted through Atmospheric Water Balance
The study of the flow and storage change of water vapor in the atmosphere above the Colorado River Basin is used to interpret the results of cloud seeding experiments. Particular interest...

Orographic Cloud Seeding as a Water Resource

Modification of Convective Clouds in Northern Plains

Investigation of Deteriorated Concrete Arch Dam
Investigation of a 40-yr old concrete arch dam is described. Apparent normal weathering processes had caused deterioration to a point where repairs were necessary. Repairs were started...

Scheduling Irrigations Using Climate-Crop-Soil Data
The most important factor affecting irrigation efficiencies and crop yields is scheduling irrigations in time and amount. Overirrigation may result in waterlogged soils, a condition which...

New Water for Northern Plains
Current research follows a plan to progress from experimental projects on individual clouds (or areas less than 1,000 sq miles) to pilot projects involving several thousand square miles...

Arizona Weather Modification Research Program
The paper presented here is an interim progress review for the period ending with the fourth summer season at Flagstaff. In 1967, randomized seeding of isolated cumulus clouds was the...

Silver Iodide Generations and Public Health
Exposure of the operator of a cloud seeding generator is compared with threshold limits for prolonged exposure established by the American Conference of Governmental Industrial Hygienists....

Design of Cloud Seeding Program
Evaluation of the results of cloud seeding in test projects in mountain areas during the winter season would be speeded by the use of a natural mesoscale unit of observation, the convection...

All-Weather Tanker Terminal For Cook Inlet, Alaska
This paper describes the design and construction of a 30,000 DWT to 60,000 DWT capacity tanker loading facility constructed in Cook Inlet, Alaska for year-round operations. Particular...

Consumptive Use Derived from Evaporation Pan Data
Evapotranspiration measurements or computations provide basic information for the computation of irrigation requirements. Unfortunately, in underdeveloped or developing countries both...

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...

Hydrometerological Systems
The use and development of a hydrometeorological system designed for operational river forecasting, reservoir regulation, and river-basin management is summarized. Such a system is considered...

Integrated Operation of Reservoirs
The multiplicity in use of the available dam and reservoir sites requires a complete integration in their operation. The operation of a system of reservoirs in Kansas River Basin is described...

Evolution of Uses of Cloud-Seeding Technology
The evolution of uses of cloud-seeding technology is reviewed to determine the factors responsible for introduction of this new technology into operating systems for water resources management....

Weather Modification in the Southern Sierras
This article presents an historical account of 15 yr of continuous winter-time cloud seeding to enhance snowpack in the upper San Joaquin watershed of the southern Sierra Nevada. The project...

Determination of Water Use by Phreatophytes and Hydrophytes
Evapotranspiration from arrowweed, saltbush, and cattail, and evaporation from bare soil with depths of 2 ft to 4 ft of water, were measured in evaporimeters of 100 sq ft to 1,000 sq ft...

Grouting a Dam Cutoff in Cavernous Limestone
Cutoff treatment at Logan Martin Dam was especially important in providing a stable and watertight foundation. Complex cavity systems occurred in the fractured dolomitic limestone bedrock....

Wave Hindcasts Versus Recorded Waves
Water wave heights on Lake Michigan were calculated theoretically from meteorological data for periods of time totalling 21 days in the autumn of 1964 and the results compared with measured...
