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...

Use of Atmometers in Estimating Evapotranspiration
Studies conducted by the California Department of Water Resources during the past 10 yr show that Livingston black and white spherical atmometers provide a practical means of estimating...

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...

Review of Small Basin Runoff Prediction Methods
The available methods of predicting storm runoff from small watersheds and the factor which limit their use and predictive accuracy are reviewed to a deliberately broad-brush treatment...

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...

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...

Estimating Pan Evaporation and Evapotranspiration from Climatic Data

Discussion of Estimating Pan Evaporation and Evapotranspiration from Climatic Data

Weather Modifications, University of Wyoming
A general description is given of the weather modification research conducted by the Natural Research Institute of the University of Wyoming for the purpose of precipitation increase....

River Flood Flows, Forecasts and Probabilities
River flows are forecast from meteorological and snow data. The forecasting system is based on an analogy with a highly damped spring mass system, the input to this system being the snowmelt...

Long Range Potential of VTOL Aircraft
The application of VTOL (Vertical Takeoff and Landing) to short haul aircraft, supersonic transports, and space launchers are described. VTOL potential as a means of providing a new and...

Irrigation Water Requirements of Lawns
Irrigation water requirements for lawn grasses can be estimated by an empirical formula when adequate climatological data are available. The modified Blaney-Criddle formula can be used...

Irrigation Planning Using Climatological Data
A number of water balance models are available that use climatological data. Several research workers have used models of this type for irrigation planning. It is shown that this method,...

Weather Modification
A review is given of the current status of attempts to increase precipitation by artificial means. Major research efforts are being made on this problem, both in the United States and...

Civil Aviation to 1970
For the period to 1970, an increase of up to 2-1/2 times the 1960 passenger-mile traffic is expected. Increase in air freight is more uncertain and will depend primarily on the extent...

All-Weather Landing Systems
The development of an all-weather landing system will require several intermediate steps to assure the reliability of the procedures and equipment. The feasibility is examined for both...
