Automation of a model for predicting soil moisture and soil strength (SMSP Model) by M. H Smith( Book )

3 editions published in 1973 in English and held by 7 WorldCat member libraries worldwide

The soil moisture strength prediction (SMSP) model is a composite of the methods developed at the U.S. Army Engineer Waterways Experiment Station for predicting daily soil moisture contents and strengths (in terms of cone index and rating cone index) of soil layers at depths of 0-15 and 15-30 cm. Information required by the model includes soil moisture accretion and depletion relations, field maximum and minimum soil moisture contents, moisture content at start of prediction, soil dry density, soil moisture-strength relation, daily rainfall amounts, and minimum rainfall amount required for accretion. The main text of the report includes a discussion of the structure, operation, use, limitations, and mathematics of the model. Appendixes A-G include detailed flow charts and listings of the computer program; listings, organization, and format of input data; examples of prediction runs and graphic displays of results; and procedures for converting output data to terms required by the airfield construction effort model
Trafficability predictions in tropical soils : report 3 : Panama study no. 2 (October 1961-September 1963) by Alvin R McDaniel( Book )

1 edition published in 1971 in English and held by 4 WorldCat member libraries worldwide

The soil-moisture prediction method for U.S. soils was applied to sites located in the the Panama Canal Zone to determine whether the method was applicable for the prediction of moisture content of tropical soils. Factors necessary for the predictions were obtained at specific sites, and analysis of data shows that the method is applicable to Panama soils. Groundwater did not have an appreciable influence on soil-moisture depletion since drainage from the 0- to 12-in. layer was rapid. An analysis of strength data showed a highly significant relation between moisture content and cone index, and a lesser degree of significance between moisture content and rating cone index. No relation was found between moisture content and remolding index. On the basis of rating cone index, the trafficability of the residual soils was considered good. Trafficability of the alluvial marshland soils was considered good during the dry season and poor during the wet season
Field tests and experiments on visibility modification by J Latham( Book )

1 edition published in 1988 in English and held by 1 WorldCat member library worldwide

Laboratory experiments on the scavenging of wet aerosol - of controlled sizes ranging from about 0.3 to 50 micrometers - by electrically charged collector drops have been performed. The consistent result was of a pronounced increase in measured values of collection efficiency above those found in the absence of electrical forces. Water drops of characteristic size around 0.1mm, carrying charges of several tenths of the Rayleigh limit, swept out essentially uncharged water droplets of size within the condensate size-band for fogs, with collection efficiencies E in the range approximately 20 to 25 (the corresponding nonelectrical values are significantly less than unity). A crude theoretical model of the capture process provided values of E in reasonable agreement with those measured. The principal of the technique would be to introduce highly charged drops into a fog. These would scavenge fog droplets with great efficiency - as indicated in the laboratory experiments - and the collector drops (now much larger, having swept out large numbers of fog droplets) would settle from the fog under the influence of gravity, leaving it with a substantially reduced liquid water content - and correspondingly enhanced visibility
The role of electrical forces in the development and dissipation of clouds and fogs by J Latham( Book )

1 edition published in 1972 in English and held by 1 WorldCat member library worldwide

Several lines of investigation have been pursued in the second year of the contract. These include: the coalescence efficiencies of water drops; the production of satellite droplets by colliding water drops and the resulting effect upon rainfall rate; the influence of electric forces upon the interaction of cloud droplets; the calculation of the effectiveness of various hygroscopic materials as fog modification agents. The studies of the interactions of colliding water drops are now complete and will comprise the main body of the report. The investigation of the hygroscopic material is also complete and the work on the influence of electric forces upon the interactions of cloud droplets is well under way, although the experiment is not yet completely operational.
