Role of solute-transport models in the analysis of groundwater salinity problems in agricultural areas
Leonard F. Konikow
1981, Agricultural Water Management (4) 187-205
Undesirable salinity increases occur in both groundwater and surface water and are commonly related to agricultural practices. Groundwater recharge from precipitation or irrigation will transport and disperse residual salts concentrated by evapotranspiration, salts leached from soil and aquifer materials, as well as some dissolved fertilizers and pesticides. Where stream salinity...

Hydromythology and ethnohydrology in the New World
William Back
1981, Water Resources Research (17) 257-287
From mythology, archeology, and chronicles of early explorers we can learn how early Americans viewed the cause and effect relations of hydrologic phenomena. Hopes and fears are the basis of religion, and it was through religion that water management was first practiced. Early people used their water resources to develop...
Dissolution of salt on the east flank of the Permian Basin in the southwestern U.S.A.
K.S. Johnson
1981, Journal of Hydrology (54) 75-93
Hydrogeologic studies prove that natural dissolution of bedded salt occurs at shallow depths in many parts of the Permian Basin of the southwestern U.S.A. This is especially well-documented on the east side of the basin in study areas on the Cimarron River and Elm Fork in western Oklahoma, and on...
A transient laboratory method for determining the hydraulic properties of 'tight' rocks-I. Theory

1981, International Journal of Rock Mechanics and Mining Sciences & Geomechanics Abstracts (18) 245-252
Transient pulse testing has been employed increasingly in the laboratory to measure the hydraulic properties of rock samples with low permeability. Several investigators have proposed a mathematical model in terms of an initial-boundary value problem to describe fluid flow in a transient pulse test. However, the solution of this problem...

Ground-water models for water resources planning
John E. Moore
1980, Open-File Report 80-581
In the past decade hydrologists have emphasized the development of computer-based mathematical models to aid in the understanding of flow, the transport of solutes, transport of heat, and deformation in the groundwater system. These models have been used to provide information and predictions for water managers. Too frequently, groundwater was...

Relationships between aerodynamic roughness and land use and land cover in Baltimore, Maryland
F.W. Nicholas, J.E. Lewis Jr.
1980, Professional Paper 1099-C
Urbanization changes the radiative, thermal, hydrologic, and aerodynamic properties of the Earth's surface. Knowledge of these surface characteristics, therefore, is essential to urban climate analysis. Aerodynamic or surface roughness of urban areas is not well documented, however, because of practical constraints in measuring the wind profile in the presence of...
