    • Comparison of Methods for Determining Soil Hydraulic Characteristics 
      Howell, T. A.; McFarland, M. J.; Reddell, D. L.; Brown, K. W.; Newton, R. J.; Humphreys, K. B. (Texas Water Resources Institute, 1980-12)
      An adequate description of soil moisture movement is necessary for solution of agriculturally oriented problems such as irrigation, drainage and runoff control. Three approaches for determining the hydraulic properties of ...
    • Determining the Transpiration Rate of Peach Trees Under Two Trickle Irrigation Regimes 
      Howell, T. A.; McFarland, M. J.; Reddell, D. L.; Brown, K. W.; Newton, R. J.; Rodriguez, P. B.; Van Bavel, C. H. M.; Reeder, E. L. (Texas Water Resources Institute, 1980-12)
      The scientific design and management of a modern irrigation system requires that the designer or manager have knowledge of site and plant criteria such as infiltration, drainage, soil fertility, plant water needs, and plant ...
    • Heat Transport in Groundwater Systems--Finite Element Model 
      Grubaugh, E. K.; Reddell, D. L. (Texas Water Resources Institute, 1980-08)
      Solar energy is a promising alternate energy source for space heating. A method of economic long term solar energy storage is needed. Researchers have proposed storing solar energy by injecting hot water heated using solar ...
    • Heat Transport in Groundwater Systems--Laboratory Model 
      Reed, D. B.; Reddell, D. L. (Texas Water Resources Institute, 1980-08)
      Solar energy is a possible alternate energy source for space heating. A method of economic long term solar energy storage is needed. Researchers have proposed storing solar energy by heating water using solar collectors ...
    • Measurement and simulation of miscible displacement in soils and the prediction of dispersion coefficients 
      Smajstrla, A. G. (Texas A&M University. Libraries, 1977)
      Experimental and numerical simulation studies of solute transport processes in porous media were conducted to gain increased understanding of the phenomena that occur as solutes and water move through porous media. A ...
    • Net Benefits to Agriculture from the Trinity River Project, Texas 
      Fish, B.; Williford, G.; Elling, H.; Lacewell, R. D.; Hosch, P.; Griffin, W.; Reddell, D. L.; Hiler, E. A.; Bausch, W. (Texas Water Resources Institute, 1976-07)
      The purpose of this study was to estimate the agricultural benefits due to flood protection provided by the proposed Trinity River Project. The area examined was the land located between the 100-year flood plain with the ...
    • Numerical simulation of two-phase flow and dispersion in saturated-unsaturated porous media 
      Khaleel, Ra (Texas A&M University. Libraries, 1977)
      A three-dimensional model describing the two-phase (air-water) fluid flow equations in an integrated saturates-unsaturated porous medium was developed. Also, a three-dimensional convective-dispersion equation describing ...
    • Optimal Use of Groundwater and Surface Water to Reduce Land Subsidence 
      Acosta-Gonzalez, G.; Reddell, D. L. (Texas Water Resources Institute, 1980-08)
    • Response of Peanuts to Irrigation Management at Different Crop Growth Stages 
      Howell, T. A.; McFarland, M. J.; Reddell, D. L.; Brown, K. W.; Newton, R. J.; Dahmen, P. (Texas Water Resources Institute, 1980-12)
      Past irrigation research on peanuts has shown that when the plant is exposed to soil moisture stress at different crop growth stages, different responses seem to exist between the Spanish and the Florunner peanut varieties. ...
    • Simulation of Pollutant Movement in Groundwater Aquifers 
      Khaleel, R.; Reddell, D. L. (Texas Water Resources Institute, 1976-09)
      A three-dimensional model describing the two-phase (air-water) fluid flow equations in an integrated saturated-unsaturated porous medium was developed. Also, a three-dimensional convective-dispersion equation describing ...
    • Single Location Doublet Well to Reduce Salt-Water Encroachment: Phase I-Numerical Simulation 
      Reddell, D. L. (Texas Water Resources Institute, 1983-09)
      C. E. Jacob received patents in 1965 for a single location well doublet that would produce fresh water overlying salt-water without upconing of the heavier salt-water and pollution of the fresh water zone. No known evaluation ...
    • Soil water evaporation and transpiration from a row crop at partial cover 
      Ham, Jay Matthew (Texas A&M University. Libraries, 1990)
      When crops are cultivated in a row configuration, latent heat flux from the soil (LE[s]) and crop canopy (LE[c]) influence the energy and water balance of the crop. Field experiments were conducted in Lubbock, TX to examine ...
