    Adsorption and flow of water in nearly dry Lurgi retorted oil shale
    (Colorado State University. Libraries, 1985-02) McWhorter, D. B., author; Brown, G. O., author; Department of Agricultural and Chemical Engineering, Colorado State University, publisher
    The work presented here has determined four main properties of the Lurgi spent shale. They are: 1) the critical water content above which internal drainage will occur, 2) the volume of infiltration that can be accommadated if permanent storage as a function of placement water content, 3) the rate at which water will drain if the water content is above the critical value, and 4) the rate of penetration of net infiltration through a disposal pile. To achieve the above objectives several tests have been performed. These include tests of the materials, cementing properties (hydration test, x-ray diffraction and scanning electron microscope), water holding capacity (vapor sorption and pressure plate test) and hydraulic properties (diffusivity and conductivity). The following chapters describe the testing procedures and results along with an illustrative analysis of flow in a disposal pile.

    User's manual for program CHANSEC
    (Colorado State University. Libraries, 1978-04) Simons, D. B., author; Li, R. M., author; Brown, G. O., author; Barkau, L. A., author; Civil Engineering Department, Engineering Research Center, Colorado State University, publisher
    In computer simulation of large river systems, hand modification of cross-sectional data is so time consuming that evaluation of more than a few alternative channel designs is impractical. Because of this, an interactive computer program (CHANSEC) was developed that modifies an existing set of digitized cross sections to reflect modifications such as channelization, levee placement or changes in channel roughness. The program also plots cross sections and the bed profile on a Tektronix screen or pen plotter. In only a few minutes, this program can modify the cross section file of hundreds of miles of river to reflect channelization. A manual was prepared to assist the computer user in utilizing Program CHANSEC.

    Yazoo River basin sedimentation study: cross sectional data
    (Colorado State University. Libraries, 1978-04) Simons, D. B., author; Li, R. M., author; Brown, G. O., author; Civil Engineering Department, Engineering Research Center, Colorado State University, publisher
    This manual contains the cross-sectional data used in the Yazoo River Basin Sedimentation Study. The report shows how the complex geometric system has been abstracted to allow simulations of water and sedimentation processes using a physical process mathematical model. This manual also serves as a reference for the existing cross-sectional conditions in the Yazoo River Basin, and to conditions if the proposed plan "E" modifications in addition, are implemented as designed. This manual contains longitudinal river profiles, schematics of cross-sectional locations, lists of cross sections used and plots of the cross sections.
