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, publisherIn 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.Item Open Access 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, publisherThis 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.Item Open Access Analysis of watersheds and river systems: short course(Colorado State University.

Libraries, 1977-02) Walters, Wallace H., author; Colorado State University, publisherItem Open Access 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, publisherThe 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.Item Open Access History of morphologic changes: Tillatoba, Abiaca, Pelucia, and Topashaw creeks, Yazoo Basin, Mississippi(Colorado State University. Libraries, 1982) Watson, Chester C., author; Colorado State University, publisherThe objective of this report is to summarize the morphologic history of four channels in the north-central Mississippi which lie within the Gulf Coastal Plain physiographic province. Each channel flows in a general east-to-west direction between latitude 33° 15' and 34°. Tillatoba, Pelucia, and Abiaca creeks originate in the Loess Bluffs subdivision of the physiographic province, and flow into the flat area known as the Yazoo Delta. Topashaw Creek is contained in the North-Central hills subdivision, flowing into Grenada Lake Reservoir. Soil erosion in the watershed and channel, and flooding due to both underfit and sediment-choked channels have been persistent problems since the beginning of European settlement of the watershed in the 1830's.Item Open Access Infrared thermometry to estimate crop water stress index and water use of irrigated maize in northeastern Colorado(Colorado State University. Libraries, 2012) Taghvaeian, Saleh, author; Chávez, José L., author; Hansen, Neil C., author; Molecular Diversity Preservation International, publisherWith an increasing demand of fresh water resources in arid/semi-arid parts of the world, researchers and practitioners are relying more than ever on remote sensing techniques for monitoring and evaluating crop water status and for estimating crop water use or crop actual evapotranspiration (ETa). In this present study, infrared thermometry was used in conjunction with a few weather parameters to develop non-water-stressed and non-transpiring baselines for irrigated maize in a semi-arid region of Colorado in the western USA. A remote sensing-based Crop Water Stress Index (CWSI) was then estimated for four hourly periods each day during 5 August to 2 September 2011 (29 days). The estimated CWSI was smallest during the 10:00-11:00 a.m. and largest during the 12:00-13:00 p.m. hours. Plotting volumetric water content of the topsoil vs CWSI revealed that there is a high correlation between the two parameters during the analyzed period. CWSI values were also used to estimate maize actual transpiration (Ta). Ta estimates were more influenced by crop biomass rather than irrigation depths alone, mainly due to the fact that the effects of deficit irrigation were largely masked by the significant precipitation during the growing season. During the study period, applying an independent remotely sensed energy balance model showed that maize ETa was 159 mm, 30% larger than CWSI-Ta (122 mm) and 9% smaller than standard-condition maize ET (174 mm).Item Open Access History of flooding at Colorado State University (1902, 1938, 1951, 1992 and 1997)(Colorado State University. Libraries, 1998-09) Charlie, Wayne A., authorNewspaper reports, photos, rainfall, and damage estimates are presented for the floods of 1902, 1938, 1951 and 1997 which impacted the campus of what is now know as Colorado State University. The September 20 and 21, 1902 flood caused no reported damage to the campus probably because the few buildings built west of the railway track were on high ground. The September 2 and 3, 1938 flood caused flood damage to the Library, Heating Plant, College Avenue Gym/Field House, Physics Building, Museum, steam tunnels, Johnson Hall (Student Union) and flooding of the oval and Tennis Courts. Over $10,000 (1938 dollars) of flood damage to the museum alone was reported. The August 3, 1951 flood caused flood damage to the Library, Heating Plant, College Avenue Gym/Field House, Electrical Engineering (formally the Museum), Physics, steam tunnels, Johnson Hall (Student Union), Old Braiden Hall Kitchen and flooding of the Oval and Tennis Courts. The 1951 campus flood resulted in $270,000 (1951 dollars) of flood damage to the campus. The June 24, 1992 flood caused some flood damage to Forestry, Heating Plant and the Administration Annex. The 1992 campus flooding resulted in $75,000 (1992 dollars) of flood damage on campus. The July 28, 1997 flood caused major flood damage to the Heating Plant, College Avenue Gym/Field House, Gibbons (formerly the Museum and the Electrical Engineering Building), Occupational Therapy (formerly the Physics Building), steam tunnels, Johnson Hall, Administration Annex, Morgan Library, Lory student center, Engineering, Education, Eddy, International House, University Health Services, Old Dog Colony and flooding of the Oval, Tennis courts/parking lot north of Engineering. The 1997 flood resulted in $100 million (1997 dollars) of flood damage to the campus. Several campus buildings and areas have flooded several times. The old Library (Music), Heating Plant, College Avenue Gym/Field House, Gibbons (old Museum and Electrical Engineering), Occupational Therapy (formerly Physics) and Johnson Hall (old student Union) flooded in the 1938, 1951 and 1997 floods. These six buildings were constructed after the 1902 flood. Morgan Library, Lory Student Center, Engineering, Education, Eddy, International House, University Health Services and the Old Dog Colony were constructed after the 1951 flood.
