Wolf Creek Dam: A Case Study Of Foundation Remediation For Dams Built On Karst Foundations, Kyla Justene Erich
Wolf Creek Dam: A Case Study Of Foundation Remediation For Dams Built On Karst Foundations, Kyla Justene Erich
Masters Theses
"Wolf Creek Dam was completed in 1952 as a 5,736-foot long and 258-foot high combination embankment-concrete gravity dam. Its storage capacity of 6 million acre feet makes it the ninth largest reservoir in the nation. The dam was built on a heavily karstified limestone foundation and began exhibiting signs of excess foundation seepage in late 1967. This led to extensive corrective work in the 1970s beneath the earthen core of the embankment to reduce underseepage. In 2006 an independent assessment by the Dam Safety Action Classification (DSAC) Peer Review Panel recommended that Wolf Creek Dam exhibited "Urgent and Compelling" foundation …
A Regional Study Of Landslide Hazards And Related Features In The Upper Indus River Basin, Northern Pakistan, Muhammad Farooq Ahmed
A Regional Study Of Landslide Hazards And Related Features In The Upper Indus River Basin, Northern Pakistan, Muhammad Farooq Ahmed
Doctoral Dissertations
"A spatial landslide inventory is a fundamental step preparatory to developing an understanding of regional landslide hazards. The techniques honed for this regional landslide mapping study began with compiling a stitched shaded topographic map of the Upper Indus River watershed; using remotely-sensed topographic maps from Russia combined with ASTER DEM 30m resolution data. Topographic recognition keys were then employed to aid in the visual identification and delineation of past landslides, rockslide avalanches, and landslide dam sites. The first order reconnaissance level inventory excerpted 2,254 landslides (mostly deep seated translational and complex slides) along the main stem of Indus River, land …
A Modification Of Freeze-Core Technology For Collecting Granular Fluvial Sediment Samples, David Charles Smith
A Modification Of Freeze-Core Technology For Collecting Granular Fluvial Sediment Samples, David Charles Smith
Masters Theses
"The presence of coarse grained sediment can potentially reduce the effectiveness of conventional sampling methods in recovering fluvial sediments. A modification to freeze-core technology was used to collect fine grained sediments for the purpose of characterizing the extent of heavy metal contamination in fluvial deposits that contain significant amounts of coarse-grained material such as cobbles and boulders. This material greatly reduces the effectiveness of conventional sampling methods. This method uses 2.5-cm and 2.9-cm diameter by 30-cm long finned samplers that were mechanically- and hand-driven into the ground. The sediment is frozen to the outside of the sampler by injecting liquid …
Characterization Of Rabinal, Guatemala Clay And Development Of An Engineered Surrogate For The Purpose Of Laboratory Study, Lara Anne Hubbel
Characterization Of Rabinal, Guatemala Clay And Development Of An Engineered Surrogate For The Purpose Of Laboratory Study, Lara Anne Hubbel
Masters Theses
"Ceramic pot filters (CPFs) have been proven to be an effective, low cost household water treatment system that are commonly used in third world countries. They are made using local clay, burn out material and colloidal silver or silver nitrate. Challenges faced by researchers include difficulty in acquiring filters from their manufacturing facilities without incurring damage and the cost of shipping. Acquiring the clay material used to make the filters is also difficult due to the cost of shipping and permits necessary to import soil. There have been studies conducted that compared laboratory made CPFs made with native clay and …
Regional Geomorphic Analysis And Gis Susceptibility Mapping Of Landslides In The Blue Nile And The Tekeze River Basins Of Ethiopia, Elamin Hassan Dai Ismail
Regional Geomorphic Analysis And Gis Susceptibility Mapping Of Landslides In The Blue Nile And The Tekeze River Basins Of Ethiopia, Elamin Hassan Dai Ismail
Doctoral Dissertations
"The Plateau region of Ethiopia lies within a seismically active continental extensional regime, which is being rapidly incised by the Blue Nile and the Tekeze Rivers. Extremely large landslides pose serious hazards in this highly populated region (>27 million), which is in the process of developing its hydrologic resources. This research sought to develop cost-effective methods to compile regional landslide inventory and landslide susceptibility maps, using geomorphic tools and GIS technologies. This work also sought to evaluate the relationships between landslide dams and knickpoints, caused by channel bed incision from those caused by slope failures, by utilizing identified knickpoints …
