Surface Water Interaction With The Flood Plain In The Lower Virgin River, Clark County, Nevada, Jeffrie L. Pompeo
Surface Water Interaction With The Flood Plain In The Lower Virgin River, Clark County, Nevada, Jeffrie L. Pompeo
UNLV Theses, Dissertations, Professional Papers, and Capstones
Development of existing surface water rights on the Virgin River would decrease Southern Nevada's dependency on the Colorado River. Three monitoring sites were established to examine the relationship between Virgin River surface water flows and the floodplain aquifer. Automated water level measuring devices were installed in piezometers and wells to continuously track water levels and flow direction. Pump tests were conducted to establish the hydraulic parameters of the floodplain aquifer. Water chemistry data was analyzed to help determine the correlation between the floodplain aquifer and Virgin River water. Precipitation, recharge, streamflow and ET estimates were used to discuss water budgets. …

The Mayan Ice Cap: Glacial Geology And Paleoclimate Of The Northern Guatemalan Highlands, Alex Joseph Roy
UNLV Theses, Dissertations, Professional Papers, and Capstones
The Sierra de los Cuchumatanes region of the northern Guatemalan highlands supported a large plateau ice cap with an area of -40 km2 along with a group of 5 cirque glaciers -1 to 2 km2 during the local last glacial maximum (LLGM). A comprehensive mapping reconstruction of the northern Guatemalan highlands is presented here, including glacial geology and an estimate of maximum ice limits from physical evidence and computer modeling. The glacial geologic map was produced via field mapping with global positioning system (GPS) surveying combined with aerial stereo photographic and topographic map analysis. This new field work on moraine …
