Simulation Modeling Of Karst Aquifer Conduit Evolution And Relations To Climate, John D. Broome
Simulation Modeling Of Karst Aquifer Conduit Evolution And Relations To Climate, John D. Broome
Masters Theses & Specialist Projects
ABSTRACT Karst regions of the world that receive relatively similar amounts of precipitation display a wide variety of landscapes. It has been suggested (Groves and Meiman, 2005) that climates exhibiting larger discrete storm events have more dissolving power and consequently higher rates of conduit growth than climates with more uniform precipitation distributions. To study this concept, a computer program “Cave Growth” was developed that modeled the growth of a cross-section of a cave passage under dynamic flow and chemical conditions. A series of 46 simulation datasets were created to represent different climatic conditions. These simulations had the same total annual …
Remchlor Model Of Tritium Transport At The Made Site, Shelly Tyre
Remchlor Model Of Tritium Transport At The Made Site, Shelly Tyre
All Theses
Groundwater transport models are commonly used at sites with groundwater contamination. Models are used to study the extent of the contamination and the possible risks it poses. Contaminant transport models use properties of the aquifer and the solute to simulate how the solute moves through the aquifer. Screening level models are often used as a first modeling approach at sites to get an idea of the general trends of contaminant transport. They offer an efficient approach to modeling, usually requiring fewer input parameters than other models.
This study uses a screening level model to describe tritium transport for the second …

Contribution Of Recharge Along Regional Flow Paths To Discharge At Ash Meadows, Nevada, Michelle Bushman
Contribution Of Recharge Along Regional Flow Paths To Discharge At Ash Meadows, Nevada, Michelle Bushman
Theses and Dissertations
Springs in the Ash Meadows, Nevada wetland area are discharging groundwater at a high volume that cannot be sustained by local, present-day precipitation and associated recharge. Previous groundwater flow models for this region have required groundwater to flow through complex geology for long distances (160km) through fractures that, in the current stress field, should be closed in many instances in the presumed flow direction. This thesis examines several possible flow paths and evaluates each flow path using chemical and isotopic signatures in the water, as well as geologic and geophysical constraints, and determines that flow from beneath the Yucca Mountain …

A Conceptual Model Of Groundwater Flow In Spring Valley, Nv, And Snake Valley, Nv-Ut, Jeremy Micheal Gillespie
A Conceptual Model Of Groundwater Flow In Spring Valley, Nv, And Snake Valley, Nv-Ut, Jeremy Micheal Gillespie
Theses and Dissertations
A geochemical study of major springs and wells in Spring Valley, Nevada, and Snake Valley, Utah-Nevada was initiated in response to the Clark, Lincoln and White Pine Counties Groundwater Development Project proposed by the South Nevada Water Authority (SNWA). Water budget estimates suggest that interbasin flow accounts for a significant portion (~25%) of the water budgets in Spring and Snake Valleys. Although interbasin flow is possible in some areas, alternative plausible explanations place significant uncertainty on water budget allocations. To examine the plausibility of local and interbasin flow paths the groundwater flow in Spring and Snake Valleys was evaluated using …
A 700-Year History Of Groundwater Recharge In The Drylands Of Nw China, John B. Gates, W. Mike Edmunds, Jinzhu Ma, Paul R. Sheppard
A 700-Year History Of Groundwater Recharge In The Drylands Of Nw China, John B. Gates, W. Mike Edmunds, Jinzhu Ma, Paul R. Sheppard
Department of Earth and Atmospheric Sciences: Faculty Publications
A 700-year semi-quantitative history of diffuse groundwater recharge in the Badain Jaran Desert (Inner Mongolia) is proposed on the basis of solute data from multiple unsaturated zone groundwater profiles using mass balance of chloride to establish recharge rates and profile chronologies. Four relatively humid (1330–1430, 1500–1620, 1700–1780 and 1950– 1990) and three relatively arid phases (1430–1500, 1620–1700 and 1900–1950) are discernable across the profiles. The recharge history broadly reflects multidecadal to centurial timescale precipitation changes in the northern Tibetan Plateau and suggests that variations in East Asian Summer Monsoon intensity affect desert recharge rates. Uncertainties in the records owing to …

Geology Of Mammoth Cave National Park, Kentucky, Matthew M. Crawford, Rickard A. Olson, Rickard S. Toomey Iii, Lillian J. Scoggins
Map and Chart--KGS
Mammoth Cave National Park in south-central Kentucky was authorized as a national park in 1926 and was fully established in 1941 to protect the cave system, scenic landscape, and diverse flora and fauna. The park contains 52,830 acres and most of the longest recorded cave system in the world, with more than 390 miles of mapped passages as of 2013. Even though Mammoth Cave is famous, people are often unaware of the park's intricate connection to the outside region. This poster shows the geology of Mammoth Cave and the interconnected issues that are important to the park and its visitors. …
Groundwater Quality In Watersheds Of The Big Sandy River, Little Sandy River, And Tygarts Creek (Kentucky Basin Management Unit 5), R. Stephen Fisher, Bart Davidson, Peter T. Goodmann
Groundwater Quality In Watersheds Of The Big Sandy River, Little Sandy River, And Tygarts Creek (Kentucky Basin Management Unit 5), R. Stephen Fisher, Bart Davidson, Peter T. Goodmann
Report of Investigations--KGS
The Kentucky Geological Survey and the Kentucky Division of Water are evaluating groundwater quality throughout the commonwealth to determine regional conditions, assess impacts of nonpoint-source contaminants, provide a baseline for tracking changes, and provide essential information for environmental-protection and resource-management decisions. These evaluations include summarizing existing regional groundwater-quality data and reporting the results of expanded, focused groundwater collection programs in specific areas. This report summarizes groundwater sampling and analysis in Kentucky basin management unit 5 (watersheds of the Big Sandy River, Little Sandy River, and Tygarts Creek in eastern Kentucky).
Thirty wells and springs were sampled quarterly between the fall …
Characterization Of Natural Spring Waters Of The San Bernardino Mountains Using Stable Isotopes Of Oxygen And Hydrogen, Alison Renee Sloat
Characterization Of Natural Spring Waters Of The San Bernardino Mountains Using Stable Isotopes Of Oxygen And Hydrogen, Alison Renee Sloat
Theses Digitization Project
The purpose of this study was to characterize the natural spring waters of the San Bernardino Mountains using two stable isotopes. The isotopic results of this study will aid with tracing sources, movements, and mixing effects on groundwater receiving mountain-front recharge in the region.

Groundwater Contamination In Caves: Four Case Studies In Spain, Monserrat Jiménez-Sánchez, Heather Stoll, Iñaki Vadillo, Manolo López-Chicano, María Domínguez-Cuesta, Wenceslao Martín-Rosales, Mónica Meléndez-Asensio
International Journal of Speleology
Groundwater quality was monitored in four Spanish caves using concentrations of nitrate, potassium, phosphorus and in some cases total organic carbon. Three of the caves are located in NW Spain and contain prehistoric cave paintings and hence have special conservation interest. Of these, two are open show caves (Tito Bustillo and Pindal Caves), while the other one (Herrerías Cave) is not managed for tours and is partially closed off to public access. The fourth cave (Las Maravillas Cave) is located in SW Spain and is opened to the public because of its geological features and natural beauty. In this paper, …
