Regional flow conditions associated with stratocumulus cloud-clearing events over the southeast Atlantic
… to be excited by an interaction between offshore flow from the African continent and the stratocumulus-topped marine boundary layer. The Weather Research and Forecasting (WRF) model is used to explore the nature of the offshore flow, which is a fundamental physical mechanism behind the dramatic …

Contribution of Recharge Along Regional Flow Paths to Discharge at Ash Meadows, Nevada
… 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 …

Cardiovascular function in animal models of metabolic syndrome and type 2 diabetes : the role of inducible nitric oxide synthase (iNOS)
… pressure, cardiac contractility, cardiac index, regional flow, vascular resistance and venous tone were measured in diseased as well as normal rats. Biochemical analyses such as activities of iNOS, immunostaining of iNOS and western-blot analysis of iNOS in the heart tissue were carried out. The …

ΑΣΤΑΘΗΣ ΡΟΗ ΣΕ ΚΑΡΣΤΙΚΑ ΥΔΡΟΦΟΡΑ ΣΤΡΩΜΑΤΑ ΜΕ ΤΗ ΜΕΘΟΔΟ ΤΩΝ ΠΕΠΕΡΑΣΜΕΝΩΝ ΣΤΟΙΧΕΙΩΝ
THE GROUNDWATER FLOW IN A CONFINED KARST AQUIFER IS STUDIED BY THE MODEL OF DOUBLE POROSITY. THIS IS A CONTINUOUS MODEL BUT IT TAKES INTO ACCOUNT THE HETEROGENEITY OF POROUS MEDIA. IT IS ALSO ASSUMED THAT IN KARST AQUIFERS THE FLOW CAN BE BEYOND THE UPPER LIMIT OF THE VALIDITY OF DARCY'S LAW. THE …

Geochemical interpretation on groundwater flow in the Southern Great Basin
… of geochemical processes and integrated water flow can help identify groundwater sources and improve predictions of contaminant fate and transport in groundwater systems. Understanding groundwater flow paths in and around the Nevada Test Site (NTS) is important due to the possible migration of …

Surface Effects of Ground Water Flow Patterns - Bottineau and Mountrail Counties, North Dakota
<p>In the resolution of patterns of groundwater flow, certain surface expression is noted as being helpful. Vegetation has been used in other areas as an indicator of the chemistry of groundwater, but this type of exploration may be expanded to include physiography as well as vegetation. </p><p>The …

Modeling the Impacts of Land Use Activities on the Subsurface Flow Regime of the Upper Roanoke River Watershed
… impact of land use activities on the subsurface flow regime in the Upper Roanoke River Watershed in Virginia to determine the impacts of land use change on the subsurface flow system, and to provide a tool for future management decisions. Land use activities can impact the groundwater system in …

Depositional history and diagenesis of the upper Mission Canyon and lower Charles Formations (Mississippian), Billings County, North Dakota
… of a freshwater influx possibly as a result of regional flow through the Madison aquifer. </p><p>Eogenetic dolomitization of sublittoral deposits, which was the most prominent diagenetic process, took place through an evaporative reflux mechanism. Minor eogenetic dolomitization of littoral and …

Paleogeothermal Conditions in the Illinois Basin During Late Paleozoic Coalification
… observations suggest that topographically driven regional flow of hydrothermal fluids through the Upper Paleozoic Lower Paleozoic aquifers raised the temperature and caused an inflection(s) found in the paleogeotherms. The purpose of this dissertation was to; characterize the paleogeothermal …

Groundwater flow, hydrochemistry, and uranium deposition in the Powder River Basin, Wyoming
<p>The relation between regional groundwater flow, hydrochemistry, and uranium distribution in the Powder River Basin indicates that uranium was deposited during the Tertiary Period in groundwater recharge areas where the groundwater changed from a sulfate-bicarbonate water to a bicarbonate-rich …

Assessment of river-groundwater interactions in the Barotse floodplain, Western Zambia.
… package was used to determine the Base Flow Index (BFI) from the hydrograph discharge data collected from the three main gauging stations (Lukulu, Matongo and Senanga) along the Zambezi River. Hydrochemistry was employed to determine the composition of the different water sources and …
