The springshed and potential recharge areas for the Downtown Salado Spring Complex, Salado, Texas.
… baseflow conditions and identified significant recharge zones by analyzing synoptic water-level maps under different aquifer conditions, collecting groundwater samples for ionic chemistry and isotopic composition analyses, and statistically correlating precipitation to changes in baseflow at …

Hydrogeophysical quantification of infiltration and recharge through soil-filled sinkholes using Time Domain Reflectometry and Electrical Resistivity Tomography
… characterizing infiltration, deep drainage, and recharge through soil-filled sinkholes. Using hydrogeophysical methods, the spatial and temporal distribution of soil moisture was modeled and potential recharge was quantified in two soil-filled sinkholes. Access-tube time domain reflectometry …

Identification of potential groundwater recharge zones: a case study of KwaZulu-Natal, South Africa
… GIS and remote sensing to demarcate groundwater potential recharge zones in the uMhlathuze catchment and Maputaland region using various pertinent parameters. The AHP approach and Catastrophe theory were used to determine acceptable zones by assigning weights to the 10parametersand their …

Anthropogenic impacts on recharge processes and water quality in basin aquifers of the desert Southwest : a coupled field observation and modeling study
… use within the Trans-Pecos basins has altered recharge mechanisms and raised questions about groundwater sustainability. Past efforts focused on recharge in arid basin systems used three main assumptions: there is minimal modern recharge, no widespread recharge on basin floors, and no recharge …

Probabilistic estimation and prediction of groundwater recharge in a semi-arid environment
Quantifying and characterizing groundwater recharge are critical for water resources management. Unfortunately, low recharge rates are difficult to resolve in dry environments, where groundwater is often most important. Motivated by such concerns, this thesis presents a new probabilistic approach …

Investigating recharge rates in Table Mountain springs using oxygen and hydrogen isotopes
… of local rainfall, estimates are made of their recharge rate. The oxygen, hydrogen, and EC data for Main spring, De Waal spring, Albion spring, and Newlands springs for the years 2013 to 2016 are presented. The oxygen and hydrogen isotope composition of monthly rainfall collected nearby at the …

Groundwater quantity and quality assessment for aquifer recharge in Ohangwena region, Namibia
… the suitability of using runoff for aquifer recharge to augment groundwater in the Ohangwena region and minimize the lowering of water table. The Geographical Information System (GIS) and groundwater flow models were used in this study to assess the water resources in the study area. A …
