Karst Aquifer Recharge: Comments on Somaratne, N. Characteristics of Point Recharge in Karst Aquifers.
The article “Characteristics of Point Recharge in Karst Aquifers, Water 6: 2782–2807” by N. Somaratne evaluates various recharge estimation techniques applied to four limestone aquifers in South Australia. Somaratne [1] concludes that methods based on watertable fluctuations, groundwater modelling and water budgets are independent of recharge processes, and are therefore superior to the chlorid...
متن کاملTransmissivity of Aquifer by Capture Zone Method: An Application in the Sete Lagoas Karst Aquifer, MG, Brazil.
Transmissivity is an important hydraulic parameter to determine the amount of water passed horizontally across a given saturated thickness of an aquifer. The techniques to quantify this parameter, such as grain size analyses or pumping tests, can have limitations of time/spatial scale, viability, or economically. One technique that can be used, but little adopted, is the capture zone analysis. ...
متن کاملHydrothermal waters from karst aquifer: Case study of the Trozza basin (Central Tunisia)
Tunisia is rich in geothermal resources from ancient civilizations. Hydrothermal activity in Tunisia has been related to three main stages: magmatic and tectonic activities, eustatisme (Atlantic and Mediterranean coupling) and climate change. The principal factor and the responsable of this phenomenon is the meteoric water by piston flow processes. It constitue the catalyst of volcanism. The Tr...
متن کاملVADOCHARGE: Groundwater Recharge Model for an Uplifted Island Karst Aquifer, Guam, USA
The Northern Guam Lens Aquifer (NGLA) presents unique challenges to modelers due to the complex hydrologic properties of its thick karst vadose zone. To meet these challenges, we developed VADOCHARGE, an analogue model based on the US Army Corps of Engineers’ Streamflow Synthesis and Reservoir Regulation (SSARR) model, to produce the effect of attenuated and lagged recharge through the vadose z...
متن کاملOn the Coupled Continuum Pipe Flow Model (ccpf) for Flows in Karst Aquifer
We show that the coupled continuum pipe flow model (CCPF) for flows in karst aquifers is ill-posed in the sense that no reasonable solution exists. We also demonstrate that Hua’s modified CCPF model is ill-posed in 3D although it is well-posed in two spatial dimensions. A new modification of the original CCPF model that is consistent with basic physics is proposed and its well-posedness is prov...
