Characterizing a VOC Plume Migrating From Fractured Shale into a Karst Limestone Aquifer
ABSTRACT: Delineation of the NAPL source zone in the vicinity of an oil burn pit (OBP) at Letterkenny Army Depot (LEAD) revealed the presence of source material on both sides of a nearby groundwater divide resulting in a bilobate plume. While the northern lobe of the plume migrating from the OBP had been well defined, the southern lobe of the plume had been previously undetected. An investigati...
متن کاملKarst 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 کاملCross - borehole slug test analysis in a fractured limestone aquifer
This work proposes new semi-analytical solutions for the interpretation of cross-borehole slug tests in fractured media. Our model is an extension of a previous work by Barker (1988) and Butler and Zhan (2004). It includes inertial effects at both test and observation wells and a fractional flow dimension in the aquifer. The model has 5 fitting parameters: flow dimension n, hydraulic conductivi...
متن کاملElastic waves in fractured rocks under periodic compression
Background: One of the current problems in studying the mechanical properties and behavior of structurally inhomogeneous media with cracks is the characterization of acoustic wave propagation. This is especially important in Geomechanics and prognosis of earthquakes. Methods: In this work, the authors propose an approach that could simplify characterization of wave propagation in medium with cr...
متن کاملParticle-tracking simulations of anomalous transport in hierarchically fractured rocks
Complex topology of fracture networks and interactions between transport processes in a fracture and the ambient un-fractured rock (matrix) combine to render modeling solute transport in fractured media a challenge. Classical approaches rely on both strong assumptions of either limited or full diffusion of solutes in the matrix and simplified fracture configurations. We analyze fracture-matrix ...
