The nomenclature for Kansas aquifers needs revision. Many of the names currently in use were derived in an ad hoc manner without the benefit of a consistent set of hydrogeologically based guidelines. Because nomenclature forms the basis of scientific discussion of hydrologic issues, names should be clearly defined and consistently applied in order to prevent erroneous or unintended hydrologic i...

50 A groundwater investigation including several pumping tests has been carried out by 51 Thames Water Utilities Limited (TWUL) to improve the understanding of the 52 distribution of hydraulic properties of the Chalk in the Swanscombe area of Kent in 53 south-eastern England. The pumping test behaviour is complicated by: the fractured 54 condition of the Chalk, simultaneous pumping from adjacen...

Analyses of areal variations in the subsidence and rebound occurring over stressed aquifer systems, in conjunction with measurements of the hydraulic head fluctuations causing these displacements, can yield valuable information about the compressibility and storage properties of the aquifer system. Historically, stress-strain relationships have been derived from paired extensometer/piezometer i...

In this work is presented a general architecture for a multi physical agent network system based on the coordination and the behaviour management. The system is organised in a hierarchical structure where are distinguished the individual agent actions and the collective ones linked to the whole agent network. Individual actions are also organised in a hybrid layered system that take advantages ...

Inter-aquifer water exchange between the shallow and Memphis aquifers in Shelby County, Tennessee may pose a contamination threat due to downward migration of younger, poor quality groundwater into deeper, more pristine aquifer. Discontinuities (breaches) upper Claiborne confining unit (UCCU) allow for leakage aquifer, sand-dominated aquifer that provides about 95% used area. This study created...

Most of the Mediterranean coastal porous aquifers are intensively exploited. Because of climatic and anthropogenic effects, understanding the physical and geological controls on groundwater distribution and flow dynamics in such aquifers is crucial. This study presents the results of a structural investigation of a system located along the coastline of the Gulf of Lions (NW Mediterranean). A ke...

In the field of genetic research and the subsequent rise of biobanks an intensive discussion is taking place on national and international levels about property and personality rights to one’s own body and body parts. The authors attempt to develop on the basis of the current controversially discussed law a concept of property, which can solve the legal and bioethical problems of the multiple u...

This paper presents an analytical solution to describe tidal groundwater level fluctuations in a coastal leaky aquifer system bounded by water–land boundaries that form a right angle (referred to as L-shaped coastlines). The system consists of an unconfined aquifer, a confined aquifer and a leaky layer between them. Previously published analytical solutions that discuss only single aquifer cons...

Groundwater age distributions are used to estimate the parameters of Fickian, and non-Fickian, effective models of solute transport. Based on the similarities between the transport and age equations, we develop a deconvolution based approach that describes transport between two monitoring wells. We show that the proposed method gives exact estimates of the travel time distribution between two w...
