Hydraulic properties of a major alluvial aquifer: An isotropic, inhomogeneous system

Groundwater flow modelling in the central zone of Hanoi, Vietnam

“…This tool is constructed on the basis of a comprehensive sedimentological model (Jusseret, S., Université de Liège, Université Catholique de Louvain; Baeteman, C., Belgian Geological Survey; Dassargues, A., Université de Liège, Katholieke Universiteit Leuven; "The stratigraphical architecture of the Quaternary deposits as support for hydrogeological modelling of the central area of Hanoi (Vietnam) ", unpublished report, 2008). Similar works linking sedimentological modelling with hydrogeological purposes in unconsolidated sediments are presented by Bonomi (2009), Foreman and Sharp (1981), Hanson et al (2002Hanson et al ( , 2003Hanson et al ( , 2004, Huggenberger and Regli (2006), McMahon et al (2000), Ponti et al (2007), Faunt et al (2008), Sharpe et al (2003) and Yong et al (1995).…”

“…The combination of the sedimentological data (Jusseret et al, as previously given, "The stratigraphical architecture of the Quaternary deposits as support for hydrogeological modelling of the central area of Hanoi (Vietnam)", unpublished report, 2008) and the results of pumping tests are particularly useful to estimate the parameter values and spatial distribution of hydrogeological units (see Fogg et al 1998;Foreman andSharp 1981 andMcCloskey andFinnemore 1996 for similar approaches).

A numerical modelling and neural network approach to estimate the impact of groundwater abstractions on river flows

“…The experiments were carried out whilst the stream was dry, water being pumped down the channel and flow losses between predetermined points measured. Typical values for valley gravel aquifer transmissivities were found in the literature (Foreman and Sharp, 1981) and an average transmissivity of 4000 m 2 /day was used in the model. The specific yield of the valley gravel was taken as 0.25 (Freeze and Cherry, 1979).…”

Ground-water flow and ground- and surface-water interaction at McBaine Bottoms, Columbia, Missouri-2000-02

“…Ground-water flow generally was north to south within McBaine Bottoms and nearly parallel to the flow of the Missouri River. Foreman and Sharp (1981) used river altitude and water-level data, aquifer test analyses, and threedimensional simulations to investigate the hydrologic properties of the alluvial aquifer in McBaine Bottoms. Ground-water levels were primarily controlled by the altitude of the Missouri River and quantity of water pumped from the aquifer.…”

“…Water levels changed somewhat in the watertable map of August 1978 compared to those in 1968 ( fig. 33; Foreman and Sharp, 1981). In addition to water levels from the wells that were measured for the July 1968 water-table map, water levels from shallow wells that were installed in 1978 were included.…”
