Refinement indicators for estimating hydrogeologic parameters

open access: yes, 2016
We identify simultaneously the hydraulic transmissivity and the storage coefficient in a ground water flow governed by a linearparabolic equation. Both coefficients are assumed to be functions which are piecewise constant in space and constant in time.Therefore the unknowns are the coefficient values as well as the geometry of the zones where these ...

Exploring copepod distribution patterns at three nested spatial scales in a spring system. Habitat partitioning and potential for hydrological bioindication [PDF]

open access: yes, 2015
In groundwater-fed springs, habitat characteristics are primarily determined by a complex combination of geomorphic features and physico-chemical parameters, while species assemblages are even more intricate.

3D attributed models for addressing environmental and engineering geoscience problems in areas of urban regeneration : a case study in Glasgow, UK [PDF]

open access: yes, 2007
The City of Glasgow is situated on and around the lower floodplain and inner estuary of the River Clyde in the west of Scotland, UK. Glasgow’s urban hinterland once was one of Europe’s leading centres of heavy industry, and of ship building in particular.

Identification of high-permeability subsurface structures with multiple point geostatistics and normal score ensemble Kalman filter [PDF]

open access: yes, 2017
Alluvial aquifers are often characterized by the presence of braided high-permeable paleo-riverbeds, which constitute an interconnected preferential flow network whose localization is of fundamental importance to predict flow and transport dynamics ...
