Remotely sensed evapotranspiration (ET) rates can provide an additional constraint on the calibration of groundwater models beyond typically-used water table (WT) level observations. The value this constraint, measured in terms reductions model error, however, is expected to vary with method by which it imposed and how closely ET flux dependant levels. To investigate variability, four silvicult...

C. Sanz de Galdeano Instituto Andaluz de Ciencias de la Tierra (C.S.I.C., Universidad de Granada), Facultad de Ciencias, E-18071 Granada, Spain Abstract The analysis of the fractures in the marble forming sierras Blanca and Mijas (southern Spain), with faults of markedly different sizes and joints measured at 21 stations, demonstrate the presence of two principal directions of fractures (NNW-SS...

In 2010–2012, scientists of Riga technical University have developed the hydrogeological model of Latvia (LAMO). In 2013, LAMO has been applied as a tool to implement in Latvia aims laid down by the European Union Water Framework Directive for sustainable use of water resources. The set of hydrogeological maps was prepared for updating of the water management plans for the river basin districts...

Ž . Ž . Four-dimensional 4D or time-lapse three-dimensional 3D ground penetrating radar surveys can be used to monitor and image subsurface fluid flow. This information can be used to create a model of hydrogeological properties. The massive amount of data, which is present in and can possibly be generated from 4D GPR data sets, precludes a manual interpretation. Consequently, 4D data sets have...

In this paper, the Artificial Neural Network (ANN) approach is applied for forecasting groundwater level fluctuation in Aghili plain,southwest Iran. An optimal design is completed for the two hidden layers with four different algorithms: gradient descent withmomentum (GDM), levenberg marquardt (LM), resilient back propagation (RP), and scaled conjugate gradient (SCG). Rain,evaporation, relative...
