In this paper, we present a conceptual-numerical model that can be deduced from a calibrated finite difference groundwater-flow model, which provides a parsimonious approach to simulate and analyze hydraulic heads and ...

[EN] The ensemble Kalman filter (EnKF) is a commonly used real-time data assimilation algorithm in various disciplines. Here, the EnKF is applied, in a hydrogeological context, to condition log-conductivity realizations ...
[EN] When linearity can be assumed (linear response of heads to stresses), stream-aquifer flow exchange can be simulated as the drainage of a number of independent linear reservoirs. This conceptual model, which can be ...
Nitrate concentrations in multi-aquifer systems are heavily affected by the presence of wellbores (active or abandoned) that are screened in several aquifers. The spatial variability of hydraulic conductivity in the confining ...
[EN] Participatory methods provide an increasingly accepted path to integrated water assessment. This research describes an interdisciplinary exercise of scenario design and modelling, which provides a methodology to couple ...
[EN] Real-time data from on-line sensors offer the possibility to update environmental simulation models in real-time. Information from on-line sensors concerning contaminant concentrations in groundwater allow for the ...
The ensemble Kalman filter (EnKF) is now widely used in diverse disciplines to estimate model parameters and update model states by integrating observed data. The EnKF is known to perform optimally only for multi-Gaussian ...

[ES] Debido al problema del uso incontrolado del agua subterránea en la agricultura, así como la introducción de agroquímicos en los cultivos, es necesario estudiar las debilidades de los acuíferos, los principales peligros ...
