A Comparative Study of Three-Dimensional Hydraulic Conductivity Upscaling at the MAcro-Dispersion Experiment (MADE) site, Columbus Air Force Base, Mississippi (USA)

Li ., Liangping; Zhou ., Haiyan; Gómez-Hernández, J. Jaime (Elsevier, 2011-07-11)

Simple averaging, simple-Laplacian, Laplacian-with-skin, and non-uniform coarsening are the techniques investigated in this comparative study of three-dimensional hydraulic conductivity upscaling. The reference is a fine ...
Contaminant source and aquifer characterization: An application of ES-MDA demonstrating the assimilation of geophysical data

Chen, Zi; Zong, Leli; Gómez-Hernández, J. Jaime; Xu, Teng; Jiang, Yuehua; Zhou, Quanping; Yang, Hai; Jia, Zhengyang; Mei, Shijia (Elsevier, 2023-11)

[EN] Contaminant source and aquifer characterization (CSAC) is critical in groundwater pollution evaluation and remediation. The ensemble smoother with multiple data assimilation (ES-MDA) is utilized to jointly identify ...
Ensemble Kalman filtering for hydraulic conductivity characterization: Parallelization and non-Gaussianity

Xu, Teng (Universitat Politècnica de València, 2014-11-03)

The ensemble Kalman filter (EnKF) is nowadays recognized as an excellent inverse method for hydraulic conductivity characterization using transient piezometric head data. and it is proved that the EnKF is computationally ...
Influence of Hydraulic Conductivity and Wellbore Design in the Fate and Transport of Nitrate in Multi-aquifer Systems

Mejía, Amanda; Cassiraga, Eduardo Fabián; Sahuquillo Herráiz, Andrés (Springer Verlag (Germany), 2012)

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 ...
Influencia de la heterogeneidad espacial de la conductividad hidráulica en modelos de agua subterránea

Carrasco Jocope, Arnold Jerson (Universitat Politècnica de València, 2021-07-01)

[EN] The management of water resources has been of great importance for several years, among which, special attention is being paid to groundwater, due to the amount of available resource and its sensitivity to natural ...

Uribe Asarta, Janire (Universitat Politècnica de València, 2019-07-31)

[ES] El Departamento de Ingeniería Civil, Ambiental, Territorial y Arquitectura (DICAteA) de la Universidad de Parma, Italia, llevó a cabo un experimento de transporte de masa empleando un tanque de plexiglás de medidas ...
Paralellized ensemble Kalman filter for hydraulic conductivity characterization

Xu, Teng; Gómez-Hernández, J. Jaime; Li ., Liangping; Zhou ., Haiyan (Elsevier, 2013-03)

[EN] The ensemble Kalman filter (EnKF) is nowadays recognized as an excellent inverse method for hydraulic conductivity characterization using transient piezometric head data. Its implementation is well suited for a parallel ...
Pattern Recognition in a Bimodal Aquifer Using the Normal-Score Ensemble Kalman Filter

Zhou, Haiyan; Li, Liangping; Hendricks Franssen, Harrie-Jan; Gómez-Hernández, J. Jaime (Springer Verlag (Germany), 2012-02)

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 ...
Stochastic analysis of three-dimensional hydraulic conductivity upscaling in a heterogeneous tropical soil

Almeida De-Godoy, Vanessa; Zuquette, L.V.; Gómez-Hernández, J. Jaime (Elsevier, 2018-08)

[EN] Hydraulic conductivity (K) heterogeneity is seldom considered in geotechnical practice for the impossibility of sampling the entire area of interest and for the difficulty of accounting for scale effects. Stochastic ...
Stochastic hydro-economic modeling for optimal management of agricultural groundwater nitrate pollution under hydraulic conductivity uncertainty

Peña Haro, Salvador; Pulido-Velazquez, M.; Llopis Albert, Carlos (Elsevier, 2011-08)

[EN] In decision-making processes, reliability and risk aversion play a decisive role. This paper presents a framework for stochastic optimization of control strategies for groundwater nitrate pollution from agriculture ...
Upscaling of water flow and mass transport in a tropical soil: numerical, laboratory and field studies

Almeida de Godoy, Vanessa (Universitat Politècnica de València, 2018-05-21)

Los modelos numéricos son herramientas fundamentales para realizar predicciones de muchos problemas enfrentados por ingenieros geotécnicos y geoambientales. Sin embargo, para que estos modelos puedan realizar predicciones ...
