A conceptual numerical model to simulate hydraulic head in aquifers that are hydraulically connected to surface water bodies

Pulido Velázquez, David; Sahuquillo Herráiz, Andrés; Andreu Álvarez, Joaquín (Wiley: 12 months, 2011-07)

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 ...
An Approach to Handling Non-Gaussianity of Parameters and State Variables in Ensemble Kalman Filtering

Zhou ., Haiyan; Gómez-Hernández, J. Jaime; Hendricks Franssen, Hendrikus Johannes W; Li, Liangping (ELSEVIER SCI LTD, 2011)

[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 ...
Efficient conceptual model for simulating the effect of aquifer heterogeneity on natural groundwater discharge to rivers

Pulido Velázquez, David; Llopis Albert, Carlos; Peña Haro, Salvador; Pulido Velázquez, Manuel Augusto (Elsevier, 2011)

[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 ...
Ensemble random forest filter: An alternative to the ensemble Kalman filter for inverse modeling

A. Godoy, Vanessa; Napa-García, Gian F.; Gómez-Hernández, J. Jaime (Elsevier, 2022-12)

[EN] The ensemble random forest filter (ERFF) is presented as an alternative to the ensemble Kalman filter (EnKF) for inverse modeling. The EnKF is a data assimilation approach that forecasts and updates parameter estimates ...
Modelación matemática del flujo de agua subterránea de los acuíferos de Requena-Utiel y Cabrillas-Malacara. Desarrollo de scripts con el uso de Python y Flopy

Corales Chauca, Andy Joel (Universitat Politècnica de València, 2022-11-24)

[ES] En la Comunidad Valencia se extiende una red extensa de masas de agua subterránea, que a través de su explotación ha permitido el desarrollo de diversas actividades productivas, sin embargo, el aprovechamiento intensivo ...
Modelación matemática del flujo de agua subterránea del acuífero de Requena Utiel. Estudio del plan de explotación de la masa de agua

Fernández Urizar, Irati (Universitat Politècnica de València, 2017-10-19)

The groundwater body Requena-Utiel is located in the central area of the Jucar Hydrographic demarcation, within the Jucar exploitation system (in 96,8%). The rest 3,2% belongs to the Túria exploitation system. It has a ...
Modelación matemática del flujo subterráneo en el dominio del Salobral‐Los Llanos (Albacete). Evolución y efectos

Rodríguez Gómez, Silvia (Universitat Politècnica de València, 2017-04-25)

Water is a basic element for life, so it must be protected and defended as such. Thus, it is necessary to inculcate a sustainable use and exploitation of water resources to keep them in a good state, both qualitative and ...
Modelo matemático del flujo de agua subterránea de los acuíferos de Requena-Utiel y Cabrillas-Malacara (Valencia)

Pérez Membrives, Miguel Ángel (Universitat Politècnica de València, 2019-10-18)

[EN] Comunidad Valenciana is a region in which a Mediterranean and dry climate predominates and in which it rains very little. Groundwater plays a very important role, since about 50% of the water consumed comes from ...
Predicción de dotaciones de bombeo en función de las condiciones climáticas del acuífero de Requena-Utiel empleando predicciones estacionales y reanálisis.

Prado Quintero, Jenny Gabriela (Universitat Politècnica de València, 2022-10-21)

[ES] La masa de agua subterránea Requena-Utiel (080.133) es la principal fuente de suministro de una de las áreas de cultivo de vid más importantes de la Comunidad Valenciana. Debido a un uso intensivo de sus recursos ...
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 ...
