Modelling of electrokinetic techniques for soil remediation and ground improvement. State of the art and assessment of research opportunities
(2023)This paper presents a review of the state of the art concerning the simulation of electrokinetic techniques used in soil stabilisation and remediation processes. The main THMC models as well as those specifically ... -
Modelling a granular bentonite system as a discrete set of continuum units
(Elsevier, 2023-03)A model is proposed to describe the hydromechanical behaviour of granular bentonite systems. Its formulation is based on abstracting the system as a discrete set of bentonite units, which form continuum sub-domains where ... -
Decomposed Uncertainty Evaluation for Hydraulic State Estimation in Water Supply Systems
(American Society of Civil Engineers, 2023-04)Hydraulic state estimation (HSE) can be used to infer the flow and pressure regime in water supply systems based on the available measurements in the network and the associated hydraulic model. Because the inputs involved ... -
Simple modelling of fast hydration processes in bentonite pellet fills
(Elsevier, 2023-02)A novel hydro-mechanical formulation is presented to simulate the fast wetting of bentonite pellet fills. The model is based on a triple porosity concept, but its formulation uses a double porosity structure for simplicity. ... -
Two-Dimensional Modelling Approach for Electrokinetic Water Transport in Unsaturated Kaolinite
(MDPI, 2022-12)Although electrokinetic treatments for soil remediation and ground improvement have gradually undergone significant experimental development, one of the most important physical phenomena has received very little attention ... -
Analysis of the Mobilization of an Unsaturated Infinite Natural Slope Due to Strength Reduction
(MDPI, 2022-11)This work analyses the mobilization of infinite natural slopes that are initially partially saturated. Starting from dry conditions (the water table is assumed to be deep, far from the slope surface), the soil shear strength ... -
Potential Performance of Hydraulic State Estimation in Water Distribution Networks
(Springer, 2022-01)Hydraulic State Estimation (HSE) is a suitable tool to gain real-time understanding of water supply systems. This technique enables to estimate the most likely hydraulic behavior in the network, as well as its associated ... -
La importancia de la temperatura del agua en las redes de abastecimiento
(Universidad Politécnica de Valencia, 2022-04)La temperatura afecta a los procesos físicos, químicos y biológicos involucrados en el transporte del agua potable, por lo que condiciona la calidad del agua suministrada. Diferentes trabajos han puesto de manifiesto el ... -
The Impact of Ground Heat Capacity on DrinkingWater Temperature
(Taylor and Francis Group, 2022-12)Temperature is known to impact physical, chemical and biological processes in DrinkingWater 1Distribution Systems (DWDS), but it is rarely considered or modelled. This research evaluates the impact of considering a finite ... -
Modelización numérica 3D de la erosión local a la salida de obras de drenaje transversal
(Universidad Politécnica de Valencia, 2019-04)Las Obras de Drenaje Transversal (ODTs), frecuentes en obras lineales para recomponer la red natural de drenaje interceptada por ellas, deben ser capaces no solo de drenar el agua de su cuenca sino también de controlar la ... -
Caracterización de micro-consumos domésticos de agua potable de acuerdo con la percepción de los participantes en una iniciativa de ciencia ciudadana: la experiencia del #50lWaterChallenge

Uncertainty Evaluation for Constrained State Estimation in Water Distribution Systems
(American Society of Civil Engineers, 2016-12)In this paper, an alternative uncertainty treatment for the traditional unconstrained weighted-least-squares (WLS) method is presented. This treatment enables hydraulic constraints (i.e., null demands at transit nodes or ... -
Analytical Stochastic Microcomponent Modeling Approach to Assess Network Spatial Scale Effects in Water Supply Systems
(American Society of Civil Engineers, 2020-08)End-uses at water supply systems typically follow a random pulse behavior, which blurs as consumptions are aggregated upstream, affecting flow rate variability along the spatial scale. Instantaneous variability has impact ... -
Explicit Expressions for State Estimation Sensitivity Analysis in Water Systems
(American Society of Civil Engineers, 2018-01)The implementation of state estimation techniques to water systems enables the hydraulic state of a given network to be computed at any time. However, errors in both measurements and model parameters can severely affect ... -
