What are the main factors influencing the presence of faecal bacteria pollution in groundwater systems in developing countries?
(2020-01)
Article
Restricted access - publisher's policyGroundwater is the major source of drinking water in most rural areas in developing countries. This resource is threatened by the potential presence of faecal bacteria coming from a variety of sources and pollution paths, ... -
How does water-reliant industry affect groundwater systems in coastal Kenya?
(Elsevier, 2019-12)
Article
Open AccessThe industrialization process taking place in Africa has led to an overall increase in groundwater abstraction in most countries in the continent. However, the lack of hydrogeological data, as in many developing countries, ... -
Groundwater hydrodynamics of an Eastern Africa coastal aquifer, including La Niña 2016–17 drought
(Elsevier, 2019-04-15)
Article
Restricted access - publisher's policyIn 2016–17 much of East Africa was affected by a severe drought which has been attributed to Indian Ocean Dipole and El Niño Southern Oscillation conditions. Extreme events such as this have immediate and knock-on effects ... -
Numerical equivalence between SPH and probabilistic mass transfer methods for Lagrangian simulation of dispersion
(Elsevier, 2019-04)
Article
Restricted access - publisher's policySeveral Lagrangian methodologies have been proposed in recent years to simulate advection-dispersion of solutes in fluids as a mass exchange between numerical particles carrying the fluid. In this paper, we unify these ... -
AkvaGIS: an open source tool for water quantity and quality management
(2019-06)
Article
Open AccessAkvaGIS is a novel, free and open source module included in the FREEWAT plugin for QGIS that supplies a standardized and easy-to-use workflow for the storage, management, visualization and analysis of hydrochemical and ... -
A bilayer coarse-fine infiltration system minimizes bioclogging: the relevance of depth-dynamics
(Elsevier, 2019-06)
Article
Restricted access - publisher's policyBioclogging is a main concern in infiltration systems as it may significantly shorten the service life of these low-technology water treatment methods. In porous media, biofilms grow to clog partially or totally the pore ... -
Are dominant microbial sub-surface communities affected by water quality and soil characteristics?
(2019-05)
Article
Restricted access - publisher's policySubsurface microorganisms must deal with quite extreme environmental conditions. The lack of light, oxygen, and potentially nutrients are the main environmental stresses faced by subsurface microbial communities. Likewise, ... -
A simple contaminant fate and transport modelling tool for management and risk assessment of groundwater pollution from contaminated sites
(2019-02)
Article
Restricted access - publisher's policyContaminated sites pose a significant threat to groundwater resources. The resources that can be allocated by water regulators for site investigation and cleanup are limited compared to the large number of contaminated ... -
Microbial community changes induced by Managed Aquifer Recharge activities: linking hydrogeological and biological processes
(2019-01)
Article
Open AccessManaged Aquifer Recharge (MAR) is a technique used worldwide to increase the availability of water resources. We study how MAR modifies microbial ecosystems and its implications for enhancing biodegradation processes to ... -
The value of satellite remote sensing soil moisture data and the DISPATCH algorithm in irrigation fields
(2018-11)
Article
Open AccessSoil moisture measurements are needed in a large number of applications such as hydro-climate approaches, watershed water balance management and irrigation scheduling. Nowadays, different kinds of methodologies exist for ... -
Lagrangian modeling of reactive transport in heterogeneous porous media with an automatic locally adaptive particle support volume
(2018-10)
Article
Open AccessThe particle support volume is crucial for simulating reactive transport with Lagrangian methods as it dictates the interaction among particles. Assuming that it is constant in space, the particle support volume can be ... -
Generalizing Agarwal's method for the interpretation of recovery tests under non-ideal conditions
(2018-09)
Article
Open AccessPumping tests are performed during aquifer characterization to gain conceptual understanding about the system through diagnostic plots and to estimate hydraulic properties. Recovery tests consist of measuring head response ...
