Assessment of Groundwater Recharge Using WetSpass-M and MODFLOW Coupling in Jedeb Watershed, Upper Blue Nile Basin, Ethiopia

open access: yesAir, Soil and Water Research
Currently, the demand for water is rising, and as a result, the groundwater is declining. Water supplies are not sufficient for agricultural productivity, environmental preservation, or ecosystem services, resulting in an unbalanced water budget in the ...

Accurate and efficient calculation of response times for groundwater flow

open access: yes, 2018
We study measures of the amount of time required for transient flow in heterogeneous porous media to effectively reach steady state, also known as the response time. Here, we develop a new approach that extends the concept of mean action time.

Numerical modelling in support of a conceptual model for groundwater flow and geochemical evolution in the southern Outaouais Region, Quebec, Canada [PDF]

open access: yes, 2017
A two-dimensional vertical-section numerical model for groundwater flow and transport using age, tritium and chloride was used to help validate a conceptual model of geochemical evolution within a representative regional-scale hydrogeological system in ...

Artificial recharge of groundwater in The Netherlands

open access: yesWater Practice and Technology, 2007
After a short general overview of the Dutch drinking water industry, the artificial recharge projects run by three drinking water companies situated in the West of The Netherlands are described in some detail. Because all the other groundwater in this part of the country is brackish, fresh groundwater from the sandy dunes along the coast has been ...

A Process Based Modeling Approach to Assess Temperature Impacts of Riparian Vegetation Management in a Southwestern Wisconsin Trout Stream

open access: yesRiver Research and Applications, EarlyView.
ABSTRACT Rising water temperatures driven by climate change threaten culturally and economically important salmonid fisheries throughout the Upper Midwest. Unsuitable thermal regimes degrade the effectiveness of habitat restoration projects in the region, thus strategies for mitigating peak summer stream temperatures are of interest to state and non ...

Estimating natural groundwater recharge taking into consideration temporal and spatial variability for arid unconfined aquifer

open access: yesWater Science
Water scarcity is one of the major critical affecting arid climate countries. In addition, population growth and climate change are threatening the sustainable development of water resources in the upcoming decades.

Impact of recent climate variability on an aquifer system in north Belgium [PDF]

open access: yes, 2012
The last decade it has been realised that climate and global change can (and very likely will affect) groundwater reserves. This will have impact on both the economical (groundwater exploitation) and ecological (ecosystems) aspects of aquifer systems.

Artificial recharge – measurement of soil infiltration in Rožnov pod Radhoštěm [PDF]

open access: yes, 2017
The purpose of this study is to evaluate the potential for infiltration in a study area – Rožnov pod Radhoštěm, the Czech Republic. The results are important for the future design of an artificial recharge structure as a method to store water underground

Determining Regional-Scale Groundwater Recharge with GRACE and GLDAS

open access: yesRemote Sensing, 2019
Groundwater recharge (GR) is a key component of regional and global water cycles and is a critical flux for water resource management. However, recharge estimates are difficult to obtain at regional scales due to the lack of an accurate measurement ...
