“…Soil parameterization is based on the DK‐models as presented earlier (Henriksen et al ., ). This model is inversely calibrated under stationary conditions using hydraulic head observations as well as stream runoff data as target data (from outside of the modelled domain).…”

Infiltration of groundwater to sewer systems is a problem for the capacity of the system as well as for treatment processes at waste water treatment plants. This paper quantifies the infiltration of groundwater to a sewer system in Frederikshavn Municipality, Denmark, by measurements of sewer flow and novel model set‐up, which simulates the interaction between groundwater and sewer flow. The study area has a separate waste water sewer system, but the discharged volumes from the system are approximately twice the volumes from a tight system without infiltration. The model set‐up makes use of two commercial models: mike she for simulation of groundwater transport and mike urban (mouse) [DHI, Hørsholm, Denmark] for simulation of sewer flow. By simulating the groundwater level and calibrating infiltration coefficients against sewer flow measurements, it has been possible to estimate the average infiltration to the sewer system with satisfying results. The infiltration processes are indeed complicated and to a large degree heterogeneous throughout the sewer system. The paper shows contribution from both saturated and unsaturated groundwater zones, which makes the modelling process complex. Copyright © 2016 John Wiley & Sons, Ltd.

“…Due to the long-term effects recharge is likely to have on water quality, ecology and socioeconomic factors, it remains important in assessment of sustainability (Henriksen et al, 2007). As a result, efforts should be made to estimate recharge rates and other relevant exchange flow components of a groundwater body.…”

“…Because recharge affects water quality, ecology and socio-economic factors, these factors should be considered in sustainability assessments (Henriksen et al 2008b). Therefore, efforts should be made to estimate recharge rates and other flow exchange components, such as surface water-groundwater interactions and groundwater abstractions, of a groundwater body (Henriksen et al 2008a).…”

A holistic approach to groundwater sustainability considers the hydrological, ecological, socio-economic and technological aspects of groundwater utilization. Exploitable groundwater should be determined by physical analysis, as well as by social compromises within a community. In this work, an integrated surface water-groundwater model, SWAT-MODFLOW, is used to examine changes in hydrological components due to various groundwater pumping scenarios in the Mihocheon watershed of South Korea. Under a total groundwater abstraction of 104 mm, which is slightly less than the amount currently permissible by law, a change in storage levels of -16 mm occurred. This abstraction value, which corresponds to 33% of the annual recharge, may be an exploitable groundwater reserve available to Cheongju City, Korea.Estimation de la quantité d'eau souterraine exploitable en utilisant un modèle intégré surfacesouterrain: bassin versant de Mihocheon, Corée du Sud Résumé En tant qu'approche holistique des eaux souterraines, la durabilité considère les aspects hydrologiques, écologiques, socio-économiques et technologiques de l'utilisation des eaux souterraines. La quantité d'eau souterraine exploitable devrait être déterminée par l'analyse physique autant que par des compromis sociaux au sein d'une communauté. Dans ce travail, un modèle intégré eau de surface-eau souterraine, SWAT-MODFLOW, a été utilisé pour examiner les changements des composantes hydrologiques résultant de divers scénarios de pompage des eaux souterraines dans le bassin versant de Mihocheon, en Corée du Sud. Avec un pompage total d'eau souterraine de 104 mm, ce qui est légèrement inférieur au montant actuellement autorisé par la loi, on observe une de niveau de -16 mm. Cette valeur de pompage, qui correspond à 33% de la recharge annuelle, pourrait constituer une réserve d'eau souterraine exploitable disponible pour la ville de Cheongju.
