An evaluation of semidistributed-pipe-network and distributed-finite-difference models to simulate karst systems
Published in Hydrogeology Journal
Several different approaches have been developed to model the specific characteristics of karst aquifers, taking account of their inherent complex spatial and temporal heterogeneities. This paper sets out the development of a semidistributed modelling approach for applications in an Irish karst context using urban drainage software. The models have...
Groundwater circulation and earthquake-related changes in hydrogeological karst environments: a case study of the Sibill...
Published in Hydrogeology Journal
Using artificial tracer tests, this study confirms the presence of a single basal aquifer feeding the springs in the wide and complex hydrogeological boundary of the Sibillini Mountains of central Italy. The tracer was introduced into the sinkhole of the Castelluccio di Norcia plain. The tracer test results, observed at the studied springs, highlig...
Hydrogeological characterization of an alpine aquifer system in the Canadian Rocky Mountains
Published in Hydrogeology Journal
Groundwater storage in alpine regions is essential for maintaining baseflows in mountain streams. Recent studies have shown that common alpine landforms (e.g., talus and moraine) have substantial groundwater storage capacity, but the hydrogeological connectivity between individual landforms has not been understood. This study characterizes the hydr...
Hydrochemical and environmental isotopes analysis for characterizing a complex karst hydrogeological system of Watuputih...
Published in Hydrogeology Journal
The karst hydrogeology systems of the Watuputih Hills region of Central Java, Indonesia, have many springs with varying discharge and are composed of formations with complex geological structures. This work characterized the karst hydrogeology by studying 50 hydrogeological features (caves, springs and wells) and by analyzing the chemical-physical ...
A combined-method approach to trace submarine groundwater discharge from a coastal karst aquifer in Ireland
Published in Hydrogeology Journal
Knowledge about the hydraulic connections between submarine groundwater discharge (SGD) and its terrestrial coastal catchment is relevant with regard to the management of marine and coastal waters in karst areas. This study applies different methods and monitoring approaches to trace SGD between the Burren Limestone Plateau and Galway Bay in wester...
Impact of river reconstruction on groundwater flow during bank filtration assessed by transient three-dimensional modell...
Published in Hydrogeology Journal
Bank filtration (BF) is an established indirect water-treatment technology. The quality of water gained via BF depends on the subsurface capture zone, the mixing ratio (river water versus ambient groundwater), spatial and temporal distribution of subsurface travel times, and subsurface temperature patterns. Surface-water infiltration into the adjac...

Integrated hydrogeological modelling of hard-rock semi-arid terrain: supporting sustainable agricultural groundwater use...
Published in Hydrogeology Journal
An integrated hydrogeological modelling approach applicable to hard-rock aquifers in semi-arid data-scarce Africa was developed using remote sensing, rainfall-runoff modelling, and a three-dimensional (3D) dynamic model. The integrated modelling approach was applied to the Hout catchment, Limpopo Province, South Africa, an important agricultural re...
Groundwater occurrence in the Sakumo wetland catchment, Ghana: model–setting–scenario approach
Published in Hydrogeology Journal
Water flow is required for the health and integrity of any wetland environment. Based on field investigation, flow simulation and hydrogeological data, a conceptual flow model representing the physical characteristics of the Sakumo wetland (Ghana) was developed. Two major flow systems were identified: interflow (local topsoil water) in the alluvium...
