“…Overviews of ready-made model packages for GW-SW (primarily addressing loosely coupled schemes) have been compiled by CDM (2001), Blum et al (2002), Levy and Xu (2012), Bobba (2012), Alaghmand et al (2013), and Sebben et al (2013). These overviews, however, do not directly address applicability or applications at the regional scale.…”

Scientists and practitioners agree that integrated water resource management is necessary, with an increasing need for research at the regional scale (10 3 to 10 5 km 2 ). At this scale interactions between environmental and human systems are fully developed and global change is linked to local actions. The groundwater-surface water interaction (GW-SW) is of particular interest. Herein we review the scientific journal literature and examine GW-SW at the regional scale. We briefly review all existing literature on GW-SW, then summarise its characteristics at different scales and identify specific challenges of the regional scale. We explore whether GW-SW should be treated differently at regional and local scales. Regional GW-SW is rarely examined in experimental field studies, which almost exclusively cover small areas. However, GW-SW is often integral to large scale coupled models. Thus, we collate information about existing models and their regional applications. Fully coupled, physics-based models have great potential to meet the technical challenges. However, limited data availability hampers the application of complex models at the regional scale and loosely coupled schemes are more widely applied. Many integrated modelling concepts have been published, but none have been applied in a wide range of settings. Thus, it is impossible to compare the performance of different approaches. Comparative analyses of existing regional scale integrated models in the context of different data availability and geographic conditions are needed. Unfortunately, peer-reviewed journal literature no longer provides a representative picture of the subject as models are becoming Btoo big to be published^or too pragmatic.

“…Also, MIKE‐SHE and FEFLOW have been coupled with MIKE11 to address management‐based questions at a regional scale (Barthel & Banzhaf, , also found commonly linked in our study). Other authors have overviewed packages for modelling groundwater–surface water interactions (Alaghmand, Beecham, & Hassanli, ; Bobba, ; Levy & Xu, ; Sebben, Werner, Liggett, Partington, & Simmons, ).…”

Synthesizing models useful for ecohydrology and ecohydraulic approaches: An emphasis on integrating models to address complex research questions

et al. 2018

Ecohydrology combines empiricism, data analytics, and the integration of models to characterize linkages between ecological and hydrological processes. A challenge for practitioners is determining which models best generalizes heterogeneity in hydrological behaviour, including water fluxes across spatial and temporal scales, integrating environmental and socio‐economic activities to determine best watershed management practices and data requirements. We conducted a literature review and synthesis of hydrologic, hydraulic, water quality, and ecological models designed for solving interdisciplinary questions. We reviewed 1,275 papers and identified 178 models that have the capacity to answer an array of research questions about ecohydrology or ecohydraulics. Of these models, 43 were commonly applied due to their versatility, accessibility, user‐friendliness, and excellent user‐support. Forty‐one of 43 reviewed models were linked to at least 1 other model especially: Water Quality Analysis Simulation Program (linked to 21 other models), Soil and Water Assessment Tool (19), and Hydrologic Engineering Center's River Analysis System (15). However, model integration was still relatively infrequent. There was substantial variation in model applications, possibly an artefact of the regional focus of research questions, simplicity of use, quality of user‐support efforts, or a limited understanding of model applicability. Simply increasing the interoperability of model platforms, transformation of models to user‐friendly forms, increasing user‐support, defining the reliability and risk associated with model results, and increasing awareness of model applicability may promote increased use of models across subdisciplines. Nonetheless, the current availability of models allows an array of interdisciplinary questions to be addressed, and model choice relates to several factors including research objective, model complexity, ability to link to other models, and interface choice.

“…For instance, capillary rise of salt driven by shallow saline groundwater could cause salinization of root zones and further decline in plant productivity (Kobryn et al, 2015). Comparably, groundwater salinization is a more severe problem in arid and semi-arid regions where the groundwater plays an essential role in supporting ecosystems and providing invaluable water resource (Alaghmand et al, 2013;Jones et al, 2009). In the southwest Australia, Caccetta et al (2010) evaluated that the land salinity driven by saline groundwater has covered almost one million hectares of land in 1996 and a further 5.4 million hectares are at risk of future salinization.…”
