“…Former applications used a fixed water level throughout the simulation period (Arnold et al, 1999;Chung et al, 2010;Flipo et al, 2007b;Gomez et al, 2003;Ke, 2014;Kim et al, 2008;Monteil, 2011;Perkins and Sophocleous, 1999;Ramireddygari et al, 2000;Thierion et al, 2012). Saleh et al (2011) showed that this methodology not only leads to biased assessments of streamaquifer exchanges, but also to biased estimates of the nearriver piezometric head distributions.…”

Abstract. Coupled hydrological-hydrogeological models, emphasising the importance of the stream-aquifer interface, are more and more used in hydrological sciences for pluridisciplinary studies aiming at investigating environmental issues. Based on an extensive literature review, stream-aquifer interfaces are described at five different scales: local [10 cm- . This led us to develop the concept of nested stream-aquifer interfaces, which extends the well-known vision of nested groundwater pathways towards the surface, where the mixing of low frequency processes and high frequency processes coupled with the complexity of geomorphological features and heterogeneities creates hydrological spiralling. This conceptual framework allows the identification of a hierarchical order of the multi-scale control factors of stream-aquifer hydrological exchanges, from the larger scale to the finer scale. The hyporheic corridor, which couples the river to its 3-D hyporheic zone, is then identified as the key component for scaling hydrological processes occurring at the interface. The identification of the hyporheic corridor as the support of the hydrological processes scaling is an important step for the development of regional studies, which is one of the main concerns for water practitioners and resources managers.In a second part, the modelling of the stream-aquifer interface at various scales is investigated with the help of the conductance model. Although the usage of the temperature as a tracer of the flow is a robust method for the assessment of stream-aquifer exchanges at the local scale, there is a crucial need to develop innovative methodologies for assessing stream-aquifer exchanges at the regional scale. After formulating the conductance model at the regional and intermediate scales, we address this challenging issue with the development of an iterative modelling methodology, which ensures the consistency of stream-aquifer exchanges between the intermediate and regional scales.Finally, practical recommendations are provided for the study of the interface using the innovative methodology MIM (Measurements-Interpolation-Modelling), which is graphically developed, scaling in space the three pools of methods needed to fully understand stream-aquifer interfaces at various scales. In the MIM space, stream-aquifer interfaces that can be studied by a given approach are localised. The efficiency of the method is demonstrated with two examples. The first one proposes an upscaling framework, structured around river reaches of ∼ 10-100 m, from the local to the watershed scale. The second example highlights the usefulness of space borne data to improve the assessment of streamaquifer exchanges at the regional and continental scales. We conclude that further developments in modelling and field measurements have to be undertaken at the regional scale to enable a proper modelling of stream-aquifer exchanges from the local to the continental scale.

“…This combined modeling was applied to the Musimcheon basin in Korea by Kim et al (2008). Chung et al (2010) applied this method to the Mihocheon watershed in South Korea, estimated spatio-temporal groundwater recharge distribution. Their modeling results demonstrated that annual average recharge rates should be estimated by long-term continuous simulations using a distributed hydrologic modeling technique.…”

One of the most essential groundwater model components is accurate information about the recharge values within the input data, often introduced to a groundwater model as a percentage of rainfall on aquifers. Recharge values are influenced by many temporal and spatial factors. This paper suggests the use of a SWAT model for surface water simulation and the estimation of recharge rates. In this research, sensitivity analysis, calibration, validation and uncertainty analysis of results were performed by SWAT-CUP software. Due to the semi-distributed features of SWAT and the difficulty of calculating groundwater distributed parameters, recharge values estimated by SWAT were used in a MODFLOW model for groundwater simulation at steady and unsteady states. This method was applied in the Firoozabad basin, which is one of the most suitable agricultural basins for modeling surface water and groundwater in Iran. After MODFLOW model calibration, hydrodynamic coefficients of the aquifer were determined and the sensitivity of the model was checked for hydraulic conductivity and discharge rate of wells. In order to prove confidence, the model was validated. SWAT and MODFLOW models were successfully tested and the results of the combination of the two models were found to be acceptable.

“…Isto normalmente é feito com o uso de coeficientes de eficiência, que comparam dados simulados com os dados medidos em campo. Porém, medidas diretas de recarga permanecem tecnicamente inviáveis para bacias hidrográficas reais, mesmo que pequenas (Chung et al, 2010).…”

A recarga do aquífero livre é um dos processos mais importantes na hidrologia das águas subterrâneas, pois constitui reserva renovável deste manancial. Portanto, uma boa estimativa desta variável é fundamental para uma gestão adequada dos recursos hídricos, sobretudo frente à variabilidade climática inerente ao regime climático, assim como o avanço da poluição das águas superficiais e aumento da demanda por águas subterrâneas de boa qualidade. No presente trabalho, foi utilizado um modelo de balanço hídrico do solo para estimar a recarga potencial (Rp) do aquífero livre e os demais componentes do ciclo hidrológico. O modelo foi aplicado em duas bacias hidrográficas de cabeceira do Rio Grande, em Minas Gerais: a Bacia Hidrográfica do Ribeirão Lavrinha (BHRL) e a Bacia Hidrográfica do Ribeirão Marcela (BHRM). A BHRL apresentou maiores valores de Rp, com média anual de 895 mm, o que corresponde a 40% da precipitação média anual, enquanto que na BHRM estes valores foram de 393,3 mm e 25%, respectivamente. Os valores de escoamento de base confirmam essa maior recarga na BRHL, onde este componente da hidrógrafa correspondeu à 76% do total escoado, contra 40% para a BHRM. Com a modelagem empregada, foi possível captar essa diferença, porém seus resultados só foram satisfatórios para um dos anos na BHRL e para todo o período na BHRM, o que reforça a necessidade de utilizar este modelo para longos períodos de tempo.
