“…In addition to these publications, many regional-scale models were developed with MODFLOW in the United States and China for integrated water management purposes (Rossman and Zlotnik, 2013;Zhou and Li, 2011). Except for Monteil (2011) and Pryet et al (2014), none of these explicitly focus on distributed stream-aquifer exchanged water flux.…”

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.

“…Groundwater modelling could be a suitable tool to represent the natural groundwater flow in the environment and to predict the fate and movement of solutes and potential contaminants under natural or hypothetical scenarios [6]. Such models can be used to predict the effects of groundwater abstraction and irrigation developments with regard to the aquifer and to simulate various water management scenarios [7].…”

Abstract:The use of inverse methods allow efficient model calibration. This study employs PEST to calibrate a large catchment scale transient flow model. Results are demonstrated by comparing manually calibrated approaches with the automated approach. An advanced Tikhonov regularization algorithm was employed for carrying out the automated pilot point (PP) method. The results indicate that automated PP is more flexible and robust as compared to other approaches. Different statistical indicators show that this method yields reliable calibration as values of coefficient of determination (R 2 ) range from 0.98 to 0.99, Nash Sutcliffe efficiency (ME) range from 0.964 to 0.976, and root mean square errors (RMSE) range from 1.68 m to 1.23 m, for manual and automated approaches, respectively. Validation results of automated PP show ME as 0.969 and RMSE as 1.31 m. The results of output sensitivity suggest that hydraulic conductivity is a more influential parameter. Considering the limitations of the current study, it is recommended to perform global sensitivity and linear uncertainty analysis for the better estimation of the modelling results.

Due to overcapacity, the current airport of Yogyakarta is going to be replaced with a new one, which is located in Wates coastal area, Kulon Progo District, Yogyakarta Special Province, Indonesia. One of the consequences of the development of the new airport is groundwater abstraction due to the airport's needs and related supporting activities. An excessive withdrawal of groundwater in the new airport will potentially change the system and the pattern of groundwater flow. Therefore, groundwater modeling should be done to predict the impact of groundwater abstraction in this area. MODFLOW code is used to simulate the groundwater flow and the impact of groundwater pumping in the Wates coastal aquifer. The model is calibrated using water level data from 40 wells in the research area. The results show that the calculated values are fit to the measured data, which indicates that the model is reliable. The effects of groundwater pumping on water table and seawater intrusion are investigated using a calibrated model. The results show that the pumping scenario from the airport area causes the groundwater level to drop 0.75 m and seawater intrusion inland to increase around 100 m.
