“…The water curtain system can decrease seawater intrusion and reduce the influence of tidal fluctuation on the seepage field inside the island. Liu et al (2019) [6] compared different wellhead protection area (WHPA) delineation methods, addressing the delineation uncertainty due to the uncertainty from the input parameters. Comparisons were performed at two pumping sites-a single well and a wellfield consisting of eight wells in an unconfined coastal aquifer in Israel.…”

Groundwater is an essential and vital water resource for drinking water production, agricultural irrigation, and industrial processes. The better understanding of physical and chemical processes in aquifers enables more reliable decisions and reduces the investments concerning water management. This Special Issue on “Water Flow, Solute and Heat Transfer in Groundwater” of Water focuses on the recent advances in groundwater dynamics. In this editorial, we introduce 12 high-quality papers that cover a wide range of issues on different aspects related to groundwater: protection from contamination, recharge, heat transfer, hydraulic parameters estimation, well hydraulics, microbial community, colloid transport, and mathematical models. By presenting this integrative volume, we aim to transfer knowledge to hydrologists, hydraulic engineers, and water resources planners who are engaged in the sustainable development of groundwater resources.

“…By modeling the particle motion, their forward and backward motion could be simulated to determine the origin and destination of contamination [6]. Moreover, the wellhead protection area could also be determined over time, using the particles' modeling [21,22]. In this study, to model the contaminant transport path, MODPATH numerical code-which is a threedimensional, particle-tracking, post-processing program developed by Pollock [32]-was used to determine the particle motion's direction and time.…”

Recognitions and predictions of the contamination origin are essential steps in the protective measures to avoid wellwater contamination and the first step in managing groundwater resources. In this regard, finite-difference model software (GMS 10.0.6) was used to model the transport path, the origin of contaminants and to determine the wellhead protection area in Iranshahr aquifer. Since contamination transport models require a calibrated groundwater flow model, we first prepared this model. Accordingly, after collecting all geological, meteorological, hydrological and hydrogeological data (based on the maps, geophysical tests and exploratory borehole drilling, rainfall statistics and groundwater level in exploitation wells), a database was constructed in ArcGis10.1 software and a conceptual model was developed by transporting this information to GMS software. Based on the developed model, the aquifer's groundwater level was simulated, calibrated and validated using MODFLOW2000 code in GMS software. The particle transport model in the aquifer was provided to examine and model the transport path and the origin of contaminants through MODPATH module. In the end, the aquifer wells' protection area against contaminants was illustrated. According to the results, contaminant transport path in the wells of central plains is directed from the river to the wells, in forward particle-tracking model; the maximum time taken by particles is 508,952.5 days, the minimum time is 144 days, and the average radius of 50-day wellhead protection area based on the protection against contaminations such as pathogenic bacteria in Iranshahr aquifer was determined to be about 100 m.
