“…The recharge rates, hydraulic conductivity, and storage coefficients were considered to analyze the sensitivity of groundwater flow in terms of the absolute value of mean residual groundwater level. The results indicate that the recharge rates is one of the most sensitive parameters for the groundwater level, followed by hydraulic conductivity and storage coefficients [23]. Longitudinal dispersivity has been the most sensitive parameter for groundwater salinity simulation [23].…”

“…The results indicate that the recharge rates is one of the most sensitive parameters for the groundwater level, followed by hydraulic conductivity and storage coefficients [23]. Longitudinal dispersivity has been the most sensitive parameter for groundwater salinity simulation [23]. The alternative models (models B, C, and D) were calibrated and validated to the same set of observation wells following the same procedure as the initial model A.…”

“…Intensive research into climate change indicates that impacts on the hydrological system and water resources will occur at a global scale [11][12][13][14]. The main focus of the research on climate change related to groundwater has been the impacts of changing the amount and pattern of precipitation and temperature (e.g., [15][16][17][18][19][20][21][22][23]). Changes in climatic variables can significantly alter the hydrologic cycle and groundwater recharge, which control water level and salinity distribution.…”

“…Changes in climatic variables can significantly alter the hydrologic cycle and groundwater recharge, which control water level and salinity distribution. These consequences could affect the ground surface and land capability for agriculture activities [15,20,23,24], especially in Northeast Thailand, which already has problems with groundwater and soil salinity. Several earlier studies that predicted future climate change in Thailand for different purposes [25][26][27][28][29][30][31][32] indicated an increasing trend in the average annual rainfall and temperature from 2016 to 2056.…”

Sustainable management of groundwater resources is essential for sound groundwater development, especially in sensitive salt-affected areas. In Northeast Thailand, the Central Huai Luang Basin, underlain by rock salt, is the source of groundwater and soil salinity. The future sustainable groundwater development yield was assessed under the plausible uncertainty of hydrogeological and projected climate scenarios that could impact the groundwater system. The SEAWAT and HELP3 models were used to simulate groundwater system. The four alternative scenarios of hydrogeological conceptual models were formulated to determine the impact on groundwater system and sustainable groundwater yield. In addition, impacts of projected climate conditions on each alternative model were explored. The results indicate that variable depths and thicknesses of rock salt layers have a higher impact on groundwater salinity distribution and sustainable yield estimations than model boundary conditions. Groundwater salinity, shallow water table areas, and sustainable yield projections vary substantially depending on the possible conceptual model scenarios. It is clear that the variable hydrogeological models affect groundwater sustainable yields.

“…There are many numerical models that can simulate and predict SWI [5,6] like: FEFLOW [7], SEAWAT [8,9], and SUTRA [10]. Pholkern et al [11] used SEAWAT to assess the impact of climate change on salinity distribution for both the deep and shallow groundwater systems in Huai Luang Basin (China); similarly, Colombani et al [12] evaluated the actual and future salinization in Po River Delta (Italy) using predicted data of sea level rise. De Filippis et al [13] analyzed the effect of decreasing recharge on SWI in a karstic coastal aquifer and Garzia-Ménendez et al [14] investigated the effects of the increase of the upconing process in a Mediterranean system (Spain).…”

Coastal freshwater resources are commonly under high risk of being contaminated from seawater. The main processes that affect seawater intrusion are groundwater overexploitation, land use change, and climate change effects. In this context coastal lagoons represent the more sensitive environments prone to seawater intrusion. Numerical modelling is a useful tool to understand and predict seawater intrusion. In this study, a three-dimensional SEAWAT model is employed to simulate the seawater intrusion to coastal aquifers of Variconi Oasis (Italy). The present simulation was divided into a calibration and a validation model, then the model was used to predict the salinization trend up to 2050. Results show the role of the sea in salinizing the beach front, while the retrodunal environment is characterized by transitional environments. Future seawater intrusion scenarios considering only climate data showed no significative differences in respect to the actual situation. The same happens considering also a low sea level rise prediction. On the contrary, the worst scenario (high sea level rise prediction), depicts a quite different situation, with a saline intrusion in the Variconi oasis that will severely affect the fragile transitional ecosystem. This modelling framework can be used to quantify the effects of climate changes in similar coastal environments.

To accurately obtain the spatial distribution characteristics of groundwater level in an extremely arid zone and its dynamic change patterns under the influence of human activities, based on the data of 55 groundwater observation wells in the middle and lower reaches of the Kriya River, spatial interpolation of regional groundwater level data were performed using the inverse distance weight, spline function, trend surface, and the ordinary kriging methods. The optimal interpolation method was selected by its accuracy to spatially interpolate the groundwater level data in the study area from 2019 to 2021. The results show that: (1) the ordinary kriging method has the highest interpolation accuracy (MAE = 7.1393, MRE = 0.0058, RMSE = 9.4314) and reflects the spatial and temporal variability and distribution characteristics of groundwater levels with great accuracy. (2)The relationship between surface water–groundwater recharge and discharge in different areas of the river channel in the desert section varies depending on geological structure, surface water seepage, and other elements. (3) Groundwater in the Taklamakan Desert has little effect on groundwater recharge in the Dariyabui Oasis, and changes in groundwater dynamics in the oasis are predominantly influenced by surface runoff. (4) Monthly changes in groundwater levels in the Yutian Oasis are continuous, with ‘V’ shaped fluctuations, a declining trend in the southern part, no significant change in the central part, and a slight increase in the northern part. These results contribute to the sustainable management of water resources in the Kriya River Basin, provide a basis for groundwater prediction, and offer a reference for studies of other, similar extreme desert area basins.
