“…A pesar de contar con una modelación más fina, los alcances de este trabajo no se han verificado con aforos, pues hasta la fecha existe un vacío de información al respecto; de igual manera, la información sobre calidad del agua y distribución temporal es deficiente. SWB ha probado su utilidad en la simulación del ciclo hidrológico con resultados importantes en Estados Unidos de Norteamérica (Tillman et al, 2016;Zhang, Felzer, & Troy, 2016), con variaciones de ±33 mm al año en la estimación de la recarga; se ha encontrado alta confianza en los resultados de la modelación, a escala regional, cuando se utilizan datos a resolución mensual y anual (Han et al, 2018). Los estudios sobre la aplicación del modelo SWB dan cuenta de su utilidad como herramienta para apoyar los procesos de gestión del agua en cuencas.…”

“…Since groundwater basin divides generally follow surface topography in wet years and subsurface topography in dry years, we delineated the groundwater basin only for the dry years between 2011 and 2017. Data retrieved from the Wisconsin State Climatology Office website (http://www.aos.wisc.edu/~sco/ clim-history/state/graphics/WI-precip-annual.gif) reveal that only 2012 was a dry year, and the drought of 2012 caused low groundwater levels from late 2011 until spring of 2013 (Han et al 2018). Therefore, the static water level of wells drilled during this time period were used to create the groundwater DEM used to delineate the groundwater basin for 2012.…”

Understanding the factors that affect groundwater-surface water interactions will lead to policy decisions that will both protect stream habitats and provide for the needs of the agriculture industry.ABSTRACT: When it comes to water resources management, it is critical to understand the factors that affect baseflow processes. Declines in baseflow due to increased use of the groundwater from unconfined aquifers is well documented, but that is not the case for confined aquifers. Furthermore, since the groundwater basin size and shape can be different than the surface water basin, the use of the surface basin to determine well withdrawal rates can affect baseflow and be problematic. This study used the variables determined to be related to baseflow variability (precipitation, temperature, drainage class, available storage, land use, and slope) and the withdrawal rates of wells located within the study basins to create regression models for the state of Wisconsin, United States. We find that: (1) precipitation and temperature variable are significant in explaining the temporal variability of baseflow, whereas land cover variables are important when the temporal variability is not considered; (2) evaporation and soil drainage are important in basins over unconfined aquifers, whereas precipitation the most significant over confined aquifers; (3) whether to use surface water or groundwater divides to delineate basins matters in particular conditions, and (4) groundwater withdrawal rates do not significantly affect baseflow when using statistical analysis. Therefore, analyzing baseflow should be supplemented by a process-based model for the effects of groundwater withdrawals.

“…Groundwater recharge can be evaluated by using water budget with seepage meters [42,43], tracers [44,45], modelling [46,47], and groundwater level change [48]. To analyze the water budget and estimate the groundwater recharge in the MRB area, we used the soil-water balance (SWB) model, which has been applied in various studies to understand the impact of future climate change and anthropogenic effects on groundwater resources [49][50][51]. The SWB model integrates GIS-gridded datasets (land-use classification, soil properties, flow direction, and available soil-water capacity) with observed climate data (precipitation, air temperature, and evaporation).…”

Natural and Human-Induced Drivers of Groundwater Sustainability: A Case Study of the Mangyeong River Basin in Korea

The sustainability of rural areas depends on the availability of water resources. The Mangyeong River Basin (MRB) in Korea faces a water supply shortage for agriculture and industry. Based on 11-year (2005–2015) precipitation and groundwater monitoring data, groundwater sustainability was evaluated in terms of natural and man-made factors and their spatio-temporal variations. A precipitation time-series revealed a declining trend, but there were different seasonal trends between wet and dry periods, with declining and rising trends, respectively. Groundwater hydrographs from five national groundwater monitoring wells showed temporal variations. Groundwater wells located in downstream areas showed both recharge from upgradient areas and local man-made impacts (e.g. from pumping), resulting in an ambiguous relationship between precipitation and water levels. However, other monitoring wells in the upstream areas displayed water level responses to precipitation events, with a declining trend. Using the standardized precipitation index at a time scale of 12 months (SPI-12) and the standardized groundwater level anomaly, meteorological and groundwater drought conditions were compared to infer the relationship between precipitation deficit and groundwater shortage in the aquifer. The SPI results indicated severely dry to extremely dry conditions during 2008–2009 and 2015. However, the standardized groundwater level anomaly showed various drought conditions for groundwater, which were dependent on the site-specific hydrogeological characteristics. Finally, groundwater sustainability was assessed using water budget modelling and water quality data. Presently, if groundwater is used above 39.2% of the recharge value in the MRB, groundwater drought conditions occur throughout the basin. Considering water quality issues, with nitrate being elevated above the natural background, this critical abstraction value becomes 28.4%. Consequently, in the MRB, sustainable groundwater management should embrace both natural and human-induced factors to regulate over-exploitation and prevent contamination.
