“…Hence, stable base flow analysis was used to examine and estimate the groundwater recharge. Lee et al [7] pointed out that the calculated base flow is likely to be overestimated when the base flow estimation method is used to assess stream flow data. This will in turn affect the calculations of the groundwater recharge.…”

“…This method utilized the stream flow data to separate the base flow, which is regarded as the groundwater recharge. However, for rainy and humid regions and steep mountainous areas, if the estimation of groundwater recharge is based solely on base flow separation, it will often lead to overestimation of the base flow during the wet season [7,28]. Therefore, the calculation of a steady base flow separation is required.…”

“…When analyzing the hydrogeological model and groundwater system of a region, the study on recharging groundwater through precipitation is a very important but complex issue. Meteorological factors (e.g., intensity and delay of precipitation, temperature, humidity, and wind speed), thickness of the soil layer, prevailing groundwater level, topographical conditions on the surface, vegetation cover, and land uses, all have direct relationships with the system and must be considered [4][5][6][7][8][9][10]. It is very easy to measure precipitation and run-off amounts when analyzing water balance, but it is very difficult to quantify the recharging process.…”

“…However, it is generally more difficult to implement the second method because of high costs and the need for long-term monitoring on site. The existing methods for estimating groundwater recharge at the regional level using the water balance model are further divided into two types: (i) precipitation, infiltration, runoff, evapotranspiration, and groundwater recharge are treated as components of an interrelated system, with the soil moisture status being that of an ever-changing soil water balance model [7,20,21]; and (ii) the hydrograph of a stream flow is used to estimate its base flow, with the latter being treated as the groundwater recharge (based on the assumption that the heterogeneous hydrogeological conditions within the catchment area are ignored) [22][23][24][25][26].…”

In this study, the base flow estimation method was used to assess long-term changes of groundwater recharge in Northern Taiwan. The Mann-Kendall test was used to examine the characteristics of the trends. This was followed by trend slope calculation and change-point analysis. The annual groundwater recharge was found to exhibit a significant upward trend for the Fushan and Hengxi stations (Tamsui river basin). On the other hand, the Ximen Bridge station (Lanyang river basin) recorded a significant downward trend. Calculations showed that the rate of change for the Fengshan and Touqian river basins was small (less than 10%). However, that for the following stations was greater than 30%: Fushan, Hengxi, Ximen Bridge, and Niudou (also in the Lanyang river basin). The results of the change-point analysis further indicated a significant change-point for the annual recharge at Fushan, Hengxi, and Ximen Bridge stations in 1999, 1983, and 2001. The findings can be used for regional hydrological studies and as reference for water resource planning.

“…Moreover, in this approach, the temporal lags of groundwater level dynamics to precipitation at different regions can be identified [36,[42][43][44][45][46]. Therefore, the spatiotemporal patterns of characterized results can help to understand hydrological processes, validate the simulated results of a hydrological model, and promote sustainable use of groundwater resources [10,[42][43][44]. In addition, the results can also help assess aquifer vulnerability to climate change [45].…”

Identifying the spatiotemporal change of the groundwater table to precipitation at the river basin scale can be important for regional water resource management. In this study, we proposed a method that combines singular value decomposition and cross-wavelet approaches to analyze the relationship between groundwater level dynamics and precipitation. The method was applied to the Naoli River Basin, Northeast China. Moreover, the method of continuous wavelet using fast Fourier transform was also used to reveal clearly the relationship between groundwater level and heavy precipitation. The results showed that the major mode of relationship between groundwater and precipitation was divided into four patterns in the study area. In general, the lag time is 27.4 (standard deviation: ±8.1) days in pattern 1, 107.5 (standard deviation: ±13.2) days in pattern 2, 139.9 (standard deviation: ±11.2) days in pattern 3, and 173.4 (standard deviation: ±20.3) days in pattern 4, respectively. In addition, the response of groundwater level dynamics is very sensitive to heavy precipitation in all patterns. Therefore, enhancing the utilization of heavy rainfall and flood resources is an effective way to increase groundwater recharge in this basin.
