英文摘要	Identifying the scale-dependent control of various surface factors on a groundwater system is a challenge due to the potential interdependence between these factors. Here, this challenge was addressed using partial wavelet coherency (PWC), which can detect localized and scale-specific bivariate relationships between predictor and response variables after removing the impact of other variables. The analysis was done for groundwater systems in a humid area (Tuscaloosa, Alabama) and an arid area (Lake Havasu City, Arizona). The results indicate that the total precipitation and precipitation duration show the advantage in controlling the groundwater flow in humid and arid areas, respectively. Precipitation has more significant impacts on the coherence between surface water and groundwater in an arid area, which decreases by 3% on small time scales (< 120 days) and increases by 6% on large scales (> 120 days). However, surface water shows more important effects on the coherence between precipitation and groundwater on large scales in a humid area, which decreases by 47%. Overall, the analysis highlights that the impacts of precipitation (or surface water) on the coherence between surface water (or precipitation) and groundwater level are changing with the time scale and climatic belt. The temporal scale dependency is primarily led by the seasonality of the influence factors, while the spatial dependency is mainly due to various evapotranspiration rates and drought/flood episodes. These findings provide useful insights into untangling the localized and scale-specific bivariate relationships in a groundwater system, which is an important topic in water-resource prediction.
