“…On average, 70% streamflow was contributed by baseflow in the studied watersheds [24]. As shown in Figure 3, the correlation coefficient between Q/P and BFI in the remaining 15 watersheds (Trap Rock River and Macatawa River watersheds were excluded) approaches to 0.5.…”

“…Mean annual ETa/P ratio and runoff coefficient (Q/P) in the study watersheds varied from 0.34 to 0.71 and from 0.29 to 0.66, respectively (Table 1). Low ETa/P ratio under similar P was likely attributed to snowiness as Q in the Trap Rock River watershed mainly originated from snow fall and spring snowmelt [24]. Berghuijs et al [39] also reported that snowy catchments have a high runoff ratio in context of the Budyko hypothesis.…”

“…The default recess constant and BFImax values of 0.98 and 0.8 were employed, respectively. The specific principle of the recursive partitioning algorithm was shown in detail in the study by Zhang et al [24]. Then, baseflow index (BFI) was calculated by dividing mean annual baseflow by mean annual streamflow to quantify groundwater contributions to streamflow in the 17 study watersheds.…”

“…On average, baseflow accounted for 70% of the total streamflow in those 17 watersheds [24]. The specific objective of this study were to (1) test the applicability of Fu's Equation in estimating mean annual water balances for 17 watersheds in Michigan; and (2) investigate the relationship between baseflow and climatic sensitivity in Michigan watersheds using Fu's Equation.…”

Evaluation of water balance at the watershed scale is a fundamental step for estimating streamflow in watersheds. Mean annual water balance of 17 watersheds across Michigan were evaluated by comparing observed streamflow with simulated streamflow estimated using Fu's Equation, which is based on the Budyko Hypothesis. The Budyko Hypothesis describes mean annual water balance as a function of available water and energy. Impact of long-term climatic controls (e.g., precipitation, potential evapotranspiration (ETP)) on mean annual water balance was also investigated with Fu's Equation. Results indicated that observed streamflow ranged from 237 to 529 mm per year, with an average of 363 mm per year in the study watersheds during 1967-2011. On average, 40% of long-term precipitation in the study watersheds was converted into surface runoff. The performance of Fu's Equation in estimating mean annual streamflow resulted in Root Mean Square Error (RMSE) value of 64.1 mm/year. Mean annual streamflow was sensitive to changes in mean annual precipitation, and less sensitive to changes in mean annual ETp in the watersheds. With the increase of baseflow index (BFI), mean annual streamflow was less sensitive to climate change. Overall, different contributions of baseflow to OPEN ACCESSWater 2015, 7 3566 streamflow modified the impact of climate controls on mean annual water balance in the baseflow-dominated watersheds.

We present a regression model for estimating mean August baseflow per square kilometer of drainage area to help resource managers assess relative amounts of baseflow in Maine streams with Atlantic Salmon habitat. The model was derived from mean August baseflows computed at 31 USGS streamflow gages in Maine. We use an ordinary least squares regression model to estimate mean August baseflow per unit drainage area from two explanatory variables: percentage of the basin underlain by sand and gravel aquifers and mean July precipitation in the basin. This model provides the ability to estimate mean August baseflow in cubic meters per second per square kilometer of basin area on user-selected, ungaged sites throughout Maine south of 46 21 0 55 00 N latitude. The model has an adjusted R 2 of 0.78 and a mean 95% prediction interval of plus or minus 0.002 cubic meters per second per square kilometer. A map of the Narraguagus watershed in eastern coastal Maine shows reaches color coded by relative amounts of baseflow predicted by the model as an example of how this method could be applied throughout Maine. The map can be used to identify reaches with relatively higher amounts of baseflow during summer low flows for habitat conservation and restoration work. These areas have the potential to be high-quality habitat for Atlantic salmon and other cold-water fish because baseflows are known to moderate stream temperatures in summer low-flow periods.
