The daily- and monthly-baseflow estimates at reference stream gages provide an initial understanding of the temporal and spatial variability of natural baseflow across the basin. The monthly-baseflow estimates will be used as calibration data in a random forest model that will be coupled with 200 potential predictor variables (static watershed characteristics and temporally-variable climate data) to generate monthly estimates of natural baseflow for all stream reaches in the Delaware River Basin defined by the National Hydrography Dataset (NHD) Version 2.0 for the period 1950-2015. Quantitative estimates of the amount and timing of baseflow, a surrogate for the volume of groundwater discharged to streams, can be applied to address questions of the vulnerability and response of aquatic ecosystems to natural and human-induced changes in environmental conditions.
