The groundwater storage is one critical component in the terrestrial water budget. With the assist of the remote sensing images, the story of the water storage, from surface water, soil moisture or groundwater, will be unfolded first.

Baseflow recession analysis reveals the complicated story of the groundwater by deriving the characteristic drainage timescale. However, the streamflow data availability makes this analysis in the real-world application not easy to accomplish. An increasing trend is observed from recent research to interpret the baseflow recession from a geomorphic perspective. For the 17 watersheds in central Minnesota, a multivariate analysis for the characteristic drainage timescale on a watershed scale is conducted and yields some interesting results.
