To better understand runoff generation processes in pre-Alpine catchments with low permeability gleysols, we did sprinkling and tracer experiments on two 8 m wide runoff plots. The results highlight the high velocity and celerity, the frequent occurrence of infiltration and exfiltration of overland flow, the importance of preferential flow, and the interaction between flow on the surface and through the topsoil, and help to understand why streams in this region respond very quickly to rainfall.
sapfluxnetrwill facilitate new data syntheses on the ecological factors driving water use and drought responses of trees and forests.

Where does water go when it rains?. Here we present a new way to measure how the terrestrial water cycle partitions precipitation into its two ultimate fates:
green waterthat is evaporated or transpired back to the atmosphere and
blue waterthat is discharged to stream channels. Our analysis may help in gauging the vulnerability of both water resources and terrestrial ecosystems to changes in rainfall patterns.
