Mutually intelligible variations in hydrologic function across the Critical Zone Observatory network: A step towards understanding the hydrologic coevolution of the critical zone


The physical and biological architecture of the Earth’s Critical Zone controls hydrologic partitioning, storage, and chemical evolution of precipitated water. The Critical Zone Observatory (CZO) network is a consortium of field sites that provides an ideal platform to research linkages between catchment structure and hydrologic function across a gradient of geologic and climatic settings. A legacy of hypothesis-motivated research at each site has created an assemblage of data useful for characterizing the architecture and hydrologic function of the critical zone. We will present a synthesis of this data that aims to elucidate and explain (in the sense of making mutually intelligible) variations in hydrologic function across the CZO network. This research analyzes precipitation, streamflow, and meteorological data to extract top-down quantitative signatures of the storage and partitioning of water at catchment scales, which may be used as quantitative benchmarks to assess perceptual models of hydrologic function at each CZO site.
