H32D:
Suggesting New Hypotheses and Informing Models: What Are We Learning from Long-Term Catchment Monitoring Data and Catchment Experiments? I


Session ID#: 10617

Session Description:
Data collection at long-term catchment studies across the globe now extends for periods of 20 – 50 or more years. These data along with associated experiments have informed our understanding of the interaction and evolution of soils, surface waters, and vegetation at these sites and have provided new insights to ecosystem processes and responses to environmental change. In this session, we seek contributions from long-term and experimental catchment studies, including analyses of temporal change, tests of existing hypotheses, and the emergence of new hypotheses that are advancing our understanding of catchment systems and informing models that can help predict future conditions.
