Observing and Simulating Earth’s Surface Waters

– Cédric David – Scientist, NASA’s Jet Propulsion Laboratory/California Institute of Technology

Résumé : The freshwater in Earth’s rivers, lakes and reservoirs might be small (in volume), but it is also mighty (in flow). As such, surface waters are the most accessible and the most renewable sources of freshwater, and can be argued to be the key to water sustainability. Yet, our ability to monitor and simulate the stores and fluxes of water on Earth’s continents is still relatively limited. In this presentation, we will time-travel from early global river models, to the birth of continental-scale hydrographic datasets, to the digital simulation of river flow aided by high performance computers, and look forward towards merging computer models with global observations of rivers from Earth orbiting satellites; with implications for the upcoming Surface Water and Ocean Topography (SWOT) mission and the planned Small Altimetry Satellites for Hydrology (SMASH).
