The National Water Model: The first comprehensive framework for predicting streamflow
Impact to University Research of National Water Model
University Engagement in National Water Model
• Framework for Collabora.on – Hydrofabric – Interdisciplinary research
• Research to Opera.ons – Regionally specific hydrologic mechanisms – Test bed for different process representa.ons
• Plumbing of con.nent to link sky to sea – Mountains-‐to-‐sea at high resolu.on – Transport layer
Summer Institute at National Water Center
University Engagement in National Water Model
• Na.onal Water Model and Training – Summer Ins.tutes at Na.onal Water Center in 2015 and 2016
– ~70 graduate students engaged 7-‐week training • Research Contribu.ons
– Exploratory test beds for new ideas – Proof of concept

Future Research: Refining Physics of National Water Model
• Groundwater Processes – Including aquifers, as well as soils – Cri.cal for understanding drought
• Water rou.ng – Move beyond wave of water to parcels of water – Cri.cal for water chemistry
• New Data for Model Valida.on – Incorporate new NASA satellite data (GRACE, SMAP) – Test at research catchment scale (NSF, USFS, USDA, DoE, USGS)
