Comparing NFIE RAPID models with measured river flood hydrographs. Jeffery A Watson Department of Geosciences, University of Texas at Austin

Project objectives: Flood modelling Generate flood hydrographs from in-situ water level data. Generate hydrographs from NFIE RAPID data Identify potential sources of disagreement between modelled and measured

Study Reach: Lower Colorado River Longhorn Dam

Late October Flooding How well does NFIE RAPID predict these floods? Flood peak arrival offset How well does NFIE RAPID predict these floods? Colorado River at 183 Colorado River at Bastrop

ADCP discharge measurements Q=A*V ADCP records depth and velocity along a cross-section. Discharge calculated from these measurements. Photo from USGS: http://pubs.usgs.gov/sir/2005/5183/Figure6.gif

ADCP discharge measurements Flow Velocity Left Bank RightBank Q=8.1 +/- 0.4 m3/s Q=A*V Flow Direction Flow Direction (azimuth) Data collected by Peter Knappett’s Research team, Texas A&M, May 2015

Stage-discharge curves Provides relationship between water level and discharge. We have water level time series from pressure transducers. Allows us to calculate discharge hydrographs from water levels. Data collected by Peter Knappett’s Research team, Texas A&M, May 2015

Do flood peak arrivals match NFIE RAPID modelled predictions? Why is downstream site discharge lower?

What’s next? Identify stream segment comids Create hydrographs from NFIE RAPID data at those stream segments. Compare flood peak arrival time and discharge between NFIE and measured hydrographs.
