Spill Site Downstream Tracing
Upstream Tracing Origin
National Hydrography Dataset (NHD) Pilot Project Investigate the feasibility of integrating the NHD into RiverSpill
NHD for 3 Hydrologic Units
Reach File NHD
ERF1 (1 segment) • Mean Flow = 506.72 cfs • Mean Velocity = 1.54 fps • NHD (55 segments) • Mean Flow = 392 cfs (range: 324 - 443) • Mean Velocity =1.2 fps (range: 1.15 - 1.23) • USGS Real-Time gages • Olentangy River at Delaware, OH (upstream gage) • Mean Flow = 306 cfs • Olentangy River at Worthington, OH (downstream gage) • Mean flow = 371 cfs
