RiverSpill Capabilities

Downstream Tracing Operational for the Continental US Instantaneous and Continuous Release Chemical and Biological Agents Flow: Automated, User Selected, User Defined Inclusion of Temperature in Biological Calculations Enhanced User Control and Reporting Additional Databases

Water Treatment Plants, Sewage Treatment Plants, Dams, RMP Locations, Railroads, HUCs

Display of Hydrologic Units Find River Query

RiverSpill Capabilities(continued)

Upstream Tracing Operational for the Continental US Trace by Time or Distance Time Tracing Based on Mean or User Defined Flow Enhanced Reporting

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
