Water flow
GPU particles advect down Sidney's reach network, over the real NHDPlus river centerlines. Particle density and speed encode each reach's routed storm-peak flow; reaches whose receiving water can't dilute its permitted effluent at the design low flow — a deficit — thin and read oxblood. Motion is deliberately restrained.
Modeled screening flow — [inference]
The particle magnitudes are the Tier-0 Muskingum–Cunge routed hydrograph —
a screening model over cited channel geometry, not a gauged flow record — so the flow field
is [inference], never [verified]. The river
centerlines themselves are real NHDPlus geometry; the deficit shading is the cited low-flow
assimilative screen. It shows where the model routes water, not a measured discharge.
Routed per-reach attenuation
No routed reach network is on the record for this site yet. When the confluence topology and reach geometry land, the routed hydrograph and this flow view appear here.
