When impervious cover doesn't predict urban runoff: Lessons from distributed overland flow modeling

These are the datasets used in the paper by Kirker, A N, and L Toran. 2023. We used the distributed hydrologic model GSSHA to simulate overland runoff from impervious and semi-pervious (low vegetation) land covers in a 0.3 km2 urban catchment. To track the arrival of water to a stormwater basin inlet from distinct parts of the catchment, we applied a conservative solute tracer to portions of the gridded model area. These data show the variability in discharge amount and solute arrival for modeled scenarios with different slopes, land uses, and precipitation amounts. A full model run has also been included in the .zip file so that users of Aquavevo's WMS may replicate these results.
