ABSTRACT:
This resource accompanies "Shifting runoff sources shape wetted channel length-discharge hysteresis" by David N. Dralle, Dana A. Lapides, and W. Jesse Hahm. It contains the Python code, synthetic model outputs, figure, and interactive HTML supplement used to examine how changing runoff-source patterns alter wetted channel extent at a given outlet discharge.
The model combines simultaneous, upstream-moving, or downstream-moving recharge with spatial differences in hillslope drainage. Six scenarios illustrate how these processes reinforce or oppose one another, changing the direction and width of L-Q hysteresis under instantaneous routing and fixed wetting thresholds.
The standalone HTML runs offline and supports parameter exploration, CSV downloads, and video export. All inputs are synthetic. The paper figure uses 30 discrete sources; the interactive supplement defaults to 600 finite-area cells. The README provides run instructions, file descriptions, and units.
