Short summary
Rivers with alternating patterns of shallow and deep flows are commonly observed where a river widens and then narrows, respectively. But what if width changes over time? We use a lab experiment to address this question and find it is possible to decrease and then increase river width at a specific location and observe that flows deepen and then shallow consistent with expectations. Our observations can inform river restoration and climate adaptation programs that emphasize river corridors.
