The fate of bars in braided rivers
UNRAVELING SOURCE-TO-SINK DYNAMICS FROM SEDIMENTARY RECORDS II ORAL
earth and planetary surface processes | 15 december 2023
Safiya Alpheus, Elizabeth A. Hajek
Rivers adjust their planform and migration patterns as they equilibrate to local and basin-scale perturbations in discharge and sediment supply. These...
