Topographic depressions and hydrologic connectivity in the United States

Kerry Callaghan, University of Illinois Chicago Chicago Illinois, United States. kerryc@uic.edu

Hydrologic connectivity can change as climate changes, seasonally, or even after a single rain event. Here, I assess the depression structure of the topography of the United States and determine its capacity to hold surface water in lakes. I provide results from a simulation indicating the pre-industrial water level in these depressions and the resulting degree of hydrologic connectivity. I then share results from a series of experimental simulations to modify water levels and the resulting hydrologic connectivity across the country.
