David Litwin is a second year PhD student in environmental engineering studying the coevolution of landscapes and groundwater systems. He is a recipient of the Horton research award from AGU, and a first year member of H3S. When not writing code or in class, he likes to hike, play the double bass, and read fiction.
Rivers end at the sea, or so we are taught. However, the study of fluvial hydrology commonly ends where tidal influence begins. Here, fluvial and marine forces overlap in long transitional regions (often 100s of kilometers) where coastal cities and ports face a double threat from river flooding and storm surge.
When rain falls on a watershed, a diverse array of processes are set in motion, moving water from the canopy, into and across the ground surface, through pores in soil and rock, and eventually into streams as runoff.
