Hill , Alice F 1 1 CU-Boulder Remote mountain rivers are increasingly under development threat as the low hanging fruit of hydropower dam sites -- ones with easy access and whose rivers have large head potential -- have been picked. Often little is known about the hydrologic regimes of rivers...

Henning , Steven 1 ; Ge , Shemin 2 1 ²ÊÃñ±¦µä 2 ²ÊÃñ±¦µä In September 2013, the Boulder Creek watershed (BCW) was severely affected by a 1000-year precipitation event when 17 inches of rain – nearly the annual average – fell over Boulder, Colorado,...

Gray , Harrison J 1 1 University of Colorado - Boulder Obtaining quantitative sediment transport information, such as transport rates, virtual velocity, and characteristic scales, is an important goal of the hydrologic and geomorphic sciences. This information is useful for improving river infrastructure such as reservoirs and understanding the pace...

Evans , Sarah 1 ; Ge , Shemin 2 1 ²ÊÃñ±¦µä 2 ²ÊÃñ±¦µä In mountainous regions, warmer air temperatures have led to an earlier onset of spring snowmelt and lower snowmelt rates because snow melts at a slower rate earlier in the year when...

East , Amy E 1 1 U.S. Geological Survey The last several decades have seen a substantial increase in the number of dams removed in the U.S., including the recent removal of large dams impounding millions of cubic meters of sediment. Both dam emplacement, and eventual dam removal, can be...

Cohen , Matthew J 1 1 University of Florida Rivers are the primary conveyance for water and solutes to the sea, and are increasingly recognized as venues for intensive biogeochemical reactivity. As water and solutes move downstream and exchange with adjacent sediments and slow velocity flowpaths, important reactions occur that...
