Kasprzyk , Joseph 1 1 University of ÃÛÌÇÖ±²¥ Boulder In environmental planning problems, decision makers' goals often fundamentally conflict. Faced with limited budgets, planners realize that increasing their systems' performance could cause increased costs, negative impacts to the environment, or conflicts among stakeholders. Multi-objective decision support techniques are increasingly used...

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...

Dailey , Kelsey R 1 ; Hughes , Holly 2 ; Williams , Mark 3 1 Environmental Studies, INSTAAR 2 INSTAAR 3 Geography, INSTAAR Geochemical surface and groundwater data were used to examine groundwater recharge dynamics and hydrologic connectivity in the dominantly subalpine Como Creek headwater catchment within the Boulder...

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...
