Many Objective Decision Support For Water And Environmental Problems Under Deep Uncertainty

Aug. 13, 2018

Kasprzyk , Joseph 1 1 University of Colorado 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...

River Response To Dam Removal: A Synthesis Perspective

Aug. 13, 2018

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...

Groundwater’s Role In Mitigating Mountain Water Resource Impacts From A Changing Climate: Geochemical Insights From A Subalpine, Headwater Catchment, Colorado, USA

Aug. 6, 2018

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...

A Sensor Driven Transformation In The Hydrologic Sciences: How New Tools Are Enabling New Insights In Catchment And River Processes

Aug. 6, 2018

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...
