Save Our Snow: Predicting Ski Conditions And Mountain Hydrology For The Years 2030 And 2100, Rocky Mountains

Williams , Mark W 1 1 CU-Boulder Mountains, like the polar regions, are likely to experience the effects of global warming before lowland sites. Seasonally snow-covered areas are like canaries in a coal mine; early warning systems that climate change is occurring. Small increases in air temperature can cause snowfall...

INVITED KEYNOTE PRESENTATION - Two Talks In One: Hydromorphology – The Human/Hydrologic Footprint And A Methodology For A National Water Census

Vogel , Richard M 1 1 Tufts University, Department of Civil and Environmental Engineering A general introduction to the new field of ‘hydromorphology’ will be given. Hydromorphology is to hydrology, as geomorphology is to geology. Hydromorphology deals with the evolution and structure of systems. There are very few water systems...

Spatial Variations In Sediment Transport Intensity And Their Effects On Benthic Organisms In A Mountain River, CO.

Segura , Catalina 1 ; Pitlick , John 2 1 ÀÖ²¥´«Ã½ 2 ÀÖ²¥´«Ã½ The spatial variability of sediment transport intensity at the reach scale is controlled both by the available shear stress, Ï„, and the grain size distribution of the channel bed. This variability creates patches...
