Montandon , Laure 1 ; Small , Eric E. 2 1 ²ÊÃñ±¦µä 2 ²ÊÃñ±¦µä The green vegetation fraction (Fg) is an important climate and hydrologic model parameter. Common methods to calculate Fg, like the Gutman and Ignatov (GI) approach and its derived quadratic version, are simple mixing models...

Molotch , Noah 1 1 University of Colorado, Cooperative Institute for Research in Environmental Sciences CIRES A spatially distributed snowmelt model was used to simulate pixel-specific daily snowmelt and snow water equivalent (SWE) over the Rio Grande headwaters (3,419 km2). Melt flux estimates were coupled with three different time-series of...

Mallikamas , Wasin 1 ; Rajaram , Harihar 2 1 University of Colorado 2 University of Colorado We present theoretical and computational analyses of the anisotropy of the aperture correlation structure and effective transmissivity in fractures generated by sliding between identical self-affine surfaces. The anisotropy resulting from shear has been...

Logan , Brandy L 1 ; Pitlick , John 2 1 University of Colorado 2 Univeristy of Colorado Sustained drought in the Upper Colorado River Basin has severely limited peak flows, allowing native and non-native plant species to colonize low-lying bar surfaces within the last five years. This vegetation has...
