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...
