Neupauer , Roseanna M 1 1 Univ. of Colorado Wavelet analysis is a relatively new tool for data analysis and signal processing. Similar to Fourier analysis, wavelet analysis identifies dominant periods or scales in one-dimensional and multi-dimensional data sets. The key difference between Fourier analysis and wavelet analysis is in...

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...
