Neupauer , Roseanna M 1 1 Univ. of ÃÛÌÇÖ±²¥ 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...

Montandon , Laure 1 ; Small , Eric E. 2 1 ÃÛÌÇÖ±²¥ Boulder 2 ÃÛÌÇÖ±²¥ Boulder 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 ÃÛÌÇÖ±²¥, Cooperative Institute for Research in Environmental Sciences ÃÛÌÇÖ±²¥ 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 ÃÛÌÇÖ±²¥ 2 University of ÃÛÌÇÖ±²¥ 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 ÃÛÌÇÖ±²¥ 2 Univeristy of ÃÛÌÇÖ±²¥ Sustained drought in the Upper ÃÛÌÇÖ±²¥ 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...
