The Impact Of Soil Reflectance On The Quantification Of The Green Vegetation Fraction

Montandon , Laure 1 ; Small , Eric E. 2 1 CU Boulder 2 CU 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...

INVITED TALK: Reconstructing Snow Water Equivalent In The Rio Grande Headwaters Using Remotely Sensed Snow Cover Data And A Spatially Distributed Snowmelt Model

Molotch , Noah 1 1 ÀÖ²¥´«Ã½, 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...

Theoretical And Computational Studies Of Hydraulic Anisotropy In Shear Fractures With Self-Affine Surfaces

Mallikamas , Wasin 1 ; Rajaram , Harihar 2 1 ÀÖ²¥´«Ã½ 2 ÀÖ²¥´«Ã½ 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...

Interactions Between Vegetation Expansion And Flow Dynamics On The Colorado River, CO, USA

Logan , Brandy L 1 ; Pitlick , John 2 1 ÀÖ²¥´«Ã½ 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...

Different Effects Of The Heat Sources Of Surrounding Oceans On The East Asian Summer Monsoons (EASM)

Lee , Eungul 1 ; Chase , Thomas N. 2 ; Rajagopalan , Balaji 3 1 CIRES and Geography, Univ. of Colorado at Boulder 2 CIRES and Geography, Univ. of Colorado at Boulder 3 CIRES and CEA Engineering, Univ. of Colorado at Boulder Northern East Asian summer monsoon precipitation (NEASMP)...

The Everglades Ridge And Slough Landscape: A Linear Combination Between Boreal Bogs And Anabranching Rivers?

Larsen , Laurel G. 1 ; Harvey , Judson W. 2 ; Crimaldi , John P. 3 1 ÀÖ²¥´«Ã½ 2 U.S. Geological Survey, Reston, VA 3 ÀÖ²¥´«Ã½ The ridge and slough landscape of the Florida Everglades is a patterned peatland, with elevated sawgrass ridges interspersed among...

Simple Hydroecological Models: Is Root Zone Average Soil Moisture An Adequate Driver In The Functions For Evapotranspiration And Assimilation?

Kurc , Shirley A 1 ; Small , Eric E 2 1 ÀÖ²¥´«Ã½, Geological Sciences 2 ÀÖ²¥´«Ã½, Geological Sciences In water-limited semiarid and arid areas, the ecosystem scale exchanges of water and carbon between the land surface and the atmosphere are complex. Both the water and...
