2012 Annual Report
Completion of post-doctoral efforts on processing, development and assessment of datasets from Reynolds Creek Experimental Watershed (RCEW) resulted in four publications, one presenting a 25-year model forcing and validation data set, one on an initial 25-year simulation of snow deposition and melt, one on interannual variability of snow deposition and melt, and one on rangeland fluxes of water and energy. Final Light Detection and Ranging (LiDAR) data processing for RCEW has been completed, and development of base DEM and vegetation structure layers has been initiated. Software engineering provided final refinements to the snow and climate software system, and modified the NRCS-developed DTK utility so that hourly precipitation surfaces could be generated. This agreement was established in support of objective 3 of the in-house project, the goal being to expand integrated snow hydrology modeling to larger scales, coupling to belowground processes, including wind effects on precipitation input, and helping to incorporate snow-related processes into ARS watershed and management simulation models (e.g., SWAT, AnnAgNPS, KINEROS, AgES, AGWA, RHEM, ISNOBAL, PIHM, etc).
