Dust Enhanced Runoff Classification


Dust Enhanced Runoff Classification


CODOS has now observed eleven seasons of dust-enhanced snowmelt runoff behavior throughout the Colorado mountains (WY 2006-2018).  Hydrographs at headwater stream gauges have been evaluated and classified within the framework of this dust enhanced snowmelt runoff space utilizing a 3 x 3 x 3 cell matrix corresponding to general characterizations of SWE, dust intensity, and spring weather, as shown in this figure.

 

A conceptual dust enhanced snowmelt runoff model integrating the interactions of March 1 SWE, dust intensity, and spring precipitation.

 

Water Years 2006-2018 have been analyzed and classified for the following stream gauges associated with the Park Cone CODOS site:

Taylor River at Taylor Park (pdf)East River at Almont (pdf)Lake Fork at Gateview (pdf)

For a detailed discussion of this approach, see the state-wide Dust Enhanced Runoff Classification section

SWE Plots


for Park Cone CODOS site

 

For each Snotel site below, the first nine plots show a single Water Year's SWE relative to the site's historical record (1971 - current). The last two plots compare SWE and Dust on Snow events for two consecutive years. The shaded bands represent non-exceedence percentiles in the following order (from the bottom up):

  • Minimum - 10th percentile (dark gray)

  • 10th - 30th percentiles (medium gray)

  • 30th - 70th percentiles (light gray) with 50% trace in the middle

  • 70th - 90th percentiles (medium gray)

  • 90th - maximum (dark gray)

Snowmelt Rates


for Park Cone CODOS Site

Analysis of Park Cone Snotel data for Water Years 2006-2017 snowmelt seasons showing date and quantity of peak SWE, days from peak SWE to “snow all gone” (SAG), total additional precipitation after the date of peak SWE, an “adjusted” mean daily rate of snowmelt adding the additional precipitation to the peak SWE total, the maximum five-day moving average of daily melt, and the mean air temperature over the entire snowmelt period, from peak SWE to SAG. POR refers to the snotel's entire period of record.


Analyses of Schofield Pass Snotel data for Water Years 2006-2017 snowmelt seasons showing date and quantity of peak SWE, days from peak SWE to "snow all gone" (SAG), total additional precipitation after the date of peak SWE, an "adjusted" mean daily rate of snowmelt adding the additional precipitation to the peak SWE total, the maximum five-day moving average of daily melt, and the mean air temperature over the entire snowmelt period, from peak SWE to SAG. POR refers to the snotel's entire period of record.


Upper Taylor Snotel has a short period of record (since WY 2010), and is not presented here yet.

See our Snotel Dataset page for downloadable Excel files for each CODOS site, and an "All CODOS Sites Aggregated" Excel workbook containing spreadsheets for Water Years 2006-2017 and a summary of all years combined.
