#HydroCloud Instructions

• Map:
• Graph: The graphing page. There are four graphs available:
  • Hydrograph: a plot of Stream Discharge on the Y axis measured in cubic feet per second (cfs). Time on the X axis. This graph also has a second graph below showing precipitation in mm over the same timeline. Stream discharge data come the USGS stream gage named in the top label. Precipitation comes from a watershed-averaged precipitation from NEXRAD stage IV precipitation estimates.
  • Flow Duration: a plot of all stream discharge measurements in cfs ordered by size, from largest to smallest. Stream discharge is plotted on the x axis in a logarithmic scale in scientific notation, so that "1e+2" equals 100 cfs and "4e+3" = 4000 cfs.
  • Histogram: __disabled.
  • Hyetograph: __disabled.
• Stats: The site statistics page. This lists each site that has been selected in the map view, along with some simple site statistics, including the USGS site # and the area of the watershed in square miles.
• ? (help): This will take you to this page.
