S11: Critical Conditions for WY2003 CH3D-FC (91x96 grid)
Result_08_91x96 (Simulation Completed on July 1, 2006)

 

Summary

This page summarizes the results of selected nodes (Canary Nodes) from the CH3D-FC 91x96 grid. A group of nine contiguous nodes was selected for each Canary Nodes (the colored cells in the Canary Nodes figure). For each group of nine nodes the time series of simulated FC concentrations (colored lines) and observed FC measurements (red circles) are displayed (cfu/100 ml) in the plots listed below. The water quality limits for the shellfish harvesting bacteria criteria of 14 cfu/100 ml (geometric mean) and 43 cfu/100 ml (ninety percentile) are also displayed.

 

Groups

The data plotted are the time series of simulated canary nodes for the selected group and the observed data from the station(s) at or closest to the group.  The default is to plot the concentration of the surface layer for each of the nine nodes

Spreadsheet of canary node groups and coordinates: CanaryNodes.xls

Use the ENVVEST Spatial Data Viewer to find the id’s of individual nodes (select GENERAL tab -> Highlight Canary Node: “91x96 Grid” to id individual nodes).

Sheetname

Explanation

Units

dailymax

Simulated maximum daily FC concentration from Oct 1, 2002 to Sep 29, 2003 (364 days) columns A:I are surface nodes, Colums J:R are depth-averaged nodes.

cfu/100ml

m30day

Moving 30 day Geomean of daily max FC from Oct 30, 2002 to Sep 29, 2003  (334 days) columns A:I are surface nodes, Colums J:R are depth-averaged nodes (data were transformed by log10(FC+1) to calculate geomean).

 

cfu/100ml

EX14

Compares moving 30-day Geomean to 14 cfu/100, cell has 1 if FC>=14, column sum is number of days for exceedance.

 

true/false

gridAVG_surf

Surface nodes: The 30-day rolling geometric mean in the highest 1/2/3/4/6/9 grid cells, Col A is grid with max levels, Col B is avg of top 2 grids, Col C is average of top 3 grids, Col D is average of top 4 grids, Col E is average of Top 6 grids, and Col F is average of all 9 grids

 

cfu/100ml

fc_target_surf

Surface nodes: The fraction reduction needed as 1 - 14/geomean; negative value means no reduction needed (if geomean=0, -1000 is result); Col A is result for top 3 grids, Col B is result for top 4 grids, Col C is result for Top 6 grids, and Col D is result for all 9 grids

fraction reduction needed if positive

gridAVG_depthavg

Depth-averaged nodes: The 30-day rolling geometric mean in the highest 1/2/3/4/6/9 grid cells, Col A is grid with max levels, Col B is avg of top 2 grids, Col C is average of top 3 grids, Col D is average of top 4 grids, Col E is average of Top 6 grids, and Col F is average of all 9 grids

 

cfu/100ml

fc_target_depthavg

Depth-averaged nodes:The fraction reduction needed as 1 - 14/geomean; negative value means no reduction needed (if geomean=0, -1000 is result); Col A is result for top 3 grids, Col B is result for top 4 grids, Col C is result for Top 6 grids, and Col D is result for all 9 grids
