The first two hydrology scenarios produced in conjunction with the Initial CERP Update effort were released in late September 2003. The 2000 Existing Conditions Base, referred to as "2000B1," was produced by the South Florida Water Management Model (SFWMM), upgraded to version 5.0. The second scenario was produced by the Natural System Model Version 4.6 Final, referred to as "NSM_v4.6F". Detailed information concerning these scenarios may be found on the web page containing the performance measure viewer (select "Alternative or Scenario Descriptions").

Caveats concerning NSM hydrology scenarios and ATLSS models

When ATLSS models are used to compare SFWMM hydrology scenarios to NSM scenarios, a number of caveats must be considered.

Time-series graphs of yearly SESI values averaged over indicator regions for
2000B1 (2 Mile) versus NSM4.6F
NOTE: Considering the Ridge and Slough indicator regions as a single group masks divergent trends in the WCAs versus the Slough system to the south; therefore, this group has been subdivided for these analyses into (1) indicator regions that fall in the WCAs (WCA-2 and WCA-3) and (2) those that fall in Everglades National Park.
