11 Moisture Scenarios <br />A fuel moisture scenario is a set of fuel moisture values that represent moisture condi- <br />tions of surface fuel: 1-h, 10-h, 100-h, live herbaceous, and live woody fuel moisture. <br />Fuel moisture scenarios are analogous to fuel models—they package a number of val- <br />ues into a labeled set. The option of using moisture scenarios is available in SURFACE <br />Options... on the Fuel & Moisture tab (Figure 59). The moisture scenarios used by <br />Scott and Burgan (2005) to develop the set of 40 fuel models are provided with the pro- <br />gram. Moisture scenario D2LI, for example, represents low dead, fully cured herbaceous <br />fuel (1-h = 6%, 10-h = 7%, 100-h = 8%, live herbaceous = 30%, and live woody = 60%). <br />Similar to fuel models, a right -click on a moisture scenario code in the selection list gives <br />the option to View parameters. A window will open that shows the moisture values as- <br />sociated with each class of fuel (Figure 63). <br />'ichue� <br />Moisture Scenario d211 <br />Scenario Name d211 <br />Description DZL1 - Low dead, fully cured herb <br />(6,7,8,30,60) <br />Dead 1-h <br />6p ent <br />Moisture <br />Dead 10-h <br />7 percent <br />Moisture <br />Dead 100-h <br />Moisture <br />8 percent <br />Lave Herbaceous <br />30 percent <br />Moisture <br />Live Moody <br />60 percent <br />Moisture <br />Figure 63—Right-click the moisture scenario code in the selection list and select View parameters <br />to view values of the moisture scenario. <br />99.9 Custom Moisture Scenarios <br />As a user, you can also define and save your own moisture scenarios. For example, you <br />might want to define moisture values for the 901 and 971 percentile fire weather conditions <br />for a prescribed fire site. To create a custom moisture scenario, use a BehavePlus work- <br />sheet that includes the SURFACE input option of Moisture is entered by individual size <br />class. You need only to fill in the fuel moisture values on the worksheet and then click <br />File > Save as a moisture scenario. When naming a custom moisture scenario, it is a <br />good practice to include the values in the name for easy reference. <br />USDA Forest Service Gen. Tech. Rep. RMRS-GTR-249. 2010 75 <br />
