7.4 Diagrams <br />In addition to tables and graphs, BehavePlus wiII create diagrams for four variables: fire <br />characteristics chart in SURFACE, wind/slope/fire spread directions in SURFACE, point <br />source fire shape in SIZE, and the shape of a fire after suppression action (successful or <br />not) in CONTAIN. Diagrams are generated by selecting them from the list of output vari- <br />ables for the module. Diagrams can aid model understanding and interpretation. <br />Diagrams are produced for values in the output tables. Therefore, if only graph output is <br />selected, diagrams will not be produced. All of the diagrams for a single run use the same <br />scale. It is generally not good practice to request too many diagrams in a single run. Fig- <br />ure 50 shows table output and four associated diagrams. In this case, fire shape diagram <br />was chosen as an output from the SIZE module. <br />E *M behawPW 5.0 1 Fri, May 07, 2010 at 13.5931 <br />Inputs: SURFACE, SIZE <br />Desceptian a Pample Fire Shape Diagram <br />Fuel/Vegetatiom SnrfaceT7udeastoty <br />Feel Model <br />Aid 110iutme <br />Dead Fuel Moistwe <br />Live Fuel UoMm <br />Weather <br />MidilmYie Wind Speed <br />Dire&m of Wind Vector (from tVslope) <br />Terratu <br />FIR <br />Slope Steepness <br />ElapsedIrkne <br />W1z <br />Page 1 <br />% <br />6 <br />V- <br />N 7S <br />nA <br />M12 8 <br />4e8 <br />a 190 <br />% <br />a lic 50 <br />h <br />all <br />Run Optiom Notes <br />Mommun rehAle effective wind speed 16& IS imposed [SURFACE]. <br />Ca6Culations are only for the direction of v=im m spread [STWAC.E]. <br />Firdme ic* fiat a lengh, and spread distance are always <br />for the direction of the spread calculations [SURFACE]. <br />Wind and spread directions are degrees clockwise from upslope [SURFACE]. <br />Di upon of the wend vector is the direction the wind is pushing the En [SURFACE]. <br />Output Variables <br />Surface hate of Spread Ww&nu4 (Wh) [SURFACE] <br />Flame LftVh (k) [SURF'AC'E] <br />Direction ofMa>rinm Spread (from upsbga) (deg) [SURFACE] <br />Figure 50—Fire shape diagram was selected as an output variable for the SIZE module.
