APPENDIX DRules of Thumb

Rules of ThumbSeveral Rules of Thumb worksheets are provided to aid designers and inspectors in determiningand verifying the quality and quantity of various erosion control items. These are especiallyuseful when verifying the application rates of various mulch and hydraulically applied products.Rules of Thumb includes the following: Example Seed TagsSlope Inclination ConversionsMetric ConversionsSediment Trap Sizing SpreadsheetI-D-R Curve Zone MapStraw Mulch Application WorksheetHydraulic Application EquationsWood Fiber Mulch Hydraulic Application WorksheetSeed / Fertilizer Hydraulic Application WorksheetHydraulic Application Example Problems

Rules database is the basis of the rules engine and it is a collection of rules files which are established by rules engine. Rules database is maintained by rules management and it is used by rules engine. (5) Rules Matching The first step is modelling with rules files in rules database.
