Piped HGL Drainage Design Create piped drainage network designs and check existing designs. Features: Hydraulic Grade Line (HGL)Rational MethodTrial designs automatically generated at the press of a buttonTimes of concentration accumulated automatically and considered in the design flowsChoice of Manning’s or Colebrook-White friction coefficients Automatically: Extract profiles from design and existing surfacesDetermine catchment areasConsider multiple run-off coefficients and areas for all pitsDetect underground obstructions Interactively, graphically, design: Pipe invert levelsPipe sizes and slopesPipe coverDrops through pits Change any of the above and immediately compute: Pipe capacityFlow velocityPipe adequacyHydraulic grade line Generate reports showing: All the input dataAll the resultant design informationSetting out data for drainage network constructionPlan plotsProfile plotsPit schedules The current version of HGL Drainage Design is 9.13.We also have a similar Sewer Design module.
