Stormwater Part 1

Summary:

Part 1 of the Stormwater Drainage Course includes the skills required to complete a minor stormwater drainage design

Prerequisites:

Experience in 12d Model with completion of either the Two Day Design Basics Course or the One Day Survey Basics Course. In some cases, working through the ‘Getting Started for Design’ Manual or ‘Getting Started for Surveying’ is sufficient – enquire upon booking.

Course Content:

W01: Network Design

• Trainees will start from creating a super tin to use with the drainage design
• Create (using templates) and edit a 12d drainage string and import designs from CAD
• Use the powerful network editor for pipe invert alignment including detecting and avoiding service clashes
• Link structures to the roadway design for structure alignment and construction levels/setout
• Additional techniques to calculate structure coordinates with grate and cover elevations

W03: Rational Hydrology

• Review default hydrology methods for determining C and tc
• Set multiple catchment areas per inlet structure via direct input and catchment polygons
• Determine time of concentrations from length – slope strings

W02: Hydraulic Grade Line Check

• Parameters for determining energy losses in pipes
• Pit pressure loss Coefficients (K) in 12d Storm analysis
• Culvert design with inlet control calcs
• Size pipes and box culverts

W04: Reporting

• Produce detailed hydrology, hydraulic and construction setout reports
• Produce drainage plan and long section drawings with user defined data, pipes as linestyles and manholes as symbols
