The “Dynamic Drainage” is a one day training course. It’s an extension for 12d drainage users and covers the modelling of storage systems such as basins or tanks. Diverging flows and sections cut into the design tin further show the tools available to accurately model the complete system.
Dynamic Drainage
This “Dynamic Drainage for Modelling Storage” course is an extension for 12d drainage users who have already attended the Stormwater Drainage (Parts 1 and 2) and wish to further extend their design drainage skills.
The course continues on from the Rational Hydrology method to rainfall runoff models and dynamic flow in pipes (St Venant unsteady flow equations).
Prerequisites: For experienced 12d Model Users only. You must be fully familiar with the Water Network Editor (WNE) and know how to design drainage networks in 12d Model.
Completion of the “Introduction to 12d Model” and Stormwater Drainage (Parts 1 and 2) is required. By booking a course, you affirm that you meet the requirements for 12d Model training courses. Check on upcoming courses at bottom of page.
Participants learn to:
Hydrology
- Rainfall runoff methods discussed will vary with regions (SCS, or ILSAX)
- Moving from rational “C” to Soil types
- Additions to the 12d rainfall file including ARR2019
- Reviewing graphical outputs
Hydraulics
- Modelling diverging flow conditions
- Bypass flow using surface flows with section shapes cut from the design tin.
- Time series for tail water conditions.
- Modelling natural channels using section shapes cut from the design tin.
Detention Basin Design
- Estimating storage to meet the pre development discharges,
- Creating detention basins and extracting elevation area curves from the tin,
- Multiple outlets design (combining spillway, control pipe, orifice)
Storage Tank Design
- Estimating storage to meet the pre development discharges via discharge control pipes and orifice plates.
Infiltration Tank and Swale Design
- Using discharge rating curves to model infiltration in swales and tanks.
