Drainage Pipe Blockage
I am currently working on a project where I am required to design assuming 25% of pipe cross sectional area is blocked, and 25% of open channel area is blocked. Is there a way to model such a pipe blockage in the 12d drainage network editor? As for channels, I was going to model these using an overl...

Re: Dynamic Drainage Bypass Shape - Road Weir vs Conduit
Hi Owen,
In the major storm water actually backs up almost all the way to the kerb outlet, which seems to 'choke' the water a bit.
The HGL at the kerb outlet drops by about 100mm when conduit is used, compared to road weir which is higher.
Kind regards,
Allan

Dynamic Drainage Bypass Shape - Road Weir vs Conduit
Hello, I am modelling a bypass string between two nodes, the upstream node being a kerb outlet (see VicRoads Standard Drawing 2051) and the downstream node being at the base of a swale. The kerb outlet is at a sag point in the road. Would it be more appropriate to use 'road weir' or 'conduit' for th...

Drainage - Pipe capacity and area calculated incorrectly
In a drainage network I am currently working on, I have discovered a few pipes which do not have adequate capacity. This seemed strange to me since the catchment flows are quite low. Investigating the issue further, it appears that 12d is calculating the full pipe area (Af) incorrectly, and thus the...
