Protection work Connecting Drain to River 2

[dcnnng]

Any expert please advise and where can I obtain the details of the connection protection work for a drain discharging to a river. Your advise and assitance shall be very much appreciated. Thank you!

Could you add a little more detail? What is drained? What type of discharge to a stream or river and what kind of permits are in place? Some discharges are allowed and protection is not needed. However, discharging a wastewater or water from a process might need different methods for different applications.

Not to mention different river characteristics, flood elevations, currents, sediments, bank stability...

The outfall drain is 1.2m wide x 1.7m depth discharging normal urban surface runoff stormwater. The discharging drain is perpendicular to the receiving river of 40m wide and the discharge point is about 500m from the river mouth/sea. High tide is +1.7m and the drain IL is +3.6m. The protection work for the connection of drain outfall and receiving river is bascially to prevent erosion of the river earth bank of about 50 deg measuring from horizontal. I hope that this info is adequate for your advice. Thank you!

From the sound of the specific conditions/location you are dealing with here, I wonder if the U.S. Army Corps of Engineers (USACE, e.g. with work done/publications of their Vicksburg, MS facility) might be resources potentially helpful for the protection you need for this drain?

rconner, can you please give me the website where I can view the details. Thank you.

I don't know about "details", but I think a portal for the facilities/work I'm referring to may be

http://chl.erdc.usace.army.mil/

(e.g. notice "erosion control" etc. links)

also try this link for army engineering manuals, several of which deal with coastal engineering, flood control, drainage and erosion control, river hydraulics etc.
