What is the appropriate slope for a drainage ditch?
Thread Content
Dear experts, what is the appropriate slope for drainage ditches? Are there any standards in this regard? I hope you can offer some guidance. Thank you

There is a SH 3094-1999 standard for the design of drainage ditches in petrochemical industries. One of the statements is that \"the minimum longitudinal slope should not be less than 0.2 percent.\"
Generally, the slope of drainage ditches is 3% to 5%
2.5 percent, I think that’s fine; it depends on the length
I’ve worked on projects with a scale of 1.5 and 2.5; it mainly depends on the construction quality. Some teams are able to meet the overall requirements, but there is water accumulation in certain areas…
