how to estimate the amount of erosion wastes in a road project?

how to estimate the amount of erosion wastes in a road project?

(OP)
hi,

this is my first participation to the Eng-Tips Forum, so pleas grant me the privilege of the mistake :D .

I'm a new-born engineer with a littel more than a two-months expirence in my first job as a road project studies engineer.

my firm has a project that requires a prevision of the budjet that erosion wates treatment should require for somthing like ten to fifteen years ahead.

the area of the project is known as muddy and with very frequent slope stability problems.


my question is : "is there any  way, precise enough to build an estimation (price) out of it, to know how much erosion wastes the road will be receving per a year for a given periode?"

this was my best shot in being clear without your assistance! pleas ask quastions so I can help you help me :D.

thank you for your understunding.

tell me!

RE: how to estimate the amount of erosion wastes in a road project?

you need - geotechnical study, hydrology study plus a grading plan for the road and then with that data you can estimate rates of erosion and propose methods to control it. With that you can estimate the cost of the erosion. None of the methods are considered very precise.

you can google USLE, RUSLE to find a couple methods for sediment production.

.

The WEPP software application forestry version (WEPP:Road) should be able to process the analysis you are describing. LISEM will also work. It is a bit more complicated.

I've surely come to the right place :D.

thanks guys for your outstanding responding time. I'll start with that and my guess is that it should be fine.

best regards.

Maybe a less technical approach...

You say that the site is prone to 'frequent stability problems' - has a slope failure occured that you can measure the sediment produced?  Maybe the simple way would be to look at what has happened in the past and use that as a way to budget for the future.
