English term
spill drift
English
Tech/Engineering
Construction / Civil Engineering
I have a text that I'm translating (into Urdu) where the following three terms appear in two consecutive sentences.
- spill drift
- spillover
- spillway
The topic of discussion is a natural water body (a lake or such like). As I understand it the three term have been used synonymously.
I know what a spillway is, but I haven't heard the term "spill drift" used like this.

spread of spilled liquid
I think it means, quite simply, the drift of the spill - i.e. the direction the spilled liquid moves in and how it spreads after it is spilt.
It doesn't seem to a formally defined term, just a combination of words that expresses a concept in a compacy and efficient way.
This seems to be borne out by the context of the citations below:
see under 2.2 Hydrology of this document
http://www.ecy.wa.gov/programs/spills/preparedness/GRP/Snake...
also see
http://www.osti.gov/energycitations/product.biblio.jsp?osti_...
Planning involves time study considerations of spill drift, crew reaction time, current measurement and calculation, and correlation of time studies.
where it says:
There is usually a perceptible current in both the Snake and Clearwater Rivers at the Lewiston-Clarkston area. Flow will have a perceptible affect on spill drift. Perceptible current will gradually disappear as a spill progresses downstream toward the next dam. As the spill travels downstream, the wind will begin to affect spill drift far more than the current will.

Hope this helps!

Discussion
Spillway and spillover channel are roughly equivalent, but I haven't encountered "spill drift" in any related context. And I'm not very hopeful now :-(
@Stephanie: Can't quote I'm afraid. The terms have been used synonymously. I'm just trying to check with a wider audience whether anyone had encountered 'spill drift' in the context of the other two terms (perhaps in some technical literature).
I can only speculate that if it refers to water that has spilled over the edge of the lake (as in "spill over" and "spillway"), it could mean drifting down sloping ground under the influence of gravity, or conceivably permeating the ground and spreading or "drifting" through the subsoil. But I have no evidence at all to support this. Let us hope that someone more knowledgeable appears.
