I've got a hack for that, too :)Matt Kuchtahttps://www.blogger.com/profile/18168846490598155683noreply@blogger.comtag:blogger.com,1999:blog-18321380.post-13007451453514705002012-10-24T20:49:07.323-05:002012-10-24T20:49:07.323-05:00As usual, a clever hack.

Or, does it simply add more to the total flux. I suppose the only way to address that would require a method to measure the bank-erosion contribution. <br /><br />Fun!BrianRhttps://www.blogger.com/profile/04930245080333999989noreply@blogger.comtag:blogger.com,1999:blog-18321380.post-19555940541895978372012-10-22T18:09:35.211-05:002012-10-22T18:09:35.211-05:00Intermittent motion would be the easiest way to lo...Intermittent motion would be the easiest way to lower sediment flux for this design, I think. You could run the motor at higher voltage potential to overcome belt friction, but run it less often. That also brings in the possibility of computer control... pair that up with a flow controller and *bang zoom to tha' moon!*Matt Kuchtahttps://www.blogger.com/profile/18168846490598155683noreply@blogger.comtag:blogger.com,1999:blog-18321380.post-46491910353080279542012-10-21T18:32:03.676-05:002012-10-21T18:32:03.676-05:00Cool!

Add intermittent motion using an Arduino or whatever and you could get your rate lower. When we feed we have a mixing chamber of sorts into which the water and sed inflow go; force the two under a gate to create turbulence, and the media gets wetted and your "floaters" go away.Anonymoushttps://www.blogger.com/profile/16066285550739882631noreply@blogger.com
