Many a mine needs to control erosion in the surface water channels. If the mine is blessed with an abundance of good quality rock, riprap may be the most economic approach to limiting erosion. The best manual freely available on the web, in my opinion, is the California Bank and Shore Rock Slope Protection Design - Practitioner’s Guide and Field Evaluations of Riprap Methods.

Other sources of information available on the web include: Design Manual, Streambed Degradation and Streambank Widening in Western Iowa. Also from Iowa, published in 2006, so looking fresh and up-to-date is Design Guide and Construction Specifications for NPDES Site Runoff Control. The U.S. Department of Transportation in 2001 published the Urban Drainage Design Manual.

Of course there is a computer code that does it all. The first I found is called Rip-Rap.

With these three design manuals by your side, I suspect you could easily upgrade your mines surface water management facilities so that there is no potential for sediment to leave your site and impact downgradient, offsite receiving waters. It is good to know that such volumes are freely available. But when I tried to get deeper into the topic, I found that the American Society of Civil Engineers (ASCE) has a lock-grip on publications on the topic. You would have to pay to get these publications, so my advice is avoid them. The best information in them is probably already incorporated into the manuals the links to which I have already provided. Good luck and let me know how your surface water management studies work out.
