Craig if there were no baffles, would not gravitational sorting still occur as soon as the sluice water begins to slow down after leaving the box? When I see gully erosion in the glacial till underlying most of the cropland here, the rocks and pebbles are at the top, then the sands, and then the silts, clays, and crop residue at the bottom.
Isn't that why the water in the streams and rivers below turn muddy and why the Mississippi Delta has grown so large since agriculture began in its watershed?
Whatever. I just feel better eating steel than I do lead when I wolf down those tasty grilled dove breasts wrapped in bacon.
So which is it... are the silts and clays and other fines at the bottoms of erosion cuts???... or do they get washed away and end up in places like river deltas???? Or do you get to have it both ways in the Twilight Zone?
Regardless, the forces behind deep erosions are not what takes most of our small dense lead spheres deeper into the soil over time. Fast moving water does not float large rocks and stones to the top. They are simply too heavy to be moved as easily, and get left behind.
Apparently it's all about what makes you feel good that drives your beliefs and conflicting observations. Does that bacon wrapped around the dove breasts make you feel like your arteries are plugging up with cholesterol plaques? I'd bet the science says more people are at risk from saturated fat induced coronary heart disease than they are from possibly swallowing a stray lead shot pellet, and having it pass out of their digestive tract. And I think most dentists would see greater job security from patients biting into steel versus lead.
Chew gently!
