Thanks for the input Eric. One thing that we need to consider with this stream is that during times of heavy flow, some quite large rocks are tumbled down the...
Hi Randy, Nice idea and theory is reasonable on the surface. There are, however, some physics problems to deal with. To make water run uphill you need to...
Randy, In the design of any diversion it is best to figure a way to be able to get to the water but direct and route the debris flows past your pipe box etc....
