The samples were flow-weighted composites. We also obtained 24-hr time composite baseflow samples monthly for comparison. Hope this helps. My company is studying a 1,200-acre watershed on the east side of San Francisco Bay. It is essentially built out with some commercial use, quite a few apartments, and many homes ranging from bungalows to mansions.
Slopes are moderate for the east side of the bay.
We do know that silt, sand, and gravel do accumulate at the lower end of the system. Our measurements indicate that a wet winter can generate something on the order of 3,600 pounds per acre.
