West Sacramento, California

Rocko is the Senior Fluvial Geomorphologist at CFS and is responsible for leading studies and analyses of hydrologic and geomorphic processes that shape fish habitat. Rocko has more than 17 years of experience analyzing hydrology, hydraulics, and sediment transport associated with projects that restored fish habitat, aided flood control, modified hydrology, removed dams, and stabilized stream banks, and he is skilled in a wide range of field methods and analytical tools employed in leading studies of fluvial geomorphology. These include surveying; remote sensing; 2D modeling of flow, sediment, and habitat; GIS analysis; hyporheic exchange; steam habitat design; and fish passage assessments.
