Location map of Sacramento Valley portion of the Sacramento River Basin, CA indicating: model domain (red boundary), gages and dams used as boundary conditions and for model calibration. RB = Sacramento River at Red Bluff, HC = Sacramento River at Hamilton City, BC = Sacramento River at Butte City. Major surrounding mountain ranges are labeled and the total drainage area of the Sacramento River is indicated (yellow of inset).

A watershed model of the Sacramento River Basin of northern California was developed to simulate the streamflow and suspended sediment transport to the San Francisco Bay Delta for fifty years (1958-2008) using the Hydrological Simulation Program – FORTRAN (HSPF). To compensate for the large model domain and sparse data, rigorous meteorological deve...

... western side is predominantly pyroclastic debris and lava flows, and the lowland areas are primarily alluvium. The land use within the study domain is comprised of over 50% scrub and grasslands, nearly 30% forest, 5% each urban and cultivated crops, 3% pasture and hay, 1.3% is comprised of water or wetlands, and 0.5% is barren land (Figure 1) (Fry et al., 2011). ...

... temperature index or "degree-day" method calculates most snow processes and calculates heat exchange using air temperature and an empirical degree-day factor (Rango and Martinec, 1995), and therefore requires fewer meteorological inputs than the energy balance approach. HSPF produced snow in the HRUs with high elevation, and modeled snow was compared to the California Data Exchange Center (CDEC) (cdec.water.ca.gov) snow stations ( Figure 1) ( Table 7). was close to observed SWE in the smallest basin that had measured data available ( Figure 6). ...

... ratio of modeled to observed sediment loads was 0.97 for Sacramento River at Hamilton City, and 0.53 for Red Bluff and Butte City. Annual sediment loads showed a high correlation of R 2 values (0.825 -0.992) between observed and modeled ( Figure 14). Overall, the sediment loads were consistently under-simulated ...
