Book Description
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 development and characterization of hydraulic geometry were employed to spatially distribute climate and hydrologic processes in unmeasured locations. Parameterization techniques sought to include known spatial information for tributaries such as soils information and slope, and then parameters were scaled up or down during calibration to retain the spatial characteristics of the land surface in un-gaged areas. The hydrologic and suspended sediment calibration focused more heavily on the Sacramento River rather than the tributaries. Calibration and validation of the Sacramento River ranged from "good" to "very good" performance based upon a "goodness-of-fit" statistical guideline. Model calibration to measured sediment loads were underestimated on average by 39% for the Sacramento River, and model calibration to suspended sediment concentrations were underestimated on average by 22% for the Sacramento River. A slight decreasing trend is evident in the modeled suspended sediment from 1958-2008, and is statistically significant (p

Book Description
Sediment is usually considered an integral part of water quality in river systems. Understanding sediment transport mechanisms is crucial for studying the fate and transport of sediment-facilitated contaminants. In order to understand sediment transport processes, a channel network model, CCHE1D, was first applied for a sensitivity analysis on simulation parameters and options at the Goodwin Creek watershed, Mississippi. The sensitivity analysis evaluated Manning's roughness coefficient, bed sediment class distribution, bankerosion and different sediment transport capacity formulas by comparing hydrology and sediment results with original data from model developers. A simulation model of the Cache Creek watershed, California was then developed to study the streamflow, and to estimate downstream sediment yield in the main channel between Rumsey and Yolo. A nonlinear relation between flow discharge and sediment yield was obtained by the sensitivity analysis, which also showed that different sediment size class had different sensitivity level towards simulation parameters and options. The sensitivity analysis results suggested that having sufficient and detailed sediment data, even in a short period of time, could be beneficial for obtaining accurate sediment yield estimation downstream. The simulation model at Cache Creek watershed was calibrated for hydrology with r2 value of 0.78; Nash-Coefficient of 0.78 and sediment yield with r2 value of 0.70; Nash-Coefficient of 0.70. It was then validated for hydrology with r2 value of 0.95; Nash-Coefficient of 0.93 and sediment yield with r2 value of 0.59; Nash-Coefficient of 0.57. The model was then applied to reconstruct 10-year suspended sediment data at Yolo based on available hydrology data and limited short-term sediment data. The results can be useful for studies at Cache Creek Settling Basin, which are important for controlling sediment entrapment and preventing spread of mercury contamination to San Francisco Bay-Delta area.
