CETN IV-20
September 1999
several equations are taken directly from CETN-IV-15 (Revised September 1999) and
CETN-IV-16.
Step 1: Develop a Conceptual Sediment Budget. Determine the conceptual sediment budget
by delineating sediment budget cells, indicating sediment-transport pathways, and entering place
holders for volume and placement rate data. Within SBAS, the conceptual sediment budget
(Figure 3) is designed to encompass all the cases discussed above. The lengths of the southern or
updrift cell and the northern or downdrift cell are equal: 4,500 m. The length of the inlet cell is
1,000 m.
