WebMockus (1949) and the soil–vegetation–land-use (SVL) complex of Andrews (1954) has yielded the SCS-CN method (Rallison and Miller, 1982) described in the Soil Conservation Service National Engineering Handbook Section 4 (SCS, 1956, 1964, 1971, 1985). The SCS-CN method has been the focus of much discussion in recent hydrological literature. WebWhere was the Red Sea of Exodus? Exodus records that the waters of the Red Sea (or Reed Sea) opened up to deliver Israel and plummeted down to destroy their Egyptian pursuers. But if the Red Sea cannot be located, can we trust the claims of the Bible? Some have suggested relocating the events. Others suggest they never happened at all. In …

"WebService (SCS) in 1954 (now known as the NRCS). The NRCS-CN method introduced the concept of a CN, which accounts for soil characteristics, infiltration rate, vegetation cover, and land use (Hawkins et al., 1985; USDA-NRCS, 2004; Huang et al., 2006; Ebrahimian et al., 2012).

WebIn the SCS method, the time lag tL for the catchment is computed using the following expression: (4.131) where tL is the catchment time lag (h), L is the length of the main stream (m), CN is the SCS runoff curve number, and S is the catchment average slope (m/m). The selection criteria of the CN value are described in NEH-4. WebThe SCS Runoff Curve Number (CN) method is described in detail in NEH-4 (SCS 1985). The SCS runoff equation is Q= ( P Ia ) 2 ( P Ia ) + S [eq. 2-1] where Q P S Ia = runoff (in) = rainfall (in) = potential maximum retention after runoff begins (in) and = initial abstraction (in) Initial abstraction (Ia) is all losses before runoff begins.
