Land-use histories that change riparian vegetation density, thereby changing floodplain resistance, may affect channel sinuosity. On this reach of the Sacramento River (California), sinuosity decreased from Ω = 2.2 before 1874 (blue) to Ω = 1.4 by 1898 (white) after natural vegetation was replaced with planted orchards. For historical and present river conditions relative to data in Fig. 4B and Fig. S4.
