← GeographyWhich outcome results when rapid river levee aggradation slows?
A)Increased channel meandering initiates nearby✓
B)Floodplain soil salinity decreases rapidly
C)Drainage networks become deeply incised
D)Base flow increases proportionally riverside
💡 Explanation
Increased channel meandering initiates nearby because reduced levee creation allows Floodplain Avulsion. Stream Gradient accommodation lags rather than baseflow increasing; this is because the aggradation rate dictates stream dynamics; therefore, the avulsion initiates the meandering rather than alternatives.
