Description :
Channel cross-sectional changes since construction of livingston Dam and Lake Livingston in 1968 were studied in the lower Trinity River, to test theoretical models of channel adjustment, and to determine controls on the spatial extent of channel response. High and average flows were not significantly modified by the dam, but sediment transport is greatly reduced. The study is treated as an opportunistic experiment to examine the effects of a reduction in sediment supply when discharge regime is unchanged. The multiple modes of adjustment are predicted by the unstable hydraulic geometry model.
