Report on on sediment transport modeling of reach scale geomorphic processes: "[The] study investigated the use of a modeling strategy to predict channel adjustment and floodplain accretion in the lower San Antonio River. The modeling strategy was employed in three subbranches with different channel characteristics to capture a range of possible geomorphic responses in the river and validated with empirical observations where possible. Using the modeling strategy, flow simulations of prescribed in-stream flows can provided initial insights into the response of the river" (p. 2).
