Abstract

Replacement of wetlands by water and flats in the lower alluvial valley and delta of the Trinity River suggests that relative sea-level rise and reductions in sediment supply have rendered the fluvial-deltaic system incapable of maintaining sufficient elevation to prevent its submergence. The Trinity River transports the greatest load of suspended sediment of all rivers emptying into Texas bays (Longley, 1992a), and therefore, it has the greatest potential for delivering enough sediment to offset subsidence.
