The deltaic plain (32,000 km 2 ), through which the modern river cuts diagonally (Fig. 1), consists of vast wetlands and waterbodies. With elevations ranging from sea level up to 1.5 m, it is interrupted by natural levee ridges which decrease distally until they disappear beneath the marsh surface . The downdrift chenier plain of southwest Louisiana (8,000 kmZ) consists of marshes, large round-to-oblong lakes, and stranded, oak covered beach ridges known as cheniers (Howe et al. 1935). This landscape is the result of alternating long-term phases of shoreline accretion and erosion that were dependent upon the proximity of an active sediment-laden river, and a low-energy marine environment (Byrne et al. 1959).
