Landsat TM image showing sediment in the Gulf of Thailand at the mouth of the Chao Phraya River. Colors represent different concentrations of sediment. Sediment load in rivers can be affected by land-use practices and rainfall variations. The curving horizontal lines are “trails” of sediment stirred up by trolling fishing boats.
