Purpose Sediment organic matter (SOM) influences settling and thus the rheological behavior of suspended particles by enhancing flocculation or reducing surface charges by forming organo-mineral complexes that facilitate particle–particle interactions in consolidating sediments. It was, therefore, assumed that the microbial degradation of SOM and its spatio-temporal variability would affect sediment rheological properties and...

This examination of milling capacity and timber use in the western United States summarizes changes in the region’s wood products industry and its ability to use trees of various sizes. Between 1986 and 2003, total timber-processing capacity in the West (excluding pulpwood and fuelwood) declined from 5.0 to 3.2 billion cubic feet annually, and capacity utilization decreased from 3.6 to 2.5 billion cubic feet. During 2003, 2.2...
