Abstract Details

2006, Master of Environmental Science, Miami University, Environmental Sciences.
Thirty sediment samples collected from three trenches in the Great Miami Riverbed during low-flow conditions were characterized to determine riverbed variability. Wet-sieve analysis was used to characterize the riverbed sediments. The riverbed was a mixture of cobbles, gravel, sand, silt and clay. Median grain-size (d50) ranged from 4.50 mm to 70.0 mm, with an average of 22.6 mm. Uniformity coefficient (Cu) ranged from 8.53 to 41.7 with an average of 27.3, indicating that the samples were all poorly to very poorly sorted. The amount of silt plus clay in the sediments ranged from 0.48 to 2.76 %, with an average of 1.34%. The shallow and deep sediment samples were not significantly different. Regression analyses showed that the amount of silt plus clay in the sediments decreased with distance from the riverbank at a p-value of 0.001. Hydraulic conductivity was estimated from grain-size analysis data using the Hazen and Shepherd methods. These overestimated hydraulic conductivity by several orders of magnitude probably because the sediments were much coarser than were intended by either method.
