Sediment oxygen demand and its effect on dissolved oxygen in a cutoff meander of the Kaskaskia River

This study was designed to assess the relationship of sediment oxygen demand and dissolved oxygen in a cutoff meander of the Kaskaskia River. The results of the study should be useful to agencies such as Departments of Conservation, Corps of Engineers and the Environmental Protection Agency when assessing the impact of stream channelization on cutoff meanders of channelized streams. Cross-sectional profiles were used to determine area and total water volume in the meander. When stagnant or no-flow conditions prevailed, anoxic conditions created by sediment oxygen demand were observed in a significant part of the water in the meander. When no-flow conditions prevailed during summer months, as much as 25% of the water in the meander became anoxic while 65% fell below 5.0 mg/l. Sediment oxygen demand rates were more closely related to temperature than to sediment consistency or benthic macroinvertebrate numbers. Ambient sediment oxygen demand measured during the summer was almost three times greater than demand measured during the fall. While sediment oxygen demand in the channelized portion of the river was higher than in some stations in the meander, reaeration resulting from flowing water in the channel was sufficient to prevent anoxic conditions from developing.U.S. Department of the InteriorU.S. Geological SurveyOpe

Measurements of Sediment Oxygen Demand Characteristics of the Upper Illinois Waterway

Oxygen demand characteristics of bottom sediments for a 113-mile reach of the Upper Illinois Waterway were measured in situ at 22 locations in order to assess the effects of such demand on the dissolved oxygen resources of the overlying water. For the measurements of sediment oxygen demand (SOD), a bottom sampler was specially designed to entrap and seal a quantity of water at the river bottom. Changes in dissolved oxygen (DO) concentrations within the entrapped water were recorded by a DO probe fastened in the sampler. SOD values for 20 undisturbed bottom locations ranged from 0.56 to 5.00 grams per square meter per day (g/m2/day), and values at 2 disturbed locations were 6.45 and 8.08 g/m2 /day. The oxygen demands of sediments in many parts of the waterway are sufficiently high to impose a significant demand on the DO content of the overly ing water. In addition to SOD measurements, 172 bottom samples were collected, described in detail, and analyzed for percent organic and dried solids content. Expressions for the relationship between these percentages and the SOD rates were developed and used to estimate probable SODs at the various sampling sites. Subsequent charts of the river bed depict the ranges of SOD values useful in engineering analyses of the waste assimilative capacity of the Upper Illinois Waterway.publishedpeer reviewedOpe
