Benthic community-mediated sediment dynamics

Benthic Biological Community Responses to Sediment Loading in Experimental Stream Mesocosm Channels

Benthic Invertebrate Community Structure

Fundamental to the scientific method is the use of controls or control conditions against which results obtained under test conditions are compared. In field studies, all variables cannot be controlled and replicates cannot be randomly assigned to treatments, so an attempt is made to choose test and control conditions (often represented by different sites) that are as similar as possible; the v...

Community Sediment Transport Model

The goal of this project is to produce an open-source model that couples hydrodynamics (circulation and waves), sediment transport, and morphodynamics. The need and value for such a model has been well established by previous NOPP-supported planning efforts (Sherwood et al., 2000; 2002) and the feasibility of the proposed approach has been demonstrated by incorporation of sediment-transport and...

Bioavailability of Sediment-Associated Contaminants to Benthic Invertebrates

Benthic Studies in Buzzards Bay. I. Animal-Sediment Relationships

During October and November 1955 a bottom faunal study was undertaken at 19 localities in Buzzards Bay, Massachusetts. The number of animals ranged from 1,064 to 12,576/m2 with a mean number of 4,430. In comparison with certain other areas these numbers appeared small and seemed to be due to the relatively low concentrations of chemical nutrients and modest primary production of the region. Two...
