Abstract: A model of sedimentary oxygen demand (SOD) for a sediment bed of finite length is presented. The responses of diffusive oxygen transfer in turbulent flow above the sediment surface and of microbial activity inside the ...

Abstract: The mixing of temperature‐stratified lakes and reservoirs by means of buoyant jets, which are created by withdrawing water from one layer and injecting it into another layer, is examined. The physical features of the thermal ...

Abstract: A turbulent buoyant jet in a stratified ambient fluid is investigated. The integral analysis approach is used and extended. By applying the similarity hypothesis for velocity and temperature profiles and deriving an ...

Abstract: Lake ice and lake temperatures depend on climate and lake morphometry. Simulated lake ice and lake temperature characteristics of 10 large lakes in Minnesota were therefore related to climate parameters, geographic location, ...

Abstract: Experiments are conducted in a horizontal laboratory channel with slightly diverging walls to simulate buoyancy driven plunging flow. A temperature difference between inflow and downstream ambient provides the density ...

Abstract: The flow considered herein is a two‐dimensional negatively buoyant flow from a shallow channel over a sloping bottom (mild or steep) into a well‐mixed reservoir. For the analysis, a set of integral equations, in particular ...

Abstract: Ice-on and ice-off dates, ice cover duration, and ice thicknesses for four lakes in the United States and one lake in Canada were simulated. The model used is a one-dimensional, deterministic water quality model that ...

Abstract: This paper deals with artificial mixing of naturally temperature‐stratified water bodies, such as lakes, reservoirs, and ponds, by selective withdrawal and jet reinjection at a different depth. The effects of jet orientation ...
