De Vriend, H.J. (author)After the study of fully developed and developing steady laminar flow in curved channels of shallow rectangular wet cross-section (see earlier reports in this series), steady turbulent flow in such channels is investigated as a next step towards a mathematical model of the flow in shallow river bends. A mathematical model is developed for this...report 1979

De Vriend, H.J. (author)As an intermediate step between earlier investigations on fully developed laminar flow in curved channels of shallow rectancular wet cross-section and the mathematical modeling of turbulent flow in river bends, a mathematical model of developing laminar flow in such channels is investigated. The most important assumptions made in addition to...report 1978

De Vriend, H.J. (author)Uitgaande van de Reynoldsvergelijkingen met de bijbehorende randvoorwaarden wordt een vereenvoudigd wiskundig model afgeleid voor ondiepe bochtige rivieren. met als voornaamste uitgangspunten: - de vertikale afgeleiden van de snelheden zijn groot t.o.v. de horizontale - de schuifspanningseffekten overheersen de traagheids- (advectieve) effekten....report 1976
