Taylor and Francis Ltd Mathematical Modelling of Sediment Transport and Deposition in Reservoirs 2021 Softbound by Cigb Icold
As reservoir sedimentation has proven to be a serious problem in South Africa, research in this field has been ongoing for more than 70 years. This publication emanates from extensive research which has been undertaken over the past 30 years with the support of the South African Department of Water and Sanitation as well as the South African Water Research Commission.A great deal of information has fortunately also been obtained from China.Given the universal nature of hydraulic formulae it is not surprising, yet gratifying, that Chinese and South African data generally conform to the same mathematical relationships. This indicates that these relationships should be applicable in other countries as well. Much of the information contained here has been condensed from a more comprehensive publication.This ICOLD Bulletin follows on Bulletin 115 "Dealing with reservoir sedimentation", which gave guidelines for management of reservoirs to limit sedimentation. The guidelines on mathematical modelling of sediment transport dynamics in reservoirs in this document can be used during the planning and design of new dams, as well as for the management of existing dams.Comme la sedimentation dans les reservoirs s'est averee etre un probleme serieux en Afrique du Sud, la recherche dans ce domaine est en cours depuis plus de 70 ans. Cette publication emane de la recherche etendue qui a ete menee au cours des 30 dernieres annees avec l'appui du ministere sud-africain de l'eau et de l'assainissement, ainsi que de la commission sud-africaine de recherche sur l'eau.Un grand nombre d'informations ont egalement ete obtenues de la part de la Chine.Etant donne le caractere universel de formules hydrauliques, il n'est pas surprenant, mais tres gratifiant, que les donnees chinoises et sud-africaines se conforment generalement aux memes relations mathematiques. Ceci indique que ces relations devraient etre applicables dans d'autres pays egalement. Une grande partie de l'information contenue ici a ete condensee a partir d'une publication plus complete.Ce bulletin CIGB fait suite au bulletin 115 "Traite sur la sedimentation dans les reservoirs", qui a donne des directives pour la gestion des reservoirs en vue de limiter la sedimentation. Les directives sur la modelisation mathematique de la dynamique de transport des sediments dans les reservoirs de ce present document peuvent etre utilisees lors de la planification et la conception de nouveaux barrages et pour la gestion des barrages existants.
