2-D sediment transport simulation in natural streams Botev, Ivan Botev Ivan Tamai, Nobuyuki Tamai Nobuyuki Kawahara, Yoshihisa Kawahara Yoshihisa open access bed evolution numerical simulation natural stream 510 River bed evolution during a flood event is modeled in a quasisteady approach using a 2-D depth-averaged numerical model. It is concluded that, with respect to the numerical solution, more significant are the accuracy of flow field computations and the precision achieved in approximating the bed geometry rather than differences in sediment transport rate formulas. 土木学会 1992-02 eng journal article VoR https://hiroshima.repo.nii.ac.jp/records/2010228 0916-7374 AN10426673 水工学論文集 水工学論文集 36 87 87 92 https://hiroshima.repo.nii.ac.jp/record/2010228/files/suikogaku_36_87.pdf 600.5 KB
