1-dimensional solver for flow and morphology in rivers with general shaped cross-section
Nays1D+ is a one-dimensional solver for rivers with general cross-sectional shape. This solver can calculate flows by non-uniform steady flow model as well as unsteady flow model. The solver also calculate bed deformation considering bedload. The obstacles such as bridge pier and spur-dikes, inflow from tributaries can be also considered in the computaions. You can visualize the results using two-dimensional visualization window equiped in iRIC with the methods of color contour, vectors, particl trace, ets.
