### Mflow_02

#### What is Mflow_02?

Mflow_02 is an analysis solver to calculate two-dimensional plane unsteady flow and riverbed variation by unstructured meshes of finite element method in orthogonal coordinate system (Cartesian coordinate system). The original version of Mflow_02 was based on programdeveloped in late 1980s by G. Tomitokoro of Shinshu University. Thereafter, M. Gamou (former staff of Pacific Consultants Co. Ltd, current Gamou Intelligent Technology Co. Ltd. (G.I.T.)), K. Hamaguchi and M. Ichiyama(Pacific Consultants Co. Ltd) led the core work to expand and develop the model, firstly added some functions like moving boundary model and riverbed variation calculation, etc.. It has been registered as a calculation solver for iRIC Version2.3 in (July) 2014.

By applying the characteristic of unstructionedl meshes, this model can calculate unsteady flow in the area including structures like pier, weir, etc., or to calculate flooding of complicated area, like floodplain area and the river channel network with many distributaries and confluences,. In addition, it’s possible to reproduce the calculation of riverbed variation and the appearance, development and movement of sandbar. There are a number of practical applications, like the application for impact assessment of piers, etc., impact assessment of vegetation and trees, flooding calculation and estuary sandbar flush.
