IAHR, founded in 1935, is a worldwide independent member-based organisation of engineers and water specialists working in fields related to the hydro-environmental sciences and their practical application. Activities range from river and maritime hydraulics to water resources development and eco-hydraulics, through to ice engineering, hydroinformatics, and hydraulic machinery.

Development of ‘kanako,’ a wide use debris flow simulator equipped with gui

Sabo dams are effective at preventing and reducing disasters caused by the flow of debris, and many such dams have been constructed in Japan. Researchers have recently proposed a variety of numerical simulation models to examine the effects of sabo dams, and some of these have been put to practical use in planning sabo dam arrangement. However, no efficient user interface has been developed, so these systems require special training. It is very difficult for a beginner to prepare the many datasets and to select parameters, so engineers in flood management offices are unable to conduct simulations independently, and require specialists. As the models are further developed, the knowledge gap between engineers and specialists appears to be gradually increasing. In this study, we developed a one-dimensional debris flow simulator equipped with a graphical user interface (GUI) that can model the effects of closed, slit, and grid types of sabo dams. The system was developed with MS Visual Basic.NET and is compatible with Windows. Its GUI is interactive and is easy for beginners to master. The numerical simulation model reproduces variations in a mountainous riverbed caused by debris flow. This model incorporates two grain size classes for sediment material and uses one-dimensional governing equations for a stony debris flow. Users can input datasets for simulations using a mouse; these appear on the monitor and during simulations, users can view real-time visualized longitudinal images of debris flows, sediment graphs, and hydrographs. The GUI allows users to find better solutions effectively and permits them to run a debris-flow simulation independently.
