Abstract
Debris flows often cause substantial losses to human life and the economy.
Damage can be effectively reduced using numerical simulation models, which
can describe the debris flow process and determine possible effects of sabo
dams, or erosion and sediment control dams. However, non-experts find it very
difficult to run simulations independently, because the systems do not currently
have an efficient user interface. We developed a system that produces one- and
two-dimensional debris flow simulations and is equipped with a graphical user
interface (GUI). The system is based on an integration model and employs onedimensional
simulations for gully areas and two-dimensional simulations for
alluvial fan areas, and then considers their mutual influence in boundary areas
between gullies and alluvial fans. The system was developed with \“MS Visual
Basic.NET.” Data can be input using a mouse and be checked on the monitor,
users can see real-time visualized images of the debris flow during the
simulation. The interface enables non-expert users to run the debris-flow
simulation independently, enabling better solutions for sabo engineering.
Keywords: debris flow, graphical user interface (GUI), numerical simulation,
one- and two-dimensional integration model.
1 Introduction
Debris flows can cause severe damage in gullies and alluvial fans and Sabo
works is to reduce and prevent sediment disaster such as debris flows. Sabo
dams, or erosion and sediment control dams, effectively prevent and reduce
disasters caused by debris flow, and many sabo dams have been constructed in
Japan. These dams can reduce the energy of a debris flow, thereby controlling
