| Serious flood damages occurs every year in Japan. Many regions
have been designated as hazardous areas because of the regularity of damages
from water. Rock slides often accompany heavy rains in these regions and seriously
impact roads and railroad infrastructure. |
| Many private homes and factories are build at the foot of mountains and
on the edges of river bank. Because of these population densities in regions
vulnerable to flood damage, new methods are required to prevent the escalating
costs of these disasters. |
| Currently the most common form of soil stabilization in these areas is to
build earthen barriers or to lay down soil over concrete blocks. In most cases
of serious flooding, however, these measures have been not been able to stop
the river. |

| Plasma torch soil remediation could change this. Because it makes the underlying
soils many times stronger than concrete, it would be able to prevent the banks
from washouts caused by the wild water, similar to piling the banks with vitrified
columns. The explanation of this effect is shown in Figure 1. |
| Rivers without flooding would be able to maintain their ecological balance
and beauty. |
