A proposal on arid land sabo works|a case study in Jordan|
Hiroshi IKEYA
Abstract
Arid land is defined by dry]index and precipitation depth (UNEP), and arid land
amounts to the 40% of terrestrial parts of the world. Nowadays sediment]related
disasters by sediment movement such as debris flow, sediment flow and so]on, occur
in arid land. For example, intense rainfall events results in sediment flow that
causes miserable damages to human lives, houses, agricultural land and infrastructure
facilities in Jordan.
>From now, intense rainfall will occur more frequently by climate change, and
development area will be sprawling by increase of population on the dangerous
alluvial fan in arid land of Jordan. Therefore sediment]related disasters will
increase in arid land in future. So it needs the development of the arid land
sabo works that means not only to prevent the sediment]related disasters but also
to use the water of surface flow or flowing water. To make the safety in the arid
land of the world, I propose the arid land sabo works with due regard to the characteristics
of arid land.
Key wordsFclimate change, arid land sabo works, arid land, sediment]related disasters,
