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 and 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 and 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.
