| Outline of Final Research Achievements |
This study addressed the change of endorheic inland lakes. The hydrological analysis was conducted for "a cause of the change," and field surveys and observations were for "environmental impacts resulting from the change."
In the terrestrial water circulation model, we performed a water circulation analysis considering climate change and human activities in the whole basin. The model could show that the water level of Lake Turkana was displaced to different levels before and after the low rainfall period around the year 2000. In addition to surveying the damage caused by the water level change in the surrounding area, meteorological observations and in situ measurements of soil moisture were conducted. Satellite monitoring of actual irrigated areas was also conducted, and the impacted area by severe drought in 2001 was accurately detected in the Aral Sea basin.
