Modeling the hydrological impacts of land use/land cover changes in the Andassa watershed, Blue Nile Basin, Ethiopia

模拟土地利用/土地覆盖变化对Andassa流域、蓝色尼罗河盆地、埃塞俄比亚的水文影响

Highlights:

There were expansions of cultivated land and built-up area, and withdrawing of forest, shrubland and grassland during the 1985–2015 periods, which are expected to continue in the 2030 and 2045 periods.

· The LULC changes, which had occurred during the period of 1985 to 2015, had increased the annual and wet season flow, surface runoff and water yield while the dry season flow, lateral flow, groundwater flow and ET were reduced.

· The 2030 and 2045 LULC states are expected to affect the hydrological components with the same direction.

亮点:

在1985至2015年期间,种植地和建筑用地不断扩展,森林、灌木地、草地不断回收,这有可能一直持续到2030和2045年。

在1985年至2015年期间发生的土地利用和土地覆盖的变化,增加了全年和雨季的径流、地表径流和水量,然而旱季径流、侧向流、地下水和ET却降低了。
