最近的极端水文事件,比如高降雨量和暴风雨,由于其相对罕见的趋势,与全球气候变化有关,它们通常被描述为具有不同的频率和更高的强度。在2018-2019年季节期间,西北阿拉伯湾也观察到了类似的极端降雨趋势。暴雨事件引发了阿拉伯沙特河的高流量,where,在这些事件之前,在过去40年中,排放率呈下降趋势。ShattAl-Arab提供各种物理,化学,和该地区的生物学功能。在这项研究中,记录了阿拉伯湾西北部一些近期和广泛的盐度测量和叶绿素a后处理卫星图像,以评估该地区对较高排放的响应。结果表明,在降雨事件期间和之后,盐度显着下降,以响应阿拉伯沙特的较高排放。更高的排放影响延伸到科威特的大部分海岸线,包括科威特湾。极端事件后叶绿素a的分布增加了一倍,强调阿拉伯沙特的影响。总的来说,结果表明,极端事件期间阿拉伯沙特的排放量超过1400立方米/秒,while,在以前的季节里,它很少超过80m3/s。由于水环境过程的突然和反向转变,较高的排放水平将导致多层次的生态变化。
Recent extreme hydrological events, such as high rainfall and storms, have been linked to climate change worldwide due to their relatively uncommon trends, which are generally described as having varying frequencies and higher intensities. Similar extreme rainfall trends were observed in the northwest Arabian Gulf during the 2018-2019 season. Heavy rainfall events have triggered high discharges in the river of Shatt Al-Arab, where, prior to these events, the discharge rate has exhibited a declining trend over the past 40 years. Shatt Al-Arab provides various physical, chemical, and biological functions in the region. In this study, some recent and extensive measurements of salinity and post-processed satellite images of chlorophyll-a in the northwest Arabian Gulf were recorded to assess the response of the region to the higher discharges. The results indicated that the salinity decreased significantly during and after the rainfall events in response to the higher discharges from Shatt Al-Arab. The effects of higher discharges extended over most of Kuwait\'s coastline, including Kuwait Bay. The chlorophyll-a distributions doubled after the extreme events, emphasising the effects of Shatt Al-Arab. Collectively, the results indicated that the discharge from Shatt Al-Arab during the extreme event exceeded 1400 m3/s, while, in the previous seasons, it rarely exceeded 80 m3/s. The higher discharge levels of discharge would result in various changes in ecology at multiple levels due to the sudden and reversing shift in the hydro-environmental processes.
