摘要

利用数值模拟和悬浮颗粒物(SPM)浓度图，研究了2020年3月3日阿迪格-加尔达泄洪道开通对加尔达湖的影响。SPM地图由使用BOMBER生物光学模型处理的Sentinel-2图像获得。研究了三张卫星图像:28/02/2020,04/03/2020和07/03/2020。地图显示SPM浓度显著增加，特别是在靠近水力隧道出口的湖泊北部。计算结果与模拟流场一致。遥感有效地捕捉到事件的空间和时间变化，而数值模拟解释并证实了观测到的模式。通讯作者:ghirardi.n@irea.cnr.it

Using remote sensing and numerical modelling to quantify a turbidity discharge event in Lake Garda

We investigate the effect of the Adige-Garda spillway opening on the 03/03/2020 on Lake Garda using numerical modelling and maps of Suspended Particulate Matter (SPM) concentration. SPM maps are obtained from Sentinel-2 images processed using the BOMBER bio-optical model. Three satellite images are examined: 28/02/2020, 04/03/2020 and 07/03/2020. Maps indicate a significant increase in SPM concentrations, especially in the northern part of the lake close to the hydraulic tunnel outlet. Results are consistent with the modelled flow field. Remote sensing effectively captures the event’s spatial and temporal variation, while numerical modelling explains and corroborates the observed patterns.

期刊介绍： The Journal of Limnology publishes peer-reviewed original papers, review papers and notes about all aspects of limnology. The scope of the Journal of Limnology comprises the ecology, biology, microbiology, physics, and chemistry of freshwaters, including the impact of human activities, management and conservation. Coverage includes molecular-, organism-, community-, and ecosystem-level studies on both applied and theoretical issues. Proceedings of workshops, specialized symposia, conferences, may also be accepted for publication.
