Description
Summary:This study examined the spatiotemporal dynamics of water hyacinth and its impact on Lake Tana's water quality using Sentinel-2 and MODIS Terra satellite imagery. A Random Forest algorithm was used to map water hyacinth distribution. High water hyacinth population was observed in the northeast sector of the lake. From 2015 to 2023, water hyacinth area coverage increased by 1.67 km 2 annually. Areal mean water hyacinth biomass also increased (2016-2022). The areal mean surface temperature decreased significantly in all seasons except winter from 2001 to 2022 (P
