Alemu Belay: Water hyacinth; Evapotranspiration; Water quality; Lake Tana My research and academic interests focus on the interaction between aquatic invasive plants, hydrological processes, and water quality in freshwater ecosystems. In particular, my study examines the impact of Water hyacinth on evapotranspiration and water quality in Lake Tana. The research aims to quantify water losses caused by dense water hyacinth infestations and assess their effects on key water quality parameters. This work contributes to a better understanding of how invasive species influence water resource availability and ecosystem health, and supports the development of effective management strategies for sustainable water resources in Ethiopia and similar environments.
