Physical water quality and algal density for remediation of algal blooms in tropical shallow eutrophic reservoir

Abstract

This study is on physical water quality data with regards to algal bloom occurrence in a shallow eutrophic reservoir in Malaysia. Some of the important physical parameters emphasized for future remedial studies for the Semberong Dam, a tropical reservoir, are dissolved oxygen, temperature and light intensity. The use of Planktothrix culture as a dominant algae or a mixed culture with a spike of this dominant algae is suggested for remedial study. Other in?uencing factors for consideration are food-web interaction such as in?uence of macrophytes; metereological mainly climatic features, wind-?ows and rainfall; as well as hydrological factors such as water in?ows, lake size and depth, catchment area apart from human and agricultural activities effecting algal bloom formation.
