CLIMATE CHANGE AND WATER QUALITY IN URBAN LAKE: ASSESSING IMPACTS OF CLIMATE CHANGE ON WATER QUALITY OF WESTLAKE, HA NOI

Abstract

Some international research using data collected from long-term ecosystem monitoring and indicate that changes in climate change (presipitaion and temperature) can have a significant effect on the quality of surface water in urban lake. Changes in water quality during storms, rain and preriods of elevated air temperature can cause conditions that exceed thresholds of ecosystem tolerance and, thus lead to water quality degradation. These are some warter- quality problems in climate change: eutrophication, oxygen depletion, hygiene, salinization, toxicity, turbidity. Inheritance method and use – similar case method have been used to forecast the effect of climate change on the water quality of West Lake at the end of 21^st century. The result shows that water quality degradations in West Lake will be faced including eutrophication, decrease disolvel oxygen and increase pollution (organic pollution, turbidity, microorganism, pesticide).
