Abstract
XangThoi’s Lake and canal system in urban of CanTho city is an important interface between recreational purpose and ecology, which demands environmentally responsive strategies, urban flooding control and water quality. The study attempts to investigate the water quality and hydrological interventions. Water quality assessment of the lake and interlinked canals was carried out. A total of 12 points and samples were collected and observed during post-monsoon, pre-monsoon and were subjected to physical, chemical and bacteriological analysis. Besides the domestic and international standards were applied to evaluate the degree of pollution, the spatial and temporal variability of surface water pollution were conducted by the estimated water quality index. It was concluded that experimental plans like linking of lake and canals have considerable impacts on the water quality on lake and disrupt the balance of not only lake ecosystems but also polluted receiving waters. The specific hydrological impact assessment and cumulative impact assessment framework should be explored with respect to local context.
