Research on Klang river basin shows how growing urban populations contribute to rubbish buildup in drainage systems, reducing capacity to handle downpours, says expert
PETALING JAYA: Population growth and increasing rubbish accumulation in Klang Valley drainage systems are closely linked, placing additional pressure on existing infrastructure and raising the risk of recurring flash floods, said Universiti Teknologi Malaysia (UTM) civil engineering associate professor Dr Nor Eliza Alias.
She said doctoral research on the Klang River basin showed how growing urban populations could contribute to the accumulation of waste in drainage systems, further reducing their capacity to handle heavy rainfall.
