Water quality characteristics and profiles in a developing urban catchment / Hasnaliza Aini Abd Talib

Increasing development and urbanization have made urban runoff a major problem both from the perspective of the flow quantities and qualities. The quantities and qualities of urban runoff depend on catchment characteristics. In Malaysia, urban drainage systems are designed to convey excess water to...
