Assessing intermittent saline inflows in urban water systems [PDF]

Water Science and Technology, 2021
Abstract Urban water drainage systems' primary function is to transport sanitary or stormwater. The intrusion of saline waters has recognized detrimental effects. Especially in coastal areas, saline inflows can compromise performance by increasing the risk of untreated discharges, weakening the structural condition of concrete or ...
