Hydrology of acidic mine pit lake: a case study of excopper mine Pit Lake, Mamut, Sabah Malaysia

Hydrological study of pit lake was carried out in ex-Mamut Copper Mine (MCM), Ranau Sabah. Gauging stations were established to measure surface inflows and outflows of the pit lake. Each station was equipped with a continuous water level recorder to record water level data at 10 ̶ minutes intervals....
