uncontrolled mining activities such as sand excavation from rivers and the destruction of riverine habitat for solar salt production (DHI and Samaki 2014). This can result in increased sediment and silt load in rivers, causing coastal accretion and in places the smothering of habitats such as coral reefs UNEP/ Nairobi Convention Secretariat (2009).
Limestone channel lining was placed directly into four severely impacted tributaries of Rock Creek, treating the AMD before it enters Rock Creek. A landslide was stabilized and revegetated and an onbench acidic pond was eliminated. Dosing of the tributaries with sandsized limestone particles was reduced as the reclamation in the tributaries was

May 30, 2018· In general, exploitation of rock materials, such as limestone or granite exploitation, can cause serious damage to the environment near a mine area. With economic development and the everincreasing demand for ore resources, mining activities have induced very .
runoff after heavy rainfall often increases the sediment load of nearby water bodies. In addition, mining may modify stream morphology by disrupting a channel, diverting stream flows, and changing the slope or bank stability of a stream channel. These disturbances can significantly change the characteristics of stream sediments, reducing
