Assessment of natural sand and pond ash in Indian context
free download

Energy generation through thermal power plants is very typical now days. Pond ash (PA) from these thermal plants is available in large quantities. Pond ash utilization helps to reduce the consumption of natural resources. In current time natural sand are using and a it is costly

Current Issues and strategies of hydropower generation in the multi- sand river A case study for the upstream of Wu-jie dam
free download

The narrow river channel made the channel soil sand transport blocked, resulting in easy siltation at tail water outlet. The collapsing of the sand on the other side of the bank collapses into the river, which endanger the discharge of power generation tail water
