Mining activity always presents threats to soil and water pollution. As an extractive industry, it disturbs the ground biodiversity associated with plants. Its operations have led severe geological environmental problems, including depletion of land resources, dangers, ecological landscape devastation that may accelerated desertification mining areas. This case study analyzed soil’s physical ch...

We study the evolution of a one-dimensional pile, empty at rst, which receives a grain in its rst stack at each iteration. The nal position of grains is singular: grains are sorted according to their parity. They are sorted on trapezoidal areas alternating on both sides of a diagonal line of slope p 2. This is explained and proved by means of a local study. Each generated pile, encoded in heigh...

Abstract In Indonesia, sea sand mining was introduced in the late 1970s, and one of sites is Banten Province, Indonesia. Sea waters began 2003 after issuance a permit by Regent Serang Regency, namely Decree No. 540/Kep.68/Huk/2003, which updated Regional Regulation Regency 2 2013 on Zoning Plan for Coastal Small Island Areas 2013-2033. Studies related to marine Banten, Indonesia are required ac...

Abstract— In recent days the demand for river sand is increasing due to its lesser availability. Hence the practice of replacing river sand with M-Sand is taking a tremendous growth. It is also inferred from the literature that replacement of normal sand with M-Sand produces no appreciable increase in compressive strength due to the variation in the pore size of concrete at micro level. This pa...

Sediment deprivation from dam installments contributes to beach erosion yet the underlying physical and economic factors linking them together have traditionally been isolated during regional planning. In order to gain a better understanding of the behavior of a managed beach system, a dynamic simulation model was developed incorporating physical and monetary factors influencing the amount of a...
