1. Introduction. Heavy minerals with densities higher than 2.89 g/cm 3 are generally considered minor components of sand or sandstones, typically forming 1 percent of the weight in the samples (Mange and Wright, 2007).Heavy-mineral analysis is an effective tool for studying the sedimentary provenance of siliciclastic rocks, …

The continuous progress in machine learning, and its implementation has intensified competition among scientists for building more efficient and accurate predictive models to prevail the complicated, non-stationarity, and dynamism behavior of the sediment transport in rivers. It should be noted that machine learning techniques are data-driven ...
The widening of river bank due to sand mining is analysed by comparing the area represented in the SOI Top sheets (1969) and Google Earth Imagery (2008) with the field maps prepared. IV. Sand Mining in the Neyyar River Basin River sand is mined extensively from the lower course of the Neyyar River, stretching for about 30 KM
River sand mining does not alter the chemical properties of the sand but it does alter the local and downstream water quality. The extraction of sand from wet …
