Nov 22, 2019 Sand is relatively common, mined in every state, and typically locally sourced due to high transportation costs, so deposits should be near populated areas where sand and gravel is in demand. Deposits should also be close to the ground surface, which makes sand and gravel easy and cheap to extract with open-pit mines or dredging.
Each mixture used the same gravel, and sand was added to produce mixtures containing 6, 15, 21, 27, and 34 % sand. Control of other variables allows us to isolate the effect of bed sand content on transport. As sand content increases, gravel transport rates increase by orders of magnitude, even though the proportion of gravel in the bed decreases.
K gu that supply sand and gravel to Lome and its surroundings are critical evaluated. However, this research reveals the vast inequalities and social injustices that lie behind this lucrative activity of sand gravel quarrying. Key words: Sand and gravel, transporters, miners, environment, socio-economics. INTRODUCTION

Field transport experiments were conducted in an oxic sand and gravel aquifer using Br (bromide ion), Cr (chromium, injected as Cr(VI)), Se (selenium, injected as Se(VI)), and other tracers. The aquifer has mildly acidic pH values and low concentrations of dissolved salts. Within analytical errors, all mobile Cr was present as Cr(VI). All mobile Se was probably present as Se(VI).
