Fluvial Recharge of Sand Mining Pit

Fluvial Recharge of Sand Mining Pit. Accuracy in modeling fluvial processes becomes increasingly important as development occurs along waterways. The FLUVIAL-12 (1, 2) model is used to simulate the recharge of sand mining pits in the San Luis Rey River during a large storm. This study shows how the FLUVIAL-12 model produces a non-uniform deposition of sediment both in cross-sectional profile ...

Flow past a sand mining pit - CORE

The numerical model is used to study the evolution of a hypothetical channel bed. Effects of flow characteristics, pit characteristics and sediment characteristics on bed evolution due to sand mining are studied. It is found that the sediment carrying capacity of water increases with discharge but this relationship is not linear.
