and and gravel extraction is the most common form of mining in the state. Because sand and gravel is relatively inexpensive to mine but expensive to transport, most operations are located close to where the resource will be used. As a result, gravel pits have been developed in every county.
As a result of gravel mining, the zero elevation contour line has moved inland (indicated as 0.01 m for hydrologic consistency, Fig. 5), and it is now located about 1.5 km upstream from St. Pere Pescador in winter, and 2 km in summer. In consequence, approximately half of the river course along the alluvial plain shows an almost zero gradient.

The goal is to reduce the amount of sediment and turbidity in streams and rivers in Louisiana that result from sand and gravel mining and improve water quality in watersheds where these mining operations exist. Aggregate production accounts for about half of the non fuel mining
A federal court jury on Tuesday awarded more than $100 million in damages to two gravel mining families that accused Sacramento County government officials of putting them out of business for the
Keeping mining equipment out of this area assures that the stream will not change its course as a result of the mining. It will also prevent eroded material from causing siltation problems downstream and will protect the roots of plants that prevent bank erosion. When gravel mining, never relocate or straighten stream channels.

In Kyser, the township responded to feuds over gravel mining by adopting a zoning ordinance that demarcated a gravel district. Mining and extraction were only permissible within the district. The plaintiff owned agriculturally zoned property that abutted the gravel district.
Sand and gravel are used for road construction, for mixing with asphalt, as construction fill, and in the production of construction materials like concrete blocks, bricks, and pipes. It is also used to make roofing shingles, used on icy roads in the winter, for railroad ballast, and water filtration.
gravel removal disrupts sediment supply and channel form that can result in a deepening of the channel over great distances upstream and downstream of the mine site as well as sedimentation of habitats downstream. There are presently three primary methods for mining sand and gravel in Missouri Bar skimming, in stream (bucket loader).

effects from sand and gravel mining operations upon ground water quality. Sand and gravel operations do have the potential to adversely impact ground water quality, both as a result of the extraction process and in site reclamation. However, sand and gravel mining is also an important economic resource as well as a necessary resource
Instream gravel mining can disrupt the preexisting balance between sediment supply and transporting capacity and can result in channel incision and bed degradation Instream gravel extraction can increase suspended sediment, sediment transport, water turbidity, and gravel siltation
In addition, North Dakota provides for the removal of minerals such as stone, gravel, and clay, found during surface coal mining operations. In order to mine such minerals, the mining company must demonstrate that such removal is lawful and will protect the environment and public health and safety and will achieve reclamation consistent with
