Offshore sand and gravel extraction involves the abstraction of sediments from a bed which is always covered with seawater. This activity started in the early twentieth century (in the mid1920s, in the UK), but did not reach a significant scale until the 1960s and 1970s, when markets for marine sand and gravel expanded and dredging technology improved (Figure 1).
Vegetation succession on the Lorraine CCBE results in an improvement in soil conditions, leading to the installation of deeprooted species, which could represent a risk to CCBE longterm performance. Hence, the characterization of vegetation succession is an important aspect of
Keywords: Assessment, Impacts, Gravel mining, Sand mining, Environment. 1. Introduction Sand and gravel mining refers to the actual process of removal of sand or gravel from a place of their occurrence (Langer, 2003). The places of sand and gravel occurrence are oceans, rivers, streams, flood plains or hills and mountains.
#0183;#32;The effects of gravel mining can be detected clearly in the DoD maps (Figs. 7A and 8A). The spatial extent of erosion/excavation corresponds very well with the outline of the former mining activities. Even though the DoD covers a longer period of time, the changes are still remarkable.
Placer mining. Placer mining is a way of obtaining mineral and metal resources from loose river sediments. The water helps sift the valuable resources (such as gemstones or gold) from the sand, mud, and gravel in the riverbed. Placer mining occurs on a much smaller scale than other methods of surface mining.

Gravel Mining Operations. Gravel mining operations on Wynoochee River being excavated by dragline, Courtesy: Kondolf, 1994. Operations include the wet excavation of riverbeds for gravels and the dry pumped excavation of floodplains. The advantage in the later method is the ease of excavation, whereas the pumping comes at a cost as well.
#0183;#32;Mining is an inherently destructive industry, and the mining effects of even a single operation can have a severe impact on the environment and the wildlife that lives nearby. Although there are some regulations in place that are intended to minimize the damage, they are not enough to allow mining and wildlife to exist in harmony, especially in cases where the regulations are difficult to enforce.
