mining directly alter the channel geometry producing a local sediment deficit; floodplain pit mining, commonly close to the active channel, transforms floodplain into an open pit which could capture channel during floods. Beyond these morphological effects the actual in stream mining has to be in line with environmental issues and especially

Miners may straighten channels and stabilize banks with rip rap. Even when successful in keeping pits isolated, the principal biological effects of floodplain and terrace pit mining include Conversion of riparian forest to open pond habitat; Reduced habitat complexity in the channel
PIT AVULSIONS AND PLANFORM CHANGE ON A MINED RIVER FLOODPLAIN TANGIPAHOA RIVER, LOUISIANA Joann Mossa and Steven R. Marks Department of Geography University of Florida Gainesville, Florida 32611 Abstract Floodplain mining creates a vulnerable landscape comprised of pits, bare land and stock piles with minimal vegetation.
Overall, riverine sand and gravel mined from 1970 to 1991 ac counted for 13 21% (one eighth to one fifth) of the state's total production. About half of this was from floodplains of the Yakima River and its tributaries. Physical Effects of Mining with Implications for Salmonid Habitat There are few studies of the effects of floodplain mining.
Environmental impact of a major copper mine spill on a river and floodplain system. Author links open overlay panel however, research into the environmental effects of mining on remote rangeland agricultural catchments, is notably absent. is a Cu heap leaching operation involving open pit mining of the Cu oxide deposits with all
Surface mining, including strip mining, open pit mining and mountaintop removal mining, is a broad category of mining in which soil and rock overlying the mineral deposit (the overburden) are removed, in contrast to underground mining, in which the overlying rock is left in place, and the mineral is removed through shafts or tunnels.

Environmental problems of placer gold mining in the Zaamar Goldfield, Mongolia meandering river channel, and adjacent floodplain, river terrace, and alluvial fan grassland ecosystems. Damage results from both open pit extraction of gold bearing sand and gravel Possible effects of siltation of the Tuul river include 1. destruction of
mining; and floodplain and terrace pit mining. means that potential adverse effects need to be carefully assessed and managed in these environments. extractive operation; Extraction from rivers and marine areas re suspends fine sediment, which can cause
The former off channel pit is then converted into an in channel pit, and the effects typical of instream mining can be expected. Another important concern of floodplain mining is that wet pits typically intersect the water table, and therefore constitute a preferential path of ground
wildlife habitat. See the Mining and Reclamation Plan (2007) for the floodplain construction and planting plan specifics. Granite also proposes to develop a terrace pit mine within the project area. The proposed mine footprint will cover approximately 30.3 acres and be developed in three phases (See Exhibits 6a

Interaction of Ground Water and Surface Water in Different Landscapes Ground water is present in virtually all landscapes. The interaction of ground water with surface water depends on the physiographic and climatic setting of the landscape. For example, a stream in a wet climate might receive ground water
