In order to improve present and future management of the sediment resource, it is important to gain a better knowledge of the geomorphic effects of sediment mining and to extend documented cases of the types and amount of miningrelated channel adjustments to a .
Fisheries biologists often find themselves involved in the complex environmental and regulatory issues related to instream sand and gravel mining. This paper provides an overview of information presented in a symposium held at the 1997 midyear meeting of the Southern Division of the American Fisheries Society in San Antonio, Texas, to discuss environmental issues and .
The issue ofinstream gravel mining has many dimensions. In a growing economy, the availability of construction materials can be a limiting factor of growth and the economic benefits of gravel production must be weighed against the environmental costs. At the present time, quarry rock is used in much greater quantities than instream gravel in most counties in .

Floodplain gravel pits have the potential to become wildlife habitat upon reclamation, but may be captured by the active channel and thereby become instream pits. Management of sand and gravel in rivers must be done on a regional basis, restoring the continuity of sediment transport where possible and encouraging alternatives to riverderived aggregate .
· Abstract Mining of gravel for construction aggregate in California is regulated under the concept of 'reclamation', borrowed from open‐pit coal mines, which are recontoured and returned to productive use (such as agriculture) after mine closure. The concept works for dry terrace pits and can be adapted to creation of wildlife habitat in wet terrace pits.
In this paper, a methodology is pre sented to couple a sediment transport and morphological simulation model with a management model based on genetic algorithm optimization, to search for good gravel mining practices, determining ade .

Mining operators, in conjunction with cognizant resource agencies, must work to ensure that sand mining is conducted in a responsible manner. Excessive instream sandandgravel mining causes the degradation of rivers. Instream mining lowers the .
Geomorphic Effect Of Instream Gravel Mining Case Study (Dehbala River Kerman) Author(s): ... In this study, we have investigated the effects of gravel mining on river morphology in Dehbala River of Kerman. First, basic researches including physiographic, geological, meteorological, erosion and sediment studies were conducted, then morphology of Dehbala River was studied .
· Abstract We used an informationtheoretic approach to examine the variation in detection probabilities for 87 Piedmont and Coastal Plain fishes in relation to instream gravel mining in four Alabama streams of the Mobile River drainage. Biotic and abiotic variables were also included in candidate models.
· gravel replenishment or recruitment has been used as a technique to mitigate the reduction of sediment load below dams (kondolf 1997), but has not been considered to be a viable option for instream mining sites because of the difficulty in distributing the aggregate naturally and completely throughout the basin prior to the next high water event .
· Instream gravel mining includes various excavation methods within a stream's boundaries as well as pits loed within the meander belt on floodplains. Instream mining and stream restoration are often perceived to be mutually exclusive; however, careful planning, design, and implementation of a reclamation plan can allow restoration activities to occur .
