What Are The Negative Effects Of Sand Mining?
The ill effects of sand mining on wildlife are not confined to beaches and sandbanks, but also include underwater ecosystems When sand is mined from seabeds or river beds, it can create create turbidity in the water The effect of mining is compounded by the effect of sea level rise Any volume of sand exported from streambeds and coastal areas is a loss to the system Excessive instream sand mining is a threat to bridges, river banks and nearby structures Sand mining also affects the adjoining groundwater system and the uses that local people make of the riverImpacts of Sand Mining ismenvisnic Presence of sand mining has significant effects on morphological characteristics such as channel bed degradation, erosion of river bank and change in the plan form of a river ( Collins and Dunne, 1990, Sear and Archer, 1998 )Impact of sand mining on alluvial channel flow

Environmental Effects of Sand and Gravel Mining on Land
Although sand mining contributes to the construction of buildings and development, its negative effects include the permanent loss of sand in areas, as well as major habitat destruction Sand mining is regulated by law in many places, but is still often done illegallySand mining activities are one of many recognized pressures affecting riverineecosystems, where biodiversityisalready in rapiddecline(World Wildlife Fund, 2018) Increasingly, there are media reports about the negative environmental and social impacts of sand mining, and as calls grow for stronger regulation of mining (Schandl et al, 2016), there is aImpacts of riverine sand mining on freshwater ecosystems Impacts of sand mining and gravel extraction can be classified into three categories as presented by Stebbins (2006) There are physical impacts which are a result of mining from streambed causing alteration of channel slope and changes in channel morphologyCASE STUDIES OF ENVIRONMENTAL IMPACTS OF SAND

Assessment of the Impact of Sand Mining on Bottom
Sand mining, among the many activities that have significant effects on the bed changes of rivers, has increased in many parts of the world in recent decades Numerical modeling plays a vital role in simulation in the long term; however, computational time remains a challenge In this paper, we propose a sand mining component integrated into the bedload continuity equation and combine it with Increasingly, there are media reports about the negative environmental and social impacts of sand mining, and as calls grow for stronger regulation of mining (Schandl et al, 2016), there is a need to understand the scientific evidence of mining impacts to underpin management Impacts of sand mining on rivers may be direct or indirect (Figure 1 Impacts of riverine sand mining on freshwater The purpose of this study is to examine the impact of sand mining activities to environmental conditions of the Komering river Field studies have been conducted during the period of AprilJune 2016 for observing the condition of the river channel, water quality measurement and mining activitiesImpact of sand mining activities on the environmental
