The geological threats that need\nto be considered during an EIA study are as follows:<\/p>\n\n\n\n<ol>\n<li><strong>Compressible Ground and Shrink-Swell Soil<\/strong>: Some soils, such as clay soils, can shrink and swell due to moisture changes, damaging structures built on top of them.<\/li>\n\n\n\n<li><strong>Slope Instability and Landslides<\/strong>: Slope instability can occur due to natural processes such as erosion or due to human activities such as excavation or construction. This can result in <strong>landslides<\/strong><sup><a class=\"text-primary\" href=\"https:\/\/en.wikipedia.org\/wiki\/Landslide\"><strong>[1]<\/strong><\/a><\/sup>, which can cause damage to structures and pose a threat to human life.<\/li>\n\n\n\n<li><strong>Ground Dissolution<\/strong>: The dissolution of soluble rocks such as limestone and gypsum can result in the formation of sinkholes or subsidence, which can cause damage to structures built on top of them.<\/li>\n\n\n\n<li><strong>Liquefaction and Collapse<\/strong>: This can occur in areas with loose or sandy soil during an earthquake or other seismic activity. The soil loses its strength and stiffness, causing it to behave like a liquid, which can lead to the collapse of structures built on top of it.<\/li>\n\n\n\n<li><strong>Fluvial, Coastal, and Groundwater Flooding<\/strong>: Flooding due to rivers, coastal erosion, or rising groundwater can significantly threaten infrastructure and human life.<\/li>\n\n\n\n<li><strong>Aggressive Ground Conditions<\/strong>: This includes areas with high levels of chemical or biological contamination, such as landfills, which can threaten human health and the environment.<\/li>\n\n\n\n<li><strong>Mining Hazards<\/strong>: This includes the potential for mine subsidence, collapse, or water pollution due to mining activities.<\/li>\n<\/ol>\n\n\n\n<h2 class=\"wp-block-heading\"><span class=\"ez-toc-section\" id=\"Importance_of_Geological_Hydro-Geological_Studies_in_EIA\"><\/span>Importance of Geological &amp;

These studies provide valuable subsurface information that can inform decision-making during geohazard-prone project sites&#8217; pre- and post-construction phases. Including hydrological, geotechnical, and geological considerations in the EIA process, preventive measures, appropriate environmental remediation, and protection can be integrated and implemented early on, leading to sustainable use of natural resources. Although incorporating these considerations may come with an additional cost, the repercussions of an environmental disaster resulting from neglecting geological and geotechnical aspects in the EIA could lead to a more severe budget expenditure and environmental problems. Therefore, including geological and hydro-geological studies in the EIA process is necessary to ensure that engineering projects do not adversely impact the environment and that natural resources are used sustainably. Strict compliance with relevant policies and regulations of relevant authorities is also crucial in protecting the environment.<\/p>\n\n\n\n<p class=\"text-left\"><b>Read Our Article<\/b>: <mark style=\"background: #fffd03 !important;\"><a href=\"https:\/\/corpbiz.io\/learning\/relevance-of-baseline-study-in-eia-process\/\">Relevance Of Baseline Study In EIA Process<\/a><\/mark><\/p>\n","protected":false},"excerpt":{"rendered":"<p>Geological &amp; Hydro-geological Studies in EIA play a crucial role as they help to identify and assess potential risks and hazards associated with a proposed project.
