The research has been carried out to assess the rate of desertification of the karst ecosystem regarding land damage in the Darul Imarah, Aceh Besar District. This study aims to determine the level of damage to the karst ecosystem and its effect on water quality and to determine the condition of land cover in the Mata Ie karst ecosystem., Aceh Besar District. The data collection method used is using Landsat 8 satellite imagery to assess the level of damage to the karst ecosystem area. The assessment of water quality and quantity was carried out by means of a direct survey in the Mata Ie karts

This study includes a general description of the Earth’s karst types based on literary data and field observations. An improved classification of karst types distinguishes the main group, group, and subgroup; and, a division of karst types involves a main karst type, karst type, subtype, variety, and non-individual karst type. The relation between karst type and karst area is described. The role of various characteristics of karsts in the development of primary, secondary, and tertiary karst types is analyzed. Their structure is studied, which includes a geomorphic agent, process, feature, fea

Karst caves are among the most common and critical geological hazards in karst regions. Due to their marked differences in physical properties compared to the surrounding rock, they can be detected using various geophysical techniques. Karsts have developed on the surface of the Qingshuitang Wollastonite Mining Area in Huangtian Town, Hezhou City, Guangxi Province. In line with mine safety production requirements, a professional assessment of the potential development of karst caves must be conducted within 150 m of the mining area's surface.

The Tazhong area of the Tarim Basin contains abundant oil and gas resources in Ordovician carbonate rocks, especially in the karst pores and caves of the Yingshan Formation. Research has indicated that the Yingshan Formation underwent a 7–11 Ma exposure during the middle Caledonian Period, resulting in large-scale karst pores and caves. However, the continental freshwater karst model cannot adequately explain the origin and distribution of karst pores and caves. In order to develop a more accurate karst model to guide petroleum exploration in the region, we analyzed the karst morphology, cave

Abstract:
Karst topography is the result of a specific combination of geological conditions, precipitation, biota, and temperature, and is characterized by the gradual solution of the underlying bedrock and the development of underground drainage routes for surficial runoff. Many of these karst landscapes are found in urbanized areas, where the potential for anthropogenic impact is quite high. In many instances, municipalities on karst terrains choose to mitigate these impacts by implementing ordinances that place restrictions on permissible land uses near karst landforms.

Abstract:
A hydrostratigraphic framework has been developed for southern Ontario consisting of 15 hydrostratigraphic units and 3 regional hydrochemical regimes. Using this framework, the 54 layer 3-D lithostratigraphic model has been converted into a 15 layer 3-D hydrostratigraphic model. Layers are expressed as either aquifer or aquitard based principally on hydrogeologic characteristics, in particular the permeability and the occurrence/absence of groundwater when intersected by a water well or petroleum well. Hydrostratigraphic aquifer units are sub-divided into up to three distinct hydrochemical reg
