Effect of Sinkholes on Groundwater Resources in Arid and Semi-Arid Karst Area in Abarkooh, Iran

Abstract

Despite protection measurements and their natural position, groundwater resources are very vulnerable due to natural and anthropogenic impacts. This is especially emphasized in karst arid and semi-arid zones, due to increased requirements for water. Paper deals with the impacts of the sinkholes on groundwater quality on Abarkooh city in Iran. There are 28 sinkholes located in Abarkooh plain. The aims of the paper are to specify the characteristics and causes of sinkholes occurrence, as well as to specify the vulnerable areas and future development of sinkholes and their effect on the groundwater resources. Next step is defining of the original procedure for protection of groundwater resources in characteristic areas, as karst arid and semi-arid areas are. By taking into the account geological, hydrogeological and meteorological data, and finally through hydrogeochemical and geophysical analysis, final conclusions and recommendations for the protection of the groundwater resources are obtained. This has significant importance for water supply of the Abarkooh city in Iran. It should be noted that the mentioned methodology for the protection of groundwater resources could be applied in other arid and semi-arid areas.

Response of vegetation normalized different vegetation index to different meteorological disaster indexes in karst region of Guangxi, China

“…In the past 50 years, the climate in southwest of China tended to be “warm and dry” on the whole [ 22 ], and the change of surface water and thermal environment has brought a new challenge to control rocky desertification in karst areas, so the exploration of the effects of changes in climate factors on vegetation in karst areas has gradually become a hot issue. Existing studies have shown that drought stress has become an important factor affecting plant survival in a region [ 23 , 24 ], and it is also the main reference for species selection in rocky desertification areas [ 25 ]. Some scholars have found that karst The surface vegetation is significantly correlated with both temperature and precipitation [ 26 ], and the stress effect of temperature is stronger than that of precipitation [ 27 ].…”
