Investigation of groundwater level changes trend (Case study: Lavar plain- Hormozgan)

Investigation of trend of underground water level changes in Lavar plain in Hormozgan province. The purpose of this study is to investigate the quantity of groundwater in the Lavar plain of Fin section in Bandar Abbas region, and identify and assess the consequences of additional extraction of groundwater and provide useful strategies for progressive problems. In order to do this research, 6 observation wells were studied in the period of 20 years (1964-1394). For this purpose all the meteorological, hydrological, hydrogeological, geological and geological data of the area have been collected and analyzed. After that, overdrawing, drainage and drainage losses in the plain groundwater area were calculated. Based on the calculations, the groundwater level of the plain has fallen 28.4 m in the 20-year period, which is an average of 21 centimeters a year on average. Therefore, if no serious and effective action is taken in this area, this plain will face not only environmental degradation but also economic and social problems in the future. To prevent the destruction of the aquifer, which is a vital issue, precise control over the removal of groundwater resources, preventing the development of agricultural landslides, artificial nutrition of groundwater table, promoting culture of conservation and greening of crops is recommended.
