Abstract
A Groundwater resource is one of the most important sources that provide agriculture, domestic and industrial demand. The aim of this study is trend analysis of quantity – quantity groundwater fluctuations in the Minab plain from Hormozgan province. In order to assessment quantity and quality fluctuations was used Groundwater Resource Index (GRI) in the time period 1968- 2015 and EC, pH, SAR, TH in the time period 2008-2015, respectively. IDW method was used to map zoning of quality characteristics in ArcMap software. Mann- Kendal trend test used to analyze groundwater level oscillation. Result showed that groundwater level have decreasingly trend in the seasonal and annual time scale. As, Mann- Kendal Statistic is strong in the East and Southern plain. Iso- hyetal groundwater quality map showed that much of area (0.63%) has suitable water quality and the central of plain (0.37%) has unsuitable water quality.
