The Evaluation of Soil and Water Resources Sustainability and Assessment of their Qualitative and Quantitative Changes by the Use of GIS and Geostatistics

Abstract:
Nowadays, the rapid growth of population causes excessive exploitation and also utilization beyond the natural resources capacity and leads to soil and water resources degradation, As a result, knowledge of soil and water resources is important. The main purpose of this research is quantitative and qualitative study of water resources in Kerman plain and also evaluation of soil quality changes in this plain. After collecting the data relating to water level, geological map of study area, and also qualitative indices of soil and water including electrical conductivity (EC), water acidity (pH), etc, interpolation and the map of each factor was provided by the use of GIS. The results showed that groundwater quality has been suitable in the southeast of the study area because of the groundwater recharge by the rivers. But, salinity (EC) has increased towards Kerman city and the center of the plain, so that the maximum of the groundwater salinity was observed in Zangi Abadi, Karim Abad, and Akhtyar Abad. Groundwater depletion was not the same in all regions of the plain, so that the groundwater level has increased in the northeastern of the plain. Also the evaluation of soil quality index showed that the total amount of soil organic carbon does not exceed one percent in most cases. In Mahan, phosphorus concentration has increased significantly in soil surface layers (0-15) compared to other depths.
