Investigation on some water, soil and vegetation characteristics for biological reclamation in the wet edge of Kashan desert

To study water, soil, and vegetation characteristics in the wet edge of Kashan desert, 11 sites were selected and the data including water quantity and quality, soil, groundwater level, and vegetation types were collected. By drilling the wells, the water level was measured in different months of the year. In order to study the quality properties of water and soil, water samples were taken in two wet and dry seasons and soil samples were taken from nearby wells.The results showed that the minimum and maximum depth levels of water for the study wells were obtained at a distance of 47 cm in the well no. 3 and 299 cm in the well no.4, respectively. Fluctuations in water level of wells during the year were not so much, calculated to be 15 cm. The highest and lowest soil EC was 174 and 6.6 dS.m-1, respectively. The minimum and maximum water EC was 4 and 128 dS.m-1. In general, water depth was increased and EC was reduced by moving away from the lake. With considering the establishment of plants in the area with a salinity less than 40dS.m-1, 3880 hectares (23% of the study area) is suitable for the cultivation of hydro-halophytes.
