| چکیده مقاله |
| The amount of rain in or near this basin is very low and limited to the cold season. According to the summary of atmospheric statistics In different stations, there is no rain in the hot season, and the average annual rainfall in the cold season in Kerman is 110. It is 40 mm in Bam, 78 mm in Zahedan, 45 mm in Zabul and 180 mm in Birjand. The annual average temperature in these areas is relatively high, and for this reason, the amount of evaporation in the hot season increases sharply, especially in the Lut Plain. The amount of annual rain in the heights near the plain is slightly more than the figures recorded above, but the amount is not significant. There are few snow-bearing peaks and their snow melts quickly at the end of the cold season or at most at the beginning of the warm season; Therefore, the only source of water for rivers and canals is, firstly, the rains of the cold season and then the springs that are scattered in the upper part or the middle of the canals. About 20 kilometers from Shahdad, trees and Gaz shrubs are located in desert pots of Lut, which are called Nebka or plant mounds. The lands between the nabkas are covered with sand, and the nabkas generally appear on a flat surface where the amount of sand is medium and the water level under the ground is high or the available moisture is sufficient for the life of the vegetation. Nebka constituent elements include sand-lay, clay and celt. |
