Geographic Analysis of the Climatic Water Balance in the Shahrazur Plain

Abstract

This study aims to determine the water budget in the Shahrazur Plain region, to determine the level of water surplus and water deficit, and to determine the best strategies to benefit from periods of water surplus in the agricultural sector. The study is expected to contribute significantly to improving the use of water resources and developing agriculture in the region The study included three stations using climate data during the period (2008-2020).3) and equations were applied (Penman-Thornthwaite-Sheep) to calculate the water budget. The study indicated that there were two periods Two different things In the distribution of the water budget, the results of the Penman-Montez equation varied during the period of water surplus, which extends from the month of November until the end of March, and the total annual water increase amounted to (356.4) mm in the Sulaymaniyah station, and (329.5) mm in the Helbaja station, and (315.7) mm at Darbandikhan station, and (333.8) mm on average. By Thornthwaite's method, the periods of water increase when calculating PE extends from November until the end of April, and the total annual water increase reached (485.47 - 454.0 - 432.9 - 457.45) mm, respectively, at the stations. But in a sheep way Periods of water increase when calculating PE extends from a month December To the end March, with the exception of Sulaymaniyah station, from November until the end of March The total annual water increase was(336.5- 297.37- 265.0-295.0 mm respectively at the stops For the period of water deficit, So it stretchesFrom April until the end of October, according to the Penman-Monteith equation, the total annual water deficit was respectively(660.9) mm at Sulaymaniyah station, (675.0) mm at Halbaja station, (707.6) mm at Darbandikhan station, and (668.16) mm on average. Using the Thornthwaite equation, the period of water deficit extends from May until the end of October, and the total annual water deficit was respectively (716.17 - 1016.4 - 1206.94 - 979.83) mm on. As for And using Equips sheep The period of water deficit extends from one month April to the end December, with the exception of Sulaymaniyah station, until the end of November the total annual water deficit reached (1577.4 - 1717.0 - 1873.3 - 1718.2) mm, respectively, in the stations.
