بررسی جمع آوری و بررسی مطالعات و اطلاعات حوزه های آبخیز استان بوشهر بمنظور تهیه شناسنامه آبخیزها

In this project different factores were studied that to watershed sciences and factors those that in every manner are needed to full study of watershed and that, every prior information, maps and statistic subjects was gathered and analized studies such as pedalogy, physiography, Geology, Climatology, HydrologY, Landcapability and Economic- Social studies of basins and every accessible formation about watershed were gathered. Whereas mOst of mentioned instances provided by executor and et al. At first, the large watersheds of province were performed on topographical maps in scale of 1:250000 that consist of 10 large watershedes and 10 coastal basin that recent drainages haven't single outlet and enter to persian Gulf. Amoung large watersheds, the widest is Mond basin with 48000 Km2 of it's area is located in Bushehr province. There are 3 watersheds of mond-e-sofla with 2800 Km2 area, shour Khormuj River basin with 1560 Km2 and Baghan ril1er with 940 Km2 area.The other large basins in Busher provinve are: watershed of Dalaki River, Shahpoor river, Watershed of Ahram River, River basin of shour Genaveh, Dareh- Gap basin and Dareh Abdary basin. In addition to extent, the basin were studied from the viewpoint of slope, hypsometry and other parameters and shown that north west and coast locations of province were formed low slope lands (<%1) elevations are less than 500m central and south west basins have several slope class and various topography.The results show That mond River has the largest watershed basin and that,the most Flood water in the rain seasons. but in arid Seasons because of decreasing water volume. water quality is being so undesirable so that it can't use even for agriculture. After that, shapour and Dalaki basins are in second place from view point of extent finally both unite and form Helleh river basin. The quality of shahpour's water is desirable and use as a fresh water but Dalald River is irrigable for date palms. In this project, the climate of Bushehr province studied and showed that because of it's presence in 28-30 latitud, precipitation is very low (average 220mm/year) and from north west east of province, this lvel becom lower so that annualy reaches to 150mm. for the reason of locating. this province alonge north- south and the low width, it hasn't various climtlte and it can be devided in to two zones arid and semiarid.The field methods of this project were as: the information were gathered by keeping in touch with different adminstrations that in any way related to watershed management and consulting engineers in province those had studies on this case. then those were gathered in diffrent form but on the basis of separating watersheds were regulated. After regulating schedul and providing maps,regarding the goal of project that is introducing an indicator watershed for constructing research stations of watershed,it seems repecting conditions possibilities and the situation of all the watershed, the Baghan river has a better condition for this purpose.
