| پخش سیلاب در مناطق نفوذپذیر یک استراتژی مناسب برای مهار سیلاب و بهرهوری از آن است. تعیین مکان مناسب برای پخش سیلاب، خود یکی از مهمترین مراحل انجام این گونه پروژهها میباشد. در این مقاله مناطق مستعد پخش سیلاب در دشت شبستر بر اساس چهار عامل شیب، نفوذپذیری، ضریب قابلیت انتقال و ضخامت آبرفت خشک (غیراشباع) مکانیابی شد. بدین منظور، با استفاده از دادههای لاگهای حفاری و اطلاعات چاههای پیزومتری، اکتشافی و بهرهبرداری موجود در منطقه، لایههای اطلاعاتی پارامترها در سیستم اطلاعات جغرافیایی (نرمافزار 10Arc GIS) تهیه و سپس این نقشهها با هم تلفیق شد. بر اساس نتایج بدست آمده مشاهده میشود که بیشترین مساحت از کل محدوده آبخوان برابر با 794/192 کیلومترمربع (153/40 درصد)، دارای استعداد پخش سیلاب مناسب و کمترین وسعت معادل 046/61 کیلومتر مربع (714/12 درصد) از مساحت آبخوان در محدوده خیلی مناسب قرار میگیرد. | ||

| چکیده [English] | ||
| Water spreading on the permeable areas is an appropriate strategy for flood control and efficiency. Determination of appropriate site for water spreading is one of the most important stages of such projects. In this paper, suitable areas for water spreading in Shabestar plain were determined based on four parameters including slope, permeability, transmissivity and unsaturated alluvium thickness. For this purpose, by using data of drilling logs from exploration and piezometric wells in the area, layer parameters information was prepared in geographical information system (Arc GIS 10 software) and then maps were combined together. The results showed that the maximum area of the aquifer with 192.794 square kilometers (40.1 percent), had suitable condition for water spreading and 146.512 square kilometers (30.5 %) of the aquifer, had moderate condition. As well as 79.786 square kilometers (16.6 percent), had unsuitable condition for water spreading and 61.046 square kilometers (12.7%) of the aquifer had quite suitable condition. | ||
