Estimation of the magnitude and frequency of maximum instantaneous discharges and hydrographs are used for a variety of purposes, such as the design of bridges, culverts, flood-control structures; and the management and regulation of floodplains. Fuller (1914), developed a flood-frequency formula based on analysis of flood peaks in hundred of streams to provide simple methods of estimating maxi...
Nowadays, the satellite data and remote sensing technologies are widely known as efficient tools for the inspection, identification and management of land resources and precision agriculture in most countries. Satellite information could be used in supplying basic and updated information in the estimation of vegetation cover map, irrigated land area and some biological indices of the major agri...
این پژوهش بهمنظور ارزیابی تنوع 70 ژنوتیپ جو از لحاظ مقاومت به بیماری سفیدک پودری (powdery mildew) انجام گرفت. پس از تهیۀ نمونههای آلوده به بیماری، تکثیر اسپورهای قارچ بر روی رقم حساس افضل صورت گرفت. آزمایش در قالب طرح بلوکهای کامل تصادفی بهصورت گلدانی در گلخانه انجام گرفت. گیاهچهها در مرحلۀ دوبرگی با اسپورهای قارچ مایه‌زنی شدند. دوازده روز بعد صفات تیپ آلودگی و درصد آلودگی برگها براساس مق...
Nowadays using field depth measurement to estimate capacity of water reservoirs is a costly and time consuming method. In this regard, different multiple techniques of remote sensing method has been adopted. In this study, a radiation and reflection based model was introduced to estimating the bathymetry and water capacity of reservoir by images of OLI sensor. For this, at May 17, 2015 water de...
