Macroplastic fate and transport in the freshwater environment are of great concern due to the
potentially harmful effects of macroplastic on plants, animals, and humans. Here, we present …

The effect of the elliptic ratio on the hydraulic performance of the LOPAC gate has been
investigated using experimental and Computational Fluid Dynamics CFD simulations (Flow …

A sharp-crested weir with power-law sides is a general form, which reduces to the wildly
used rectangular, parabolic, and triangular weirs. This general form allows modeling the …

This study intended to investigate the hydraulic performance of the new types of LOPAC
gates, namely the elliptical LOPAC (EL) gate, and the rectangular LOPAC (RL) gate for …

Gates are usually made with a width smaller than the width of the canal to reduce
construction and operation costs. In this study, the effect of a sudden contraction of the canal …

Weirs are structures that allow uppermost layers of liquids to flow by gravity downstream.
They are, therefore, inherently gravity skimmers, and have successfully been used as …

Measuring and controlling flow in conduits is one of the most important issues in the
management and operation of irrigation and drainage systems. Investigations on this issue …

Management of irrigation networks has always been one of the most important issues in the
agricultural sector, and the use of modern valves and structures for controlling and adjusting …

در این پژوهش به بررسی اثر پارامتر های هیدرولیکی جریان بر روی دریچه های سالونی بیضوی
چندگانه در شرایط جریان مستغرق پرداخته شده است. این بررسی با استفاده از نرم افزار شبیه …‎

دریچه سالونی به عنوان سازهای نوین دارای مزایایی از جمله روگذر بودن و عبور رسوبات و شاخ و برگ
