mean flow and turbulence in compound channels with vegetated floodplains
the study of flow in compound channels with vegetated floodplains is essential to assessing the development of the stage-discharge relationship and sediment and pollutant transport. the present study experimentally investigated mean flow and turbulence characteristics in a prismatic compound channel. the experimental program consisted of vegetated and non-vegetated floodplains with different re...

بیشتر تحقیقات پیشین در زمینه تمایل به برقراری ارتباط به رابطه آن با عوامل فردی چون سن، جنس، نوع شخصیت و... صورت گرفته است. در صورتی که مطالعات کمتری به بررسی رابطه تمایل به برقراری ارتباط زبان آموزان فارسی زبان با ترس از برقراری ارتباط و توانش خود ادراکانه آنها در برقراری ارتباط در محیط فارسی و انگلیسی انجام شده است. بر اساس نظریه الیس (2008) تمایل به برقراری ارتباط جایگاه مهمی در زمینه آموزش م...
15 صفحه اولDetermination of flow resistance of vegetated channel banks and floodplains
Flow resistance due to vegetation may greatly affect the conveyance of a channel, and thus evaluating the resistance is a critical task in river engineering and restoration. Therefore, flow resistance of natural willows and sedges was studied in a laboratory flume. The aim was to investigate, how type, density and combination of vegetation, flow depth and velocity influence vegetal drag or fric...
متن کاملUnsteady 1D flow model of a river with partly vegetated floodplains - application to the Rhine River
A relatively simple unsteady flow model was proposed which estimates velocities, friction factors and the components of discharge in the main channel and on the floodplains simultaneously. Bottom roughness of the main channel and the floodplains, the flow resistance of vegetation on the floodplains and the flow resistance caused by the momentum transfer between the main channel and the floodpla...
