Climate change and human actions will exacerbate eutrophication cases in inland waters. By external or internal inputs, there be an increase nutrient concentrations those systems worldwide. Those nutrients bring faster trophic changes to waters possible health recreational advisories. A novel approach using a floating filtration system, silt curtain, geotextiles (woven non-woven) is under inves...
Geosynthetic materials (i.e., geogrids, geotextiles and other geocomposites) act as an interlayer system are widely used in construction applications. In pavement structures, geosynthetic layers provide potential benefits such reinforcement, reflective cracking mitigation, increased fatigue life, improved drainage filtering. However, few studies have addressed the installation practices of geos...
Global warming has accelerated during the past decades, causing a dramatic shrinking of glaciers across globe. So far, attempts to counterbalance glacial melt have proven be inadequate and are mostly limited few landscapes only. In present study, scientific glacier protection experiment was conducted at Dagu Glacier site. Specifically, study site No. 17, situated 4830 m a.s.l. The involved deli...
Linseed flax is a multipurpose crop. It cultivated for its seeds and particularly oil. The main contributors this crop are Canada, France Belgium. In general, straws of linseed buried in the fields or burnt. However, these solutions not good practices environment from an economical point view. study, (six batches total) with different dew retting durations harvesting techniques were studied to ...
Enhancing the use of natural fibre for geotechnical purposes has attracted greater attention in past decade, mainly because tangible benefits that this green approach would bring to our sustainable infrastructure developments. While topic been subjected often sceptical review or discussions, they usually focus on narrow aspects such as soil reinforcement, resulting a lack thorough assessment ov...
منشأ بیش از 80 درصد (یا به عقیده بعضی 90 درصد) مشکلات درختان فضای سبز به مسایل بستر ریشه این گیاهان بر-می گردد. در محیط های شهری گسترش سیستم ریشه ای درختان به موازات رشد قسمت هوایی، صورت نمی گیرد و اغلب به دلیل محدودیت ها و مسایل خاک در دسترس گیاه، رشد ریشه ها محدود می شود. وجود شرایط بد بستر و استفاده از خاکهای فقیر در فضای سبز باعث مشکلات تغذیه ای بارز در درختان فضای سبز اصفهان شده است. به دل...
drain envelopes play significant roles in the performance of drainage systems due to theirreduction in letting sediments into the drainpipes and also because of an increase in thehydraulic conductivity of soil around the drainpipes. throughout the present research, theeffect of a one 1000 hour flow on dual envelopes consisting of geotextile as a means ofimproving the hydraulic gradient and rice...
