Forest stock volume (FSV) is a major indicator of forest ecosystem health and it also plays an important part in understanding the worldwide carbon cycle. A precise comprehension distribution patterns variations FSV crucial assessment sequestration potential optimization management programs sink. In this study, novel vegetation index based on Sentinel-2 data for modeling with random (RF) algori...

in order to evaluate the possibility and compare different irrigation methods in ricecultivation, an experiment was conducted in factorial based randomized complete blockdesign at rice research institute of iran, mazandaran (amol), during 2011. treatments weredifferent irrigation regimes including alternate wet and drying (awd), semi-dry cultivation(sdc), combining shallow water depth with wett...

Volume based pricing in irrigation is an important application method solving excessive and illegal water use problems. It essential to a properly selected meter accurately measure the amount of water. In this study, system performance Kayack Water User Association (WUA) was comparatively analyzed for years 2012 2017. The prepaid has been used measurement Kayacık scheme since 2015. While it cou...

Investigation on structure and dynamics of natural forest ecosystems is an important issue for silvicultural decisions. The aim of this study is to analysis dynamics and structure of a beech stand during 5-year period in the Shast Kalateh forest in the Caspian region, North of Iran. Data were collected from a 16.9ha permanent research plot established in a natural unlogged stand in 2006. All li...
