As the largest service industry in the world, tourism plays a special role in sustainable development. Geomorphic tourism is known to be a segment of this industry with lower environmental impact and underlying causes that explain lower demand; therefore, it is essential to study, identify, assess, plan, and manage natural tourist attractions. As such, the present study assesses the ability of ...

Floods are both complex and destructive, in most parts of the world cause injury, death, loss agricultural land, social disruption. Flood susceptibility (FS) maps used by land-use managers land owners to identify areas that at risk from flooding plan accordingly. This study uses machine learning ensembles produce objective reliable FS for Haraz watershed northern Iran. Specifically, we test abi...
Aims: Land-use change due to human activities is one of the important issues in regional and development planning. The aim of this study was to detect land-use changes using Landsat TM, ETM+, IRS and ASTER satellite imagery. Methodology: In this quasi-experimental study, land-use changes in the Haraz watershed over a 23-year period were evaluated. For this study, images of 1992 TM, ETM + 2002, ...
Prioritization of sub-watersheds is very important and necessary in order to implement soil and water conservation practices. This study has prioritized 13 sub-watersheds based on morphometric and land use characteristics using RS and GIS techniques in Haraz watershed to identify erosion-prone sub-watersheds. Morphometric characteristics including bifurcation ratio, drainage density, stream fre...
Quantitation and evaluation of infiltration models are used in soil conservation, irrigation systems, hydrology investigations, watershed and watershed management systems. The purpose of this study was to estimate the infiltration by using statistical and experimental various models in two soils of plowed and without plowed in Haraz Technology and Development center paddy fields of Mazandaran p...
