the production and proper utilization of medicinal plants in natural habitats need to review and identify the natural conditions and climate of the habitat of these plants and separating them from harmful and poisonous plants. the current study was aimed to introduce and determine the distribution of medicinal plants from lamiaceae family in mazandaran province as well as the introduction of na...

The floods are an annual phenomenon on the Pacific Coast of Ecuador and can become devastating during El Niño years, especially in the Guayas watershed (32,300 km2), the largest drainage basin of the South American western side of the Andes. As limited information on flood extent in this basin is available, this study presents a monitoring of the spatio-temporal dynamics of floods in the Guayas...

BACKGROUND Road safety and traffic accidents change in time and space. Although, time variations have always been considered the subject being focused by researchers, the effect of spatial correlation and spatial components on the risk of accident have been less investigated. Due to its specific geographical position, Mazandaran Province is one of the highest traffic provinces. This study aims ...

The limited flow data is an obstacle that often occurs in the analysis of water availability. To obtain this data, nowadays there are many prediction models for discharge. Remote sensing technology can improve development conventional rainfall–runoff relationship model studies. With technology, it help predict runoff discharge each Sub-watershed. Unda watershed one potential watersheds province...

This paper describes long-term hydrologic response within a rapidly developing watershed in the western suburbs of Washington, DC, within the Chesapeake Bay drainage basin. Data consist of up to 24 years of observed rainfall, basin discharge, and land use/land cover (LULC) from four headwater basins of the Occoquan River in northern Virginia. Basin outlets are monitored for storm and nonstorm f...

inappropriate patterns and drastic changes in land-use have caused the severe environmental crisis. therefore, it is necessary to accomplish any plan in relation to establishment of different activities with respect to land capabilities and land-use evaluation thought. in this study, ecological capabilities and the site selection of land uses in babolrood basin, mazandaran province were evaluat...

in iran, most mountainous watersheds do not have enough hydrometery stations and defective stations have sparse data. because of limited availability of hydrologic data, watershed modeling plays a crucial role in development of local resources. in this study, swat was applied to simulate runoff in marun dam (idanak) watershed, a sub-basin of marun catchment. calibration and sensivity analyses w...

This work studies the implementation of a simple mixing and geochemical model to assess the adoption of remediation measures in a highly AMD impacted watershed in SW Spain. The model provides a good snapshot of the impact of potential passive treatment plants on the water quality amelioration of this basin. The implementation of these plants in selected sites would reduce notably the level of m...
