The Mesopotamian spiny eel, Mastacembelus mastacembelus, an endemic freshwater fish restricted to the Euphrates and Tigris river drainages of Mesopotamian, its related taxa in Afrotropica South Asia present suitable elements for studies evolutionary history mastacembelids across these heterogeneous areas. To understand clarify geographic variation eel from Persian Gulf basin, we investigated mo...
Background and purpose: Ticks, as ectoparasites, biological vectors and reservoirs of various diseases, are involved in transmission of pathogens to humans and animals. This research aimed at modeling the probability of tick vectors presence in Ahvaz, Hamidiyeh, Bavy, and Karoon in southwest of Iran. Materials and methods: To perform the modeling, eight criteria (slope, elevation, soil texture...
Analysis of low flow is one of the important considerations in any water resource project. Meanwhile, as a general idea it seems that flow control is more important than drought mitigation but it is necessary to pay more attention to drought problem in future projects. In this paper, available data for 28 selected watersheds were analyzed and then Flow Duration Curve was drew, and discharge of ...
Organic matters in raw water have a potential to generate harmful disinfection by-products such as trihalomethanes (THMs) during the chlorination process. The objectives of this study were to investigate the trihalomethane formation potential (THMFP) in Karoon River water and to determine the effect of several factors including total organic carbon (TOC), pH, chlorine dosage, water temperature,...
Environmental pollution is a world-wide problem, heavy metals belonging to the most important pollutants. The progress of industries has led to increased emission of pollutants into ecosystems. Karoon is the biggest and only navigable river in the South of Iran. Along the Karoon industrial units such as piping, steel, paint making, agriculture, paper mill, fish cultivation, abbottiors, electrop...
Many sediment transport equations have been developed for estimation of the river sediment materials during the past four decades. There are significant differences in the results from these equations when applied to compute sediment transport for a specific river. Therefore, application of an equation for estimation of a river sediment load is not an easy task. In this study, 12 important sedi...
Rivers are discussed as sources of water supply for various uses including agriculture, industry anddrinking. Thus, monitoring the quality of these resources due to the recent drought and urban and ruraldevelopment is one of the important tasks in the field of environmental management. In this study,nine stations sampled seasonally the Karoon river, Dez, Karkheh in a one-year period from Octobe...

Background & Aims of the Study: Vegetables are useful for humans as they contain minerals, vitamins, fiber and other nutrients. Eating raw vegetables are a nutritional habit in Iranian families. Raw eating vegetables is the main source of parasitic infections. The aim of this study was to determine microbial contamination of raw vegetables in Ahvaz, Iran during 2014-2015. ...
