Abstract The impact of climate change on water availability has become a significant cause for concern in the Zayandeh-Roud Reservoir Iran and similar reservoirs arid regions. This study investigates supply River Basin. For better management, Soil & Water Assessment Tool (SWAT) was used to develop hydrologic model basin. then calibrated validated two upstream stations using Sequential Uncer...

Introduction Trend of increasing natural resource degradation in many parts of the world, is a serious threat to humanity. Desertification is one of the manifestations of the damage that has already suffered as a scourge of many countries, including developing countries are. At present, remote sensing is one of technologies with timeliness data and accuracy suitable for monitoring land use c...

Zoning the pollution of a river may be the first or even the most important step in water quality management. In order to resolve its pollution, fuzzy clustering analysis may be used whenever a composite classification of water quality incorporates mutiple parameters In such cases, the technique may be used as a complement or an alternative to comprehensive assessment. In fuzzy clustering ...

Amphibolite rocks with mylonitic texture exposed in the NE of Yan- Cheshmeh village (SE of Zayandeh-Rud Lake). Mineralogy of rocks include amphibole, plagioclase, quartz, rutile, clinozoesite, chlorite, titanite, biotite and opaque. Amphiboles are seen as fish. Basic igneous rocks are protolith of the amphibolites that have subalkaline nature. Ni (299-370 ppm), Cr (1169-1900 ppm) and SiO2 (44.9...

Aphaniusisfahanensis is a new endemic killifish species that has been described in the Zayandeh River of the Isfahan basin in Iran. During a study on the biology of nine fish from this species, the parasite Diplostomumspathaceum was observed in the aqueous humor of the eye of a single individual. It was visible as a white mass with a diameter of 0.38 mm. This is the first report on the infectio...
