Glacier surges in the north-west West Kunlun Shan inferred from 1972 to 2017 Landsat imagery

Evaluation of Matched Filter method for wind erosion mapping Landsat 8 OLI Imagery, (Central and North West province of Khuzestan)

Successful target detection, especially if there is a similarity between the target and the background area, always is a noticeable issue in remote sensing studies. Because of the spectral behavior similarity to the other phenomena and spatial distribution of these units, the mapping of wind erosion units is difficult. Thus, this study attempts to detect the favorable areas by using matched fil...

Automated Extraction and Mapping for Desert Wadis from Landsat Imagery in Arid West Asia

Wadis, ephemeral dry rivers in arid desert regions that contain water in the rainy season, are often manifested as braided linear channels and are of vital importance for local hydrological environments and regional hydrological management. Conventional methods for effectively delineating wadis from heterogeneous backgrounds are limited for the following reasons: (1) the occurrence of numerous ...

Protozoan from freshwater fishes from North West of Iran

During a parasitological investigation on the fresh water fishes of North West of Iran (West Azerbaijan Province), 266 specimens of 11 fishes were examined. Fishes were collected from seven stations from Aras, Zangbar and Sarysou Rivers between summer 2001 to summer 2002. Nine protozoan species were detected; eight Cilliophora and one Rhizopoda. Cilliophora are: Chilodonella sp., Apiosoma sp.,V...
