Abstract Background and purpose: Urban developments and population growth have dramatically increased all kinds of municipal solid waste (MSW) generation. Hence, treatment and disposal of municipal waste is one of the main concerns in urban environmental management. The aim of this study was to determine suitable locations for landfill based on environmental criteria using Boolean and Weight...
Paraschistur anielseni is one of the main species of Paraschistura genus that is distributed in freshwater rivers which drain into the Persian Gulf. There has not been any study on genetic diversity of this species yet. In this investigation, 90 samples were collected from the rivers Shapour, Dalaki (Fars province) and Mand (Bushehr province) (30 samples per river) to investigate their populati...
Incorporating spatial covariance into clustering has previously been considered for functional data to identify groups of functions which are similar across space. However, in the majority of situations that have been considered until now the most appropriate metric has been Euclidean distance. Directed networks present additional challenges in terms of estimating spatial covariance due to thei...
Recently, Luciobarbus conocephalus from the Hari River was reported for the first time, but there is doubt about the validity of this species between authors, because some of them placed it as a subspecies or synonym of L. capito. Therefore, the present study was conducted to investigate the status of phylogeny and the validity of this species. For this purpose, specimens captured from Hari Riv...
[1] Erosion by bedrock river channels is commonly modeled with the stream power equation. We present a two-part approach to solving this nonlinear equation analytically and explore the implications for evolving river profiles. First, a method for non-dimensionalizing the stream power equation transforms river profiles in steady state with respect to uniform uplift into a straight line in dimens...
The effect of Palangan fish farms on water quality of Sirvan River was investigated using physicochemical and biological indicators from January 2015 to June 2015. Five stations were determined including 1) before the fish farm 2) after the fish farm effluent 3) sub-branch 4) 100 meter after fish farm effluent and 5) 1000 meters after fish farm effluent. EC showed significant differences in dif...
Genomic DNAs isolated from crucian carp of four rivers, belonging to the family Cyprinidae was amplified by seven oligonucleotides primers. In the present study, we employed hierarchical clustering method in order to reveal genetic distances and variations. Crucian carp was acquired from Hangang river (CAH), Geumgang river (CAG), Nakdonggang river (CAN) and Yeongsangang river (CAY). The primer ...
Land cover maps derived from satellite images play a key role in regional and national land cover assessments. In order to compare maximum likelihood and minimum distance to mean classifiers, LISS-III images from IRS-P6 satellite were acquired in August 2008 from the western part of Isfahan. First, the LISS-III image was georeferenced. The Root Mean Square error of less than one pixel was the r...
This study describes the species diversity of fishes of the Narmada River in India. A total of 820 fish specimens were collected from 17 sampling locations across the whole river basin. Fish were taxonomically classified into one of 90 possible species based on morphological characters, and then DNA barcoding was employed using COI gene sequences as a supplemental identification method. A total...
The subject of the study is to analysis pattern of Mahabad River channel. This area is located on the south of Uromia Lake. Rapid changing of its channels pattern is an important characteristics which the evaluation of these characteristics is necessary to any hmplementation of development projects. For this purpose, the morphological changes of river channel were recognized by the areal photog...
