The distribution characteristics of vancomycin-resistant enterococci (VRE) and the resistance of enterococcus isolates to various antibiotics were investigated in Yae River, which flows through Miyazaki city, Japan. The prevalence of VRE among specimens collected from the urban river basin using mEI agar was 0.9% (2 of 226 enterococcal isolates). In the 333 enterococcal isolates obtained using ...

in prehistoric studies of iran, the abharrood river basin, located on the east of zanjan province and in the northwestborder of the central plateau, is one of the little-known and dark regions. studying this region according to itsenvironmental features and geographical location is important for understanding regional relations and interregionalinteractions between three cultural-geographical a...

Fish species of the Zungaro genus (Siluriformes, Pimelodidae) are amongst the largest migratory fish in Latin America and have considerable economic importance for commercial fishing in Brazil. However, natural populations of this large catfish are experiencing a severe decline. There are significant taxonomical inconsistencies for this fish. Two geographically separated species of the fi...

The effects of erosion, avalanching and random precipitation are captured in a simple stochastic partial differential equation for modelling the evolution of river networks. Our model leads to a self-organized structured landscape and to abstraction and piracy of the smaller tributaries as the evolution proceeds. An algebraic distribution of the average basin areas and a power law relationship ...

there are different methods of reconstructing hydrologic data. depending on the conditions of the station a particular method can produce the best results. generally, in order to estimate the lost data in a station and its surrounding stations, hydrologic, climatologic and/or physiolographic similarities are used. recently, the fuzzy regression method has been used to reconstract the hydrologic...

Located in the central Chinese Loess Plateau, the Jinghe River is one of the major tributaries of the Yellow River, and the river basin it inhabits is characterized by a continental climate. Considering that land degradation has been the main ecological problem in the Jinghe River Basin, there is an urgent need to scientifically explore the land degradation mechanism in order to restore natural...

Variations in climate, land-use and water consumption can have profound effects on river runoff. There is an increasing demand to study these factors at the regional to river basin-scale since these effects will particularly affect water resources management at this level. This paper presents a method that can help to differentiate between the effects of man-made hydrological developments and c...

[1] We investigated how climate, rising atmospheric CO2 concentration, increasing anthropogenic nitrogen deposition and land use change influenced continental river flow over the period 1948–2004 using the Community Land Model version 4 (CLM4) with coupled river transfer model (RTM), a global river routing scheme. The model results indicate that the global mean river flow shows significant decr...

occurrence of lernaea parasite in a narrow distributed endemic fish, chondrostoma orientale (oriental nase) restricted to the kor river basin, southwestern iran is reported. based on the obtained results, all three collected specimens (tl= 174-192mm, sl= 148-169mm) were infested with lernaea parasites which were attached to the base of dorsal, pectoral, caudal and pelvic fins and also body musc...

This study has shown that increasing levels of insecurity often arise from basin closure. This was subsequently shown to be the situation in the South African case study, particularly in the Incomati River basin and to a lesser extent the Limpopo River basin. This study has also shown that these increasing levels of insecurity could result in the securitization of water resource management, whi...
