During a survey of Gahar Lake and Gahar River from 2008 to 2009 some specimen obtained by seasonal sampling in 6 stations, 3 stations in the lake and 3 stations in the river. Three different methods were used for sampling, gill net and hook in the lake and electrofishing in the river. Due to the results 3 species from 2 families in Gahar Lake and 12 species form 3 families in Gahar River were...

Simulation of the runoff-rainfall process in forest lands is essential for land management. In this research, a hydrologic modelling system (HEC-HMS) and artificial neural network (ANN) were applied to simulate rainfall-runoff (RRP) Kasilian watershed with an area 68 square kilometres. The HMS model was performed using secondary data rainfall discharge at climatology hydrometric stations, Soil ...

This article presents six probability distributions from the gamma family with three parameters for flood frequency analysis in hydrology. The choice of statistical was driven by its frequent use In Faculty Hydrotechnics, improvement estimation maximum flows, including methodological bases realization a regionalization study linear moments method corrected parameters, researched and is an eleme...

This study used the standardized precipitation index (SPI) and runoff (SRI) to analyze dry humid conditions in hill-country catchment area of Laborec River (Slovakia) over a period 50 years (1970–2019). Analysis SPI SRI various time scales showed occurrence wet periods (index > 1.0) that were associated with exceeding long-term norm, below −1.0), which result small amounts precipitation. cor...

In August 2007, several horses showed pyrexia and respiratory signs while in post-arrival quarantine in Australia. Subsequent investigations diagnosed equine influenza by serology and PCR in two quarantine stations. A common origin in a shipment of horses from Japan was indicated.

The Sleepers River Research Watershed (SRRW) in Vermont, USA, has been the site of active hydrologic research since 1959 and was the setting where Dunne and Black demonstrated the importance and controls of saturation-excess overland flow (SOF) on streamflow generation. Here, we review the early studies from the SRRW and show how they guided our conceptual approach to hydrologic research at the...

Background & Aims of the Study: Due to widespread dust-storms in the western regions of Iran and the significant role of meteorological parameters in formation and control of these storms, this study aimed to explore the correlation between meteorological parameters and dust-storm occurrences in the western part of Iran. Materials & Methods: In this cross-sectional study, meteorological param...

Schools often offer healthy fruits and vegetables (FV) and healthy entrées. However, children may resist these efforts due to a lack of familiarity with the offerings. While numerous exposures with a food increase its liking, it may be that an exposure to a variety of FV at home leads to greater willingness to select other foods - even those that are unrelated to those eaten at home. As an init...

In this work, spatial and temporal variations in the diversity (species richness and Simpson's Diversity Index) and abundance (indexed by the capture per unit effort--CPUE; total and for reproductive groups) of fish from three rivers (Baía, Ivinheima and Paraná) located in a floodplain of the Upper Paraná River basin were analyzed over a period of 20 years (1987-2007). In addition, we evaluated...
