The Zerebar Lake is a shallow freshwater lake located in the northwestern Iran. The lake is surrounded by three human activities: agriculture, tourism and dam. The present study aimed to investigate (1) which human activity has the greatest impact on eutrophication of the Zerebar Lake (2) If phytoplankton communities, as the indicator, are correlated with the human activities. Water samples wer...

In this study, otolith morphology and otolith contour from big-scale sand smelt, Atherina boyeri were analyzed in Lake Eğirdir and Lake İznik (natural lakes), and Hirfanlı Dam Lake (artificial lake). The otolith contour and sixteen otolith morphological characters such as width, depth, shape, sulcus acusticus shape, ostium, cauda, rostrum size-shape, and thickness, antirostrum size-shape, and t...

Data was collected on Nov. 6, 2009 at the ARL Lake Travis Test Station. The lake has an estimated maximum depth of 37 m [2]. As seen in Fig. 1, the lake has a nearby dam and hilly former river bed terrain that contribute to high reverberation. Fig. 2 shows the temperature and sound speed profiles—a relatively constant set of temperatures and speeds compared to the thermoclines from the July, 20...

Background; Contamination of water and soil through non-point sources such as road runoff causes environmental concern. The aim of this study is to determine the effect of Zanjan – Chavarzagh road on the total organic carbon (TOC) content of sediments in tributaries and the river that lead to Taham Lake. Methods; In tributaries and the river 69 soil and sediment samples were taken and the Tota...

we collected silver bream blicca bjoerkna from march to july 2013 from aras dam lake (north-west of iran) and investigated its age, size, and some biological characteristics. the maximum age was 5 + years. the total length and weight of specimens ranged 137-278 mm and 26-247 g for male and 134-282 mm and 26-289 g for female, respectively. length-weight relationship was estimated as w = 1e-06tl ...

New field evidence and discharge calculation procedures provide new estimates of maximum late Pleistocene glacial Lake Missoula flood discharges for two important reaches along the flood route. Within the Spokane Valley, near the point of release, the peak discharge probably exceeded 17 ± 3 million m-sec. Downstream at Wallula Gap, a major point of flow convergence, peak discharge was about 10 ...
