While mapping the American Falls region, we found evidence that contributes to the middle Pleistocene to Recent history of the Snake River, and indirectly to the history of overflow of Lake Bonneville. Middle Pleistocene to recent rocks in the valley are mainly lacustrine and fluvial silts and clays, with some sand, gravel, basalt, and a few thin tuff beds. The formation of terraces can be corr...

The Monasavu catchment was selected as an additional study site for biodiversity assessment at the top of the PABITRA wet-zone landscape transect on Viti Levu. The site consists of upland rain forest with cloud forest and a freshwater lake. The lake was constructed to supply hydroelectric power. The biota of the area has been little studied, but initial surveys indicate that many endemic specie...

Lakes are an important part of the Earth’s surface. Poyang Lake is China’s largest freshwater lake with complex hydrological relationships and unique rhythmic changes. There no systematic understanding relationship between watershed area river–lake connectivity. In this study, using remote sensing imagery, data, meteorological land use surveys, we investigated changes in water from 1977–2021. a...

Abstract. The existence of glacial lakes in the southeastern Tibetan Plateau (SETP) is a potential hazard to downstream regions, as outburst such has result disastrous lake floods (GLOFs). In present study, we conducted comprehensive investigation Bienong Co, moraine-dammed SETP. First, basin morphology was determined, and volume estimated, showing that maximum depth ∼181 m ∼102.3×106 m3. These...

a study with travel cost method (tcm) was performed to evaluate ecotourism demand of lake belonging to karoon 3 dam. for this purpose, 220 clawson questionnaires at highest demand time (february to may 2008) were completed. results of this investigation showed that forecasting outdoor recreational value of karoon 3 dam limits is equal to 2,879,550,000 rials at month, during study. in order to p...

THE HUGE THREE-GORGES DAM (TGD) OF THE Yangtze River is going to demonstrate the mighty power of humanity to change and fragment an area of about 58,000 km2 with the formation of a huge reservoir of 1080 km2. It is expected to exert disastrous influences on many terrestrial plants and animals, as discussed by J. Wu et al. in their Policy Forum “Three-Gorges Dam— experiment in habitat fragmentat...

K-water installed the first domestic 100kW floating photovoltaic system on the water surface of multipurpose dam reservoir in October 2011. Also, it installed a 500kW floating photovoltaic generation facility nearby in October 2012 for commercial power generation. Based on these, it installed a 10kW marine photovoltaic generation facility at Sihwa Lake in October 2013. In this paper, static loa...

Water resources management is one of the most important issues and challenges in world. This may be form quality or quantitative water resources. Quality great importance. A major problem this case how input flow (for example a river) will behave when flows to dam reservoir lake. Distribution stream reservoir/lake depends on parameters such as inflow discharge, depth, situation type outlet, inl...

Fresh water resources are depleting at a fast rate throughout the world affecting diverse aquatic flora and fauna. Algal responds to adverse changes in habitat which is reflected by their morphotaxonomical deformation occurrences of pollution tolerant taxa changed habitat. Based on findings more than five decades, it has been established that such labeled as bioindicator because tolerance. Taki...

Extensive efforts are underway to reduce phosphorus (P) export from the Lake Erie watershed. On Canadian side, Thames River is largest tributary source of P Erie’s western basin. However, role dams in retaining and modifying riverine loading lake has not been comprehensively evaluated. We assessed whether Fanshawe Reservoir, dam reservoir on River, acts as a or sink P, using year-round discharg...
