A long-term (1933–2022) record of water level (WL) fluctuations in Lake Kinneret was reviewed. The dependence the WL management on climate change (flood–dryness alternate), dam and National Water Carrier (NWC) constructions constrained by availability domestic supply demands were indicated. short-term range maximal decline 4–6 m 4.6–6.5% total surface area lake shrinkage documented. Nevertheles...

The Jackson Lake Dam was constructed in 1917 in the Grand Teton National Park near Jackson, Wyoming. The dam was a hydraulic fill placed on a natural alluvium and outwash foundation. The Bureau of Reclamation (Burec) determined that the dam and its foundation would be susceptible to liquefaction and failure during a potential earthquake; a series of contracts was let to remove and replace the d...

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...
