Continual sediment accumulation in Capitol Lake since the damming of the Deschutes River in 1951 has altered the initial morphology of the basin. As part of the Deschutes River Estuary Restoration Feasibility Study, the United States Geological Survey (USGS) is modeling how tidal and storm processes will influence the river, lake and lower Budd Inlet should estuary restoration occur. Understand...

INTRODUCTION ROATH LAKE is a large artificial lake situated in one of the municipal parks of Cardiff, and well known as a pleasure-spot, for angling, boating, and for its waterfowl." Roath Park, in which. the lake is situated, is also noted for its recreational facilities and splendid botanical gardens, which include one of the finest rose gardens in Great Britain. An attraction of the lake up ...

Moraine-dammed lakes at debris-covered glaciers are becoming increasingly common and pose significant outburst flood hazards if the dam is breached. While moraine subsurface structure and internal processes are likely to influence dam stability, only few sites have so far been investigated. We conducted electrical resistivity tomography (ERT) surveys at two sites on the terminal moraine complex...

On May 12, 2008 a large earthquake occurred in Wenchuan, resulting in significant casualties and enormous property loss, and shocked the world. Then the Tangjiashan barrier lake caused by earthquake, made a serious threat to 1.3 million people living downstream. From its formation to being successfully disposed, the entire emergency management of Tangjiashan barrier lake lasted about a month. I...

On 26 May 2003, intense rainfall from a series of thunderstorms in eastern North Carolina caused flooding that eventually destroyed the concrete dam in Hope Mills, draining Hope Mills Lake, and revealing a formerly submerged and buried structure that was identified as a timber crib dam. Inspection revealed these logs to be old-growth longleaf pines, which are now rare on the coastal plain lands...

During 1997-2007 we studied distribution and dynamics of main radionuclides and their biological significance in lake ecosystems within the 10-km inner exclusion zone around the destroyed unit of the Chernobyl nuclear power plant. The main objects of our studies were bottom sediments, water, seston, and different species of hydrobionts from Azbuchin Lake, Dalekoye-1 Lake and Glubokoye Lake. Sel...

Ethiopia began constructing the Grand Ethiopian Renaissance Dam (GERD) in 2011 on Blue Nile near borders of Sudan for electricity production. The dam was constructed as a roller-compacted concrete (RCC) gravity-type dam, comprising two power stations, three spillways, and Saddle Dam. main is expected to be 145 m high 1780 long. After filling estimated volume water bounded about 74 billion m3. f...

Evaporation is one of the largest water losses from most of the dam lakes in Iran. Estimating the evaporation rate enables us to apply the proper evaporation mitigation technologies. In this study, the feasibility of different evaporation estimation methods was studied to find an optimum method with a fair tradeoff between cost and accuracy. The optimum method may vary depending on the climate....
