Reservoirs are a crucial part of the human water supply system. The effectiveness and service life reservoir is decided mainly by its storage capacity, as such, preventing capacity loss high interest worldwide. Due to climate change in recent years, precipitation types have changed, heavy rainfall events become more severe frequent. Rainfall causes soil erosion slope lands transports large amou...

In order to explore the water level variations of Caizi Lake under river-lake isolation, monthly Chefuling station in from 1989 2018 and daily level, rainfall flow local hydrological stations were analyzed by using Mann-Kendall trend test wavelet analysis. Results showed that difference average between flood dry seasons was 3.34 m, with a multi-year 10.42 m above sea level. The first second mai...

The European eel (Anguilla anguilla (L.)) is critically endangered after a multi-decadal decline. Anthropogenic disruption to downstream migration, including at water control structures such as pumping stations, thought be one of the contributing factors. Some stations only operate during floods and river drains through sluice gates under influence gravity (‘gravity sluice’ hereafter) all other...

Passage success of sea lampreys Petromyzon marinus and behaviour in the vicinity man-made structures such as marine–freshwater barriers are poorly understood. To mitigate these migratory problems, a better understanding passage is needed. investigate this, 25 were tagged with V7 VEMCO acoustic transmitters at large marine-freshwater barrier, consisting ten sluice gates ship lock complex Netherl...

A new method has been described for measuring the pressure and resistance to blood flow in the pulmonary arteries, capillaries, and veins. Studies were performed in dog isolated lung lobes perfused at constant flow with blood from a donor dog. Pulmonary artery and vein volume and total lobar blood volume were measured by the ether plethysmograph and dyedilution techniques. The longitudinal dist...
