· Poyang Lake is loed in Jiangxi and is the largest freshwater lake of China, 73km long longitudinally and wide latitudinally on average, with a lakeshore length of 1,200km, a surface area of 3,583 km2 (outlet level ), an average depth of, a maximum depth of and a volume of about billion m3.

Novel foraging by wintering Siberian Cranes Leucogeranus ...
Novel foraging patterns by Siberian Cranes were associated with low densities of Vallisneria tubers across multiple sublakes within Poyang Lake National Nature Reserve (PLNR). Foraging success was higher in grasslands than in wetlands in winter 2010–2011, but higher in wetlands following a recovery of Vallisneria in 2011–2012.

· Poyang Lake, Dongting Lake and Shengjin Lake are three extremely important lakes for abundant waterbirds including species of conservation concern (Barter et al. Reference Barter, Chen, Cao and Lei 2004, Reference Barter, Lei and Cao 2006, Ji et al. Reference Ji, Zeng, Wang, Gong, Xu and Bao 2007, Lei et al. Reference Lei, Lei, Tao and Hearn 2011).
Sandstone Reservoirs | SPE International Oil and Gas ...
The origin and distribution of a sandstone reservoir for petroleum are controlled primarily by the processes by which the sand was deposited. Studies of modern environments of deposition and associated Holocene deposits provide a basis for understanding petroleum fields and predicting reservoir distribution and behavior.

What Are Oligotrophic, Mesotrophic, And Eutrophic Lakes ...
· Such lakes support aquatic species who require welloxygenated, cold waters such as lake trout. Oligotrophic lakes are usually found in the cold regions of the world where mixing of nutrients is rare and slow due to the low temperatures of the lake waters. Mesotrophic: Lakes with an intermediate level of productivity are called mesotrophic lakes.

Sand mining and increasing Poyang Lake's discharge ability ...
· Sand mining in Poyang Lake quickly developed into an industry involving hundreds of large vessels (de Leeuw et al., 2010, Wu et al., 2007). In this paper, we argue that the major determinant of lower lake levels during the past decade is primarily because of sand mining increasing Poyang Lake's discharge ability into the Yangtze River.
Reservoir
· Reservoir Porosity. Porosity is the void space in a rock that can store the fluids. It is measured as either a volume percentage or a fraction (expressed as a decimal). In the subsurface this volume may be filled with petroleum (oil and gas), water, a range of non hydrocarbon gasses (CO2, H2S, N2), or some combination of these.
9 Different Types of Septic Systems
The conventional model involves a large tank buried in the ground near the home or building that it will service. Using gravity, the wastewater that comes from the home drains into the tank. The water line in and out continues to drain liquid out from the tank to the ground which is known as the drain field.
