Investigation into Multi-Temporal Scale Complexity of Streamflows and Water Levels in the Poyang Lake Basin, China
The streamflow and water level complexity of the Poyang Lake basin has been investigated over multiple time-scales using daily observations of the water level and streamflow spanning from 1954 through 2013. The composite multiscale sample entropy was applied to measure the complexity and the Mann-Kendall algorithm was applied to detect the temporal changes in the complexity. The results show th...
متن کاملIntegrating Ecological Restoration of Agricultural Non-Point Source Pollution in Poyang Lake Basin in China
This study addresses the excessive consumption of river basin water from the Poyang Lake area in China. Consumption of water for irrigation, together with the discharge of agricultural non-point source pollution, is seriously affecting the water quality of Poyang Lake. This study assesses the application of integrated ecological restoration technology for agricultural non-point source pollution...
متن کاملSpatiotemporal Characteristics of Dry-Wet Abrupt Transition Based on Precipitation in Poyang Lake Basin, China
The dry-wet abrupt transition (DWAT) is a typical anomaly of precipitation at the subseasonal scale and may result in a severer and greater hydro-meteorological hazard. This paper identified and examined the DWAT events in terms of precipitation in Poyang Lake basin, including both from dry to wet (DTW) and from wet to dry (WTD), during the period of 1960–2010 and analyzed its characteristics o...
متن کاملEffects of climate change on annual streamflow using climate elasticity in Poyang Lake Basin, China
Hydrological processes depend directly on climate conditions [e.g., precipitation, potential evapotranspiration (PE)] based on the water balance. This paper examines streamflow datasets at four hydrological stations and meteorological observations at 79 weather stations to reveal the streamflow changes and underlying drivers in four typical watersheds (Meigang, Saitang, Gaosha, and Xiashan) wit...
متن کاملSpatial Variability of Greenhouse Gas Effluxes and Their Controlling Factors in the Poyang Lake in China
CO2, CH4, and N2O (GHG) emissions are globally important in China, but few field observations have been made in freshwater lakes. In this paper, we measured the GHG effluxes from 44 sampling locations among four sub-regions in Poyang Lake in China in October 2010 using floating chambers. The mean CO2, CH4, and N2O effluxes were 0.23 μmol m ·s, 3.0 nmol·m·s, and 0.11 nmol m·s, ranging from -0.25...
