On the basis of estimates sediment accumulation in reservoirs, impact 50,000 dams on supply and intertidal wetland response Yangtze River catchment is examined. The total storage capacity reservoirs 200 × 10 9 m 3 , or 22% annual runoff. rate has increased from ∼0 1950 to >850 6 t/yr 2003. Although yield with broader soil erosion river basin, riverine discharge shows a strong decreasing trend late 1960s 2003, likely due dam construction. Consequently, growth wetlands at delta front...
The 1951–2004 time series of annual sediment supply from the Yangtze were analyzed using wavelet method. Coastal bathymetric data processed Arc‐GIS software. A typical intertidal flat was measured May 2002 to August 2005 for comparison bed levels before and after Three Gorges Dam (TGD). There is a significant decreasing trend in riverine since late 1960s, which attributed mainly dam constructions. TGD reduced load to147 mt/yr 2004, only 35% average. In response this drastic decrease, deltaic...
To examine the influence of deposition and erosion within main river channel large lakes on sediment delivery to estuary at mouth Yangtze River, we established budgets from time series data for 1956–2004 annual load gauged 24 stations estimated ungauged areas. Ungauged areas supplied approximately 17% total estuary, while an average 34% is stored in complex. Prior operation Three Gorges Dam (TGD) 2003, 88% occurred a 700‐km section immediately downstream outlet area, including linked lake....
Abstract Based on data from river gauging stations, the multi-year variations in suspended sediment flux (SSF) China's nine major rivers to sea were examined. The decadal SSF decreased by 70.2%: 1.81 Gt/year for 1954–1963 0.54 1996–2005. decrease was more dramatic arid northern region than wet southern region; north south, 84% Yellow River, 42% Yangtze and 22% Pearl River. Dam construction principal cause SSF. At present, approximately 2 of is trapped reservoirs within basins. Reduced...
To evaluate the response of river discharge to anthropogenic impacts and climate variability over Industrial Period, we reconstructed past series monthly from three gauges on main Yangtze by means regression (making use cross correlation among gauges) analyzed integrated data (the observed with missing values filled values) for period 1865–2008 in relation human activities variability. The correlative coefficients between predicted discharges at stations gauging are R 2 = 0.90–0.96 ( n...
Abstract Uninterrupted records of annual discharge from the Yangtze River to sea (at Datong Hydrographical Station) began in 1950s. This series shows no significant trend. However, at Hankou, a station upstream Datong, discharges have been observed since 1865 almost without gaps. The and Hankou were found be closely correlated. Based on regression equation, missing estimated time 2004 was established. Although has varied greatly, it decreasing trendline revealed an 8.2% decrease 2004....
Abstract. The surface erosion area in the Yangtze River basin increased from 364×103 km2 1950s to 707×103 2001 due a great increase population. Based on regression relationship between and population, was predicted be about 280×103 at beginning of 20th century. sediment yield, which by 30% during first six decades century, closely related this river basin. annual suspended flux into estuary 395×106 t a-1 gradually an average 509×106 1960s. accelerated 1960s rapid population land use...
Abstract. Lake Dongting, the second largest freshwater lake in China and located middle reaches of River Yangtze catchment, was formed at beginning Holocene period by sea level rise has varied size with changes local weather patterns. The sedimentation rate Dongting during is about 50×106 m3 yr-1, or 80×106 t yr-1 (a sand bulk density 1.6×103 kg m-3), given sediment deposition as 10 mm average 5000 km2. By comparing import export, it estimated that 110.6×106 from 1956 to 2003. Siltation...
This paper examined the sediment gain and loss in river mouth reach of Yangtze River by considering load from local tributaries, erosion/accretion course, impacts sand mining, water extraction. A quantitative estimation contribution to was conducted before after impoundment Three Gorges Dam (TGD) 2003. The results showed that a net 1.78 million ton/yr (Mt/yr) occurred 1965 2002 study area. this discharge into sea is not as high what expected TGD. With TGD, channel deposition (29.90 Mt/yr)...
The information diffusion model is widely used in natural disaster risk assessment because of its operationalization, low data requirements and clear significance the evaluation results. However, commonly normal based on an average distance assumption, widow with h directly affected by sample size extreme values, especially when more than 11, which may lead to unstable results diffusion, typical uncertainty. Considering influence whole samples points, incorporating connection number method,...
