ABSTRACT Water level adjustment downstream of dams significantly impacts river regimes and flood control. However, due to constant strong scouring, our quantitative understanding the characteristics water variations their causes in Chenglingji–Jiujiang Reach Yangtze River remains limited. Here, we analyzed change trend via Mann–Kendall method geomorphic resistance using 406 cross-sectional profiles as well data on discharge levels from 1991 2022. Results showed that critical conversion...
Abstract In the Yangtze River, Three Gorges Dam (TGD) has altered flow‐sediment regimes, resulting in channel degradation and bed surface coarsening, which have been reported recent years. However, there no systematic study on impacts of TGD downstream gravel–sand transition (GST). Based detailed field observations numerical modelling, this fills gap reveals significant adjustments GST leading causes. The results show that after operation began, migrated 49.5 km during 2003–2010 due to a...
Large differences in projected future annual precipitation increases North America exists across 27 CMIP6 models under four emission scenarios. These partly arise from weak representations of land-atmosphere interactions. Here we demonstrate an emergent constraint relationship between growth rates and historical temperature. The original projections show 0.49% (SSP126), 0.98% (SSP245), 1.45% (SSP370) 1.92% (SSP585) per decade. Combining observed warming trends, the constrained results that...
Abstract Many studies have focused on analyzing variation characteristics of the watershed resilience based different indicators, while few efforts been made to quantificationally evaluate contributions climatic and anthropogenic factors varied resilience. In this study, we investigate changes in seasonal runoff entire Yangtze River basin during 1961–2014 by using a convex model indicator (Pi). The MIKE 11HD regression method were adopted further differentiate effects climate variations...
Abstract Despite abundant studies on gravel‐sand transitions (GSTs), GST origin and migration in large alluvial channels characterized by significant variations width, numerous tributary (or distributary) streams, frequent human disturbances remain difficult to explain. Here, we take the Yangtze River as an example use field observations numerical modeling make progress toward addressing migration. The results show that exhibits a non‐abrupt approximately 60 km long. Within adjacent area,...
Abstract Understanding and accurately predicting how the sensitivity of terrestrial vegetation productivity to rising atmospheric CO 2 concentration ( β ) is crucial for assessing carbon sink dynamics. However, temporal characteristics driving mechanisms remain uncertain. Here, observational CMIP6 modeling evidence suggest a decreasing trend in at Northern Middle High Latitudes during historical period 1982–2015 (−0.082 ± 0.005% 100 ppm −1 year ). This projected persist until end 21st...
Collusion problem is very severe in bidding activities China. It does great harm to engineering quality, market mechanism construction and country benefit. the which has be resolved consummating In this paper, We analyze based on game theory. There are two kinds of collusion, collusion between tenderer tenderee, among tenderers. just latter. Firstly we make an once analysis. And then a multiple games analysis given. On foundation result, corresponding measures reduce behaviors proposed.
Forecasting has become an essential part of modern thought, but the practical limitations still are manifold. We addressed future rates change by comparing models that take into account time, and focus more on space. Cox regression confirmed linear can be safely assumed in short-term. Spatially explicit Poisson regression, provided a ceiling value for number deforestation spots. With several observed estimated rates, it was decided to forecast using robust assumptions. A Markov-chain...
