Mapping Water Vulnerability of the Yangtze River Basin: 1994–2013

Abstract

A holistic understanding of the magnitude and long-term trend of water vulnerability is essential for making management decisions in a given river basin. Existing procedures to assess the spatiotemporal dynamic of water vulnerability in complex mega-scale river basins are inadequate; a new method named ensemble hydrologic assessment was proposed in this study, which allows collection of data and knowledge about many aspects of water resources to be synthesized in a useful way for vulnerability assessment. The objective of this study is to illustrate the practical utility of such an integrated approach in examining water vulnerability in the Yangtze River Basin. Overall, the results demonstrated that the ensemble hydrologic assessment model could largely explain the spatiotemporal evolution of water vulnerability. This paper improves understanding of the status and trends of water resources in the Yangtze River Basin.

Identifying multivariate controls of pan evaporation variations in subregions of Yangtze River Basin using multiple wavelet coherence

“…Meanwhile, it is also a typical subtropical intensive agricultural production region of the world, where the main crop production system is rice, vegetables and oil crops (Guo et al, 2021). The YRB has rich and diverse vegetation types, mainly composed of forests, agricultural areas and grasslands (Sun et al, 2016). However, due to the vast territory, complex topography, uneven distribution of precipitation (Li et al, 2021), great east–west variation of annual average temperature (Yue et al, 2021), the YRB is also a frequent area of drought and waterlogging disasters in China.…”

Development of a Field Scale SWAT+ Modeling Framework for the Contiguous U.S.

“…This model is in use to guide the region's policy makers on climate change effects on the river and downstream lagoon environment, as well as possible nutrient reduction measures. Several of the very large river basins in China have also been simulated using SWAT including the lower Mekong (Mohammed et al 2018), Yangtze (Sun et al 2016), and Yellow rivers (Yu et al 2017) with varying levels of spatial granularity.…”
