A Nationwide Analysis of Water Scarcity and Cloud Seeding Demand Levels From Analyzing Water Utilization Data, Agricultural Drought Maps, and Local Conditions in China Mainland

open access: yesEarth and Space Science, Volume 8, Issue 6, June 2021., 2021
Abstract China has lots of funds, materials, and human resources in cloud seeding operations to help with water shortage problems across the country. But there is little guide about when and where the operations would obtain better benefits. To fill this gap, the modified Water Utilization Level (WUL) map of China mainland was plotted with the ...

1-D movable bed numerical forecast model of salinity of the Qiantang River estuarine reach and its application

open access: yesShui kexue jinzhan, 2015
The Qiantang River estuary is an alluvial estuary with strong tidal bore,high sediment concentration and easy changeable riverbed. The interaction between tide and fluvial feedback has great effects on saltwater intrusion.

Influence of Tide and Runoff on Saltwater Intrusion in the Qiantang River Estuary, China

open access: yesIOP Conference Series: Earth and Environmental Science, 2021
Abstract Qiantang River Estuary, as one of main fresh water resources for urban zone, has been threatened by salt water intrusion. Due to the combined influence of tide and runoff, the mechanism of saltwater intrusion is extremely complex.

Table_1_Spatial and temporal distribution of macrobenthos communities and their relationship with secondary front in Hangzhou Bay.docx [PDF]

open access: yes, 2022
Water quality in Hangzhou Bay is inferior (grade 5) because of discharged from Yangtze River and Qiantang River, and from factories around the bay. This study analyzed relationships between the environment and macrobenthic communities at 44 stations ...

Interaction of flow-riverbed and its effects on saltwater intrusion in Qiantang River estuary

open access: yesShui kexue jinzhan, 2015
Based on the long term hydrological and bathymetric analysis,the morphological evolution in the estuary features the significantly large riverbed change,that is,the great erosion in runoff-dominated periods and the great sedimentation in tide-dominated ...

A preliminary study on seasonal variations of sediment concentrations in the inner Qiantang Estuary

open access: yesIOP Conference Series: Earth and Environmental Science, 2020
Abstract The Qiantang Estuary is characterized by high suspended sediment concentrations, due to the world-famous tidal bore. In this study, continuous sediment concentrations has been observed in the inner Qiantang Estuary in April, June, September and November of 2018, by fixing an OBS on a floating platform.

Evolution and genetics of bighead and silver carps: Native population conservation versus invasive species control

open access: yesEvolutionary Applications, Volume 13, Issue 6, Page 1351-1362, July 2020., 2020
Abstract Bighead carp (Hypophthalmichthys nobilis) and silver carp (H. molitrix), collectively called bigheaded carps, are cyprinids native mainly to China and have been introduced to over 70 countries. Paleontological and molecular phylogenetic analyses demonstrate bighead and silver carps originated from the Yangtze‐Huanghe River basins and modern ...
