Numerical simulation of groundwater and early warnings from the simulated dynamic evolution trend in the plain area of Shenyang, Liaoning Province (P.R. China)
roundwater table Groundwater exploitation
2018/3/23
Groundwater level is the most direct factor reflecting whether groundwater is in a virtuous cycle. It is the most important benchmark for deciding whether a balance can be struck between groundwater d...
Estimation of evapotranspiration in the Mu Us Sandland of China
Estimation evapotranspiration Mu Us Sandland
2010/4/7
Evapotranspiration (ET) was estimated from 1981–2005 over Wushen County located in the Mu Us Sandland, China, by applying the Advection-Aridity model, which is based on the complementary relationship ...
HYDROCHEMISTRY AND MAPPING OF THE GROUNDWATER CONTAMINATION INDEX IN CHANGCHUN CITY, CHINA
HYDROCHEMISTRY CHANGCHUN CITY GROUNDWATER CONTAMINATION INDEX
2009/10/13
Groundwater quality is changing in Changchun City. The Ca-HCO3 or Ca-Cl facies type tends to be influenced by release of anthropogenic nitrate, calcium, sulfide, and chloride. A scatter analysis shows...
INVERSE MODELING TO IDENTIFY NONPOINT SOURCE POLLUTION USING A NEURAL NETWORK, TAIHU LAKE WATERSHED, CHINA
NONPOINT SOURCE POLLUTION INVERSE MODELING NEURAL NETWORK TAIHU LAKE WATERSHED
2009/10/13
Various studies have been carried out for the evaluation of non-point source pollution using physically-based distributed hydrological and water quality models. A number of modeling interactions have ...

Geographic Information Systems Hydrologic modeling inland watersheds
2009/10/12
Geographic Information Systems (GIS) have been recognized as a powerful means to integrate and analyze data from various sources in the context of comprehensive watershed management. Hydrologic modeli...
Seasonal and diurnal variations in moisture, heat and CO2 fluxes over a typical steppe prairie in Inner Mongolia, China
moisture CO2 fluxes heat
2009/7/22
In order to examine energy partitioning and CO2 exchange over a steppe prairie in Inner Mongolia, China, fluxes of moisture, heat and CO2 in the surface layer from June 2007 through June 2008 were cal...
Quantifying the effect of land use and land cover changes on green water and blue water in northern part of China
land use green water land cover changes blue water
2009/7/22
Changes in land use and land cover (LULC) have been occurring at an accelerated pace in northern parts of China. These changes are significantly impacting the hydrology of these parts, such as Laohahe...
Rapid channel incision of the lower Pearl River (China) since the 1990s as a consequence of sediment depletion

It is widely recognized that food consumption patterns significantly impact water requirements. The aim of this paper is to quantify how food consumption patterns influence water requirements in China...
Detecting changes in extreme precipitation and extreme streamflow in the Dongjiang River Basin in southern China
extreme streamflow Dongjiang River Basin southern China
2009/4/28
Extreme hydro-meteorological events have become the focus of more and more studies in the last decade. Due to the complexity of the spatial pattern of changes in precipitation processes, it is still h...
One expected consequence of global warming is the increase in evaporation. However, lots of observations show that the rate of evaporation from open pans of water has been steadily decreasing all over...
