Joint assessment of groundwater-surface water resources can help develop sustainable regional water management plans for intensive agriculture. In this study, we estimated allowable groundwater and surface water quantities using a water balance model, WetSpass-GMS, for the Sanjiang Plain (10.9 × 104 km2), one of the most important grain production bases in China. We then applied a double contro...

Abstract Water scarcity threatens people in various regions, and has predominantly been studied from a water quantity perspective only. Here we show that global is driven by both quality issues, quantify expansions clean technologies (i.e. desalination treated wastewater reuse) to ‘reduce the number of suffering scarcity’ as urgently required UN’s Sustainable Development Goal 6. Including tempe...

In this paper, surface and piezoelectric effects on the vibration behavior of nanowires (NWs) are investigated by using a Timoshenko beam model. The electric field equations and the governing equations of motion for the piezoelectric NWs are derived with the consideration of surface effects. By the exact solution of the governing equations, an expression for the natural frequencies of NWs with ...

drought as a natural but temporary imbalance of water availability is the interaction between natural environment and human life resulting in diminished water resources availability and reduced carrying capacity of the ecosystems. drought indices are essential elements for an efficient drought monitoring system. these indices make the transforming information of climatic anomalies easier and al...

The role of the river in global water cycles and the modeling of horizontal water transport by rivers in the global scale are discussed. Due to the consolidation of various hydrological information about the planet, it is possible now to monitor and simulate the quantity of water carried by rivers. Land surface models, that were developed originally for giving the boundary condition of the atmo...

Surface water samples of baseflow were collected from 20 headwater sub-watersheds which were classified into three types of watersheds (natural, urban and agricultural) in the flood, dry and transition seasons during three consecutive years (2010-2012) within a coastal watershed of Southeast China. Integrating spatial statistics with multivariate statistical techniques, river water quality vari...
