A nonlinear mathematical model for the optimal operation of a parallel pumping station group was established with objective minimizing costs considering target quantity water extraction and flow unevenness between units each as constraints. The original is decomposed into several sub-models single multi-objective optimization lifting capacity pump coordinating variable. This constructed solved ...

Ecological compensation has recently gained significant attention as an economic incentive promoting natural resource management. However, there remain several challenges to its application. A key issue is the lack of a method clearly define standard ecological compensation. This study established accounting methodology for water-receiving area in inter-basin water diversion China. Beijing, maj...

The Yangtze River Basin experiences frequent extreme heatwaves and prolonged droughts, resulting in a tight supply demand balance of electricity negatively impacting socioeconomic production. Meanwhile, ongoing inter-basin water diversion projects are planned that will divert approximately 25.263 billion cubic meters from the annually, which may further affect power region. In this study, CLHMS...

the purpose of this study is to extend the existing knowledge of inter-firm knowledge transfer research and provide a deeper understanding of knowledge transfer practice in an alliance context, as well as the reasons for such a practice. this study reports on relevant results derived from semi-structured interviews with 16 top managers in a chinese international joint venture (ijv) formed by tw...

The water of the Colorado River of the southwestern United States (U.S.) is presently used beyond its reliable supply, and the flow of this river is forecast to decrease significantly due to climate change. A recent interim report of the Colorado River Basin Water Supply and Demand Study is the first acknowledgment of these facts by U.S. federal water managers. In light of this new stance, we e...

One of the main manifestations of climate change will be increased rainfall variability. How to deal with this in agriculture will be a major societal challenge. In this paper we explore flexibility in land use, through deliberate seasonal adjustments in cropped area, as a specific strategy for coping with rainfall variability. Such adjustments are not incorporated in hydro-meteorological crop ...

Unconventional shale-gas plays are formed by fine-grained organic-rich shales of tight-porosity and ultralow permeability which act as the source, seal, and the reservoir rock. The shale-as-reservoir has its beginnings in 1820 but commercial shale-gas wells were drilled in 1990s in Mississippian Barnett Shale of USA by Mitchell Energy after prolonged (about 17 years) experimentations and advanc...

Article history: Received 23 November 2016 Accepted 19 March 2017 Available online 6 April 2017 Since the late 1990s, the central basin of Lake Erie has reputedly experienced an increase in the frequency and severity of hypoxic events. However, total phosphorus (TP) loading, in-lake TP concentrations, chlorophyll a (Chl a), and sediment oxygen demand (SOD) have all declined in the central basin...

We investigated the Rossby Centre regional climate model, RCA3, and its ability to reproduce the water budget of the Baltic Sea drainage basin during the period from 1979 to 2002. The model was forced on its lateral boundaries with European Centre for MediumRange Weather Forecasts Re-Analysis data, ERA40. Simulated long-term means and inter-annual variability were compared with observational re...
