  • Attaining Sustainable Water Resource Utilization in Lake Basins Using Progressive Operational Scenario Analysis
    Water Resources Management, 2020
    Co-Authors: Jiayu Peng, Binghui Zheng, Zhaosheng Chu, Xing Wang
    Abstract:

    Abstract There is a severe conflict between water resource exploitation and protection of the aquatic environment of lakes with rapid urbanization. Sustainable water resource utilization is urgent for sustainable development. The present study introduced a progressive Operational Scenario analysis (POSA) method for water resource regulation in lake basins. The application processes of POSA in Dianchi Lake, Erhai Lake and Fuxian Lake were described in detail. The effectiveness of the POSA method and Scenario analysis method in achieving sustainable water resource utilization were compared and analysed, and the improvement in the efficiency of water resource utilization in lake basins due to the two methods was discussed. The results showed that implementation of POSA can effectively achieve sustainable water resource utilization in Dianchi Lake, Erhai Lake and Fuxian Lake and reduce the aquatic environmental pressure. Compared with business-as-usual, this method reduced the water use efficiency indicators of Dianchi Lake, Erhai Lake and Fuxian Lake by 2%–8%, 1%–25% and 8%–35%, respectively, and the water environmental pressure in Dianchi Lake, Erhai Lake and Fuxian Lake decreased by 28.51%, 29.70% and 69.39%, respectively. POSA has been proven to be an excellent tool for managing the aquatic environments and regulating water resources in lake basins.

  • A dualistic water cycle system dynamic model for sustainable water resource management through progressive Operational Scenario analysis
    Environmental Science and Pollution Research, 2019
    Co-Authors: Jiayu Peng, Yimei Cao, Shaoyong Lu, Minghao Wang, Xiaozhen Hu, Xing Wang, Binghui Zheng
    Abstract:

    A reliable system simulation of the reciprocal mechanism between water resource utilization and dualistic water cycle is essential to the basin water resource sustainability management. In this study, a system dynamic model was built to simulate the water cycle change and lake water environmental pressure under the influence of water resources utilization, and the procedure of a progressive Operational Scenario analysis of how to relieve water environment pressure was illustrated. Dianchi Lake, which is the sixth largest and the most severely polluted freshwater lake in China, was employed as a case study to demonstrate the applicability of the model. The change of runoff components and pollution load of total nitrogen from 2000 to 2030 were discussed. Also, the sustainable water resource management was ultimately realized in the planning period through three progressive levels of water resource regulation Scenarios. Compared with business-as-usual Scenario, the TN pollution load into lake and total water demand decrease by 27.1 and 27.3%, and the domestic water use, industry water use, tertiary industry water use, and irrigation decrease 9.0, 16.8, 29.5, and 30% in the Scenario 3.

  • MESAS - Operational Scenario Modelling Supporting Unmanned Autonomous Systems Concept Development
    Modelling and Simulation for Autonomous Systems, 2018
    Co-Authors: Marco Biagini, Fabio Corona, Josef Casar
    Abstract:

    There exists a connection between a growing number of Unmanned Autonomous Systems (UAxS) and a number of possible security challenges. The likelihood that swarms of UAxS will be employed in high populated mega-city environments in the long and mid-term exacerbates these future challenges. The problem is two-fold: UAxS are likely to be used as additional capability for friendly forces, but they are also to be considered as possible threat. The challenges that an autonomous system poses depend not only on their physical vulnerability or the security of the networks and data, but also on the interaction with traditional troops and operating procedures to be followed, their levels of autonomy and Command and Control (C2) chain behind their employment. An extensive experimentation is necessary to address some of these challenges in a Concept Development and Experimentation (CD&E) process aimed to envision solutions. Modelling and Simulation (M&S) tools and architecture are essential to speed up this process in a cost effective way. This paper presents how the development of a particular air Operational Scenario in an urban environment, according to the Simulation Interoperability Standard Organization (SISO) guide using M&S tools, can support the capability development process for future UAxS as well as their countermeasures.
