Discussion of 'Multiobjective Optimization of Sensor Placement for Precipitation Station Monitoring Network Design' by Ke Wang, Jia Yang, Yuling Peng, Qianqian Wu, and Chuli Hu

摘要

Monitoring networks and placement of sensors play a vital role in hydrological variable quantification. The design of rainfall and streamflow sensor networks depends to a large extent on the scale of the processes to be monitored and the objectives to address (Loucks et al. 2005). The performance and accuracy of gauge-based areal estimates of rainfall depend on both the number of gauges in the network and on their spatial location and distribution (Volkmann et al. 2010). The authors have presented a novel methodology based on the multiobjective approach to evolve optimized precipitation networks with relevance to spatial location and distribution. The discusser appreciates the effort of the authors to present improved precipitation measurement methodology by identifying monitoring locations for sensor placement in a precipitation monitoring network. This is a noteworthy contribution.
