Abstract: This paper addresses the need for emergency monitoring and intelligent simulation in response to sudden water pollution events.We established the correlations of sensor performance with time,space,and attributes and constructed a multi-sensor synergetic monitoring model to accomplish the dynamic and collaborative sensing through a network of satellite,UAV(Unmanned Aerial Vehicle),ground and water platforms.We selected Danjiangkou Reservoir as a demonstration area for dynamic network monitoring of sudden water pollution events. Based on the specific observation requirements during the occurrence,dynamic evolution,and later stages of water pollution events,we determined the corresponding platforms and sensors required. Experimental results manifest that the proposed multi-sensor network captures the water pollution monitoring information comprehensively,accurately,and rapidly. Moreover,it provides scientific support for emergency response and treatment of sudden water pollution events.

Key words: sudden water pollution event, dynamic network, stereoscopic monitoring, multiple sensors
