Abstract: The comprehensive renovation project model of lower reaches of Ganjiang River was built in outdoor environment and characterized as multi-stage bifurcation, so it puts forward higher requirements for the measurement-control system in terms of operation reliability and lightning protection. On the basis of field situation analysis, a set of more advanced design scheme for the model measurement-control system was presented. The measurement-control system is composed of water supplying system of flat water tower, flow control system, water level and flow velocity measurement system, tail gate control system, lightning protection and grounding system, topographic survey system and so on. This paper briefly introduces the working principle, design scheme and application situation of each sub-system. The system uses modern network technology and high performance automatic measuring instruments, which can realize real-time data acquisition, control and data processing of various parameters in the model test. The test results show that the measurement-control system can meet the requirement of the model test of comprehensive renovation project of lower reaches of Ganjiang River.

Key words: lightning protection, geography survey, measurement-control system, hydraulic model of lower reaches of Ganjiang River
