Introduction

Interpretation of the core content of the standard

Monitoring type	Key indicators	Technical methods	Accuracy requirements
Battery lake monitoring	Reservoir capacity change rate, dam breach flow	3D laser scanning/UAV aerial survey	Plane error≤0.1m
Breach flood diversion	Gate width, maximum flow	Electromagnetic current meter + hydraulic formula	Flow error≤15%
Ice dam disasters	Ice dam volume, backwater length	Aerial photography + volume estimation method	Volume error ≤ 20%

Technical innovation points

1. Multi-source data fusion: For the first time, it clearly requires the coordinated application standards of new technologies such as GNSS, remote sensing, and drones with traditional hydrological monitoring methods.

2. Dynamic precision control: Differentiated precision management is implemented according to the emergency response level, and in special circumstances, it is allowed to be relaxed to 1.5 times that of conventional monitoring.

Implementation case analysis

In the 2020 Yangtze River Basin barrier lake incident, the cruise-type ADCP specified in this standard was used in conjunction with drone aerial survey to complete the reservoir capacity curve drawing within 24 hours, which is 300% more efficient than traditional methods.

Equipment configuration requirements

Emergency monitoring equipment is divided into three levels of configuration: basic (radio current meter + portable water level meter), enhanced (3D laser scanning + Doppler radar), professional (unmanned survey ship + multi-beam system).
