Disclosed is a composite hydrological monitoring system, in which a counterweight component and a test component are respectively connected to both opposite ends of a strip and a plurality of sensors are disposed at different vertical positions. Accordingly, the scour depth can be measured by sensing the location of the counterweight component, whereas the water level and/or flow velocity can be determined by signals from the sensors. When the counterweight component moves downward with sinking of the riverbed, the strip would be pulled down and thus causes the test component to present a change in mechanical energy. Accordingly, the sinking depth can be measured by sensing the change of the mechanical energy. Additionally, since the water level variation would cause signal changes of the sensors arranged in a row along a vertical direction, the change of water level can be determined accordingly.

An environment monitoring system is utilized for monitoring an environmental variation status of a riverbed, a lake floor, or a seabed. The environment monitor system includes a wire drawing device configured at a monitoring point for releasing and tightening a transmission wire; a fixing pipe laid between the monitoring point and a structure layer for containing the transmission wire; a plurality of vibration sensing devices respectively configured on the transmission wire for converting sensed vibration energy to a plurality of electric signals and transmitting the plurality of electric signals by the transmission wire; an analyzing device coupled with the wire drawing device and the transmission wire for obtaining a released length of the transmission wire by the wire drawing device and determining the environmental variation status according to the released length and the plurality of electric signals to perform monitoring.
