Mountain torrents are the floods to break that rises suddenly and sharply occurred in the gully of mountain area, are usually occurred suddenly after heavy rain.Due to mountain area
The features such as ground and channel gradient are all relatively steep, concentrate so mountain torrents are usually cashed for water, and flow velocity is big, and erosion damage power is strong.But
It is smaller that mountain torrents involve range, usually centered on river, and constantly washes away generation destruction to both sides.When flood occurs, not only
Can destroy by rush of water cities and towns, factory, mine, rural area etc., cause people and animals' injures and deaths, can also destroy house and other job facilities, destroy farming
Object, forest and arable land.The flow velocity of mountain torrents determine its size with energy, therefore accurate monitoring mountain torrents flow velocity, judgement
Mountain torrents scale simultaneously estimates damaging range, so that it is particularly important during the mountain torrents disaster relief to make correct decision.It is big at this stage
Mostly use Doppler profile instrument, ultrasonic measurement instrument and mechanical flow instrument etc. carry out flow rate of liquid measurement, but all price costly,
And ultrasonic measurement instrument and mechanical flow instrument can only measure single-point flow velocity, carry out local measurement, be unable to large area use.Therefore this hair
Bright to propose that a kind of structure is simple, reasonable price can arrange three-dimensional speed measuring device, relatively continuous accurately measurement flood stream along river
Dynamic speed and direction.
