Measuring method for salt-fresh water proportion in estuary area
The invention discloses a measuring method for a salt-fresh water proportion in an estuary area. The method comprises the following steps that according to an actual water front of the estuary area and a geography condition, a non-structural grid of a height fitting water front is established, and a Sigma grid coordinate is adopted in the vertical direction; based on the grid, an estuary three-dimensional water power-salinity mathematic model is established, calibration verification, frequency lining and typical year selecting are carried out, salinity calculation is carried out, the salt-fresh water proportion of each grid point is obtained, deviation calculation is carried out on the salt-fresh water proportion of each grid point, and a contour map of the salt-fresh water proportion in the estuary area is obtained. By utilizing the mathematic model, based on set grid point collecting data, the calculation is carried out, the salt-fresh water proportion of each grid point can be obtained, a scale map of the salt-fresh water in the estuary area is drawn, accurate measuring of the salt-fresh water proportion of each point in the estuary area is achieved, rapid and accurate requiring can be achieved, and the salt-fresh water proportion conditions of different water areas in the estuary area can be comprehensively reflected. The invention relates to the field of water conservancy projects, in particular to the measuring method of the salt-fresh water proportion in the estuary area.
