Embodiment Construction
[0046] This embodiment is a flood rolling forecast method for automatic calibration, which specifically includes the following steps:
[0047] Obtain the forecast station determined by the user in the simulation area, and determine the topological relationship between the forecast station and its upstream and downstream stations and river sections according to the spatial topological relationship of the river in the simulation area;
[0048] Extract the measured water level or flow data along the river in the simulation area at the time of simulation calculation, and interpolate the measured water level or flow data along the river according to the spatial topological relationship of the river and the profile stability process line of the river to obtain more accurate initial conditions , and input the interpolated data into the verified rolling flood forecast model for the initial startup calculation of the model;
[0049] Output the forecast water level and flow data of the ...
