Problems solved by technology

At present, there are mainly two methods for estuary tide forecasting methods: 1. Numerical calculation method, which calculates and forecasts by establishing a mathematical model. The main disadvantage is that the model modeling is complicated, requires high professionalism, is not easy to operate, and the model calculation is time-consuming. , which is not conducive to real-time control; Second, the hydrological statistical method, based on the long-term series of hydrological data for statistical analysis, and then forecasting, its main disadvantage is that it requires a large amount of measured hydrological data for statistics, cumbersome operation and low efficiency
In general, the current estuary tidal range forecasting methods have problems such as cumbersome operation, low efficiency, high computational complexity, low accuracy, and long time consumption, which lead to inability to accurately forecast

Embodiment 1

[0084] A method for rapid forecasting of tidal range in an estuary, comprising the steps of:

[0085] S1. Collect real-time tide level data and average water depth data at the starting point of the estuary;

[0086] S2. Combined with the collected data, fit the relationship curve between the section of the river bed and the distance along the estuary, and construct the tidal range forecast model of the estuary;

[0087] S3. After substituting the collected real-time tidal level data and average water depth data into the estuary tidal range prediction model, calculate and obtain the tidal range prediction value of each section along the estuary, specifically: the obtained along-course index and the collected real-time The tidal level data and average water depth data are substituted into the formula of the estuary tidal range forecasting model for solution, so as to calculate and obtain the tidal range prediction value of each section along the estuary.

[0088] In this embodi...

Embodiment 2

[0143] Taking the Pearl River estuary as an example, the method of Embodiment 1 is used to carry out dynamic forecast control of urban river flood control and drainage.

[0144] Step 1. Real-time tidal level data and average water depth data at the starting point of the estuary. The acquisition device includes a water level gauge, which can store the collected real-time rainfall data in the data memory, and collect the starting points of Lingdingyang, Modaomen and Huangmaohai in the Pearl River estuary. The tidal level, average water depth and other data at the estuary, and the measured tidal range value H at the starting point of the estuary 0 and average water depth data As shown in Table 1 below:

Abstract

The invention discloses an estuary-tidal-range fast prediction method. The estuary-tidal-range fast prediction method includes the steps that 1, real-time tidal level data and average water depth data at starting points of estuaries are collected; 2, the collected data is combined, relation curves between the cross sections of riverbeds and the along-journey distance of the estuaries are fitted, and an estuary-tidal-range prediction model is constructed; 3, the collected real-time tidal level data and the collected average water depth data are substituted into the estuary-tidal-range prediction model to compute and obtain the tidal-range predictive values of all the along-journey cross sections of the estuaries. The estuary-tidal-range fast prediction method is low in computation complexity, high in computational efficiency and prediction accuracy and easy to operate, and can be widely applied to water conservancy industries, and estuary-tidal prediction can be carried out in real time.

Description

technical field [0001] The invention relates to the field of hydrology and water conservancy engineering, in particular to a method for quickly forecasting the tidal range of an estuary. Background technique [0002] Estuary tide forecasting is to forecast the tide level and tidal range of the estuary area, and forecast the tidal range of each section along the estuary. Correct forecasting plays an important role in guaranteeing the production, living and working conditions of the estuary area such as flood control, navigation, and water supply. At present, there are mainly two methods for estuary tide forecasting methods: 1. Numerical calculation method, which calculates and forecasts by establishing a mathematical model. The main disadvantage is that the model modeling is complicated, requires high professionalism, is not easy to operate, and the model calculation is time-consuming. , which is not conducive to real-time control; 2. The hydrological statistical method is ba...
