Tank and method for multi-factor coupling simulation test based on dynamics of estuary and coastal

Abstract

The invention discloses a tank and a method for multi-factor coupling simulation test based on dynamics of estuary and coastal. During simulation test, runoff or tide simulated closed cycle is formed in the same tank body through a two-way current generator which is communicated with a front basin and a rear basin; a closed salt tide upstream simulation cycle is formed in the tank body under cooperation of a salt water reservoir, a fresh water reservoir and a salt water and fresh water separator; a target spectrum is simulated by a wave maker; a blower is used for simulation of the target wind speed; accordingly, simulation test for coupling of wind, wave, runoff and salt tide or simulation test for coupling of wind, wave, tide and salt tide can be performed in the same tank, and requirements for the simulation test of multi-factor coupling based on dynamics of estuary and coastal are met; further, simulation test of coupling of one or at least two of wind, wave, salt tide and runoff can also be performed in the tank body.

Description

technical field [0001] The invention relates to the field of estuary and coast dynamic factor simulation tests, in particular to a water tank for estuary and coast dynamic multi-factor coupling simulation tests and a test method thereof. Background technique [0002] The main factors of estuary and coast dynamics include wind, wave, tidal current, runoff, salt tide, etc. Simulating the effect of multi-factor coupling on estuary salty and fresh water flow is useful for studying the evolution law of estuaries, the operation law of estuary water bodies, and the impact on the ecology and environment of estuaries and coasts. The influence and so on have great guiding significance. [0003] The current test tanks generally can only conduct tests on a single factor. For example, common hydraulic model test tanks can only carry out experiments on runoff acting on hydraulic structures; another example is wave test tanks, which can only carry out wave tests. Therefore, these tests T...

[0003] The current test tanks generally can only conduct experiments on a single factor. For example, common hydraulic model test tanks can only carry out experiments on runoff acting on hydraulic structures; another example is wave test tanks, which can only carry out wave tests. Therefore, these tests The flume can only simulate the single-factor dynamic mechanism; however, the multi-factor coupling mechanism of the estuary and coast is complex, and it is not a simple superposition of the single-factor effects. The deviation of the situation is relatively large, which cannot meet the simulation test requirements of the multi-factor coupling effect of the estuary and coast
