A method and system for observing the daily variation law of vertical water temperature in a cross-section of an ultra-wide water area

Abstract

The invention discloses a method and system for observing the daily variation law of vertical water temperature in a cross-section of an ultra-wide water area. Observe the vertical line and its measuring point layout, as well as observe the time distribution law and spatial distribution law of the vertical water temperature in the cross-section of the ultra-wide water area; the observation system includes the hydropower dam and the upstream left bank of the hydropower dam located on both sides of the hydropower dam And the upstream right bank of the hydropower station dam, several observation vertical lines are arranged above the hydropower station dam between the upstream left bank of the hydropower station dam and the upstream right bank of the hydropower station dam, and water temperature observation instruments are arranged at the observation points of each vertical line. By adopting the observation method and the observation system described in the present invention, the systemicity, representativeness and reliability of the observation results of the intraday water temperature variation law of the cross-section of the ultra-wide water body are ensured.

Description

technical field [0001] The invention belongs to the technical field of hydrological observation, and in particular relates to a method and system for observing the daily variation law of vertical water temperature in an ultra-wide water area cross-section. Background technique [0002] At present, there are few systematic observation and research work on the distribution of water temperature changes in oceans, rivers, lakes, reservoirs and other water bodies in my country, especially for the water temperature changes, distribution laws and related effects of the ultra-wide waters in oceans, rivers, lakes, reservoirs and other water bodies There are fewer observations and researches, the technical methods and requirements for the observation of the temporal and spatial distribution of water temperature in ultra-wide waters lack the effective unification of relevant guidelines or norms, and the quality of the observation results of water temperature and temporal and spatial dist...

Problems solved by technology

[0002] At present, there are few systematic observation and research work on the distribution of water temperature changes in oceans, rivers, lakes, reservoirs and other water bodies in my country, especially for the water temperature changes, distribution laws and related effects of the ultra-wide waters in oceans, rivers, lakes, reservoirs and other water bodies There are fewer observations and researches, the technical methods and requirements for the observation of the temporal and spatial distribution of water temperature in ultra-wide waters lack the effective unification of relevant guidelines or norms, and the quality of the observation results of water temperature and temporal and spatial distribution in ultra-wide waters is generally systematic, representative, and reliable. Therefore, it is of little reference significance to improve the mathematical model research on water temperature change laws of oceans, rivers, lakes, reservoirs and other water bodies in my country, the improvement of empirical formulas and the development of calculation software.
