Method and system for observing temperature increase effect of afflux of tributary along riverway under reservoir dam

Abstract

The invention discloses a method and system for observing a temperature increase effect of the afflux of a tributary along a riverway under a reservoir dam. The method comprises arranging under-dam observation points and a tributary observation group, arranging a water temperature sensor, sending and recording water temperature data, analyzing data, and drawing an observation graph. The system comprises under-dam observation points and a tributary observation group. The under-dam observation points are power generation tail water temperature observation points arranged at the downstream of each reservoir dam distributed along a main stream. The tributary observation group comprises a tributary observation point A, a tributary observation point B, and a tributary observation point C arranged on the junction of the tributary and the main stream. The tributary observation point A is arranged on the main stream and is located at the upstream of the junction. The tributary observation point B is arranged on the tributary and is located at the upstream of the junction. The tributary observation point C is arranged on the main stream and is located at the downstream of the junction. The method and the system fill in a blank in observation and research of water temperature change rule distribution cases along the riverways under high dams and large reservoir dams.

Description

technical field [0001] The invention relates to the technical field of river hydrological observation, in particular to an observation method and an observation system for the temperature increase effect of tributary confluence along a river channel under a reservoir dam. Background technique [0002] At present, there are few observations and studies on the distribution of water temperature changes along the rivers under high dams and large reservoirs in my country, especially on the water temperature changes and related effects before and after the influence of tributaries along the rivers. The technical methods and requirements for the observation of the warming effect of the tributary confluence along the river under the dam lack the effective unity of relevant guidelines or specifications, and the quality of the observation results of the tributary confluence along the river channel is generally systematic, representative, and reliable. It is of little reference significa...

Problems solved by technology

[0002] At present, there are few observations and studies on the distribution of water temperature changes along the rivers under high dams and large reservoirs in my country, especially on the water temperature changes and related effects before and after the influence of tributaries along the rivers. The technical methods and requirements for the observation of the warming effect of the tributary confluence along the river under the dam lack the effective unity of relevant guidelines or specifications, and the quality of the observation results of the tributary confluence along the river channel is generally systematic, representative, and reliable. It is of little reference significance to improve the research on the mathematical model of the change law of river water temperature in our country, the improvement of empirical formulas and the development of calculation software.
