A tributary is usually a river that flows directly or indirectly into the main stream. In hydrology, it refers to a river that flows into another river (or other water bodies) without directly entering the sea. The river into which the branch flows is called trunk stream or main stream The intersection of two or more rivers is called Confluence Or confluence. The situation opposite to the tributary is called shunt 。 The flow direction of water along the river can be called the left side tributary and the right side tributary. The tributary is opposite to the mainstream. [1] A river that flows directly or indirectly into the main stream. In larger river systems, tributaries are often divided into primary, secondary and tertiary. Direct inflow trunk stream It is called a primary tributary, and it is called a secondary tributary if it flows directly into the primary tributary, and so on. The tributary level and the river level tributary level are in the same water system. The river directly flowing into the main stream is called the primary tributary, and the river directly flowing into the primary tributary is called the primary tributary Secondary tributary , and so on. The order level of the river channel is that the river channel at the top of the river network without further branches in the upstream is called the primary river channel, and the river channel after the convergence of two primary rivers is called the Secondary channel , and so on. Therefore, the higher the level of a tributary, the lower the level of its channel. The ratio of each river channel to the number of higher rivers is called the order bifurcation ratio or river system bifurcation ratio. Generally speaking, the situation with a large proportion is relatively long and narrow and the flow is stable. Tributaries of the Yellow River:
Weihe River It is the most important river in Shaanxi Province Yellow River One of the main tributaries of guanzhong region Main points of Irrigation water source 。 According to the report of Shaanxi Provincial Environmental Protection Department, the Weihe River enters Shaanxi from Gansu Baoji The water quality at that time was of Class II, but the pollution in the whole process below Baoji gradually increased, reaching Tongguan When entering the Yellow River Inferior to Class V water quality , people describe Shaanxi as“ Eight hundred li Qinchuan A thousand miles of pollution ". The main reasons are the waste water of a large number of paper enterprises along the river and the cities and towns domestic sewage Most of them are discharged directly into the river. Weihe River receives more than 600 million tons of wastewater and 270000 tons of chemical oxygen demand every year, almost equal to environmental capacity 4 times.
