Water quality is one of the elements of hydrology, and water quality can only be organically integrated with water quantity, sediment, river topography and water ecology to form water conservancy monitoring results, in order to give full play to the element water level monitoring system to a certain extent, and truly meet the requirements of modernization of hydrological monitoring.

It is very important to strengthen hydrology and water quality monitoring capacity!

Under the current market requirements, only the deep integration of traditional hydrology and water quality to achieve the content and quality of water sources can promote the further development of modern hydrology tests. The simultaneous combination of hydrology and water quality can form the material flux results of cross section, indicating the circulation path of carbon, nitrogen and phosphorus resources. In addition, the combination of water quantity and water ecology can form the relationship between water quantity and biological habitat/biodiversity impact, thus forming the sediment fingerprint spectrum, which is used to estimate the sources of soil erosion and non-point sources of pollution. There is also the combination of water quality and river topography, which will form a coupling model of river and lake water dynamic and water quality, which provides a theoretical basis for the calculation of self-purification capacity of important rivers and lakes and the calculation of water resources carrying capacity. Nowadays, isolated water quality monitoring can no longer meet the requirements of the development of The Times, so multiple integration is the king!
