Similar to light zonation, thermal stratification or thermal zonation is a way of grouping parts of the water body within an aquatic system based on the temperature of different lake layers. The less turbid the water, the more light is able to penetrate, and thus heat is conveyed deeper in the water. [ 17 ]
In the midreaches of a stream or river, where more light is available, there is an increase in the proportion of grazers due to the presence of periphyton. Shredders only make up a small percentage of the total invertebrates due to the lack of coarse organic matter making its way downstream.

The diagram also shows how human water use impacts where water is stored and how it moves. [1] The water cycle (or hydrologic cycle or hydrological cycle) is a biogeochemical cycle that involves the continuous movement of water on, above and below the surface of the Earth. The mass of water on Earth remains fairly constant over time.
One effective solution is to restore streams and riparian habitat. This improves the entire urban watershed, far beyond the riparian channel itself. [10] Wild et al 2011 described the first known online map and database of urban river daylighting projects. [1] [11] Wild et al 2019 published geo-spatial database about all schemes. [12]
