Question
For the following Vertical Profiles of Temperature Graphs, Explain what happens in each graph? (in other words translate the graphs into a short answer essay)

In spring season, Temperature and Dissolved oxygen level is constant. It maintain the oxygen level and it does not involve in self purification process.
It required high level water treatment process. Based on depth treatment process is not varry.
In mid summer season, Temperature will increase also it increase the dissolvedoxygen level. It increase the self purification capacity of the river.
In top layer treatment process is low level
But After 13 m, DO level is zero. ie. Completely unaerobic condition. Then treatment is not easy.
