However, washing it sewage from and where the tap water comes discharged from the kitchen or bathroom goes to. As symbolized by urbanization, the load of human activities excessively impacts on the nature of the river basin and today, it is extremely important to improve the space and basins. ion to rehabilitate rivers water amenities, and natural restorat for river, water quality, For this purpose, it is important to reduce the various burdens on rivers. However, such activities are lim- ited. Consequently, we should draw out the regenerating power of the river provided by nature. We should also think of a sustainable river restoration approaches. Moreover, those who are concerned should cooperate of the entire globe. cope with these problems for the benefit with each other to For the human race to survive for a long time on earth, our entire activities should be changed to be cyclical and coexistent with nature as soon as possible to reduce the load on rivers.

It is calm in its normal state, but the width of the water sur- face sometimes becomes extremely small and at other times, the flow is even disrupted due to water shortage. In the meantime, once a river is swollen, the streamflow will cut away the river bed and riverbanks and carry away riverside living organisms. Sediment flowing from upstream heaps up, and the form of the river may change. In this way, rivers change at various time points naturally or artificially to its present form. Human beings and organisms in a river adapt themselves to the nature of the river and how it operates in live. order When to thinking of the river environment, it is important to understand the characteristics of the stream- flow of the river.
