Restore our Rivers and Streams

If we try to look at our rivers and streams, hence we can say that it really needed restoration. Almost of our rivers today lost its beauty and we cannot see living creatures enjoying swimming in its rich and bountiful water due to abuse of nature.

The restoration of rivers and streams has attracted increased interest and funding in recent years, as a result of legal requirements to mitigate damage to important habitats and as a positive avenue through which citizens can take steps to improve their environment.  River restoration is undertaken for a variety of goals, including restoration or enhancement of aquatic and riparian habitat, provision of functional recreational corridors in urban areas, and to improve water quality.  River restoration activities include recreation of meander bends on straightened channels, modification of channel geometry to create habitat for fish, planting banks with riparian vegetation, and creating open channels from streams formerly encased in underground culverts.  Ironically, the attractiveness of river restoration today is possible only following the elimination of point sources of water pollution effected in recent decades (in the US as a result of the Clean Water Act).

River and stream restoration does not constitute a separate field or a unique bag-of-tricks to be used on degraded rivers.  Rather, restoration involves the intelligent and integrated application of knowledge and techniques from other fields, such as ecology, hydrology, and geomorphology.  While the goals of restoration projects are often ecological in nature, the hydrology and geomorphology of the channel commonly determines whether the project ultimately achieves its objectives.  (As noted by the National Research Council in its 1992 report Restoration of Aquatic Ecosystems, many river restoration projects have failed because they were based more on 'folklore' than sound hydrologic and geomorphic analyses.)   Thus, the application of sound geomorphic analysis is prerequisite to successful restoration planning and design.

Each of us need to contribute for rivers and streams restoration in order to bring back the environment which we have before for the future of our children. Preserve nature, restore the rivers and streams.
