This study proposed seven priority steps as a procedure for making a master plan for
restoring destroyed aquatic system with biological consideration.Step 1 is to set up the basic
concept of restoration by considering the characteristics of the target river. The objective of Step
2 is to survey and evaluate the channel form changes of the target river. Step 3 is to estimate the
natural environment including ecological habitat and the extent of damage. Step 4 is to analysis
the change of biota, endangered species, dominant species, and select the restoring species.
Step 5 is to establish the restoring plan including selection and restoration of ecologically
functional area, security of biodiversity. Step 6 is to select the applied facilities such as wetland,
fish habitat block, fishway. Finally, Step 7 is to establish the master plan of restoring plan through
the consultation and consensus of various stakeholders.
