Rivers serve three main functional roles: flood control, water utilization,
and environmental. Flood control refers to the prevention of flood damage
and water utilization describes the use of water for waterworks, agricultural
use, and ship-based transportation. The environmental function of rivers
emerges from a recognition of rivers as valuable riparian space in terms
of helping to forge a unique relationship between residents and the water
in their midst. In a broad sense, river projects are defined by respect
for and adherence to these functions. |
