Major water-body type

Figure 6.13Nearest major water-body type relative to distance from city center.

Major is in a global rather than regional context. Three cities (Bangkok, Stockholm,

Cuttack) are near two major water-body types. 10 km = 6.2 mi. See Figure 6.2 for city

information.

body is small, a major flood hazard for the metro area is likely. Also nearby
coastal or riverside recreation sites are likely to be degraded and polluted, espe-
cially close to and downriver of the city. Fish migration on the river is apt to be
blocked by urban water pollution.

[W10]Aquarter of the regions has no major water body present (i.e., within 100 km of city
center), another quarter has the nearest major water body 15--100 km distant(Figure6.13).

Aquifers are likely to be especially important in these regions, and require
nearly continuous natural vegetation cover to protect water quality. These
regions are likely to have little flood hazard, less-polluted recreation sites serving
fewer people, and a less-convenient shipping/ferry port. A strip of development
between city and port, which forms a barrier to regional wildlife movement, is
apt to be present. Major breaks in the strip development should be established
and maintained for regional wildlife movement.
