Hydrological Results of Development of Zoological Parks
Large areas, over which most zoological parts are laid out, may either have inherent
water logging problem or may result in such areas after development. Landscape
development and other construction activity effect surface changes which result
in changes in water levels of bodies such as streams, ponds, lakes, reservoirs and
at occasionally of rivers. This is a result of modification of permeabilities,
infiltration rates and runoff volumes and rates. The quantum of change depends
on the intensity of development.
The quantity of surface runoff will be increased typically because of increase in
area of pavements and reduction in vegetative cover from its original situation

By way of storm water conservation zoological parks provide an ideal
situation because of following reasons:
• Large areas for receiving precipitation.
• The relatively dense vegetation particularly lower storey provides for reduced
run-off velocities encouraging infiltrating of water into the aquifer.
• Space availability for first flush collection of storm water and to provide
flow equalization when required.
• Opportunities for trade/collected water for being used for a wide range of
uses having varied quality requirements.
Landscape Development & Water Use
Landscape development is one of the first areas cut back during time
of shortage for at least two reasons.
• It is a visible use of water
• Landscape development is regarded as a luxury.
Quality of water
• Bacteriological quality
• Chemical quality
• Salinity
• Physical quality
• Quality criteria for water use
