Systematic Application of Degradation Model for Environmental Impact Assessment of Lation Watershed

It is fair to say that the man by including agricultural, industrial activities
and exploitation-of natural resources in his survival agenda is the most
responsible of all for environmental changes.
Fundamentall development in various parts of a watershed is unavoidable
and sometimes necessary. In recent years, large number of
environmentally improper developments including new town development
have taken !place around Latian lake (dam), which have led towards
construction with out proper engineering and environmental observations.
The aim of this research work is assessment and measurement of
degradation due to inappropriate development in environment.
Degradation : Mode] is one of the important tools in quantification of
environmental degradation. This model is a systemic analysis type and
uses mathematical model that yields development effects of a region in the
shortest possible time. In another word, it reduces time and cost for
evaluation process.
In this work, borders of watershed have been drawn to scale of 1:50,000.
The region has been divided to 748 units (i.e, 2cm x 2cm grid) which each
grid covers :an area of 1km2. The degradation model for each individual
unit has been applied by employing computer programs.
It was found that 510 units (68% of total) are unfit for development,
because of certain .inappropriate conditions. Also 149 units (i.e. 20% 0
total) were ideteriorated by human activities that have lost potential for
proper development
