This document outlines a study to assess water quality and detect environmental changes at Mancher Lake in Pakistan using physico-chemical analysis and remote sensing techniques. The objectives are to analyze water quality parameters like pH, COD, BOD, hardness, TDS and EC; assess physical changes in land use/cover; evaluate environmental impacts on water, human health, agriculture and the local economy; and propose restoration plans. The methodology will involve collecting satellite imagery, conducting field surveys, analyzing water samples for various parameters, performing image classification techniques to detect land use changes, and assessing results to evaluate current conditions and impacts.

Present work will focus on the environmental
problem at Mancher Lake due to water quality,
depleting natural resources and unplanned changes
of land used
This scientific study will be focusing on the past
and present conditions of natural resource to
extent environmental related objects using
Remote sensing technology
Water Quality has a significant impact on the
anticipation of water transmissible diseases

Manchar Lake is the largest
freshwater lake in Pakistan and one of Asia's
largest.
It is located west of the Indus River, in jamshoro
District, Sindh. The area of the lake fluctuates
with the seasons from as little as 350 km² to as
much as 520 km²
The lake collects water from numerous small
streams in the Kirthar Mountains and empties
into the Indus River
Nowadays the environmental change has become
the hot issue throughout the world. Land
degradation, industrialization and urbanization
have been creating man-made disasters such as
water quality and global warming.

Remote sensing is a powerful technique for surveying,
mapping and monitoring earth resources
The physico chemicals are the indicator of water quality,
it is necessary to monitor quality with help of analytical
tools
The quality of surface water is largely affected by
anthropogenic inputs such as (municipal and industrial
wastewater discharge).

1.To analyze Physico-chemical parameters such as
(pH), (COD), (B.O.D.), Hardness,(TDS),and (EC).
2. To asses Physical change in the area; Change detection
of land Use/ Cover such as water body, agriculture and dry
land
3. To asses environmental impact
on Water , human, agriculture and social economic
condition of area
4. To propose restoration plan of the lake.

4. The Lake will be divided into two classes main land use/cover, and water body, grass/
barren land
3. Geometrical correct images should be mosaic by image mosaicing method and color
matching scheme will apply on mosaic imagery
2.Geo-referencing correction will be to eliminate geometric distortion using the topographic maps and
field survey Ground control points (GCP) to development geometrical correct images
