This is a pilot study to explore the feasible sites through SRS/GIS technology from where the flood water can be diverted and managed to reduce flood risk and store it for productive use.

OVERVIEW

Tarbela is the major dam on river Indus. Its storage capacity has been reduced to about 2/3rd and there is an urgent need of planning to increase the water storage capacity and reduce its wastage. For the purpose more water reservoirs are required.

• Whenever there are heavy rains these convert into huge floods. These Floods

are needed to be controlled and diverted to the areas where it cause least damage to population as well as agriculture.

• Chashma Jhelum Link Canal from Chashma Barrage will Carry the Flood Water

and From Adhi Kot Bridge at Chashma Jhelum Link Canal the new Canal will be Built to make this water reach to the proposed reservoir Site.

SIGNIFICANCE

• Pakistan is an agricultural economy and growing population

demands more and more land to be cultivated that in turn requires more water.

• Thousands of acres of land is uncultivable due to water deficiency

and mostly unavailability.

• The area where the flash flood water will be diverted and stored

can provide them drinking water as well as their food requirements.

TECHNIQUES

• This entire study has been carried out RS/GIS

frame work. The data used is Landsat TM, Spot-5 and DEM.

• Contour based Surface Elevation Modeling
• Settlements and Population Saturation

Command Area: A significant amount

• f

water including that due flash flood can be diverted and injected in to Jhelum river area by using this command area.

Topographic Gradient Modeling

Regional Topographic Gradient Model has been developed

Study Area Contain 6 Major Settlements with total Area 3.6 Sq Km and Average Area 0.6 Sq km. Estimated Population is 3600 people

There are 46 Small Settlements in our study area and their total area is 1.07

• Sq. km with average area

0.02 Sq. Km. Estimated Population of Smaller Settlements is 1000 people

Population Estimation

Population Estimates are made statistically and by the information collected from local people Total Area of Settlements in the Study Area=4.67 Sq. Km In Study Area 1 Sq. Settlement contain= 100 Homes Each Home Contain = 10 People 4.67 Sq Km Area will have = 467 Homes So Toatal No Of People = 4670 People
