MINOR PROJECT REPORT

HYDRAULIC ANALYSIS OF
SUKHNA CHOE
AND
PATIALA KI RAO CHOE

ABSTRACT

 About 4.72 % of the total area of the U.T. is under water bodies. This includes Sukhna wetland (1.6%) and seasonal rivulets (3.12%), like Sukhna Choe, Patiala-ki-Rao, N Choe and Choe Nallah. Two seasonal rivulets viz. Sukhna Choe in the east and Patiala-Ki-Rao Choe in the west. The central part forms a surface water divide and has two minor streams. The stream passing through the central part is called N-Choe and the other is Choe Nala which initiates at Sector 29. We aim at collecting the river characteristics like flow data, stream data of the two streams- sukhna choe & Patiala ki rao choe. So that we bring out a way to channelize them and use them for our sustainability and for the same we are getting into the knitty-gritty of the software HEC-RAS 4.1 HEC-RAS is designed to perform one-dimensional hydraulic calculations for a full network of natural and constructed channels. it contains four one-dimensional river analysis components for: (1) steady flow water surface profile computations; (2) unsteady flow simulation; (3) movable boundary sediment transport computations; and (4) water quality analysis.  In addition to the four river analysis components, the system contains several hydraulic design features that can be invoked once the basic water surface profiles are computed.

INTRODUCTION

Chandigarh, known, as the “CITY BEAUTIFUL” is a Union Territory (U.T.) located at the foothills of the Shiwaliks about 250 kms. north of New Delhi. The city also has the distinction of being the joint capital of Punjab andHaryana states even though it does not form part of any of the two States. Itlies between north latitudes 30o 40’ and 30 o 46’ and east longitudes 76o 42’and 76o 51’.Punjab stateborders the UT in the south and south-western sides and Haryana state one eastern side. UT of Chandigarh has an area of 114 sq.km., out of which 36sq.km. is rural and remaining 78 Sq.km, is urban. The city is divided into 55dwelling sectors. As per census 2001, total population of the city was9,00,635persons having a population density of 7903...
