4.2.2 Secondary Data Collection
VOLUME III:
ENVIRONMENTAL IMPACT ASSESSMENT
Secondary data collection has been collected primarily on regional environmental and social
features from various Government Agencies/Institutions and through literature reviews. Such
information includes Hydrogeological Atlas of Gujarat, Central Ground Water Board. Information
on climate available from IMD data, information on soil & geology has been obtained from
available maps (from National Atlas & Thematic Mapping Organisation -NATMO) and also from
respective websites.
For Socio-economic profile of the influence area along the project corridor, the database for
analysis has been taken from Census of India (1991 & 2001) and other secondary sources.
4.3 LAND ENVIRONMENT
4.3.1 Physiography and Terrain
The project region is located in Rajkot and Junagadh district in Gujarat. Rajkot district is situated
in the central part of the Saurashtra Peninsula. It lies between the parallels of latitude 21°31’ and
23°10’ and the meridians of longitude 70°1’ and 71°30’. Rajkot district is a part of Kathiawar
Peninsula and is sub-divided into five sub-micro regions such as Maliya Coastal Plain, Rajkot
Alluvial Plain, Rajkot Stony –Waste Land, Bhadar River Plain and Vinchhiya Upland. The project
corridor falls in the Bhadar River plain. The eastern part of the region is above 200 metres while
the western part has an altitude of 100 metres above M.S.L. The general slope of the region is
towards south-west. The district is bounded on the west by Junagadh district.
Junagadh district is situated at Saurashtra region and form part of the Kathiawar peninsula. It lies
between the parallels of latitude 20°41’ and 21°41’ and the meridians of longitude 69°56’ and
71°13’. It is sub divided into four sub-micro regions namely, Junagadh coastal plain, Bhadar, Ojat
and Harna river plain, Girnar hills and Junagadh Gir forested Region. The elevation of the region
falling in Mangrol, Manavadar, Keshod, Malia and Patan-Veraval talukas varies between 5
metres and 52 metres above the M.S.L in the Junagadh Coastal Plain. Some parts of Mangrol,
Manavadar, Keshod, Malia, Patan-Veraval, Vanthali, Junagadh talukas falls in the Bhadar, Ojat
and Harna River Plain which elevates between 45 metres and 241 metres above M.S.L.
The proposed alignment traverses through fertile plain terrain along its entire length. The
physiography of the project area is depicted in Figure 4-1.
