Explanation:

PROFILE OF SURVEY MAP 45 D/7

DESCRIPTION of the Area covered by Survey Sheet No. 45 D/7 (Gujarat and Rajasthan)

District : Banas Kantha and Sirohi

Location: Latitude 24 degree 15’ – 240 30’ North

Longitude 720 15’ - 720 30’ East

This region lies in western India on the borders of Rajasthan and Gujarat at the southern end of the Aravalli Hills, immediately north-east of Sheet 45 D/10.

RELIEF : The area is mainly a plain except for:

1. The east central region where the hills rise to almost 500 m.,

2. The lower hills of the north-east corner.

The slope of the land is from north-east to south-west in the northern half and east to west in the southern portion of the map. (indicated by flow of rivers)

DRAINAGE

1. The Banas river (not to be confused with the Banas river which is a tributary of the Chambal river to the north) flows into the swampland area of the Little Rann, north-east of the Gulf of Kutch. On this survey sheet it flows westward. It has two main right bank tributaries – Sarod and Arado Nadis and the numerous smaller streams like the one entering the river near Chekla (8192). The only left bank tributary is the Balaram Nadi from the south-east. The Banas river varies in width from 1/4km to over 1 km and has a narrow perennial water course. The dry portion fills in during the rainy seas.

Answer 2

There is there absence of the settlement in the northeast as well as  western part of the map​

Explanation

• On a topography map, all settlements are indicated  by symbols in RED color. The size of the symbol & size & style of letters give an idea of the the settlement size.
• Absence of Settlements is mainly because of the presence of  Swamps, sandy deserts, marsh land, flood-prone areas, thick impenetrable forests, or steep mountain slopes.
• The above region in the map is densely forested, with several  streams with very steep hills. and as such it is expensive to construct/build roads. That is why there is the absence of "human habitation" in the north east and western part of the map​
