Archaeological Investigation At Dholavira

 

Scope of Work:

GPR survey execution for mapping of potential locations containing archaeological features underneath for excavation purposes

Location:

Dholavira, Gujarat, India.

Client:

Archaeological Survey of India

Equipment:

GSSI SIR-3000 equipped with 100, 200 MHz and 400 MHz antenna

Challenges:

Data analysis and interpretation for uncertain archaeological features was a big challenge

Summary:

A new area at an existing archaeological site of Harappan civilization at Dholavira, Gujarat, India has been studied using ground penetrating radar (GPR). An area of 12,276 sq. m. was surveyed using 200 MHz antenna at grid spacing of 2–3 m. The soil strata was found to extend mainly up to 3.5–4 m. The survey was conducted during the dry season to collect good signals. Post-processing was carried out to map the bedrock as well as archaeological features. A number of linear features were observed from the 3D image of the subsurface created from the acquired GPR profiles. Unlike residential structures, the large dimensions of these features indicate the likely existence of a series of water structures that may have partly collapsed due to floods at some point. There were some areas full of rubble next to the damaged walls that appeared to be orthogonal to the direction of possible flood from Manhar River.
