CS(AR)-19/98-99 : Preliminary hydrological investigations of Deepar Beel and strategies for its monitoring and management.

Abstract

Deepar Beel on which the present study is focused is a natural fresh water lake locally known as "Beel". Situated on the south-west fringe of the Guwahati city, the beel covers an area of about 40 sq. Kms. The beel serves as a major natural storm water reservoir for the entire Guwahati city. The geology of the surrounding, the hydrology of the inflowing and out flowing streams viz. the Bharalu, Kalmani, Basistha and Khanjan and the nature of land use in the adjoining area greatly influenced the beel development and transformation in the present day status. The quality of soil and water of Deepar beel and its connecting water bodies and the concentration of trace elements in the bottom sediments of the beel is reported herein. Initial attempts on evaluating and monitoring the quantity and quality of the beel water is also mentioned here in. Detailed project plan to investigate the hydrology of the Deepar Beel are presented in this report. The numerical models to be developed for proper monitoring and management of the beel is discussed and outlined in this report.
