In addition to execution of flood management work and collection of hydro meteorological data, the Water Resources Department established a River Research Station (RRS) in 1958 , comprising of two numbers of research division comprising Soil Research Division and Hydraulic Research Division to carry out necessary sub-soil investigation and hydraulic model studies for flood and erosion management projects.
In 2013, with an aim to establish a Centre of Excellence for Knowledge and Technology in the field of Water Resources Management in North East India, the River Research Station was converted to the Assam Water Research and Management Institute (AWRMI).
The Major Activities of Assam Water Research and Management Institute (AWRMI) are
- Geo-technical exploration and investigation
- Hydrological modelling
- Data Center
- Sectional Assistant Training Centre
- Research and Development activities and Capacity Building
- Organising workshops, seminars, conferences, etc
- Setting up of Brahmaputra gallery
Geo-technical exploration and investigation
Soil laboratory activities includes physical identification of soil samples, grain size analysis, dry and wet sieving, hydrometer, specific gravity, atterberg's consistency, liquid, plastic limit, plastic index, moisture content, wet and dry densities, void, porosity, submerged and saturated densities, unconfined compression test, cohesion, angle of internal friction(0), consolidation parameters, standard proctor compaction test (OMC & MDD), Angle of repose(0) etc.
The RRS functioned well till the late nineties and a lot of work on investigation and physical modelling was being conducted by this centre.
In August, 2014, a Data Center has been set up at AWRMI which will be a repository for existing data relevant to Brahmaputra and Barak Rivers and its tributaries.
The basic objective of the data centre is to digitize the hydro meteorological data like HFL, LWL, discharge, cross sectional area, velocity, precipitation, suspended sediment load etc.
Research and Development activities and Capacity Building
AWRMI is being developed to take up Research and Development activities and Capacity Building of in-service officers of Water Resources Sector in Assam
In-house capacity building trainings on engineering, project management, life skills development, etc. are carried out
Center of Excellence
In order to cope up with the present scenario of water related issues like climate changes and other water related disaster etc. the AWRMI is proposed to be upgraded to a center of excellence. In these contacts the center of excellence is formed as a society. To house the center of excellence, construction of a green building is under progress. This green building is going to be the first of its kind in the entire Northeast region. Further this center of excellence is planned to be upgraded to a regional Data and Research centre covering the entire Northeast region.
Taking up the project – ‘Guwahati Field Trial'
Based on the results presented to NGOs and Government Organisations in Assam, the BRAHMATWINN coordinator, Prof. Dr. Wolfgang-Albert Flugel from Friedrich Schiller University of Jena, Germany and his project partner, Prof. Dr. Nayan Sharma from IIT Roorkee were requested by the Chief Minister of Assam to prepare a RECLAIM project concept note.
The overall objective of the RECLAIM project is to implement the basic constituents and components for a Brahmaputra River Master Plan (BRMP) for the North-East Region (NER) of India.
As a pilot initiative for the RECLAIM Project, the Field Trial Project was proposed by Prof. Flugel with the following basic objectives:
- Integrated System Analysis (ISA) comprising remote sensing analysis of erosion dynamics and river bed development.
- Implementation of a web based River Basin Information System (RBIS) and its enhancement towards a comprehensive Decision Information Knowledge System (DIKS) for Assam.
- Modelling of the Brahmaputra River tributary runoff and sediment input contribution from the landscape to the main river stretch.
- Quantification of the impacts of enhanced river training measures with respect to bank erosion dynamics and land reclamation.
- Development of a Decision Support System (DSS) for the development of holistic river training strategies and integrated monitoring concepts.
The selected test site for the experimental field trial study is at the southern bank of the Brahmaputra River about 2.5 km west of the Saraighat bridge. Satellite imageries from 2003 to 2013 were analysed and the river braiding pattern has been observed. Further study on hydrological and hydraulic modelling is being carried out by Prof. Flugel and his team.
