BRAHMATWINN - BrahmaRBIS & DanubeRBIS

Data and information related to the results of BRAHMATWINN have been input in the Riber Basin Information System (RBIS) as a central component of the Integrated Water Resource Management System (IWRMS) which is the ultimate goal of the project.

The BrahmaRBIS & DanubeRBIS are repositories that centralize the data outcomes related to the following research actions performed in both the Upper Danube River Basin (UDRB) and the Upper Brahmaputra River Basin (UBRB): 

  • Application of the regional climate model COSMO-CLM to downscale a Global Circulation Model from global to regional projections. The projections have shown an increase of temperature in both basins and for all seasons. Annual precipitation shows no substantial change. However, seasonal amounts show clear trends, for instance an increasing amount of spring precipitation in the UDRB. The results focus on the most pronounced trends in the UDRB and the UBRB during the years 1960–2100.
  • Understanding of the interplay between natural environment and human activity. These interactions, their dynamics and changes, and future scenarios were investigated with a series of tools such as remote sensing devices and geoinformatics.
  • Assessment of socio-economic vulnerability regarding climate change.
  • Analysis of current Integrated Water Resources Management (IWRM). The study has shown that the IWRM approach is already part of water management planning in the UDRB. In the UBRB, however, the implementation of IWRM is just at the beginning phase.
  • Development of integrated indicators relevant to IWRM for providing stakeholders with an overview of the present status and trends of the river basins water resources resulting from climate change.
  • Calculation of the impact of climate change on the water balance of both basins (UDRB and UBRB). Time series from 2011 to 2080 according to a number of IPCC SRES emission scenarios were analysed.
  • Development of responses to flood risk and socio-economic vulnerability in both basins (UDRB and UBRB) given future climate change scenarios. The outcomes were summarized in Integrated Water Resource Management Strategies based upon the issues and preferences elicited from local experts.

All the outcomes corresponding to the described research actions were collected and integrated into the RBIS. It provides a common repository and organisation structure for the overall project outputs ultimately playing the role of a Decision Information Support Tool (DIST).
