Abstract
Abstract. One of the innovative objectives in the EC project BRAHMATWINN was the development of a stakeholder oriented Integrated Water Resources Management System (IWRMS). The toolset integrates the findings of the project and presents it in a user friendly way for decision support in sustainable integrated water resources management (IWRM) in river basins. IWRMS is a framework, which integrates different types of basin information and which supports the development of IWRM options for climate change mitigation. It is based on the River Basin Information System (RBIS) data models and delivers a graphical user interface for stakeholders. A special interface was developed for the integration of the enhanced DANUBIA model input and the NetSyMod model with its Mulino decision support system (mulino mDss) component. The web based IWRMS contains and combines different types of data and methods to provide river basin data and information for decision support. IWRMS is based on a three tier software framework which uses (i) html/javascript at the client tier, (ii) PHP programming language to realize the application tier, and (iii) a postgresql/postgis database tier to manage and storage all data, except the DANUBIA modelling raw data, which are file based and registered in the database tier. All three tiers can reside on one or different computers and are adapted to the local hardware infrastructure. IWRMS as well as RBIS are based on Open Source Software (OSS) components and flexible and time saving access to that database is guaranteed by web-based interfaces for data visualization and retrieval. The IWRMS is accessible via the BRAHMATWINN homepage: http://www.brahmatwinn.uni-jena.de and a user manual for the RBIS is available for download as well.
Highlights
Introduction and objectivesIntegrated river basin studies as done in the BRAHMATWINN project require a common data and information platform that was provided by the River Basin Information System (RBIS) developed by at the FSU-Jena (Flugel, 2007, 2009; Kralisch et al, 2009)
The overall objective was realised by elaborating on the following scientific-technological objectives: 1. Integration of all BRAHMATWINN research work results, data time series, GIS maps and documents from in the Upper Danube River Basin (UDRB) and the Upper Brahmaputra River Basin (UBRB) respectively into the Integrated Water Resources Management System (IWRMS) in such a way that they can be used by means of a web-based graphical user interface (GUI)
The IWRMS modular components are represented by the interface to the DANUBIA model and the mulino decision support system (mDss), a module for Special Report on Emissions Scenarios (SRES) scenario design and the definition and calculation of indicators to be used for integrated water resources management (IWRM) decision support
Summary
Introduction and objectivesIntegrated river basin studies as done in the BRAHMATWINN project require a common data and information platform that was provided by the River Basin Information System (RBIS) developed by at the FSU-Jena (Flugel, 2007, 2009; Kralisch et al, 2009). The IWRMS builds on this well tested toolset and enhanced the latter by integrating data and methods from the deliverables of the BRAHMATWINN project, like the time series of station data, the results of the DANUBIA modelling system (Mauser and Bach, 2009) and the analysis done by means of the NetSyMod-mulino decision support system (mDss) (Giupponi et al, 2008). The overall objective of the IWRMS development was to offer users and decision makers the DANUBIA modelling results (Chapter 7) together with the “what-if?” scenarios elaborated by the mDss (Chapter 8). Integration of all BRAHMATWINN research work results, data time series, GIS maps and documents from in the Upper Danube River Basin (UDRB) and the Upper Brahmaputra River Basin (UBRB) respectively into the IWRMS in such a way that they can be used by means of a web-based graphical user interface (GUI). Making the comprehensive system assessment, modelling studies, spatial analysis of water balance components and the integrated socio-economic analysis and scenario evaluation available to local actors, decision makers and planners
