River Basin Data Base

The main type, called RIVER BASIN OBJECTS, represent real world entities: such as (sub)catchments, reservoirs, cities, or treatment plants (all georeferenced) and generic objects such as
• water technologies
• crops (potentially irrigated).

For any given catchment, it provides:

• A basic description of the basin, hypertext and images, parallel map display, selected descriptive parameters, summaries of landuse and elevation (pie charts that link to detailed topical editors and display pages)

• A set of navigation BUTTONS that lead to further related pages. These are, starting from top left:
  • Economics: defines the relative contributions of main economic sectors to overall basins GRP;
  • Demography: age-sex distribution as the basis of demographic forecasts and scenarios;
  • Institutions: an address data base for individual and institutions design for the support of stakeholder groups and a participatory apporach to IWRM;
  • Documents: a simple doument management system (PDF, DOC, PS) for documents related to the basin;
  • Demand: leads to a list of all the major water users (demand nodes) such as cities, irrigation districts and large farms, industries, tourist resorts, wetlands (environmental demands);
  • Monitoring: monitoring stations and their associated data sets (time series); may be related to institutions as their operators;
    
    • Structures: major hydraulic structures, primarily dams and reservoirs, but also weirs, sluices, pumped abstractions, well fields, treatment plants;
    • Issues: questionnaires on water resources issues, related to institutions, in support of a participatory DSS approach (elicitation of stakeholders priorities and preference structures).
