- Description: The National Water Act (NWA, 1998) of South Africa (Act 36 of 1998) aims to ensure that South Africa’s water resources are managed and used in an equitable and sus-tainable manner for the benefit of all. The National Water Act (NWA) requires a dif-ferent approach to managing the nation’s water resources and the concept of inte-grated water resources management (IWRM) is central to this approach (Pollard and Du Toit, 2008). IWRM requires water managers to consider hydrological, ecological, economic, political, social and institutional aspects of water resources. To imple-ment IWRM, water managers require integrated modelling tools to provide infor-mation that can assist in making managements decisions. There are two aspects of integrated modelling that have received increasing attention in recent years: (i) the coupling of models representing different water resource domains, and (ii) the de-velopment of integrated modelling frameworks or decision support systems. These integrated modelling frameworks typically include a common data repository, common data editing tools, common spatial and temporal data visualisation and analysis tools, and a collection of framework compatible models that make use of these common tools.

- Description: The purpose of the National Database is to create a central repository of Reserve or EWR determination results that can be accessed by DWA as well as their service providers to ensure that information is not lost and that the maximum benefit is gained from previous experience for future determinations. This document summa-rises the information content of the database, as well as providing guidelines for entering new data and using existing data. Reference to both Reserve and EWR de-terminations is used as some of the data that are included pre-date the official con-cept of the ecological ‘Reserve’ and were referred to as IFRs at that time. It is ac-cepted, however, that the term ‘IFR’ has been largely superseded by the use of the term EWR or ecological water requirements.
