Water resources management has become a field where computer-aided analytical techniques are expected to facilitate a complex process of decision making which involves several stakeholders with varied interests and various socioeconomic objectives of the natural resource development and management strategies. In many ways, the decision-making related to water resource management exhibits a political process that requires water resources engineering expertise combined with suitable use of informatics. This paper investigates the case of South Africa to assess the extent to which various computer-based decision support systems have succeeded in terms of addressing the socioeconomic objectives encompassed under the new vision for water resources management. Prevailing gaps have been identified through an exhaustive review of relevant initiatives in the country and abroad. A conceptual recommendation has been made to address the identified gaps while highlighting the challenges that lie ahead.
