4.2 Developing Tableau based WA Dashboard for the RBOs (VBA, INMACOM, ZAMBEZI):

The Water Accounting (WA) Dashboards are a web-based tools designed to provide detailed,

multi-year water accounts for the basins water resources. They offer insights into inflows,
outflows, water usage patterns, and availability to support sustainable water resource
