This paper presents three interacting models that facilitate the establishment of water management policies targeting sustainable
and equitable use of water. For a given sub-basin, the water balance model attempts to establish the balance of
water flows across the system boundary. Considering the whole system, the inflows have to balance the outflows. However,
the water use model, set inside the system, allows for water within the system to be used many times over, thus increasing
water availability. The water security model defines a multi-dimensional metric for water security depending on the water
use model. The model structure allows for compatibility across boundaries, enabling construction of a composite mode
for a basin, and hence a model for the country considering trans-basin exchanges.
