Tidal effect and salinity intrusion are two defining characteristics of inland coastal zones, causing, respectively, complex variations in water levels and flows in river and canal networks, and serious problems for agriculture and freshwater fishery, but bringing significant benefits for brackish water aquaculture. To evaluate these conflicts and synergies in the development of agriculture, fishery and aquaculture, this paper adopts a hydraulic and salinity modeling approach that simulates the tidal propagation and salinity intrusion, and evaluates the effects of water and land use management on these hydrology- and salinity-related phenomena in coastal zones. The paper presents the empirical results from the application of a hydraulic and salinity model specifically developed for the context of the Ca Mau peninsula, Mekong Delta, Vietnam, and also demonstrates how such a modeling approach can provide valuable policy-relevant information at different phases for water resource planning, development, operation, and management in hydrologically and environmentally sensitive coastal regions.

By comparing the successful story of a hydrodynamic model (based on its contribution to policy changes, management options and livelihood improvement) with other modelling cases in the Mekong River Delta, five success factors are identified. These are (1) simulated phenomena relevant to and understandable by policy makers; (2) response to the needs of policy setting; (3) developed and handled by national modellers with direct links to the policy process; (4) availability of input data; and (5) long application history. These success factors provide higher opportunities for engaging modelling activities with policy setting.
