RakNam : A Prediction and Scenario-based System for Saltwater Intrusio.

Bangkok metropolis and its vicinity largely rely on the Chao Phraya River in supplying the freshwater. The salinity in the Chao Phraya River is controlled by ocean tides and river discharge thus the interplay between these two factors is crucial in determining the availability of freshwater. Besides, the surges can play an essential role in the enhancement of the salinity concentration during the monsoon seasons.

The saltwater intrusion is intensified in the dry season when the demand of fresh water is excessively high affecting various sectors including agriculture, industry and waterworks. The decision support system, RakNam, which includes the saltwater intrusion forecasting and scenario-based planning capabilities, has been developed to help decision makers make critical decisions on the timing of the availability of freshwater in the Chao Phraya River. Specifically, modeling of riverine-coastal ocean hydrodynamics and mass transport process, investigating the regional and local saltwater dynamics in the area, designing an effective assimilation scheme and developing a supporting web-application have been established.
