Abstract: In the Yellow River Delta, hydrodynamics plays a prominent role. The decreased Yellow River flow and the altered flow regime during the last decades are supposed to be the most likely factors responsible for environmental problems in terms of ecosystem deterioration, habitat evanescence, siltation of the river channel, as well as groundwater depletion and soil salinity increase. The investigation on the ‘minimum water-demand for the ecosystem in the Yellow River Delta' was conducted by the Yellow River Conservancy Commission in the past years. This paper intends to develop the concept of synthetic flows which resemble the flow variability of the natural river state to generate an interactive virtual environment for representing different scenarios. By coupling advanced visualization tools and ecohydraulic methods, decision makers and different stakeholders can explore the dynamic change of the Yellow River Delta from the past to the future. This virtual environment can enable them to have a good interpretation and feel of different database and model results. Meanwhile, using the Hydroinformatics tools such as Remote Sensing and Geographic Information System tools can help the decision makers to generate the rational judgment to the ecological environment around the Yellow River Delta.
