River deltas are usually densely populated with intensive and prosperous socioeconomic activities, and the hydrological processes in these delta regions are complex due to river-aquifer-sea interactions. However, a systematic and quantitative elaboration of the river-aquifer-sea interactions is still lacking. Here we developed an integrated hydrological model for the Pearl River Delta (PRD), which contains the world’s largest urban area in both size and population, to gain a deeper understanding of the complexities in the river-aquifer-sea interactions. The model performance was validated and cross-checked via observations at gauging stations and independent remote-sensing products (e.g., soil moisture, ET and total water storage anomalies). Based on the 10-year simulation results, key regional hydrological processes were explored, river-aquifer interactions and sea-aquifer interactions were quantified, and factors influencing the interaction processes were investigated.
