Short summary
For many problems concerning water resource utilization in estuaries, it is essential to be able to express observed salinity distributions based on simple theoretical models. In this study, we propose an analytical salt intrusion model inspired from a theory for predictions of flood hydrographs in watersheds. The newly developed model can be well calibrated using a minimum of three salinity measurements along the estuary and has been successfully applied in 21 estuaries worldwide.

The circulation patterns of surface water over the northern Gulf of Cádiz are described based on hourly high-frequency radar data from 2016 to 2020. A persistent current follows the continental shelf slope eastward while near the coast, and currents generally have a balanced (eastward–westward) direction. In summer cross-shelf transport is promoted when westward coastal countercurrents recirculate offshore in the western region and merge with the slope current.

Quantifying spatial–temporal water level dynamics is essential for water resources management in estuaries. In this study, we propose a simple yet powerful regression model to examine the influence of the world’s largest dam, the Three Gorges Dam (TGD), on the spatial–temporal water level dynamics within the Yangtze River estuary. The presented method is particularly useful for determining scientific strategies for sustainable water resources management in dam-controlled estuaries worldwide.

This paper develops a novel set operations of coefficients of determination (SOCD) method to explicitly quantify the overlapping and differing information for GCM forecasts and ENSO teleconnection. Specifically, the intersection operation of the coefficient of determination derives the overlapping information for GCM forecasts and the Niño3.4 index, and then the difference operation determines the differing information in GCM forecasts (Niño3.4 index) from the Niño3.4 index (GCM forecasts).

Short summary
Overtide is a shallow water tidal component and its interaction with astronomical tides induces tidal wave deformation, which is an important process that controls sediment transport. We use a numerical tidal model to examine overtide changes in estuaries under varying river discharges and find spatially nonlinear changes and the threshold of an intermediate river that benefits maximal overtide generation. The findings inform management of sediment transport and flooding risk in estuaries.

Short summary
Understanding tidal hydrodynamics is essential for water resources management in estuarine environments. In this study, we propose an analytical model to examine the fortnightly water level variations due to tidal motions alone in tide-dominated estuaries. Details of the analytical model show that changes in the mean depth or length of semi-arid estuaries affect the fortnightly tide amplitude, which has significant potential impacts on the estuarine ecosystem management.
