Short summary
Short summary
Tidal analysis typically relies on continuous water-level data, but many historical records contain only high and low water. We show that these sparse observations can accurately reconstruct tides using a new approach that models peak timing and height directly. The method matches modern high-resolution analyses, is robust to noisy or incomplete data, and enables improved tidal prediction and analysis in shallow and estuarine systems.

Short summary
To gain insight into the sediment transport onto a mid-channel bar in an estuary, we measured current velocities on and along the tidal flat during six months. Our analysis shows that intertidal currents have a more pronounced three-dimensional pattern than those on shore-connected tidal flats. This has consequences for sediment transport and morphodynamics. Existing models for tidal flats underestimate flow velocities and sediment dynamics on mid-channel bars.

The North Passage (NP) is the primary navigation channel of the Changjiang Estuary, supporting the shipping needs of Shanghai and its surrounding regions. To enhance our understanding of hydrodynamics and sediment dynamics of the NP, a multi-year field observation campaign was designed and conducted from 2015 to 2018. This campaign improves the temporal and spatial coverage compared to previous observations, enabling more detailed investigations of this important channel system.

This paper reports on the main findings of a large measurement campaign aiming to better understand how an exposed estuary (the Ems Estuary on the Dutch–German border) interacts with a tidal river (the lower Ems River). Eight simultaneously deployed ships measuring a tidal cycle and 10 moorings collecting data throughout a spring–neap tidal cycle have produced a dataset providing valuable insight into processes determining exchange of water and sediment between the two systems.

The combination of seawalls and vegetation may be the key to Guyana's survival against rising water levels; however knowledge about the system behaviour and use of vegetation is inadequate. This paper comprises the first dataset since the 1970s along the Guyana coastline. Instruments were deployed to capture data on the water levels, waves and sediment locally. Data revealed the ways in which sediment is transported and deposited, as well as the wave damping of the mangrove–mudflat system.

Short summary
Increased salt intrusion jeopardizes freshwater supply to the Mekong Delta, and the current trends are often inaccurately associated with sea level rise. Using observations and models, we show that salinity is highly sensitive to ocean surge, tides, water demand, and upstream discharge. We show that anthropogenic riverbed incision has significantly amplified salt intrusion, exemplifying the importance of preserving sediment budget and riverbed levels to protect deltas against salt intrusion.

Short summary
Two field measurement campaigns in the Dutch Wadden Sea captured how sand and mud move between deep channels and shallow tidal flats. Seabed-mounted frames equipped with multiple instruments recorded water levels, flow velocities, waves, and amounts of sand and mud in the water column and seabed. The resulting dataset helps reveal the processes that control sediment dynamics and the evolution of seabed morphology in tidal coastal systems.
