"Along coastlines, where tides are typically magnified, they profoundly affect navigation, commerce, coastal flooding, water properties and sediment transport. Tides impact the flooding of rivers and, thus, influence the extent of their floodplain, which has cascading effects on biogeochemical and ecological processes."
"Tidal flooding also accelerates both nitrification and denitrification in soils, leading to variable effects on nutrient levels and coastal water quality. Tides enhance the mixing of saline and freshwater along river channels, which affects water security in coastal cities and food security for agricultural deltas that use river water for irrigation."
"Despite their importance, the extent of tides in coastal rivers is poorly known on a global scale because tidal propagation depends on the unique morphologic and hydrologic conditions of each river as well as the magnitude of the tidal signal at the river mouth."
Tides, derived from the Latin 'aestuarium' meaning place of the tide, are fundamental to coastal and estuarine systems. They influence navigation, commerce, coastal flooding, water properties, and sediment transport along coastlines. Tidal cycles modulate river flooding and floodplain extent, affecting biogeochemical and ecological processes. Tidal flooding accelerates nitrification and denitrification, impacting nutrient levels and coastal water quality. Tides enhance mixing of saline and freshwater, affecting water security in coastal cities and irrigation in agricultural deltas. They are critical factors in compound coastal flooding events. Despite their significance, global understanding of tidal extent in coastal rivers remains limited due to unique morphologic and hydrologic conditions of individual rivers and insufficient observational data.
