On “radiational” tides and their interpretation as frictional effects

An Integrated Resilient Sediment Transport RIsk Management (IRSTRIM) Approach for Estuaries

“…• Tidal asymmetry index Coastal managers need to make informed decisions to increase the resiliency of estuaries against sediment transport risks [56][57][58]. Morphodynamics and sediment transport in estuaries majorly depend on tidal asymmetrical behavior and variability and its consequent effects [59][60][61][62][63][64].…”

River, tide and morphology interaction in a macro-tidal estuary with active morphological evolutions

“…River-tide properties can vary in systems subject to strong fluctuations of river discharge. The effects of river flow on tidal dynamics are known, mostly based on analytical solutions or numerical models (Godin, 1991;Kukulka and Jay, 2003a,b;Jay et al, 2011;Sassi and Hoitink, 2013;Cai et al, 2015Cai et al, , 2020. There are basically four direct influences of high river discharge: (1) increased ebb currents, favoring the growth of overtides and causing tidal damping; (2) increased water levels and water depths, which means lowering the bed resistance; (3) changed hydraulic drag via changing of suspended sediment concentrations; (4) bed level change.…”

“…1b), friction effects decrease with the water depth. Meanwhile, the landward increase of water depth also reduces the hydraulic drag (Godin, 1991;Jay et al, 2011;Wang et al, 2019).…”

“…River discharge is rarely constant and can vary rapidly over a large range, which induces a highly nonstationary behavior of tides in estuaries, especially into the landward direction (Guo et al, 2015;Jay et al, 2011;Kukulka and Jay, 2003a,b). A higher river discharge dissipates tidal energy, slows down tidal wave propagation and reduces the tidal range by enhanced bed friction (Godin, 1991;Cai et al, 2012;Zhang et al, 2015a). The river-tide interaction causes a higher mean water level during spring tide than during neap tide, explaining the fortnightly oscillations in mean water level (Matte et al, 2014).…”

Ocean tides in the continental margin off the Pacific Northwest Shelf

“…Munk and Cartwright [1966] and Cartwright et al [ 1988] attribute the deviations to the response of the ocean to solar radiation (hence the term "radiational" tide). However, Godin [ 1986Godin [ , 1989 shows from observations in gulfs, straits, and rivers that in coastal regions these tides are more likely the result of nonlinear friction. He also states that these nearshore effects should be observable in the offshore tides because they should extend seaward through "continuity."…”
