“…Moreover, tidal inlets are essential for shore and dune processes and the exchange of both water and sediments (Fortunato et al, 2014). Their dynamics are mainly controlled by complex interactions between different drivers (wind, tides, or waves) and the interactions with their own topographic features (Vikas et al, 2015).…”

Despite relevant advances achieved in recent years, sediment transport and sedimentation problems at tidal inlets are still worldwide issues to be addressed. Furthermore, dredging strategies are carried out following traditional layouts, such as channel deepening, lasting short periods of time despite the high economic expenditures and the potential environmental impacts. This work proposes a new dredging strategy for tidal inlets and analyzes its morphodynamic evolution by means of numerical modeling. This numerical model, used to perform hydro-morphodynamic simulations, is applied to a highly altered tidal inlet (Punta Umbría inlet, Southern Spain) with a navigational capacity being continuously compromised. After calibrated and tested, the model is applied to different dredging strategies, including channel deepening, littoral drift barrier and shoal removal. Among these strategies, the shoal removal, which is a new soft-engineering strategy,

“…The relative tidal range (RTR) was calculated using the mean spring tidal range (MSR) and the breaking wave height (H b ) (after Masselink and Short, 1993) where RTR = MSR/H b . The dimensionless relative tidal strength (R T/W ) (Equation 2) (as proposed by Vu et al, 2014 and applied by Seelam et al, 2014;Vikas et al, 2015) was calculated for all sites to further quantify the relative balance of tide and wave dominance.…”

Intermittently Closed/Open Lakes and Lagoons: Their global distribution and boundary conditions

et al. 2017

Intermittently Closed/Open Lakes and Lagoons (ICOLLs) are a particularly dynamic form of estuary characterised by periodic entrance closure to the ocean. Closure occurs when a subaerial sand berm stabilises across the entrance channel during times of low fluvial discharge. ICOLLs are of global importance as they provide valuable ecological habitats for many species and are associated with a wide range of management issues due to their cycle of entrance closure and opening. ICOLLs are found to be more widespread globally than previously described with 1477 of these estuaries being identified in this study. This constitutes an estimated 3 % of the world's estuaries and 15 % of all estuaries along microtidal coastlines. ICOLLs are concentrated along microtidal to low mesotidal coastlines in the mid-latitudes and predominantly on coasts with temperate climates. This distribution is related to greater wave heights as driven by high intensity winds and a longer fetch distance.The highest proportion of ICOLLs are present in Australia (21 % all global ICOLLs), South Africa (16 %) and Mexico (16 %). In Australia, a comparison with fluvial input found that it is less important than marine processes in determining ICOLL formation and that ICOLLs are associated with a relative tidal range of < 3.22. Additionally the majority of ICOLLS are small systems with catchments < 2000 km 2 and tidal prisms < 30 x 10 6 m 3 , forming at the mouths of rivers with generally low mean annual and specific discharges. Highlights Intermittently Closed/Open Lakes and Lagoons (ICOLLs) are concentrated in the midlatitudes globally  They are found along coastlines with a micro-to low meso-tidal range and predominantly on coasts receiving storm waves and east and west coast swells  1477 of these systems were observed worldwide which constitutes approximately 3 % of the world's estuaries ACCEPTED MANUSCRIPTA C C E P T E D M A N U S C R I P T  Coastal processes appear to dominate over river hydrology in both the opening and closing of estuary mouths. KeywordsICOLL, estuary, coastal lagoon, estuary distribution IntroductionEstuaries are geomorphic systems which represent the transition between fluvial and marine environments (Boyd et al. 1992; Cooper, 2001;Roy et al. 2001). Their morphology is a direct function of the interaction between river outflow, waves and tides acting over a pre-existing catchment morphology (Dalrymple et al., 1992;van Niekerk et al., 2005). One key determinate of estuary morphodynamics is entrance condition. The larger the entrance channel, the greater the exchange of hydrodynamic energy and sediment (Bruun, 1986; Hume and Herdendorf, 1993 (Neira and Potter, 1992; Ranasinghe et al., 1999;Ranasinghe and Pattiaratchi, 2003). We refer to these systems as Intermittently Closed/Open Lakes and Lagoons (ICOLLs), a term ACCEPTED MANUSCRIPTA C C E P T E D M A N U S C R I P T which has been most widely applied internationally (Roy et al., 2001;Schallenberg et al., 2010;Astel et al., 2016;Netto and Fonseca, 2017).ICOLLs a...

“…Moreover, these habitats support unique flora and fauna, including migrants and residents of various aquatic species (Sreekanth et al, 2016). In Maharashtra, 48 tidal creeks have been reported (Vikas et al, 2015) and most of these creeks are rich in fish diversity and abundance which support the traditional dol net fishery. Dol nets are location-specific stationary bag nets extensively used in the tidal creeks of Maharashtra to harvest fish.…”
