  abstract = {{M}editerranean coastal lagoons and their peripheral areas often provide a collection of habitats for many species, and they often face significant threats from anthropogenic activities. {D}iverse human activities in such areas directly affect the spatio-temporal dynamic of surface water and its ecological characteristics. {M}onitoring the surface water dynamic, and understanding the impact of human activities are of great significance for coastal lagoon conservation. {T}he {R}egional {N}atural {P}ark of {N}arbonne includes a typical {M}editerranean lagoon complex where surface water dynamic and its potential link with local diverse human activities has not yet been studied. {I}n this context, based on all the available {L}andsat images covering the study area during 2002-2016, this study identified the water and non-water classes for each satellite observation by comparing three widely used spectral indices (i.e., {NDVI}, {NDWI} and {MNDWI}) and using the {O}tsu method. {T}he yearly water frequency index was then computed to present the spatio-temporal dynamic of surface water for each year, and three water dynamic scenarios were also identified for each year: permanent water ({PW}), non-permanent water ({NPW}) and non-water ({NW}). {T}he spatial and inter-annual variation in the patterns of the three water scenarios were characterized by computing the landscape metrics at scenario-level quantifying area/edge, shape, aggregation and fragmentation. {F}inally, the quantitative link between different land use and land cover ({LULC}) types derived from the {LULC} maps of 2003, 2012 and 2015 and the surface water dynamic scenarios was established in each of the 300 m x 300 m grid cells covering the study area to determine the potential impact of human activities on the surface water dynamic. {I}n terms of the inter-annual variation during 2002-2016, {PW} presented an overall stability, and {NPW} occupied only a small part of the water surface in each year and presented an inter-annual fluctuation. {NPW} had a smaller patch size, with lower connectivity degree and higher fragmentation degree. {I}n terms of spatial variation during 2002-2016, {NPW} often occurred around {PW}, and its configurational features varied from place to place. {M}oreover, {PW} mostly corresponded to the natural lagoon, and salt marsh (as a part of lagoons), and {NPW} had a strong link with arable land (agricultural irrigation) and salt marsh (salt production), sand beach/dune, coastal wetlands and lagoon for the {LULC} maps of 2003, 2012 and 2015. {H}owever, more in-depth analysis is required for understanding the impact of sand beach/dune, coastal wetlands and lagoon on surface water dynamics. {T}his study covers the long-term variations of surface water patterns in a {M}editerranean lagoon complex having intense and diverse human activities, and the potential link between {LULC} types and the water dynamic scenarios was investigated on different dates. {T}he results of the study should be useful for environmental management and protection of coastal lagoons.},
