Morfodynamics and sedimentation of a sector of parana delta front between 1933 and 2016, province of Buenos Aires, Argentina
In recent times, the fast population growth of Tigre islands, San Fernando and San Isidro localities has attracted the attention of several urban planners. Consequently, the price of the lands has increased, as well as the exploitation of natural resources. This paper examines the morphodynamic beha...

Consequently, the price of the lands has increased, as well as the exploitation of natural resources. This paper examines the morphodynamic behavior of Parana delta front between the rivers Lujan and San Antonio channel since 1933, to analyzing recent changes in delta landforms, subenvironments, dynamics and sedimentological patterns.

It was obtained a delta front progradation rate between 42.30 m/year to 45.13 m/year since 1933. This fast progradation changed several delta subenvironments and ecosystems; not only along the delta coast, but also along the estuary coast.

Also the Lujan river would extend toward the estuary for about 1.300 m, changing dynamics and environment of the coast of San Isidro. Therefore it is very important in a near future to diagram, plan and legislate previously; the occupation of these new territories to avoid future social, economic, political and cultural conflicts. © 2018, Taylor and Francis Ltd.

In recent times, the fast population growth of Tigre islands, San Fernando and San Isidro localities has attracted the attention of several urban planners. Consequently, the price of the lands has increased, as well as the exploitation of natural resources. This paper examines the morphodynamic behavior of Parana delta front between the rivers Lujan and San Antonio channel since 1933, to analyzing recent changes in delta landforms, subenvironments, dynamics and sedimentological patterns. These results are useful to establish strategies for the coastal management of Tigre, San Fernando and San Isidro localities. Parana delta front has moved episodically towards the estuary adjoining distributary mouth bars increasing consequently the subaerial surface of the lower delta plain. Four distributaries mouth bars were adjoin to the delta plain during the decadal episodes of 1935-50, 1960, 1980 and 2000. It was obtained a delta front progradation rate between 42.30 m/year to 45.13 m/year since 1933. This fast progradation changed several delta subenvironments and ecosystems; not only along the delta coast, but also along the estuary coast. The evolutive delta model obtained estimates that, in 2050, a land surface of 3914 m2 could be incorporated to the delta in the studied area. Also the Lujan river would extend toward the estuary for about 1.300 m, changing dynamics and environment of the coast of San Isidro. Therefore it is very important in a near future to diagram, plan and legislate previously; the occupation of these new territories to avoid future social, economic, political and cultural conflicts. © 2018, Taylor and Francis Ltd.
