From touristic villages to coastal cities: The costs of the big step in Buenos Aires

摘要: Abstract Coastal villages have grown due the increasing touristic demand of “sun and beach” resorts. This implies more services, areas for bathing shadows tourists. The awkward assessment beaches shortages induced by natural erosion provoked deterioration zones. coastal defence policy management rain excesses can not reverse this trend. Storm-water discharges in many places are constructed towards zones combined sewer overflows (CSO) systems that increase pollution problems. decrease width beach interventions. Hard structures (seawalls, groynes) probed to imply worse impacts; nourishment does solve problem but permits rebuilt or modify some under critic stages. pavements seaside avenues been very controversial cities subject storms. Sewage networks were originally oriented sanitary ponds odours water table led reconsider master plans. At same time, groundwater is shortening end season new reserves should be planned. However, federal governments do envisage magnitude future problems, neither impacts climatic changes. In sense, it necessary propose alternative coastal-defence policies, avoid pluvial areas, promote aquifer recharges sewage network submarine outfalls.
