Since the novel coronavirus was reported (December 2019), the virus spread rapidly breaking through frontiers and impacting almost all countries of the world. Tourism is one of the sectors that has been heavily affected by the crisis. Even though there are several protocols for tourism activities that were written for the austral summer season, at the present, physical distancing is considered an effective way to reduce the spread of the virus. Clear and simple public actions should be rapidly implemented by the authorities to minimize the number of people on the beach. For instance, increasing the number of accesses to the beaches, building parking lots adjacent to the farthest beaches, or opening coastal roads on the outskirts of town to expand usable beaches, would be some simple and direct measures to reduce the beach population density. A simple analytical formulation for assessing the percentage decrease of the static population density respect to the absolute maximum population density on a beach is described in this paper. The variables of this simple analytical tool are the instantaneous sea-level (tide), air temperature, and beach expansion. Beach expansion is the single and manageable variable of the formulation, and refers to the inclusion of some near or adjacent extension of beach. It is suggested that the expansion of beaches would be very useful not only for pandemic time but also for the new normality. An application of this methodology is presented in the municipality of La Costa, Argentina.
自新型冠状病毒被发现（2019年12月）以来，该病毒迅速传播，跨越国界，影响了世界上几乎所有国家。旅游业是受这场危机严重影响的行业之一。尽管针对澳大利亚夏季旅游活动制定了多项协议，但目前，保持身体距离被认为是减少病毒传播的有效方法。当局应迅速采取明确、简单的公共行动，以尽量减少海滩上的人数。例如，增加通往海滩的通道数量、在最远的海滩附近修建停车场，或开放城镇郊区的沿海道路以扩大可用海滩面积，这些都是降低海滩人口密度的简单直接措施。本文描述了一种简单的分析公式，用于评估海滩上静态人口密度相对于绝对最大人口密度的下降百分比。这个简单分析工具的变量是瞬时海平面（潮汐）、气温和海滩扩张。海滩扩张是该公式中唯一且可控的变量，指的是纳入一些海滩的近邻或相邻扩展区域。建议海滩扩张不仅在疫情期间非常有用，对新常态也很有帮助。本文介绍了该方法在阿根廷拉科斯塔市的应用。
