The tidal waves scattered by a small island and a small cape of elliptical shape are derived by the method of matched asymptotics. The results complement the irrotational flow approximation of the near field by Proudman (Proc. Lond. Math. Soc., vol. 14, 1915, pp. 89–102). The potential for harnessing tidal power is assessed for the limiting case of a coast-connected thin dam.

小岛或海角的潮汐衍射，沿海屏障的潮汐力

通过匹配渐近法得到由小岛和椭圆形小海角散射的海浪。结果补充了Proudman（Proc。Lond。Math。Soc 。，第14卷，1915年，第89-102页）对近场的非旋流近似。对于沿海连接的薄水坝的极限情况，评估了利用潮汐能的潜力。
