Celem tej pracy jest omówienie przestrzennych i krótkotrwałych zmian w morfologii plaży pod kątem grzbietów i strumieni na podstawie profili plaży w Vembar, na wybrzeżu Kallar, Tamil Nadu, Indie. Plaże składają się głównie z średniego do grubego piasku i ciężkich minerałów. Dla plaż charakterystyczne są grzbiety, strumienie i zagłębienia. Grzbiety i strumienie są niewielkie ze względu na prace kopalniane prowadzone w okolicy. Ustalono, że przestrzenne i tymczasowe zmiany w systemie grzbietów i strumieni są kontrolowane przez pianę morską/łamiące się fale. Zmiany objętości sedymentu wynikają z nieregulowanej aktywności kopalni. Erozja ma wpływ na profil wszystkich plaż, zwłaszcza strumieni. Strefy przyrostu znajdują się wyżej, to znaczy na najwyższych grzbietach i wałach plażowych. Krótkotrwałe zmiany wielkości plaży wyjaśniają zniekształcenie grzbietów i strumieni. Ma to związek z pobliską kopalnią. Zaobserwowano wzorzec wiatru wyżej plaży, gdzie warunki pozwalają na transport sedymentu piasku i jego ruch na grzbietach i strumieniach.
