S\u0131cak kum \u00fczerinde a\u011f\u0131r bir cismi \u00e7ekmek kum sekileri olu\u015fturarak topra\u011f\u0131n kaz\u0131lmas\u0131na sebep olur; ki bu da ta\u015f\u0131ma i\u015flemini neredeyse imk\u00e2ns\u0131z hale getirir. Daniel Bonn ba\u015fkanl\u0131\u011f\u0131ndaki sekiz ki\u015filik ara\u015ft\u0131rmac\u0131 ekibinin \u00e7al\u0131\u015fmas\u0131nda, kuru kumda \u00e7ekilen k\u0131zaklar\u0131n \u00f6n\u00fcnde kum \u00f6beklerinin olu\u015ftu\u011funu M\u0131s\u0131rl\u0131lar\u0131n da fark etmi\u015f oldu\u011fu belirtiliyor. Bu sorunun tek \u00e7\u00f6z\u00fcm\u00fc, biriken kumu s\u00fcrekli olarak yoldan temizlemek olabilirdi ki, bu da zaten me\u015fakkatli olan s\u00fcreci daha da uzatacakt\u0131.<\/p>\n

Bununla beraber, nemli kum daha farkl\u0131 davran\u0131r. Ara\u015ft\u0131rmaya g\u00f6re, kumdaki s\u00fcrt\u00fcnme kuvveti su ekleyerek b\u00fcy\u00fck bir oranda d\u00fc\u015f\u00fcr\u00fclebilir.

Bu k\u00f6pr\u00fcler, k\u0131zaklar\u0131n kum sekileri olu\u015fturmas\u0131n\u0131 engellemekle kalmay\u0131p, ayn\u0131 zamanda k\u0131zaklar\u0131 \u00e7ekmek i\u00e7in gerekli olan g\u00fcc\u00fc de yar\u0131 yar\u0131ya azalt\u0131r. Bununla birlikte, fazla su farkl\u0131 problemler do\u011furur.
