Crater depth in fluid impacts
WebThe depth of the crater depends on the material properties of impactor and target, as well as the velocity of impact. Typically, greater impact velocity means greater crater depth. … Websmaller crater (19 km diameter) superimposed on the rim of the 150 km diameter crater. The area of the western basin is approximately 9,000 km2, with an average depth of 40 m and a volume of 1100 km3. Fig. 2. Detail of the southern paleo-lake basins and channels in the study area.

WebFeb 28, 2024 · When a liquid drop strikes a deep pool of a target liquid, an impact crater opens while the liquid of the drop decelerates and spreads on the surface of the crater. … WebNov 12, 2024 · The De Brouckere mean diameter (D[4,3]) was enhanced with increases in the ratio between flow depth and raindrop size (h / d; p < 0.05), indicating that more raindrop energy dissipated in deeper flows. Moreover, a greater proportion of energy was dissipated from small raindrops than from large ones with an increasing flow depth.
WebAn expanded crater is a type of secondary impact crater. Large impacts often create swarms of small secondary craters from the debris that is blasted out as a consequence of the impact. [22] Studies of a type of secondary craters, called expanded craters, have given us insights into places where abundant ice may be present in the ground.
