English term or phrase: blowout
Definition from geotech.org:
A shallow circular or elliptical depression in sand or dry soil formed by wind erosion.

Example sentence(s):
  • Deflation basins, called blowouts, are hollows formed by the removal of particles by wind. Blowouts are generally small, but may be up to several kilometers in diameter. cartage.org
  • Slopes protected from the prevailing winds have had negligible wind erosion except in areas where severe erosion created deflation basins. These blowout basins are limited to small interfluve areas, a few square miles in size, which probably had a thick layer of loose, sand-size fissile-shale fragments that winds could erode. Soil Science Society of America
  • Wind erosion removes and redistributes soil. Small blowout areas may be associated with adjacent areas of deposition at the base of plants or behind obstacles, such as rocks, shrubs, fence rows, and roadbanks. United States Department of Agriculture

風蝕窪地


Definition from 地理教師手冊:
乾燥區域地面或砂丘地帶,因風吹蝕而成的巨大窪地稱之,又稱吹蝕穴。如埃及開羅以西的夸塔拉(Qatlara)窪地,長320公里,最低處在海平面以下134公尺。這些風蝕窪地的底部,因接近地下水面,土壤濕潤,成為肥沃的沙漠綠洲。

Example sentence(s):
  • 挟沙气流磨蚀地面,地面出现风蚀沟槽。磨蚀作用进一步发展,沟槽扩展为风蚀洼地;洼地之间的地面相对高起,成为风蚀土墩。 - 百度  
  • 當氣流沿風口入侵,使風蝕窪地加長、加深,甚至吹蝕成拋物線形沙丘。 - 臺灣大學地理環境資源學系  
  • 较深的风蚀洼地如以后有地下水溢出或可以存储雨水即成为干燥区的湖泊,如中国呼伦贝尔。 - 少年维基百科
