The paper aimed to explore the morphometry of the plunge pool and retreat mechanism of the waterfalls with the help of an empirical study of Turga Waterfall of Ajodhya Hill, Purulia, West Bengal, India. To explore the morphology of waterfall and its plunge pool, width (w), average depth (d), the maximum depth (\(d_{{{\text{max}}}} )\), bathymetric study of plunge pool, and fall height or drop height \({ }(D_{{\text{h}}} ),\) the distance of jet impingement from the present headwall \({ }(X_{{\text{n}}} )\) was recorded from Turga Waterfalls. The magnitude of \(d_{{{\text{max}}}}\) and \(X_{{\text{n}}}\) is proportional to \(D_{{\text{h}}}\). The presence of a series of successive plunge pools at different elevations intermittent by step-like headwalls suggests gradual continuous vertical drilling of successive plunge pools as a more efficient waterfall retreat mechanism in the homogenous massive rock mass.

暴跌水池的形态和瀑布的退缩机制

本文旨在通过对印度西孟加拉邦普鲁利亚Ajodhya Hill的Turga瀑布的实证研究,探索瀑布的形态和瀑布的后退机理。要探索瀑布及其瀑布池的形态,宽度(w),平均深度(d),最大深度(\(d _ {{{\ text {max}}}}} \)\,瀑布池的水深研究,下降高度或下降高度\({}(D _ {{\ text {h}}}),\)射流撞击到当前端壁的距离\({}(X _ {{\ text {n}}}) \)来自Turga Waterfalls。的大小\(d _ {{{\文本{MAX}}}} \)\(X _ {{\文本{N}}} \)正比于\(d _ {{\文本{H}}} \ )。在阶梯状端壁间断的不同高度处,一系列连续的冲积池的存在表明,连续冲积池的逐步连续垂直钻探是一种在均质块状岩体中更有效的瀑布消退机制。
