Analytical Solution of Dam Break Wave with Flow Resistance: Application to Tsunami Surges

摘要: Surge waves resulting from dam breaks have been responsible for numerous losses of life. Related situations include flash floods, debris flow surges, surging in the swash zone, and tsunami surges on dry coastal plains. Herein break wave is analysed as a tip region where resistance dominant, followed by an ideal-fluid inertial effects gravity are dominant. The analytical development yields explicit expression instantaneous free-surface profile properties that compare well with well-known experimental data. Results then applied to plains, compared some data set. present offers simple expressions both more advanced theoretical solutions, further well-suited pedagogical purposes computational model validation.
