Use of liquid analog model in engineering hydrology training (precipitation-runoff model)

Abstract

Proper training of hydrologists in the field of precipitation-runoff modeling can play a significant role in overcoming many flood problems. In this paper, after introducing the liquid analog model, it is established as a new analog model in the field of hydrology and based on the linear reservoir model. Its scale and laboratory construction are presented, and then how it is used to simulate the Nash precipitation model for a real basin. The effect of basin shape on the output hydrograph as well as the effect of precipitation direction on basin response has been investigated separately. The results of the experiments performed with the model indicate that the model is suitable in this field. Due to the simple structure, ease of use and visual quality of the model, this model can be a suitable teaching aid tool in the field of precipitation-runoff modeling training.
