Analysis and Modeling of Free-Surface Flows in a Prismatic Channel in an Experimental Environment
Synopsis
Algeria is one of the countries with arid and semi-arid climates, characterized by very cold winters and very hot summers. Precipitation in this type of climate generally leads to torrential flows, causing significant sediment transport in the mobile beds of natural watercourses and also very important floods either in natural environments or in cities. This study focuses on natural flows but through laboratory modeling in a prismatic channel with constant dimensions and roughness coefficients to better clarify and approach natural free-surface flows. In this experiment, we calculated the Chézy and Manning coefficients and inferred whether they are influenced by changes in parameters characterizing the channels such as flow slope and flow velocity.
