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.

In this paper, the nonlinear-non-elastic behavior of the braced frames of the SCBF Special Center is compared with the BRBF anti-arc bracing brackets. Different structures with different numbers of floors, which were previously designed according to the existing regulations and the recommended behavior coefficient, were non-linear static analysis by OPENSEES software and their load-bearing and cyclic behavior were determined for both types of braces. The effect of stiffness strain percentage and the degree of initial geometric defect of the brace on the behavior of the structures were also investigated. Comparison of results indicates more formable and stable behavior of anti-buckling brace than normal brace. Also, the effect of primary geometric defect is significant only in the initial steps of displacement and the higher the percentage of strain strain strain, the more stable behavior structure against larger forces. it shows.
