Résumé
Various models have been applied in the analysis of hydrologic conditions in different watershed areas. The whole spectrum of models available as tools for natural resource managers is because the use of modeling techniques are limited for specific areas and/or purposes. Constraints and limitations have to be realized in order to properly select a model that answers the needs of a certain locality, for a stated goal. It is the purpose of this paper to review existing hydrologic models, and in the process, select the most promising for application in the southwestern part of Saudi Arabia for the purpose of designing flood control and warning systems. The six models under investigation are the SCS Method, SCS TR-20, Stanford, USDA HL-74, HEC-1 and ANSWERS. Based on the scope and limitations of each model, as well as certain restrictions found within the area of study, it became evident that the SCS models are the most appropriate. This became more apparent having considered the type of data input the models require that can be provided for in the study area, as well as the simplicity of the models and scale of application.
