| Sumario: | The need to find a model that describes the process of water infiltration into the soil which could be more closer to the reality is extremely important, especially considering the physical characteristics of a soil has, because a better understanding of this process is of fundamental importance for the efficient management of soil and water in agricultural crops. This study aims to validate the model of Green-Ampt in a rice-growing area. The experiment was conducted in the experimental site of Paraíso do Sul - RS, where soil samples were collected for physical analysis and used the double ring infiltrometer to obtain the values of cumulative infiltration. The results obtained through the Green-Ampt model did not generate acceptable results for application. With the development of the work, it was concluded that for the implementation of Green-Ampt model it is necessary to find a new parameter setting proposal that can describe the process of infiltration to the soil type studied. |
