Abstract : The term "infiltration" refers to the process of water moving in all directions into the soil. The maximum rate at which water is absorbed into the soil at any given time is known as the infiltration rate. The rate of infiltration is measured in centimetres per hour (cm/hr) or millimetres per hour (mm/hr). Before the building can be built, the soil must be stabilized if it has a low infiltration capacity. The lifespan of a building is reduced if water remains stagnant at ground level. As a result, determining the rate of infiltration is critical. This paper makes an attempt to look into infiltrometers and models that are best for determining infiltration rate. The Kostiakov model, Horton model, Philips model, Green-Ampt model, Regression model, M5P model, Modified Kostiakov model, and Branched Modified Kostiakov model were all used by the significant proportion of the authors. The results show that the Kostiakov and Horton models were both effective in estimating the infiltration rate.
