An infiltration apparatus is disclosed herein. In various aspects, the infiltrometer apparatus includes a cylinder that defines a cylinder passage coupleable to a base that defines a base passage to form an infiltrometer passage. The infiltrometer apparatus includes a baffle removably emplacable within the infiltrometer passage, in various aspects. The baffle is in gapped relation with a soil surface of a soil when the base coupled to the cylinder is inserted into the soil and the baffle is emplaced within the infiltrometer passage, in various aspects. In various aspects, the infiltrometer apparatus includes a level detector to detect a water surface level of a water surface within the infiltrometer passage. The level detector may communicate by network with a computer to communicate data indicative of the water surface level to the computer. Related methods of use of the infiltrometer apparatus are also disclosed herein.
