Double‐ring infiltrometers are routinely used by turfgrass specialists, soil scientists, and other professionals to measure the infiltration rate of field sites. Measurement of infiltration rate is important in proper golf course design development and other scenarios that require estimates of runoff. This study compared several commonly performed double‐ring infiltration methods as follows: 30‐ (inner) and 60‐cm (outer) diameter rings with a constant water depth (head), 15‐ (inner) and 30‐cm (outer) diameter rings with a constant head, and 15‐ (inner) and 30‐cm (outer) diameter rings with a falling inner head. In addition, a Mariotte siphon device was fabricated to maintain a constant inner head for the 15‐cm diameter rings. The 15‐ and 30‐cm rings with the constant head resulted in significantly higher infiltration rates compared to 30‐ and 60‐cm diameter rings with a constant head and 15‐ and 30‐cm rings with a falling …
