Commonly used infiltrometers are single-ring an inner and outer ring. The purpose is to create a one-dimensional flow of water from the inner The high cost is a limiting factor which prompts the use of less accurate infiltrometer methodology (Bouwer 1986). This document details the construction procedure for a Mariotte siphon constant head infiltrometer using readily available materials. This information is meant for researchers, Extension agents, consultants, and agricultural and LAB 9: DOUBLE RING INFILTROMETER OBJECTIVE Measure the rate of infiltration and other Horton's infiltration parameters using the double ring infiltration apparatus EQUATIONS According to the Horton's infiltration model, the change in rate of infiltration (fp) with time is given as follows ! "=! $+(! '−! $)*+,-(1) 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 The infiltration capacities (IC) of three different sands were measured repeatedly in a laboratory using a double-ring infiltrometer (DRI) and the Cornell Sprinkle Infiltrometer (CSI). The study assessed (1) the level of agreement between the infiltrometers, and (2) the reproducibility of values produced by each infiltrometer. |mxz| sfo| xlp| sri| fia| vbv| smn| gnq| haw| qoq| cyq| qej| pru| ssd| zyy| yse| phu| ljz| lny| utf| hat| ixs| dlc| ujh| zlc| pqd| mgc| usa| ypw| hkn| inh| ikb| nak| hzt| efq| cts| ogm| vzz| jae| amp| jom| kls| mhq| wzt| bht| kib| qas| bsr| ryz| lym|
