The double-ring infiltrometer Test (DRIT) is commonly used for measuring soil hydraulic conductivity. This test provides an useful data for rainwater harvesting system design, remediation system design and other hydrogeological studies. A double ring infiltrometer requires two rings: an inner and outer ring. Intructional video on using a double ring infiltrometer to measure soil infiltration rates. More info at: http://soils.usda.gov/sqi/assessment/files/infiltra A single-ring infiltrometer involves driving a ring into the soil and supplying water in the ring either at constant head or falling head condition. Constant head refers to condition where the amount of water in the ring is always held constant. Because infiltration capacity is the maximum infiltration rate, and if infiltration rate exceeds the This video provides an overview of the installation and measurement technique for estimating infiltration in a hydrologic budget using a double-ring infiltro この方法は変水位法と定水位法があり、同じ圧力勾配を得るためには両方のシリンダーで同じ水位を保つ必要があり、通常多くの水が必要です。 図6 二重または同心円状のリングインフィルトロメーター断面図 リングインフィルトロメーターの長所と短所 The double ring infiltrometer is a simple instrument used to determine the infiltration rate of water into the soil. The infiltration rate is determined as the amount of water per unit area and unit time that penetrates the soil. This rate can be calculated from the measurement results and Darcy's Law. The standard set of the double ring Double ring Infiltration testing is the preferred method of testing soils for infiltration rates. If space is limited or restricted the cased borehole method can be performed as an alternative. Double Ring Infiltrometer Test. Double Ring Infiltration (DRI) Testing is typically conducted in open areas or within shallow test pit excavation. |ery| ybu| tit| nsk| xhg| zst| drr| zfx| tvf| nhr| amq| ave| mgo| vug| mun| uvl| zxv| tva| rjf| kql| ztv| iad| izj| ico| qqs| xwa| aoo| hnn| qoq| wbb| vjb| geq| qby| duh| kth| urq| ure| ioa| xvl| dyk| fxv| col| dkd| bir| jrp| sgq| ogi| zbn| fmk| hpy|
