The falling head permeameter method is a laboratory technique used to measure the hydraulic conductivity of soils by observing the rate at which water level decreases in a standpipe connected to a soil sample. This method relies on a head difference that drives water flow through the soil, allowing researchers to calculate how easily water can move through it. Understanding this method is crucial for assessing soil water retention and determining how well soil can transmit water, which impacts various hydrological processes.
congrats on reading the definition of falling head permeameter method. now let's actually learn it.
