WebSep 9, 2024 · Soil permeability was determined at a depth between 50 and 70 cm using the Porchet method (Porchet and Laferre 1935). Porchet’s method consists of the following: as a function of time, the infiltration of a quantity of water poured into the auger hole (De Beaucorps et al. 1987) (Fig. 2). WebApr 25, 2024 · To ensure uniform coverage inside the infiltration area, we steadily moved the hose during each infiltration; no standing water surface was created indicating that the injection rate was lower than the infiltration capacity of the soil (approximately 18 mm/h, measured during several tests using the Porchet method). The first two infiltration ...

WebThe test is repeated two more times in succession and the rate at which the water level falls in the third test is used as the infiltration rate. Measured percolation rate shall be converted to an infiltration rate using the Porchet method (Appendix D.3.4). This test has the advantage of being inexpensive to conduct. Web14 measurements of the infiltration rate of water in the soil by the Porchet method were carried out 15 in sixteen sites. Finally, soil samples taken by auger and core sampling were studied in the 16 laboratory. Physico-chemical parameters such as grain size, porosity, moisture, pH, 17 compactness and organic matter were determined. smart led monitor
