Design and Performance Evaluation of Constant Head Double Ring Infiltrometer at H.S.T.U.

Abstract

An indication of soil that allows water to penetrate into the soil profile is infiltration. Increased ground water recharge is aided by increased filtering rate. The purpose of this study was to assess the soils' infiltration qualities in H.S.T.U. With a constant water head double ring infiltrometer with inner ring of 15 cm, outer ring of 30 cm, and a height of 27 cm was designed. To assess soil texture class, electrical conductivity, pH, and moisture content, soil samples were taken using an auger at a depth ranging from 0 to 15 cm from 5 different chosen locations. Infiltration rates were discovered utilizing a constant head double ring infiltrometer to be 17.53 mm/hr, 13.53 mm/hr, 21.34 mm/hr, 22.4 mm/hr, and 16.21 mm/hr. Sand was present in proportions of 61.2%, 54.2%, 63.2%, 67.2%, and 55.2%. The highest percentage of sand was discovered in location L-4. The percentage of silt was found 26.4%, 26.4%, 20.4%, 22.4% and 34.4% accordingly. 12.4%, 14.4%, 11.4%, 10.4%, and 10.4% of the total weight was clay, respectively. The percentage of water content in soil at five different places was 14.74%, 14.12%, 14.62%, 8.62%, and 11.6%, respectively. The findings show that the research field contains the highest percentage of sand and that the penetration rate is also the highest there. Also, showed a proportionate association between infiltration rate and percentage of sand and a negatively proportional relationship with silt, clay particles, and soil moisture content. The average soil infiltration rate for the HSTU campus area was 18.202 mm/hr.
