Due to geological characteristic and high rainfall, soil erosion is generally quite serious in Taiwan. The fine soil particles were eroded easily and the gravel content in soil increased gradually. Natural disaster may change soil structure. It will affect the water movement in the soil and modify soil saturated hydraulic conductivity.
Red soil sample with six treatments, namely, 0%, 5%, 15%, 30%, 45%, and 60% of gravel in soil column and delaminated the soil to three levels with the same steps, then packed it to measure soil saturated hydraulic conductivity by applying constant-head apparatus.
Experimental results indicated that, bulk density increased with increasing soil gravel content. There less than 0.05 was considered significant when gravel content in 0%~15%, so the study were not to discuss this part. No matter uniform or layering distribution got 0.05 significant when gravel content in 15%~60%. Therefore, soil saturated hydraulic conductivity decreased when gravel content in soil increased.
