SPT tests were carried out in the silty sand layer at 3 m, 9 m and 12 m depths from the ground surface. Energy ratio has been accepted as 60%. The number of strokes for the experiment are listed below. Groundwater level is 2 m below ground level. Dry and water-saturated unit volume weights of the soil were determined as 18 kN / m3 and 19 kN / m3, respectively. Depth from the surface, (m)         SPT-N60 3                                                          4-6-8 9                                                        7 -9-11 12                                                      10-11-13   Which of the following is the corrected (N1) 60 value at a depth of 12 meters

Groundwater Flow

The term groundwater refers to the water which is found beneath the earth's surface. Pores present in the soil and rocks with fractures make a passage for rainwater to enter the earth's surface and deposit as groundwater. The flow nature and direction of groundwater under the earth's surface directly impacts the strength and compressibility of the soil, which reflects its ability to support structural loads.
