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.

I need help on this hydraulic problem. Thank you Derive an expression for the critical hydraulic head for which a column of saturated sediments with the thickness H will reach ‘quicksand conditions’ (i.e., the effective vertical stress is zero). For simplicity, assume that the water table is at the sediment surface. Once you derive the formula, calculate how fast groundwater must flow upward to reach the quicksand conditions assuming a range of hydraulic conductivities characteristic for fine-grained sands (between 10^-7 and 10^-4 m/s). Assume that the saturated density of sands is 2,000 kg/m^3.
