It can be calculated using the following equation:<\/p>\n<p>$$\\text{Inlet time} = \\frac{\\text{Distance}}{\\text{Flow rate}}$$<\/p>\n<p>The distance is the overland flow from the critical point to the drain, which is 8 km. The flow rate is the difference in level divided by the hydraulic conductivity of the soil. The hydraulic conductivity of the soil is a measure of how easily water can flow through the soil. It is typically measured in meters per day.<\/p>\n<p>To calculate the inlet time, we need to know the hydraulic conductivity of the soil. However, this information is not given in the question. Therefore, we cannot calculate the inlet time exactly.
