A 500-m long levee made of compacted clay impounds water in a reservoir as shown in Figure 1. There is a 1-m thick (measured in the direction perpendicular to the seam) sand seam continuing along the entire length of the levee at a 10° inclination to the horizontal, which connects the reservoir and the ditch. The hydraulic conductivity of the sand is 2.6 × 10–3 cm/s. Determine the volume of water that flows into the ditch every day
