dam spillway 3d model

Using the provided reference image of a stone dam spillway, generate a highly accurate, watertight 3D model suitable for 3D printing. The model must faithfully match the proportions, massing, and architectural logic shown in the image. Model the dam as a single solid printable object with the following requirements: Accurately reproduce the overall geometry of the dam, including: The sloped stone walls on both sides The series of vertical spillway arches The top horizontal deck and parapet The stepped stone base and lower platform Complete the right side of the dam fully, ensuring it is structurally continuous and detailed, without mirroring or duplicating the left side. Subtle realistic variations in stone layout and edge detailing should be included. Simplify water elements for 3D printing: Convert flowing water into solid sculpted forms Remove thin splashes or fragile overhangs Ensure all water volumes are thick enough to print Stone texture should be engraved or embossed subtly, not photoreal
