Line 203: == Do the calculations change if I specify multiple culverts using the Number_of attribute? == Yes. When using the Number_of attribute, TUFLOW/ESTRY calculates hydraulic behaviour based on the dimensions of each individual barrel, not the total combined width. This means that a single 18 m wide × 1.2 m high culvert will behave differently to ten 1.8 m wide × 1.2 m high culverts, even though the total width is the same. Differences arise due to changes in: This means that a single 18 m wide × 1.2 m high culvert will behave differently to ten 1.8 m wide × 1.2 m high culverts, even though the total width is the same. Differences arise due to changes in: * Wetted perimeter: Multiple smaller barrels create more total surface area in contact with the water, influencing friction losses.
