An overland diversion is a special type of link object shown in a network as a dashed line.

Primary Overflow Path

The primary overflow path may be the next downstream pit in the network or it may be any other pit in the network. This path represents the preferred or priority direction of flooded node flows.

Primary Overflow Characteristics

These are the characteristics applying to the designated primary overflow path.

• Flow Threshold)
• Flow (m³/s, ft³/s reached in primary path before any diversion occurs.

% of Surcharge above Threshold

Fraction of flow above threshold that continues to flow down the primary flow path.
