| Nodes | Class implementing a list of INode's Required for generic list COM interop |
| NormalCover | If the water level in a manhole or a basin reaches the ground level, an artificial “inundation” basin is inserted above the node. The surface area of this basin is gradually (over one meter) increased from the area in the manhole or the basin to a 1000 times larger area, thus simulating the surface inundation. The maximum level of inundation is 10 meter above the specified ground level. When the outflow from the node surmounts the inflow, the water stored in the inundation basin re-enters the system. When the water level in the node increases and is above ground level, the following is assumed: During a time step the surface area in the basin is calculated using the water level from the start of the actual time step. A situation like this is shown in Figure 8.1. If the water level passes through the transition region between the actual manhole or structure and the artificial basin, this assumption leads to generation of water. In Figure 8.1 the shaded area illustrates the generated volume of water. Figure 8.1 Simulation of the surface flooding When the increase of the water level during a time step is relatively small, then the generated water volume is negligible. If the water level is changing rapidly, the generated volume of water is important and due to that an appropriate correction is built in the program to ensure no generation of water. |
| Outlet |
An Outlet is a volume free node where water flows out of the system.
An outlet is the only type of open boundary that does not need a boundary condition An outlet can have a boundary condition (water level/QH), in which case the water can also flow into the system. The IOutlet extends the IVolumeNode, though it can also be used outside a sewer system, in which case the GroundLevel is set to the BottomLevel. The rest of the IVolumeNode properties are not valid for a non-sewer outlet. |
| OutletHeadLoss | Description of headloss from node outlets |
| Reach | Base class for Link and Branch |
| Reaches | Class implementing a list of IReach's Required for generic list COM interop |
| ReachJunction | This is a special kind of junction nodes, specifying a Location on a reach. The XCoordinate and YCoordinate is only used for visualization purposes and should be defined at or near the location on the reach. |

| RoutingReach | A reach where water is routed through, using one or several IRoutingElement's. |
| SealedCover | Any manhole or basin can be defined as 'sealed'. If a node is defined as a sealed node, then the maximum water level at a node is set to the ground surface. In this case, the pressure will rise without any water on the ground surface. The following relations are valid: Hm=Pm for Pm SmallerOrEqual Htop (8.1) and Hm=HTop fopr where: Hm is the water level in the node [m], Pm is the pressure level in the node [m], Htop is the ground level for the node [m]. |
| SewerJunction | A sewer junction is connecting to two or more sewer links |
| SewerNode | A SewerNode includes cover functionality to a Node |
| SpillingCover | Any manhole or basin can be defined as 'spilling'. If the water level in a node defined as a spilling node reaches the ground level, the water will start spilling irreversibly out of the system. The flow will be computed using the free overflow formula, according to the following: for Hm SmallerOrEqualTo Htop+deltaP (8.2) Qspill = 0 for Hm LargerThan Htop+deltaP (8.2) Qspill = Relative Weir Coefficient*0.63*B*sqrt(2g)*(Hm-(Htop+deltaP))^1.5 here: Qspill= the spill discharge [m3/s], B = a conceptual spill width [m], Hm = the water level in the manhole [m], Htop = the ground level in the manhole [m], deltaP = the "Buffer Pressure Level" for the spill [m], g = the acceleration of gravity [ms-2), RelativeWeirCoefficient = the linear scaling coefficient for the spill. |
| StructureOutlet | Special kind of outlet: When a structure is discharging directly out of the system, and no outlet has been explicitly specified, the engine will put in a StuctureOutlet downstream of the structure. |
| StructureReach |
A structure reach is an "artificial" reach containing
one structure and no volume. It the reach has a length,
it is an "artificial" length.
A structure reach is used for two common scenarios: a structure in a node, and a structure between the main river and the side river (link channel). A structure in a node is modelled by defining two nodes with a structure reach in between. |
| VolumeNode | A volume node is a node with volume that has a physical interpretation in the real world. |
| IBasin | A Basin is a generalization of a IManhole, it can have any shape, the geometry is defined through the BasinGeometry. |
| ICatchmentConnection | Interface for information on where a specific catchment is connected in the network, and the area of the catchment that goes into that part of the network. The connection in the network is here defined by a ReachId and and up- and down-stream chainage. If the two chainages are the same, the connection is a point connection, otherwise it is a span (distributed) connection. |
| ICatchmentConnections | Interface for a list of ICatchmentConnection's Required for generic list COM interop |
| ICover | A cover can be put on top of a volume/sewer node, as e.g. a manhole, set at Cover |
| IDisplaceableCover | A type of spilling cover, where water spills out of the network model but the size of the opening can change due to pressure of water column. |
| ILeapingWeir |
A leaping weir is a junction node which connects three reaches.
The third reach is connected through a bottom opening, named
a Leaping Weir. If the water runs fast, the water may leap
over the weir, i.e. the speed of the water will effect
the flow through the weir.
The weir is characterised by a length (WeirLength) and a width (WeirWidth). Based on the article of Oliveto, Giuseppe. (1998). "Sewerage overflows: new researches on bottom openings and side weirs". Excerpta. 12. 251-281. |
| IManhole | A Manhole is a sewer node where network reaches join. It includes a diameter and a cover. |
| INetwork | Defines a 1D network, nodes and reaches. |
| INode |
Interface that is implemented by all node types. That is all nodes has ID and coordinates.
The most basic node, the junction node used in river junctions, implements this interface. Note that junction nodes are automatically created for reach connections that are based on locations, so there will be more junction nodes than actual INodes defined here. |
| INodes | Interface for a list of INode's Required for generic list COM interop |
| INormalCover | Normal cover, see NormalCover |
| IOutlet |
An Outlet is a volume free node where water flows out of the system.
An outlet is the only type of open boundary that does not need a boundary condition An outlet can have a boundary condition (water level/QH), in which case the water can also flow into the system. The IOutlet extends the IVolumeNode, though it can also be used outside a sewer system, in which case the GroundLevel is set to the BottomLevel. The rest of the IVolumeNode properties are not valid for a non-sewer outlet. |
| IReach |
A Reach is a generalization of the link and branch concepts from sewer and river models.
Specification of connection as 'start' and 'end' does not have any impact on the computations, apart that positive flow is considered from start to end. Therefore, it is recommended to specify the start-end in the direction of predominant flows, or to set the ReverseDirection flag. The type of the reach is specified by the cross section for that reach. It may take the form of one of the 'standard' pipes (Circular, Rectangular, O Shaped, Egg-Shaped), or any closed or open cross section shape (CRS/Natural Channels). The LocationSpan defines the geographical position of the reach. Typical types of reaches are the sewer link and the river branch. A sewer link is featured by:
