EnergyLoss Properties

Angle in degress describing abrupt change in river alignment Type: angle Unit: [degress] Default: 0.0

Calculated Discharge derivative with DownStreamWaterLevel. Downstream is relative to the direction of chainage. The value is calculated by SetWaterLevels. Unit: [m^2/s]

Calculated Discharge derivative with UpStreamWaterLevel. Upstream is relative to the direction of chainage. The value is calculated by SetWaterLevels. Unit: [m^2/s]

Linear flow variation. For water level differences less than delhs use a linear Q variation between h1-h2=delhs and h1-h2=0. This is to avoid stability problems for small water level differences where dQdh goes to infinity. Unit: [m] Default: 0.01

Calculated Discharge. The value is calculated by SetWaterLevels. Unit: [m^3/s]

Downstream cross section data. The cross section data is the processed level, with, area.

Downstream water level.Downstream refers to the direction of chainage. The water level is set by use of SetWaterLevels Unit: [m]

Property used by (de)serializer, when it can not find proper target for a data field. Support of forward compatible data contracts.

Flow area through structure. Used by most (but not all) structures.

The discharge (and discharge derivatives) are scaled by the flow factor.

Frictionfactor used to calculate the energy loss caused by ordinary friction. Type: Dimensional factor Unit: [s2/m6] Default: 0.001

Angle in degress describing gradual change in river alignment Type: angle Unit: [degress] Default: 0.0

Value used when plotting the structue Unit: [m] Defualt: 0

Structure ID

Used to get a consistent description of the structure. The ID comes in user units. Used e.g. when reporting errors, warnings and hints.

Flag to control if the structure is implicit or explicit. If the structure is explicit (Implicit == false) then the derivatives of the dicharge are always zero. Default value: true

Invert level down stream

Invert level up stream

Length of the structure. Unit: [m] Default value: 0m

Location property.

Minimum head loss across a structure. Default value = 0.01

Energy loss coefficient for negative flow at flow contraction losses Type: Dimensional factor Unit: [] Default: 0.0

Energy loss coefficient for negative flow at flow expansion losses Type: Dimensional factor Unit: [] Default: 0.0

Energy loss coefficient for negative flow at user defined energy losses Type: Dimensional factor Unit: [] Default: 0.0

Part of the flow in a parallel strucutre that passes through this structure.

Energy loss coefficient for positive flow at flow contraction losses Type: Dimensional factor Unit: [] Default: 0.0

Energy loss coefficient for positive flow at flow expansion losses Type: Dimensional factor Unit: [] Default: 0.0

Energy loss coefficient for positive flow at user defined energy losses Type: Dimensional factor Unit: [] Default: 0.0

Roughness for gradual change in river alignment Type: Dimensional factor Unit: [] Default: 0.0

The getter is used to get a list of errors.

Bank side that side-structure is located on

If side structure contains reservoir, and has the Coordinate set, this is not used (and should be set to Undefined).

Reservoir at end of side structure. Null if not side structure, or no reservoir is defined

Structure cross section data. The cross section data is the processed level, with, area.

Type of structure

String used to identified cross sections

Structure type, unique for each structure.

Upstream cross section data. The cross section data is the processed level, with, area.

Upstream water level. Upstream refers to the direction of chainage. The water level is set by use of SetWaterLevels Unit: [m]

Flag telling if there is energy loss due to an abrupt change in river alingment Type: boolean Default: false

Flag telling if there is an energy loss due to a contraction Type: boolean Default: false

Flag telling if there is an energy loss due to a expansion Type: boolean Default: false

Flag telling if there is energy loss due to a gradual change in river alingment Type: boolean Default: false

Flag telling if there is an user defined energy loss Type: boolean Default: false
