SpillingCover Class |
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.

public class SpillingCover : Cover, ISpillingCover, ICover
The SpillingCover type exposes the following members.
Constructors| Name | Description | |
|---|---|---|
 | SpillingCover |
Default constructor

Properties| Name | Description | |

 | ExpansionCoefficient |
The surface area of normal and spilling covers expand to this coefficient times the
area at the start of the cover.

| SpillingWaterLevel |
Water level where spilling starts. Usually ground level. Observe: Cover expansion starts at a different level
than spilling.
Unit: [m]
