Solids Builder - SWMM Nodes - Reservoir

Storage units (Reservoirs) are drain system nodes that provide storage volume.

When you want to define a device as a reservoir, you must add the tool Reservoir to the Constructor.

When adding the tool Reservoir, fill in your properties, in the tool's properties frame:

• Identification
  • Name - name of the activity
    The point name must follow the naming rules
  • Description - when the name of the activity is not enough to give context to the activity, use the description field
• Loss of Infiltration
  • Hydraulic Conductivity - Hydraulic Conductivity for fully saturated soil
  • Initial Deficit - Fraction of soil volume that is initially dry
  • Suction Potential - Mean capillary suction value of the soil along the wetting front
• SWMM
  • Bottom Elevation - Elevation of the bottom of the node (radier elevation)
    It must be associated with the property of the constructor that manages the device's Sump Elevation, for example:
    
    
  • Initial Depth - Initial depth of water in the storage unit at the start of the simulation
  • Maximum Depth - Maximum depth of the storage unit
  • Depth Overload - Additional water depth beyond the maximum allowable depth before the junction floods
• Storage Type
  • Storage Type - Method for describing how the surface area of the storage unit varies with water depth
    It can be of two types:
    1. Tabular - Describes the surface area of the storage unit varying with depth in a curve
       • Storage Curve - Name of the storage curve that contains the relationship between surface area and storage depth
    2. Functional - Describes the surface area of the storage unit varying with water depth by the relationship: Area = A * Depth ^ B + C
       • Coefficient - A value in the functional relationship between surface area and storage depth
       • Constant - C value in the functional relationship between surface area and storage depth.
       • Exponent - B value in the functional relationship between surface area and storage depth.
    3. Cylindrical - Storage unit has vertical sides and an elliptical base
       The surface area equation is:
       
       Area = (π / 4) * ( L * W )
       Where:
       L = length of the main axis of the base
       W = width of the minor axis of the base
    4. Conical -The storage unit is shaped like a truncated elliptical cone
       The surface area equation is:
       
       Area = π * ( L * W / 4 + W * Z * Depth + (W / L) * (Z * Depth)^2 )
       Where:
       L = length of the main axis of the base
       W = width of the minor axis of the base
       Z = lateral slope (horizontal : vertical) of a vertical slice through the principal axis
    5. Parabolic -The storage unit is shaped like an elliptical paraboloid
       The surface area equation is:
       
       Area = (π / 4) * ( L * W / H) * Depth
       
       Where:
       L = length of the major axis at height H
       W = width of the minor axis at height H
       H = height
    6. Pyramid -This is for storage units in the shape of a truncated rectangular pyramid or rectangular box
       The surface area equation is:
       
       Area = L * W + 2 * (L + W) * Z * Depth +(2 * Z * Depth)^2
       Where:
       L = base length
       W = base width
       Z = side slope (horizontal/vertical) (which would be 0 for a box)

The device does not necessarily need to model the entire device, also because the reservoir may have an irregular geometry if it depends on the topography. In this case, model the water intake, providing bottom elevation, overburden and depth data
