PDM Descriptors

Simulations using PDM functionality can only be run if the PDM option is enabled on your licence.

PDM Descriptor objects can be specified as part of the Subcatchment data and are used to define the rainfall-runoff model parameters when using a runoff surface with runoff volume type of PDM.

A particular PDM descriptor is associated with a subcatchment by selecting the PDM descriptor ID in the PDM Descriptor field of the Subcatchments Grid or in the Surface parameters section of the Subcatchment property sheet. A PDM descriptor can be associated with more than one subcatchment.

For information on PDM, see the Probability Distributed Model (PDM) topic.
