The model developed specifically for the purpose, ViaPop, is an individual-based model with the potential to understand the relative effects of different population parameters (ie sensitivity analysis) at greater depth and sophistication than an off-the-shelf package. Population parameters were determined directly from the data on the relatively well-studied north Norfolk colonies coupled with estimates of some parameters from the literature, with estimates of survival rate determined by a specific analysis of British Trust for Ornithology ring recovery data. A project board of experts in the field approved the use of the different parameters used in ViaPop. The analysis was presented as suplementary information to the environmental statement.

Mortality and fecundity parameters are allocated to individuals from Gaussian distributions. Mortality rates are age-class specific, with two age classes specified ie adults and juveniles (incorporating juveniles of age 0 and immature birds to age <3) allowing for higher rates to be specified in pre-reproductive individuals. In the basic model, the background mortality rate for adults (in the absence of wind farm collisions or natural catastrophes) expressed as the mean likelihood of survival for adult individuals in any given year is 0.90, with a standard deviation of 0.01. For juveniles, background survival rate is 0.77 with a standard deviation of 0.02. Both values were derived by Robinson (2008).
