AB We present a complete study of the multiparticle biased diffusion-limited aggregation ~MBDLA! modelsupplemented with surface diffusion ~SD!, focusing on the relevance and effects of the latter transport mechanism.By comparing different algorithms, we show that MBDLA 1 SD is a very good qualitative model forelectrodeposition in essentially the whole range of current intensities provided one introduces SD in the modelin the proper fashion. We have found that the correct procedure involves simultaneous bulk diffusion and SD,introducing a time scale arising from the ratio of the rates of the two processes. We discuss in detail thedifferent morphologies obtained and compare them to the available experimental data with very satisfactoryresults. We also characterize the aggregates thus obtained by means of the dynamic scaling exponents of theinterface height, allowing us to distinguish several regimes in the mentioned interface growth. Our asymptoticscaling exponents are again in good agreement with recent experiments. We conclude by discussing a globalpicture of the influence and consequences of SD in electrodeposition
