Usinga simple model potential, we study the effects of weakMarkovian dissipation on the quantum arrival time. The interaction withthe environment is incorporated into the dynamics through a Markovianmaster equation of Lindblad type, which allows us to comparetime-of-arrival distributions and approximate crossing probabilities for different dissipation strengthsand temperatures. We also establish a connection to an earlierstudy where quantum tunneling with dissipation was investigated, which leadsus to some conclusions concerning the formulation of the continuityequation in the Lindblad theory.
