description: The interstellar medium (ISM) of the Milky Way is in a constant state of motion. Between the large scale motions of galactic dynamics and the turbulence within giant molecular clouds (GMCs), the evolution of the ISM is guided by its underlying motions. The large scale dynamics perturb the diffuse warm neutral medium (WNM) of the Milky Way, starting the cascade of the formation of clouds and stars.   In this thesis we make use of hydrodynamical simulations to explore the impact dynamics has on various quantities. The first part of this thesis focuses on the collisions of giant molecular clouds, exploring how star formation rates change with collisions. We verify the stabilitiy of "clumps" within our simulations and relating these properties to the alignment of the magnetic and velocity fields within our simulations.  The second part of this thesis zooms out, looking at the structure of the Milky Way itself. We present a new, realistic model for the gravitational potential of the Milky Way and test out how reliable the axisymmetric assumption is when used in kinematic distance estimates.
