This thesis highlights the development and analysis of multiple neutrino detectors deployed to the Spallation Neutron Source (SNS) at Oak Ridge National Laboratory as part of the COHERENT experiment. It includes a preliminary measurement of the neutrino-induced neutron cross section on lead, and analysis that led to the first inclusive electron-neutrino charged-current measurement on iodine. These results add to the small number of inelastic neutrino-nucleus cross sections measured in this...
