WebA new semi-analytical algorithm for generating the local groundwater velocity field within irregular three-dimensional grid cells (such as a Voronoi cell) is presented. The method supports particle tracking in the MODFLOW-USG software package for a variety of supported unstructured grid formats. It … WebMODFLOW In MODFLOW, stress periods are used to define time intervals during which the inputs for the model remain constant. For example, if the pumping rate on a well were to change on a monthly basis, the stress periods would need to be one month in length or less. messner inc
