The P8 (Program for Predicting Pollution Particle Passage through Pits, Puddles, and Ponds) Urban Catchment Model is a physically-based stormwater quantity/quality model. P8 predicts the generation and transport of stormwater runoff and associated pollutants from urban watersheds and predicts runoff and pollutant removal at user defined stormwater BMPs through the processes of sedimentation, filtration, and infiltration. The model simulates runoff and pollutant transport for a maximum of 250 watersheds, 75 stormwater best management practices (BMPs), 5 particle sizes classes (including soluble fraction), and 10 water quality components. The model simulates pollutant transport and removal in a variety of BMPs including swales, buffer strips, detention ponds (dry, wet and extended), flow splitters, infiltration basins, filtration basins, street sweeping, and user defined “General” devices. Model simulations can be run for a long duration (e.g., 50 years) and require inputs such as continuous, hourly rainfall and daily temperature data, and inputs related to particulate and pollutant loading. An extensive user interface providing interactive operation, spreadsheet-like menus, help screens and high resolution graphics facilitate model use.
