ABSTRACT
This chapter discusses the applications of personal computer graphics in Storm Water Management Model (SWMM) modeling. The graphics provide the modeler with more efficient and cost effective analysis, planning, design, and management tools. The proposed technique requires developing graphical user interfaces (GUI) for SWMM. SWMM is a large and complex model which simulates the movement of precipitation and pollutants from the ground surface through pipe and channel networks, storage treatment units and finally to receiving waters. A GUI is a computer program which acts as an interpreter between the user and a computer. The GUI replaces difficult-toremember text commands by interactive computer graphics consisting of menus, dialog boxes, input and output windows, and icons. The utility programs aid the development and execution of SWMM models. In the past, the main argument against using continuous SWMM modeling has been the difficulty of managing large amounts of input and output data.
