A New Formulation of the Distributed Rainfall-Runoff Model Using Object-Oriented Modeling

Today, many kinds of rainfall-runoff model have been proposed. Those models' calculations are executed by binding hydrological elementary steps of the whole basin represented as various methods or models. As a prerequisite for using such programs, understanding specialized knowledge such as hydrology or hydraulics is needed. If user wants to add or extend the model, the programming knowledge is also required. The problem for using such program is that the user is not always experts in those fields. For example, not every water administration officials are capable as professional engineers. The purpose of this study is to formulate universal and easy incorporable integrated flood forecasting model. In this instance we are proposing the new distributed rainfall-runoff model using circuit diagram as a runoff model.
