초록
To utilize the hydraulic and hydrological models when simulating floods in agricultural watersheds, it is necessary to consider agricultural reservoirs,farmland, and farmland drainage system, which are characteristics of agricultural watersheds. However, most of them are developed individually bydifferent researchers, also, each model has a different simulation scope, so it is hard to use them integrally. As a result, there is a need to link eachhydraulic and hydrological model. Therefore, this study established an integrated flood simulation system for the comprehensive flood simulation ofagricultural reservoir watersheds. The system can be applied easily to various watersheds because historical weather data and the SSP (SharedSocio-economic Pathways) climate change scenario database of ninety weather stations were built-in. Individual hydraulic and hydrological models werecoded and coupled through Python. The system consists of multiplicative random cascade model, Clark unit hydrograph model, frequency analysismodel, HEC-5 (Hydrologic Engineering Center-5), HEC-RAS (Hydrologic Engineering Center-River Analysis System), and farmland drainage simulationmodel. In the case of external models with limitations in conceptualization, such as HEC-5 and HEC-RAS, the python interpreter approaches theoperating system and gives commands to run the models. All models except two are built based on the logical concept.
