本年度以屏東縣為計畫區，將現行淹水潛勢模擬之數值模式，進行地文資料之強化更新與各項參數之細緻檢校，以供未來即時淹水模擬演算技術研發與下階段淹水潛勢圖繪製之所需。

From 2014 to 2016, Water Resources Planning Institute, Water Resources Agency, Ministry of Economic Affairs has established the whole Taiwan inundation numerical model Based on SOBEK mode year by year. "Second Upgrading Potential Inundation Maps " program for whole Taiwan area has been completed in the end of 2016. However, the numerical model established contains large physiographic and hydrological data, Such as the physiographic information of river, drainage systems, rainwater sewer, bridge, pumping station, gate, detention pool, and the hydrological information of the catchment , area, slope, CN value and the corresponding land use. With the completion of the hydraulic engineering project, then the establishment of the two-dimensional inundation model is gradually different from the present situation. In order to maintain the correctness of the basic data of the model and ensure the reliability of the model simulations, the observation and the field investigation of cross sections and the information of Hydraulic structures should be updated regularly. The parameters of SOBEK mode should be refined and decrease the simulation time to facilitate the subsequent development of two-dimensional real-time inundation simulation forecast. It also can research other value-added applications (such as innundation rainfall alert values),and be prepared for "Third Upgrading Potential Inundation Maps". The planning regions is Pingtung County. This plan will according to the contents of the "Second Upgrading Potential Inundation Maps of Pingtung County" (2014) to carry on the update and the modification. The plan is conducted in three phases. The first phase: supplementary information to the survey and update, including the field investigation and update of physiographic information, the catchment range delineated and the physiographic data review and update. The second stage: the numerical model refinement and update, including inundation numerical model update, establish HEC-HMS mode. The third stage: value-added application research, including rainfall alert value, and the current situation probable inundation positions and the probable reason of inundation.
