河域至海岸環境時空變遷系統及尖端觀測網
(Observing changes from the river to the sea, OCHRE)
Observing changes from the river to the sea (OCHRE) is an integrated monitoring system established to improve Taiwan's social resilience under urgent climatic conditions. Through the high-precision observation of the watershed system, a large amount of high-quality territorial information across multiple fields of earthscienceand multiple time and space scales can be obtained, providing knowledge to construct and analyze the evolutionary mechanisms and trends of physical geographic changes. It can respond to the sustainable development of Taiwan's society and economy. In addition, it can be used as a basis for the planning and implementation of various policies, such as resource regulation, land use, disaster prevention and mitigation.
At present, the observation scope covers the basins and banks of Gaoping River and Zengwen River, carrying out separately the coupling of coastline changes, sediment recharge and hydrodynamic mechanisms (long-term time scale), and mountain-coastal hydrological budget systems analysis (short-time scales). Further, we build core hardware facilities and introduce automatic identification, classification, and data science application to realize the comprehensive integration and digitization of land information.
