River–Dam Schematic
Provides schematized information to easily identify the locations of dams, rivers, and water supply facilities in the watershed, as well as water flow information
Enables an at-a-glance understanding of river and water supply facility status within the watershed, and allows real-time monitoring of water level and flow at each point -
Real‑Time Hydrologic Data
Provides an integrated monitoring function for hydrological conditions (e.g., rainfall, water level, inflow, discharge, storage, etc.) by water resource facility purpose and watershed
Provides functions to check dam discharge status and to view detailed real-time hydrological data -
Real‑Time River Stage
Provides a function to simultaneously display and monitor real-time river water levels from up to 12 gauging stations on the platform
Enables monitoring of flood arrival time at major points and verification of risk levels by station through comparison of water level changes between upstream and downstream rivers -
Hydrologic Data Query
Provides a function to monitor river water level conditions in the form of a longitudinal river profile on the platform
Provides monitoring functions for water level status by dam and river gauging station, as well as risk conditions based on flood watch and warning criteria
-
River flood simulation
A model that predicts inundation areas caused by river overflow resulting from rising river water levels
-
Urban flood simulation
Predicts inundation areas by considering both river overflow (external flooding) and urban drainage (internal flooding)
-
Flood Risk Early Warning
Provides alarm and alert functions, including warning broadcasts, in the event of anticipated risk situations such as dam floodgate discharge
-
Flood analysis results dashboard
Provides flood analysis results in a summarized dashboard format to support rapid decision-making and efficient flood response
