  1. In a river-flood workflow, how do hydrologic and inundation models differ?
    • Hydrology estimates water flow, while inundation modeling estimates where water may spread
    • Both directly predict earthquake waves
    • Hydrology edits satellite photos and inundation translates text
    • They measure only air temperature
  2. What role can NOAA’s National Water Model play alongside official forecasts?
    • Replace every local warning and evacuation decision
    • Provide simulated observed and forecast streamflow to complement NWS products
    • Guarantee the exact depth at every street address
    • Measure future rainfall without a model
  3. Why can a recurrent model such as an LSTM be used in river-flow forecasting?
    • It guarantees correct river levels without observations
    • It measures discharge directly with no sensors
    • It can represent sequential inputs and dependencies over time
    • It removes uncertainty from weather forecasts
  4. What lead time does Google’s November 2024 flood-model announcement describe?
    • Hingga 2 jam
    • Hingga 6 bulan
    • Hanya setelah banjir mulai terjadi
    • Sampai sekitar 7 hari
  5. How did Google distinguish two coverage groups in its November 2024 flood-model announcement?
    • 100 countries with verified data and up to 150 with data based on virtual gauges
    • Every street worldwide with verified depths
    • Only one country with no forecasts elsewhere
    • Every coastal storm surge with guaranteed evacuation time
  6. Manfaat praktis dari prakiraan banjir yang akurat adalah:
    • Menghentikan hujan agar tidak turun
    • Menentukan waktu evakuasi dan menentukan posisi sumber daya penyelamatan
    • Menghilangkan kebutuhan akan bendungan
    • Memprediksi gempa bumi
  7. Why are ungauged basins difficult for traditional river forecasting?
    • They receive no rainfall
    • They cannot be mapped
    • They lack local streamflow observations for calibration and validation
    • They never experience floods
  8. What is one limitation of riverine flood forecasts for flash flooding?
    • They give exact street-level outcomes everywhere
    • They reliably predict every flash flood
    • They replace local emergency services
    • They may not resolve rapid local runoff and urban drainage hazards at the same scale
