Training Information


  • Type: Synchronous online
  • Training Dates: 2-5 Nov 2021
  • Audience Location: Colombia
  • Partner: IDEAM, Colombia

    • Intermediate familiarity with remote sensing
    • Basic familiarity with computer programming language (i.e. Python, JavaScript, etc.)

Training Description


Many nations in South America are subject to frequent impacts from geophysical and weather-related hazards. With Colombia being frequently obstructed by clouds, this training is introducing concepts and workflows for efficient and weather-independent flood monitoring. The training covers three main components: (1) streamflow forecasting techniques; (2) SAR-based surface water mapping workflows; and (3) approaches to combine runoff forecasting, SAR, and machine learning to enable water extent forecasting with high (daily) temporal resolution.

For this training, we teamed up with partners at the BYU Hydroinformatics Lab, IDEAM, and SERVIR Amazonia, who added their expertise on river runoff forecasting and machine learning to the training. The workshop included lectures and hands-on data processing labs using Jupyter notebooks.
