Introductory Webinar: River Basin Delineation Based on NASA Digital Elevation Data

Date Range: 
November 26, 2019.
Times: 
10:00-11:00 & 16:00-17:00 EST (UTC-5)
Registration Closes:

River basins (known as watersheds in North America) are areas of land that drain precipitation, surface water, and underlying groundwater into a river and its tributaries, eventually reaching a common outlet such as a lake, reservoir, river, or estuary. The drainage pattern is from smaller sub-basin to larger sub-basin, and from higher elevation to lower elevation. Land surface processes, precipitation, storm water, and wastewater runoff within basins have substantial impact on quantity and quality of the water draining into tributaries. Surface topography and elevation generally determine boundaries or drainage divides between sub-basins. Delineation is crucial for assessing the contribution to water quantity and quality in the river system, and for planning better land and water management practices.

This lightning-style webinar will focus on describing NASA digital elevation data and its application in deriving river basin information by using Hydrological data and maps based on SHuttle Elevation Derivatives at multiple Scales (HydroSHEDS) database. Exercises with instructions for river basin delineation using HydroSHEDS will be provided.

Learning Objectives: 

By the end of this training, attendees will be able to:

  • Delineate a river sub-basin
  • Determine flow direction in the area of their interest using HydroSHEDS
Course Format: 
  • The webinar will be conducted in English, with Spanish translation of the material available
  • A single one-hour presentation, demonstration, and question and answer session
  • There will be identical sessions at two different times of the day
  • No certificate of completion will be offered for this webinar
Prerequisites: 

Participants that do not have an understanding of the fundamentals of remote sensing may not be prepared for the pace and level of the live training.

Audience: 

Local, regional, state, federal, and international entities, including public and private sector organizations, engaged in water resources, floods, and river basin management, and water quality management.
