Description

Repository built in Google Earth Engine (GEE) and Javascript.

Each section is described below:

• First section, calculate NVDI, MNDWI and AWEI index

  https://github.com/CarlosMendez1997Col/Monitoring-water-resources-using-Google-Earth-Engine-and-Javascript/tree/main/01.%20Nvdi%2C%20Mndwi%20and%20Awei

• Second section, analyze surface water bodies (watersheds, rivers and lakes)

  https://github.com/CarlosMendez1997Col/Monitoring-water-resources-using-Google-Earth-Engine-and-Javascript/tree/main/02.%20Surface%20Water

• Third section, analyze precipitation and rainfall in time series (monthly and yearly)

  https://github.com/CarlosMendez1997Col/Monitoring-water-resources-using-Google-Earth-Engine-and-Javascript/tree/main/03.%20Precipitation%20and%20rainfall

• Fourth section, shows spatial and temporal variations in river levels

  https://github.com/CarlosMendez1997Col/Monitoring-water-resources-using-Google-Earth-Engine-and-Javascript/tree/main/04.%20Hidrology

• Fifth section, calculate water balance and analyze droughts

  https://github.com/CarlosMendez1997Col/Monitoring-water-resources-using-Google-Earth-Engine-and-Javascript/tree/main/05.%20Water%20balance%20and%20drought

• Sixth section, analyze reservoir levels and groundwater
