Snow Water Volume & Water Resources - Kajaki Dam catchment, Afghanistan
Snow water volume (SWV) can be used to predict upcoming floods & droughts during the irrigation season in Central Asia. In this video I will show you how to use the Snow Water Equivalent (SWE) maps and SWV data from the USGS FEWS-Net website to better understand the 2021 drought in Afghanistan. We will use the Kajaki Dam catchment in Helmand Province to compare the available water resources stored as snow at the end of winter from 2001 - 2021. In mid-March 2021 only 30% of the average snow water volume was available for the irrigation season. This has led to failed crops, malnutrition and starvation, which poses critical challenges to the people of Afghanistan - in particular the staff of the Ministry of Energy and Water (MEW) who are responsible for water allocation.
In this video we use Excel to store the Snow Water Volume data in database format. We then process and present it in charts using PivotTables and PivotCharts. The Kajaki dam catchment Excel spreadsheet can be downloaded from Google Drive: https://bit.ly/3mw0JJq
My special thanks to Asadullah Haydarziy for sharing with me some recent pictures of the terrible drought situation in Helmand Province.
