Collection and analysis of watershed hydrological data (Preciptiation, Runoff, sediment and nutrient yields)

Abstract

Specific objective of this activity was to monitor the meteorological variable, surface hydrology and sediment and nutrients (available P, Total N and Organic carbon) yields at the Gumara-Maksegnit watershed and to use these data for the calibration and validation of hydrological and bio-economic models and as reference information for similar watersheds. The selected watershed Gumara Maksegnit watershed has an area of 5,600ha and includes several sub-watersheds among which Abakaloye and Ayaye with respective surface area of about 32ha and 24ha, which were selected for sub-watershed scale monitoring. Monitoring and assessment have been conducted since 2011, generating a 6 years long data series that is being used for calibration and validation of hydrological models. This report summarizes the data collected during the project duration (2013 to 2015) at both watershed and sub-watershed scale. Long term partners of this specific activity are ICARDA, ARARI, and Boku. It has to be noted that the data presented here are currently being elaborated for publication and fr reasons of space are incomplete. This report is only aimed at illustrating the nature and quality of the dataset, and to broadly visualize the information collected.
