Abstract
Computational capabilities of online cloud-based platforms offered a dramatic increase of the possibilities in the field of geosciences. The novel Google Earth Engine (GEE) platform is among the most powerful and innovative tools, making available both a cloud computational system and wide collections of available satellite remote sensing datasets. This paper presents the GEE analysis of the impacts of Landscape Restoration and Water Harvesting (LRWH) on water conservation potential of a pilot catchment in Tigray Region, Ethiopia. A synthetic Water Conservation Index (WCI) was defined as a function of monthly average Normalized Different Infrared Index (NDII), obtained by Landsat 7 Tier 1 8-Day Composites, and the rainfall amount of June, July and August, calculated from pentadal Climate Hazards Group InfraRed Precipitation with Station data(CHIRPS) dataset. Results showed a substantial increase of the WCI after the rainy season for September, with a statistical significance of p
