Paper Title: Satellite-based evapotranspiration over Gezira Irrigation Scheme,Sudan: A comparative study
Prepared by: Mohamed El Sayed Embaby
Description:

tUnderstanding the spatio-temporal variation of actual evapotranspiration (ETa) over irrigated agricul-tural areas helps to manage water. Many remote sensing (RS) methods have been developed recentlyto estimate ETa. Nevertheless, selecting the suitable method is still a challenge. The objective of thisresearch is to evaluate four RS methods for estimating ETaover the large-scale Gezira Scheme of Sudan.Three methods, namely Surface Energy Balance Algorithm for Land (SEBAL), Mapping EvapoTranspira-tion at High Resolution with Internalized Calibration (METRIC) and Simplified Surface Energy Balance(SSEB), were applied using Landsat images. Another RS dataset, i.e. ETaproduct from Moderate Resolu-tion Imaging Spectroradiometer (MODIS) satellite (MOD16A2), was also used in the comparison. The ETamethods were validated using field-scale water balance (WB) estimates during the 2004 crop season.Furthermore, the present study suggested the use of Normalized Difference Vegetation Index (NDVI)...

Paper Title: Hydrological, socio-economic and reservoir alterations of Er Roseires Dam in Sudan
Prepared by: Mohamed El Sayed Embaby
Description:

Er Roseires Dam plays a key role in controlling the Blue Nile flow in Sudan. This study explores the influence of the dam on the hydrological regimes,which in turn have implications for the ecosystem. The Range of Variability Approach (RVA) - based on a set of 32 indicators - was applied over the period 1965 to 2014 to establish a safe range of river flow. Moreover, remotely-sensed data of the Normalized Difference Vegetation Index (NDVI) was used to analyse...
