Assessments of water and energy security over historical future periods require hydrologic models that can accurately simulate reservoir operations. However, scare operation data limits the accuracy current representations in simulating behaviors. Furthermore, reliability these under changing inflow regimes remains unclear, which makes their application for long planning horizons questionable. ...

the volume and surface area of the coast is a function of basin water levels. recognizing the factors of coastal geomorphologic changes could have a pivotal role in planning and managing the coast. effective factors in the formation and evolution of geomorphologic factors such as geological, tectonic, paleoclimatic, paleoclimatic and sea level changes have been considered in this study and the ...

This paper presents the feasibility of estimating discharges from Roseires Reservoir (Sudan) for the period from 2002 to 2010 and Aswan High Dam/Lake Nasser (Egypt) for the periods 1999–2002 and 2005–2009 using satellite altimetry and imagery with limited in situ data. Discharges were computed using the water balance of the reservoirs. Rainfall and evaporation data were obtained from public dom...

The special issue (SI) “Radar Systems for the Societal Challenges” is an updated survey of recent advances in radar systems, encompassing several application fields and related to the impact on society. In fact, radar technology is now pervasive in society and is crucial for tackling social and economic issues for the wellbeing of the population. In fact, in addition to the classical applicatio...

Mapping the mesoscale surface velocity stream function by combining estimates of surface height from satellite altimetry and surface currents from sequential infrared (sea-surface temperature) imagery using optimal interpolation is described. Surface currents are computed from infrared images by the method of maximum crosscorrelations (MCC) and are combined with altimeter sealevel anomaly data ...

1. ABSTRACT Experiments undertaken in the 1970s demonstrated the sensitivity of radar backscatter to soil moisture conditions [1]. More recent advances in active microwave remote sensing have confirmed the potential for using current satellite data for the generation of soil moisture maps at different scales [2,3]. However, in addition to its strong sensitivity to the soil water content, radar ...

Satellite radar altimetry has been widely utilized in hydrological research, particularly with the advent of Sentinel-3, a Synthetic Aperture Radar (SAR) altimeter operating globally and equipped an innovative onboard tracking system referred to as open-loop command (OLTC). Utilizing pseudo-DEM (Digital Elevation Model), controlled through OLTC, holds significant promise for reliable observatio...
