Soil moisture is widely recognized as a key parameter in the mass and energy balance between land surface atmosphere and, hence, potential societal benefits of an accurate estimation soil are immense. Recently, scientific community making great effort for addressing over large areas through situ sensors, remote sensing modelling approaches. The different techniques used monitoring hydrological applications briefly reviewed here. Moreover, some examples which satellite data successfully...
To promote the advancement of novel observation techniques that may lead to new sources information help better understand hydrological cycle, International Association Hydrological Sciences (IAHS) established Measurements and Observations in XXI century (MOXXI) Working Group July 2013. The group comprises a growing community tech-enthusiastic hydrologists design develop their own sensing systems, adopt multi-disciplinary perspective tackling complex observations, often use low-cost...
Abstract. Effective agricultural water management requires accurate and timely information on the availability use of irrigation water. However, most existing (IWU) lacks objectivity spatiotemporal representativeness needed for operational meaningful characterization land–climate interactions. Although optical remote sensing has been used to map area affected by irrigation, it does not physically allow estimation actual amount applied. On other hand, microwave observations moisture content...
Abstract The Surface Water and Ocean Topography (SWOT) mission will vastly expand measurements of global rivers, providing critical new data sets for both gaged ungaged basins. SWOT discharge products (available approximately 1 year after launch) provide all river that reaches wider than 100 m. In this paper, we describe how produced archived by the US French space agencies be computed from water surface elevation, width, slope ancillary data, along with expected accuracy. We present first...
Abstract. Irrigation water use represents the primary source of freshwater consumption by humans. The amount withdrawals for agricultural purposes is expected to further increase in upcoming years face rising world population and higher living standards. Hence, effective plans enacting a rational management are urgent, but they limited knowledge gaps about irrigation. Detailed information on irrigation dynamics (i.e., extents, timing, amounts) generally lacking worldwide, satellite...
Climate change is profoundly affecting the global water cycle, increasing likelihood and severity of extreme water-related events. Better decision-support systems are vital to accurately predict monitor environmental disasters optimally manage resources. These must integrate advances in remote sensing, situ , citizen observations with high-resolution Earth system modeling, artificial intelligence (AI), information communication technologies, high-performance computing. Digital Twin (DTE)...
A methodology to estimate the discharge along rivers, even poorly gauged ones, taking advantage of water level measurements derived from satellite altimetry is proposed. The procedure based on application Rating Curve Model (RCM), a simple method allowing for estimation flow conditions in river section using only levels recorded at that site and discharges observed another upstream section. European Remote-Sensing Satellite 2, ERS-2, Environmental Satellite, ENVISAT, data are used provide...
Abstract Limitations of satellite radar altimetry for operational hydrology include its spatial and temporal sampling as well measurement problems caused by local topography heterogeneity the reflecting surface. In this study, we develop an approach that eliminates most these limitations to produce approximately 3 day resolution water level time series from original typically (sub)monthly data sets Po River in detail, Congo, Mississippi, Danube Rivers. We follow a geodetic which, after...
Data assimilation (DA) of satellite soil moisture (SM) observations represents a great opportunity for improving the ability rainfall-runoff models in predicting river discharges. Many studies have been carried out so far demonstrating possibility to reduce model prediction uncertainty by incorporating SM observations. However, large discrepancies can be perceived between these with result that successful DA is not only related quality but significantly controlled many methodological and...
Abstract. Satellite-based Earth observations (EO) are an accurate and reliable data source for atmospheric environmental science. Their increasing spatial temporal resolutions, as well the seamless availability over ungauged regions, make them appealing hydrological modeling. This work shows recent advances in use of high-resolution satellite-based EO In a set six experiments, distributed model Continuum is up Po River basin (Italy) forced, turn, by satellite precipitation evaporation, while...
Abstract. Inundation is one of the major natural hazards in Europe. The evaluation flood hazard and risk not straightforward mainly due to monitoring system that poor or uniformly distributed territory. ESA Earth Observation Program, including a series satellites, Sentinels, for operative observation phenomenon, e.g. inundations, can potentially reduce gap. Sentinel-1 (SAR: synthetic aperture radar) Sentinel-2 (optical) have been demonstrated be suitable mapping flooded areas, but despite...
Abstract The ability to map floods from satellites has been known for over 40 years. Early images of were rather difficult obtain, and flood mapping was thus opportunistic limited only a few case studies. However, the last decade, with proliferation open-access EO data, there much progress in development Earth Observation products services tailored various end-user needs, as well its integration modeling prediction efforts. This article provides an overview use satellite remote sensing...
