  • The influence of the land surface on hydrometeorology and ecology: new advances from modeling and satellite remote sensing

    The importance of land surface processes has long been recognized in hydrometeorology and ecology for they play a key role in climate and weather modeling. However, their quantification has been challenging due to the complex nature of the land surface amongst other reasons. One of the difficult parts in the quantification is the effect of vegetation that are related to land surface processes ...

  • Hydrologic data as a human right? Equitable access to information as a resource for disaster risk reduction in transboundary river basins

    Principles of equitable and reasonable use underpin international water agreements. Despite the potential for hydrologic information to enhance resilience to extreme events, comparable application of just principles to the distribution of hydrometeorological data is poorly established. Within the Ganges–Brahmaputra–Meghna (GBM) river basin, we find that water allocation agreements ...

  • Climate change and water resources in Turkey: a review

    There is a close link between climate change and water resources owing to the strong relationship between climate and hydrology. Effects of climate change on water availability have potential to impact water supply for domestic, agricultural, industrial, environmental, and hydro-electricity generation purposes in Turkey. Thereby, it is necessary to develop hydro-meteorological impact studies in ...

  • Climate Change Impact on Hydro-meterological Variables: A Review

    Due to increasing concentration of carbon dioxide and other greenhouse gases in the atmosphere, several hydro-meteorological variables are likely to be significantly impacted. Reservoir operations, crop production, erosion processes, runoff production and many other hydrological processes are likely to be impacted by the ongoing climate change. This paper presents a comprehensive review of ...

  • Development of HydroClimatic Conceptual Streamflow (HCCS) model for tropical river basin

    Combined processes of land-surface hydrology and hydroclimatology influence the response of a watershed to different hydroclimatic variables. In this paper, streamflow response of a watershed to hydrometeorological variables is investigated over a part of two tropical Indian rivers – Narmada and Mahanadi. The proposed HydroClimatic Conceptual Streamflow (HCCS) model is able to consider ...

  • Neural network approach to output updating for the physically–based model of the Upper Thames River watershed

    This study presents an output updating procedure for the deterministic physically–based model of the Upper Thames River watershed, Ontario, Canada. In addition to streamflow and rainfall, this procedure uses as inputs meteorological variables not employed in the model calibration. The main hydrological processes involved in transformation of rainfall into runoff are mathematically expressed using ...

  • The associated risks on water resources in Western Macedonia under climate change

    This paper assesses the impacts of climate change on water resources in the Western Macedonia water district, located in northern Greece. Some critical water management issues, such as reservoir storage and water supply for agriculture and domestic use, are investigated. A conceptual water balance model was calibrated using monthly historical hydrometeorological data. The proposed model was ...

  • Advanced procedures for risk assessment and management in Russia

    The Russian Federation has developed a comprehensive, high-technology strategy for coping with natural and technological emergencies, risk reduction, and disaster management. The strategy is implemented under special Russian Federal Programs. One of the main goals of these Programs is the creation of the State Unified System of Monitoring and Forecast of Emergency Situations. The Agency of ...

  • The influence of climate and dam construction on the Ibera wetlands, Argentina

    Abstract  The purpose of this work is to assess the impact on the Esteros del Ibera wetland ecosystem caused by the Yacyreta dam, a large hydroelectric power plant on the Parana River, Argentina, in comparison to other factors of environmental change. The project of the dam started around 1970. The power plant began operating in 1994. In 1989, the neighboring Ibera wetland ecosystem showed ...


  • Temporal variations of runoff in a rapidly urbanizing semi-arid Chinese watershed

    Rapid urbanization on streamflows may directly affect or be restricted by the sustainability of local water resources. This is particularly true for arid/semiarid areas such as the Wulanmulun River watershed in the rapidly-developing Ordos region of north central China. From 1997 to 2012, the gross domestic product (GDP) of the region increased fifty-fold, while the urban area grew by a factor ...

  • The Thames flood series: a lack of trend in flood magnitude and a decline in maximum levels

    The flow series for the River Thames near its tidal limit is one of the most studied in the world. Its length and completeness, and the richness of the historical information which augments the formal flow record, ensures that the series is of immense value. However, the variability in flood magnitude and frequency that it captures needs to be interpreted with caution. The homogeneity of the time ...

  • Changes in river discharge structure and regime in mining-industrial-urban areas

    In mining-industrial-urban areas, the variability of river discharge is regulated, directly or indirectly, by human economic activity. This results from the presence of alien water, which often comes from outside the catchment area, is discharged into the river network. This water includes industrial and municipal wastewater and deep-drainage mine water. Simultaneously, as a result of water ...

  • Long-term changes in the northern Adriatic ecosystem related to anthropogenic eutrophication

    Knowledge of the mechanisms driving long-term changes in the nutrient and primary production cycles represents a basic step to verify real eutrophication trends in shallow marine ecosystems, such as the northern Adriatic open waters. In fact, this ecosystem appears to be especially sensitive to seasonal and long-term variations of the anthropogenic nutrient load (primarily the Po River ...

  • Global water estimates `uncertain`

    Great uncertainty exists regarding estimates of the global water budget (the amount of water involved in the hydrological cycle every year) because of discrepancies between global atmosphere and ocean models, and direct observations, a study has found. Furthermore, these uncertainties may worsen as the number of ...

  • The spectral absorption coefficient at 254 nm as a real-time early warning proxy for detecting faecal pollution events at alpine karst water resources

    Because spring water quality from alpine karst aquifers can change very rapidly during event situations, water abstraction management has to be performed in near real-time. Four summer events (2005–2008) at alpine karst springs were investigated in detail in order to evaluate the spectral absorption coefficient at 254 nm (SAC254) as a real-time early warning proxy for faecal pollution. For the ...
