  • The Basics of Evapotranspiration

    Evapotranspiration (ET) represents the loss of water from the Earth’s surface from the combination of direct evaporation and plant transpiration. ET is usually expressed as a rate such as inches per day. Knowledge of ET is important for irrigation scheduling but it is also an important factor for other land use applications such as septic tank drain fields, watershed level budgeting, and ...

  • Integrating water resources management in eco-hydrological modelling

    In this paper the integration of water resources management with regard to reservoir management in an eco-hydrological model is described. The model was designed to simulate different reservoir management options, such as optimized hydropower production, irrigation intake from the reservoir or optimized provisioning downstream. The integrated model can be used to investigate the impacts of ...

  • Assessment of groundwater resources using climatic and hydrologic budget methods

    The Pageru River basin is situated in drought prone areas of the Rayalaseema region, Andhra Pradesh, South–India. In the absence of perennial surface water bodies, groundwater is an important source of water and has played an important role in developing industry, agricultural and domestic supply. In the present study, the efforts have been made to assess the groundwater resources using both ...

  • Evaluation of the impacts of future hydrological changes on the sustainable water resources management of the Richmond River catchment

    The conceptual rainfall–runoff (HBV model) is applied to evaluate impacts of future climate changes on the hydrological system of the Richmond River catchment, Australia. Daily observed rainfall, temperature and discharge and long-term monthly mean potential evapotranspiration from the hydro-meteorological stations within the catchment over the period 1972–2014 were used to run, calibrate and ...

  • 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 ...

  • The role of conceptual hydrologic model calibration in climate change impact on water resources assessment

    Assessment of climate change (CC) impact on hydrologic regime requires a calibrated rainfall-runoff model, defined by its structure and parameters. The parameter values depend, inter alia, on the calibration period. This paper investigates influence of the calibration period on parameter values, model efficiency and streamflow projections under CC. To this end, a conceptual HBV-light model of ...

  • Custom functionality and integrative approaches for hydrological modelling tools for water resources planning and management

    This paper outlines the application and usefulness of a software platform that enables hydrologists to develop custom functionality in a new hydrological modelling tool, eWater Source, designed for water resources planning and management. The flexible architecture of the software allows incorporation of third-party components as plug-ins to add new capabilities that are not built in. Plug-ins ...

  • Integrated actions in the management of critical hydrologic events

    Owing to the increase in urban populations, there has also been an increased incidence of critical events, especially those related to floods and landslides. Since the implementation of the National Civil Defense System in Brazil, a focus on disaster management is no longer the answer when assisting those affected; instead, the answer has become managing disaster risk, in addition to the ...

  • Data mining process for modeling hydrological time series

    The main purpose of this study was to develop an optimum flow prediction model, based on data mining process. The data mining process was applied to predict river flow of Seyhan Stream in the southern part of Turkey. Hydrological time series modeling was applied using monthly historical flow records to predict Seyhan Stream flows. Seyhan Stream flows were modeled by Markov models and it was seen ...

  • Impacts of urbanization on hydrology in the Yangtze River Delta, China

    The Yangtze River Delta is one of the most developed regions in China and the rapid development of urbanization have greatly influenced regional hydrology and water resources. Taking several typical urbanizing areas in the Yangtze River Delta as examples, this paper probes into the impacts of urbanization on hydrologic cycle and hydrological process with the support of RS, GIS and hydrological ...

  • Modelling the hydrologic effects of land-use and climate changes

    Climate and land use affect water quantity and quality; however, the complex relations of climate and land use regarding flow and instream nutrient levels have yet to be elucidated. This study aims to assess the hydrologic effects of different land-use and climatic regimes in the Lower Great Miami River Basin. The modelling results from BASINS showed that, as expected, agricultural lands and the ...

  • Water resources management

    Managing regional or national water resources demands the integration of patterns and processes of both natural and social systems. This is essential to achieve the optimum interaction of man and nature since every aspect of water use and disposal impinges on ecosystems to a greater or lesser extent. Sustainability is the key issue: how can sustainable yields by abstraction from rivers, ...

  • PondR: a process-oriented model to simulate the hydrology of drainage ponds

    Drainage ponds are a useful measure to manage water resources. However, these small water bodies are characterized by highly dynamic internal processes. This article discusses a simple process-oriented model developed to simulate temporal dynamics of internal processes within drainage ponds. The PondR model is able to simulate the relevant hydrological processes of the pond by using commonly ...
