  • Application of a catchment water quality model for an East–Australian catchment

    This paper presents the calibration of a catchment water quality model developed for the continuous simulation of stormwater pollutants from a catchment to the catchment outlet. Calibration of the model was performed using the rainfall and water quality data collected for 'Saltwater Creek Catchment' in Gold Coast, Australia. Runoff estimations from the hydrologic model were compared with ...

  • History and perspectives of hydrological catchment modelling

    This paper presents a brief historical excursus on the development of hydrological catchment models together with a number of possible future perspectives. Given the wide variety of available hydrological models which, according to the embedded level of prior physical information, vary from the simple input–output lumped models to complex physically meaningful ones, the paper suggests how ...

  • Application of a distributed catchment model to investigate hydrological impacts of climate change within Poyang Lake catchment (China)

    The extreme cycles of flood and drought in the Poyang Lake catchment (China) place immense pressure on the region's water users and ecosystems. This study examines potential impacts of future climate change in the Poyang Lake catchment using the popular regional climate model, COSMO-CLM, and a distributed hydrological model, WATLAC. Near-future projections (2016–2035) indicate that the mean ...

  • Application of deterministic distributed hydrological model for large catchment: a case study at Vu Gia Thu Bon catchment, Vietnam

    In order to create a tool to help hydrologists and authorities to have good understanding about occurrences in stream flow regime together with its variation in the future under the impact of climate change in the Vu Gia Thu Bon catchment, a deterministic distributed hydrological model has been developed and constructed. This model covers the major processes in the hydrologic cycle including ...

  • Validation of a mesoscale hydrological model in a small-scale forested catchment

    The aim of this study was to examine the abilities of the mesoscale ecohydrological model Soil And Water Integrated Model (SWIM) to simulate discharge, soil moisture, and groundwater dynamics in a small-scale forested catchment. Moreover, the influence of two lateral flow computation techniques on the simulation efficiency was assessed. Generally, the discharges were simulated poorly. ...

  • Integrated conceptual modelling of faecal contamination in an urban estuary catchment

    Urban stormwater is regarded as a key input of faecal contamination in receiving water bodies and therefore, a major concern for health risks associated with aquatic recreation. Wastewater leakages, cross connections and overflows, together with faeces washed from surfaces during rainfall events, are possible origins of faecal contamination which enter these water bodies through stormwater ...

  • Improving WetSpa model to predict streamflows for gaged and ungaged catchments

    In the second phase of the Distributed Model Intercomparison Project (DMIP2), the WetSpa model is applied to simulate flows at basin and subbasin scales. Parent basins and their nested subbasins are modeled as gaged and ungaged basins, respectively. Available observations in the subbasins were only used to validate the model predictions. Gaged basins simulation results show that the predictions ...

  • Statistical characteristics of rainfall in the Onkaparinga catchment in South Australia

    The main objective of this study was to investigate the statistical characteristics of point rainfall and the novelty of the work was the development of a hybrid probability distribution that can model the full spectrum of daily rainfall in the Onkaparinga catchment in South Australia. Daily rainfall data from 1960 to 2010 at 13 rainfall stations were considered. Spatial dependency among the ...

  • Distributed conceptual modelling in a Swedish lowland catchment: a multi-criteria model assessment

    Operational management and prediction of water quantity and quality often requires a spatially meaningful simulation of environmental flows and storages at the catchment scale. In this study, the performance of a fully distributed conceptual hydrologic model was evaluated based on the HBV (Hydrologiska Byråns Vattenbalansavdelning) and TACD (Tracer Aided Catchment model – ...

  • EEA Catchments and Rivers Network System – ECRINS v1.1

    EEA Catchments and Rivers Network System – ECRINS v1.1 The European Catchments and Rivers Network System (ECRINS) is the hydrographical system currently in use at the European Environment Agency (EEA) as well as widely serving as the reference system for the Water Information System for Europe (WISE). The first version of ECRINS (version 0 or â) was released in December 2008, and was ...

  • Spatially distributed lateral nitrate transport at the catchment scale

    Received for publication January 23, 2009. In river catchments, N transformation and storage processes during lateral transport are important in controlling N loads of surface waters. There is a lack of approaches which capture lateral flows and associated N transformation in a spatially distributed way. The aim of this paper is to develop a new conceptual N transport and transformation model ...

  • Hydrological response of the Ötztal glacierized catchments to climate change

    This paper investigates the hydrological response of glacierized headwater catchments to future climate change in the Ötztal Alps, Austria. To this end, two conceptual hydrological models, HBV (Hydrologiska Byråns Vattenbalansavdelning) and HQsim, are applied for the simulation of future daily discharge in three (nested) catchments with varying degrees of glaciation. The models are forced ...

  • GIS-based SWMM model for simulating the catchment response to flood events

    The Storm Water Management Model (SWMM) has been an effective tool for simulating floods in urban areas, but has been seldom applied for river systems. In this study, a geographic information system (GIS)-based SWMM model was developed to authenticate the model's viability as a streamflow simulator for modeling floods in the Brahmani river delta. The model was set up using a Shuttle Radar ...

  • An alternative approach to modelling stormwater runoff from small urban catchments

    The inability of current stormwater quality models to reproduce historical pollutographs accurately and reliably has prompted the need to introduce alternative approaches to simulate stormwater runoff from urban catchments. In view of the increasing popularity of designing urban stormwater systems using the Water Sensitive Urban Design (WSUD) approach, it is also essential to adopt a modelling ...

  • Tracing fine sediment sources in small mountain catchment

    Fine sediment represents an important diffuse source pollutant in surface waters, due to its role in governing the transfer and fate of many substances, including nutrients, heavy metals, pesticides and other organic contaminants, and its influence on aquatic ecology. Therefore, catchment management strategies frequently need to include provision for the control of sediment mobilization and ...

  • Modelling catchment inflows into Lake Victoria: regionalisation of the parameters of a conceptual water balance model

    The goal of this study was to evaluate regionalisation methods that could be used for modelling catchment inflows into Lake Victoria. WASMOD, a conceptual water balance model, was applied to nine gauged sub-basins in Lake Victoria basin in order to test the transferability of model parameters between the basins using three regionalisation approaches. Model calibration was carried out within the ...

  • Combining modeling and monitoring to study fecal contamination in a small rural catchment

    The present study sought to identify Escherichia coli sources in a small catchment and to use the agro-hydrological model soil and water assessment tool (SWAT) to estimate their impact on river water quality. The innovative aspects of this research are to assess the hourly variations of fecal contamination and to take these variations into account in the model to provide a better evaluation of ...

  • Uncertainty in hydrological modelling of climate change impacts in four Norwegian catchments

    Projections for the hydrological impacts of climate change are necessarily reliant on a chain of models for which numerous alternative models and approaches are available. Many of these alternatives produce dissimilar results which can undermine their use in practical applications due to these differences. A methodology for developing climate change impact projections and for representing the ...
