Hydrological modelling with components: the OMS3 NewAge-JGrass system
NewAge-JGrass system for forecasting and modelling of water resources in general at the basin scale. As a modern hydrological modelling, it is composed of two parts: (i) the system for data and results visualization based on the Geographic Information System uDig and (ii) the component based …

Large-scale hydrological modelling in the semi-arid north-east of Brazil
… task, dynamic integrated models, containing a hydrological model as one component, are indispensable tools. The main objective of this study is to develop a hydrological model for the quantification of water availability in view of environmental change over a large geographic domain of …

Challenges of regional hydrological modelling in the Elbe River basin : investigations about model fidelity on sub-catchment level
… had to be provided. The semi-distributed eco-hydrological model SWIM was utilised for this task. According to scenario simulations driven by the stochastical climate model STAR, the region would get distinctly drier. However, this thesis focuses on the challenge of meeting the requirement of …

Ensemble-characterisation of satellite rainfall uncertainty and its impacts on the hydrological modelling of a sparsely gauged basin in Western Africa
… with the pre-calibrated parameter values for the hydrological model. A novel approach, the EnsAll method, was developed to calibrate the hydrological model which incorporated each individual ensemble member. The EnsAll calibrated model showed the greatest skill when driven by the ensemble rainfall …

Are all wetland models the same? Comparing wetland models and streamflow regulation of catchment-scale hydrological modelling tools under a changing climate
Comparing how wetlands are simulated in different hydrological modelling tools is needed to identify their suitability in different contexts. A simulated wetland will result in predictions of streamflow regulation, e.g., storing flood water and reducing high flows and releasing water in drier …

Climate Change and Atlantic salmon (Salmo salar): Changes in Flow and Freshwater Habitat in the Burrishoole Catchment
… scale responses in the catchment system. The hydrological projections were examined in the context of the habitat and flow requirements of Atlantic salmon at key stages in their life-cycle (e.g. spawning, migration). Model projections suggest that the catchment is likely to become warmer, with …

Modelling water budget at a basin scale using JGrass-NewAge system
… is one of the most pressing global problems. Hydrological models are useful to understand the water balance of a basin, providing information for water resource forecast, assessment, and management. The effectiveness of the models in estimating the freshwater space-time availability and …

Analyzing and modelling of flow transmission processes in river-systems with a focus on semi-arid conditions
… and semi-arid environments is the scarcity of hydrological data and, consequently, research studies. In this thesis, the hydrology of dryland river systems was analyzed and a semi-distributed hydrological model and a forecasting approach were developed for flow transmission processes in …

Hydrology of a large unstable hillslope at Ebnit, Vorarlberg : identifying dominating processes and structures
… improve the knowledge of control mechanisms of hydrological induced mass movements. To this end, detailed hydrological process studies and physically-based hydrological modelling were applied. The study site is a hillslope in the Dornbirn Ache valley near Bregenz, Austria. This so called Heumös …

Incorporating Wider Infrastructure Disruption in Urban Flooding Resilience Investments
… is developing holistic methodologies integrating hydrological modelling, spatial network analysis, and CI vulnerability assessments to improve flood resilience planning. The study reviews resilience assessment methodologies, highlighting the widespread use of qualitative resilience indicators in …

Changes in hydrological extremes and climate variability in the Severn Uplands
Hydrological extremes within the UK have increased in intensity, frequency and<br/>persistence over recent years and are predicted to increase in variability throughout the 21st<br/>century. Past and future changes in hydrological extremes relative to climate change were<br/>investigated within …

An Analysis of Changes in the Long Term Characteristics of River Flows in the Munster Blackwater Catchment
… before making it fit for purpose for hydrological modelling. This historical data was then used as inputs to the HYSIM and IHACRES lumped conceptual rainfall-runoff models and used to reconstruct flows (hindcast) at the Kilavullen gauge from 1926 to 2009. This hindcast effectively …

End-to-End Ensemble Modelling for Water Resources Planning Under Uncertainty
A hydrological model ensemble, considering two model structures (CatchMOD and PDM), parameter uncertainty and two contrasting methods for estimating potential evapotranspiration (PET), is developed to investigate the relative significance of different sources of uncertainty for water resources …

The viability of transforming stormwater detention ponds into infiltration ponds on the Cape Flats, South Africa
… laboratory investigations, computational hydrological modelling, and financial analysis. A field-scale case study in Mitchells Plain, Cape Town, demonstrated the importance of community engagement in successfully implementing detention pond retrofit projects. The developmental nature of …

The role of hydrological changes in the demise of Iron Age state societies in southern Africa: an integrative study of Mapungubwe, South Africa
… the first, multi- scalar analysis of past hydrological changes in relation to the evolution of complex societies in southern Africa by using an integrated geoarchaeological approach that combines statistical modelling of past rainfall records, geochemical analysis, soil micromorphology, and …

Comparative assessment of flood resilience in urban and rural environments: a case study of Chennai City and Wardha River Sub-basin, India
… the role of land use changes, urbanization, and hydrological factors, it provides insights into the differing mechanisms, impacts, and management strategies required for these environments. In urban areas like Chennai, flooding is predominantly driven by rapid urbanization, unplanned development, …

A multi-criteria decision analysis framework for sustainable rainwater harvesting in Ibadan, Nigeria
… case studies were selected to collect data for hydrological modelling using the RainCycle model. From the results it is found that the most important barrier constraining sustainable RWH regime in Ibadan was obsolete and insufficient operational equipment, followed by poor renumeration of water …

Quantifying the impacts of climate and land use changes on the hydrological response of a monsoonal catchment
… flooding has received great attention in many hydrological modelling studies. However, currently many hydrologists are still uncertain how much these two factors contribute to runoff generation, particularly in monsoon catchments. The river Kelantan is in one of the states in Malaysia, which …
