Hydrological Impacts Of Climate Change – Challenges, Uncertainty And Limitations, Shreedhar Maskey, Yurong Hu, Anshul Agarwal, Dinesh Bhatt
International Conference on Hydroinformatics
How climate change impacts water resources in the future is an important question that all hydrologists want to have an answer. Climate prediction scenarios are available from many Global Circulation Models for the 21st century. These prediction datasets are typically used as input to a hydrological model for simulating impacts on hydrology, particularly river runoff, evaporation, and storage changes. Because hydrological models are usually run on a much smaller resolutions than climate models, the climate prediction datasets are usually downscaled to represent local climate for using in a hydrological model. The uncertainty in the GCMs, downscaling and hydrological models makes …

Interactive Web-Based Flood Simulation System As An Education Platform For Hydrological Concepts, Ibrahim Demir
International Conference on Hydroinformatics
Recent developments in web technologies make it easy to manage and visualize large data sets with general public. Novel visualization techniques and dynamic user interfaces allow users to create realistic environments, and interact with data to gain insight from simulations and environmental observations. The floodplain simulation system is a web-based 3D interactive flood simulation environment to create real world flooding scenarios. The simulation systems provides a visually striking platform with realistic terrain information, and water simulation. Students can create and modify predefined scenarios, control environmental parameters, and evaluate flood mitigation techniques. The web-based simulation system provides an environment for students …

Towards A Decision Support System For Flood Management In A River Basin, Luis Vieira, Jose Pinho, Dirk Schwanenberg
International Conference on Hydroinformatics
The world is experiencing a countless number of impressive and devastating floods causing a range of health impacts and risks with hundreds of thousands of people losing their lives or becoming homeless in a matter of hours. EU Floods Directive requires the developing of flood hazard maps, which may include information on hydrological and hydrodynamics characteristics of vulnerable regions, i.e. inundated areas and river flow discharges. Prediction of flood events can accurately be achieved by applying mathematical modelling for describing rainfall-runoff phenomena as well as surface waters hydrodynamics. Moreover, reservoirs can be properly operated in order to minimize flood events …

International Conference on Hydroinformatics
One of the main challenges in hydro-meteorological research (HMR) is predicting the impact of weather and climate changes on the environment, society and economy, including local severe hazards such as floods and landslides. At the heart of this challenge lies the ability to have easy access to hydro-meteorological data and models, and facilitate the collaboration across discipline boundaries. Within the DRIHM project (Distributed Research Infrastructure for Hydro-Meteorology, www.drihm.eu, EC funded FP7 project 2011-2015) we develop a prototype e-Science environment to facilitate this collaboration and provide end-to-end HMR services (models, datasets, and post-processing tools) at the European level, with the ability …

Induction Of Governing Differential Equations From Hydrologic Time Series Data Using Genetic Programming, Jayashree Chadalawada, Vladan Babovic
International Conference on Hydroinformatics
Induction of Governing Differential Equations from Hydrologic Time Series Data using Genetic Programming Jayashree Chadalawada and Vladan Babovic This contribution describes an evolutionary method for identifying causal model from the observed time-series data. In the present case, we use a system of ordinary differential equations (ODEs) as the causal model. Usefulness of the approach is demonstrated on real-world time series of hydrologic processes and the unknown function of governing factors are determined. To explore the evolutionary search space more effectively, the right hand sides of ODEs are inferred by genetic programming (GP). The importance of different fitness criteria, as well …
