Community-based early warning systems for flood risk mitigation in Nepal

Virtual Dike and Flood Simulator: Parallel distributed computing for flood early warning systems

The paper presents two simulation modules –Virtual Dike and Flood Simulator– developed for flood Early Warning Systems (EWS). The UrbanFlood EWS is a distributed system that (1) analyzes sensor data received in real-time from flood defenses (dikes, dams, etc.) and (2) simulates dike stability, breaching and flood propagation. Computational modules are invoked by workflow-based expert scenarios ...

Mobile Internet GIS based Flood Warning and Information Systems

The recent flood disasters showed that available warning systems do not fully fulfill their requirements and potentials. This paper examines these regarding web-based and mobile GIS based flood information and warning systems. We present first prototypes that are being developed at the University of Applied Sciences Mainz for a pilot area at the Rhine and give an outlook on the state of art and...

Hybrid Community Participation in Crowdsourced Early Warning Systems

In this paper we present Aurorasaurus: a website, a mobile application, and a citizen science initiative that allows a community of users to report and verify sightings of the Aurora Borealis. Through ad-hoc data indirectly offered through social media, a community of citizen scientists verify sightings of the Aurora Borealis. These verified data are tested against currently existing aurora-for...

An Integrated Simulation and Distribution System for Early Flood Warning

This research presents an integrated system of computer software, networking and web-based display developed and deployed to allow drainage management authorities immediate access to results from the Weather Research and Forecasting (WRF) Hydrological Extension model, WRF-Hydro. Output data from the model are analyzed by a chain of GIS, database and web publishing tools to forge updated and rea...
