A serious gaming framework for decision support on hydrological hazards

In this study, a web-based decision support tool (DST) was developed for hydrological multi-hazard analysis while employing gamification techniques to introduce a competitive element. The serious gaming environment provides functionalities for intuitive management, visualization, and analysis of geospatial, hydrological, and economic data to help stakeholders in the decision-making process regarding hydrological hazard preparedness and response. […]

Hydrology@Home: a distributed volunteer computing framework for hydrological research and applications

Web-based distributed volunteer computing enables scientists to constitute platforms that can be used for computational tasks by using potentially millions of computers connected to the internet. The framework provides distribution and scaling capabilities for projects with user bases of thousands of volunteers. As a case study, we tested and evaluated the proposed framework with a […]

A Rainfall‐Runoff Model With LSTM‐Based Sequence‐to‐Sequence Learning

Researchers have been developing physical and machine learning models for decades to predict runoff using rainfall data sets, and this study presents an application of a prediction model based on LSTM and the seq2seq structure to estimate hourly rainfall‐runoff. LSTM = Long Short-Term Memory seq2seq = sequence to sequence modeling

Crowdsourced approaches for stage measurements at ungauged locations using smartphones

Citizen science opportunities for environmental monitoring have increased with the advances in smart phone capabilities and their growing availability. This project describes a new method to accurately measure river levels using smartphone sensors. Pictures of the same point on the river’s surface are taken to perform calculations based on the GPS location and spatial orientation […]

A collaborative serious game for water resources planning and hazard mitigation

Hydrological hazards are enormous risks for communities. A Multi-Hazard Tournament (MHT) allows members of a watershed community to evaluate adaptation options to develop mitigation strategies for multiple water-related hazards such as floods, drought, and water pollution. Hazard risk assessment and minimization of water quality issues and water resources are all parts of the plan.

Revisiting hysteresis of flow variables in monitoring unsteady streamflows

Steady and unsteady streamflows are monitored through combining direct flow measurements and statistical analyses. Flow variables displaying inherent hysteretic behavior is indicative of non-kinematic waves passing through the gauging station. The paper demonstrates the index-velocity and continuous slope-area methods are more suitable to monitor unsteady flows in comparison with the widely used stage-discharge approach.
