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 web-based decision support system for collaborative mitigation of multiple water-related hazards using serious gaming

The paper focuses on a participation-based serious gaming application developed to enhance multi-jurisdictional collaborative planning and decision making for mitigation of multiple hazards related to water, such as flooding, soil erosion, and water quality. The game is integrated into the Iowa Watershed Decision Support System (IoWaDSS).

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.

Development of Synthetic Rating Curves: Case Study in Iowa

The authors of the case study discuss an economically feasible approach to generate synthetic rating curves that enhance utility of stage-only river gauges. There are 250 bridge-mounted river-stage sensors deployed by IFC in Iowa. Those sensors, in concert with USGS and other related sensor data, are used to determine discharge and other errors or triumphs […]
