Abstract

Modeling river behavior in software is essential to increase the lifetime of hydraulic structures, while protecting surrounding communities from flood and ice jam events. This research focuses on defining a novel methodology to collect and analyze river discharge, geometry, and landcover data, providing rural communities with a method of modeling river behavior. This includes the collection of critical river information that is not available to the public, and the process for surveying or interpolating geometric constraints. The methodology for modeling rivers in software shows strong correlation with historical data, capturing the full geometry of the river and those structures that lie in its channel with an overall volume accounting error of less than 0.01%. Model capabilities will provide communities with the ability to produce inundation maps during a flood and have disaster relief services in place before weather events occur. Additionally, by using meteorological data in conjunction with the model for a watershed, communities and stakeholders have the ability to predict the onset of ice-jam events when temperatures decrease. This provides people that lie within major watersheds the ability to predict the rapid accumulation of ice jams and onset of flood events before they happen.
