Flood prediction using remote sensing and simplified mathematical modeling
Abstract
Riverine floods of above average stage and duration occurred along the Snake and the Teton Rivers in southeastern Idaho during late spring and early summer 2011. Compared with the 2010 floods, river stages were similar in many locations, although some stations reached record heights in 2010 while others reached record heights in 2011; in contrast, the duration of flooding in 2011 was unprecedented. Methods of remote sensing and simplified mathematical modeling are used to better quantify the potential flood events. Data from reservoirs, USGS gauging stations, SNOWTEL stations, aerial photographs, and multi-month Landsat imagery are used to quantify the snow extent during the 2011 flood season. The prediction model uses discharge data from previous years to test the results. Recent Landsat images and ENVI software is being used to analyze the multispectral Landsat images; ArcGIS software is being used to reclassify imagery, compare and contrast the data. Successful use of our prediction methods can help reservoir managers better plan for future flood events in the Snake River Plain.
