A pipeline carrying natural gasoline developed a leak over the weekend, with the potential to lose about 140,000 gallons of gasoline in the Missouri River floodplain southwest of Onawa. Continue reading →
As floodwaters on the Missouri River move relentlessly toward Iowa’s western border, scientists at the Iowa Flood Center (IFC) are making plans to study the water’s movements. Most of the western edge of the state faces the threat of flooding from the Missouri in the days and weeks ahead.
Iowa Flood Center Director Witold Krajewski says the IFC is planning to take aerial photographs of the flooded areas this week, collaborating with the University of Iowa’s Operator Performance Laboratory (OPL), which will fly one of its instrumented aircraft, a Beechcraft A-36 Bonanza, to conduct the photography sessions. The high-resolution photography, combined with statewide LiDAR (laser radar) data already available, will allow researchers to delineate the boundaries of inundated areas and compare these with existing floodplain maps. The improved maps will help Iowans know what to expect during future floods.
“We hope to take the photos at the peak stage of the flood,” Krajewski says. “The results will be extremely valuable as we continue to develop floodplain maps, which are useful for planners and property owners.” Continue reading →
