As lingering spring rains soak eastern Iowa, crews from the U.S. Geological Survey continue efforts to make sure the streamgaging network is providing basic scientific information needed by water-resource managers and the community.
New survey by flood report service, RiskCentral, reveals a lack of awareness around the issue of surface water flooding. The flood risk report service, RiskCentral.co.uk, has just published the results of their consumer survey concerning the risk posed by different types of floods.
The World Water Online (WWO) group in the ArcGIS Resource Center has 12 new web map applications based on the SSURGO soil survey database. These apps show soil characteristics that are useful for hydrologic modeling, such as drainage class, available water storage, water table depth, and ponding frequency. The hydrologic group code, which classifies soils based on infiltration rate, can be used to calculate curve number and model how much rain falling in an area will become runoff. Read More
A new model to better describe groundwater changes and chloride movement in the Equus Beds aquifer, a primary water-supply source for the Wichita, Kansas area, has been completed by the U.S. Geological Survey, in cooperation with the City of Wichita.
U.S. Geological Survey field crews are measuring record flooding on rivers and streams across most of Illinois. At least ten USGS streamgages in Illinois that have more than 20 years of record, have measured the highest flood levels ever recorded. More record levels are expected as flooding moves downstream. USGS crews are expected to track the movement of the floodwaters down the Illinois River, the Rock Rivers, and major tributaries over the next few days. Many of the Illinois River floodwaters are expected to exceed records and may result in major flooding that overtop levees. There are 53 USGS streamgages currently at or above flood levels as a result of the rains that began on Tuesday, April 16.
