A flood is an overflow of water that submerges land which is usually dry. The European Union (EU) Floods Directive defines a flood as a covering by water of land not normally covered by water. In the sense of “flowing water,” the word may also be applied to the inflow of the tide. Flooding may occur as an overflow of water from water bodies, such as a river or lake, in which the water overtops or breaks levees, resulting in some of that water escaping its usual boundaries, or it may occur due to an accumulation of rainwater on saturated ground in an areal flood. While the size of a lake or other body of water will vary with seasonal changes in precipitation and snow melt, these changes in size are unlikely to be considered significant unless they flood property or drown domestic animals.

Techniques for Stabilizing Slopes

Techniques for Stabilizing Slopes

From stabilizing failing slopes to creating new slopes, erosion control contractors are turning to new technologies as well as relying on the tried and true in a number of projects throughout the US.

Protecting Drinking Water from Saltwater Intrusion

In Miami Beach, FL, people sometimes must navigate streets wearing boots because during weather events, the streets get flooded twice a day for a couple of hours, notes Jayantha Obeysekera, chief modeler for the South Florida Water Management District (SFWMD).

New York field study will help target relief, document shoreline changes

Beginning July 10, US Geological Survey scientists plan to conduct fieldwork along a flood-impacted stretch of New York’s Lake Ontario shoreline, using unmanned aerial systems (also known as drones), pressure sensors that measure water elevation and special water-elevation gages designed

Foliar Rainfall Retention

Foliar Rainfall Retention

Trees and forest systems play an important role in the water cycle by intercepting rainfall and regulating water flow to the soil for more efficient stormwater infiltration. Traditional urban development practices have reduced the function of these systems by eliminating the vertical structure (tree canopy cover), removing existing ground cover

Strengthening Shorelines With Hard Armor

Perhaps the slopes are too steep. Perhaps the current is too strong. Perhaps both, and maybe some other challenging site conditions exist as well. Some projects along bodies of water require extra-strong measures to stop erosion. One of those projects is in Idaho.

It was in June 2013 that the 3,200-acre Royal Gorge fire broke out near Cañon City, CO, situated about 45 miles southwest of Colorado Springs. The wildfire destroyed almost everything in its path (48 out of 52 structures in Royal Gorge Park were lost), although surprisingly it spared the Royal

Editor’s Comments: Afraid of the Water

It’s hurricane season—june through november—and although we might not give it much thought if we don’t live near the eastern seaboard or gulf coast, progress in how people are predicting and reacting to hurricanes have some implications that extend far inland.

Water flow is something old, new, blue

Just ahead of a rainstorm, Cody Ross might run out to an agricultural research site as part of his graduate work. He’ll need to get some dye into an injection well. The point? To evaluate the path that water follows from the field
