By Mike Vaughan Spectators from around the globe have been watching the London 2012 Olympic and Paralympic Games, enthralled by world-class athletes participating in stunning competitions. It’s a safe bet to imagine that few in the crowd have thought about flooding, though flood safety was an essential factor in the creation of the new Olympic Park, site of Olympic Stadium and numerous other competition venues. To keep floodwaters controlled, 2 miles of riverbanks were redesigned and reengineered...... continue reading

Rahr Malting Co., located in Shakopee, MN, is one of the largest malt producers in the United States. In 1997, Rahr requested permission to build its own wastewater treatment plant and withdraw from the regional sewer system. The Minnesota Pollution Control Agency (MPCA) denied this request because a total maximum daily load (TMDL) established in 1988 had allocated the entire available discharge load for the lower Minnesota River to existing treatment facilities. To solve the regulatory deadlock, an inn...... continue reading

The City of Austin’s (COA’s) Watershed Protection Department (WPD) engineers and scientists use a multitude of tools to analyze trends and evaluate possible methods to remedy and minimize environmental impacts, such as flooding, erosion, and water-quality degradation due to development. Traditional methods usually analyze the impacts of extreme events at certain points in time, yet WPD is also interested in more long-term effects. Needless to say, different applications require different analysis method...... continue reading

The hydrologic cycle is an interwoven network of dynamic equilibria of water in all its physical states driven by the Sun. The incoming solar radiation is all the energy available to cycle water through the air, land, and plant life by technology of the green leaf. An exploratory evaluation of the natural state and energy balance of the landscape sets up a framework for design, management, and operation of a comprehensive stormwater system in an urbanized landscape. The evaluation focused on natural vege...... continue reading

The aim of this article is to encourage more use of native vegetation in our land-use practices. This encouragement takes the form of soil water retention and infiltration predictions for prairie vegetation (more than three years old) and forests (more than five years old) based on soil texture class and bulk density. These predictions are databased and describe the central tendencies of soil water properties in the upper soil column of native landscapes almost as well as established literature values d...... continue reading

A Gathering Storm Proprietors of summer rentals converge on city offices, seeking redress as scourges of jellyfish drift towards the beach, frightening vacationers from seaside resorts. Watermen stand by helplessly, witnessing a shocking decline in their catches in areas that, until recently, were teeming with shellfish. Homeowners recoil at the prospect of venturing into their own backyards, terrified of the thick clouds of mosquitoes that infest their suburban neighborhoods. No, these are not scenes f...... continue reading

Some parts of the Chesapeake Bay are pristine, but other sections are so full of silt and runoff that they appear muddy even at ground level. Years of unregulated agricultural runoff, the growing amount of impervious surface from suburban sprawl, and the bureaucracy of several states intertwined with their own interests are the main reasons for the decline of the Chesapeake. The Chesapeake’s watershed covers 64,000 square miles. That territory includes large and small cities, suburbs, farmlands, forests...... continue reading
