| Stormwater & Erosion Control Update |
| Welcome to this special Water Online newsletter, focused entirely on stormwater and erosion control. Today we're featuring a case study about how the Kentucky D.O.T. used turf reinforcement mats for its erosion control needs; another case study about pollution control using continuous deflective separation; an article about using modeling software to survey urban drainage systems and floodplains; and a variety of reference, product and downloadable material. |

Kentucky Department Of Transportation Uses Reinforced Filter Strip BMP To Enhance Storm Water Quality
In 2002, the Kentucky Department of Transportation (KDOT) determined a need to widen the highway known as Paris Pike that runs from Lexington to Paris, Kentucky. Preserving the natural beauty of the state's rural horse farms was a high priority during the project. KDOT wanted green shoulders, and a green median, but they also needed surfaces that could meet tough performance standards. Pyramat® high-performance turf reinforcement mat from Propex provided the ideal solution... |

YSI
Multiparameter Instruments Assist In Storm Water
And Combined Sewer Overflow Monitoring
The city of Indianapolis, Indiana has been
monitoring surface water quality of the White
River and its tributaries since 1991. Each year
the Indianapolis Office of Environmental Services
collects nearly 6,000 samples from 27 locations.
Two specialized programs, Continuous Dissolved
Oxygen and Critical DO, are designed to collect
data during periods when the potential exists for
dissolved oxygen problems. YSI multi-parameter
monitoring equipment is currently deployed at
seven sites on the White River and its
tributaries, where monitoring dissolved oxygen
levels is the focus... |

Stormceptor
Assists The Port Of Los Angeles' Berth 100 Wharf
And Container Terminal Project
Located in San Pedro Bay the Port of Los Angeles
is America's leading cruise terminal on the west
coast and its busiest container port, moving a
record breaking 5 million marine cargo containers
in November 2001 alone. To enhance the existing
terminal's efficiency, the Board of Harbor
Commissioners moved ahead with the construction of
Berth 100 Wharf and Container Terminal located in
the West Basin area of the Port, former home to a
Chevron Marine Terminal and Todd Shipyard which
closed in the early 1990s. Stormceptor was
subsequently chosen as the preferred BMP to
satisfy both the specified treatment and submerged
criteria... |

Continuous
Deflective Separation Eliminates Floatables And
Gross Pollutants From Santa Monica Storm Water
The City of Santa Monica, Calif., always has
fought proactively against pollution, especially
when it threatens its world-famous beach and bay.
As a result, the city has experimented with a
number of pollution-control technologies.
"Nothing has worked really well in the
past," explains Craig Perkins, the city's
director of environmental and public works
management. "The available technologies have
been maintenance nightmares, and floatables still
got into the bay." Several years ago, the
city decided to construct a facility near its pier
to capture and treat flow from the stormwater
system... |

1D
And 2D Modeling Of Urban Drainage Systems Using
XP-SWMM And TUFLOW
The release of a revised NSW Floodplain Management
Manual in 2001 established a new direction for
urban flood management in NSW. This new direction
was created by a redefinition of the floodplain as
the area bounded by the PMF – this poses a
challenge to estimate PMF flooding in highly urban
areas and particularly in piped drainage areas;
and the removal of the distinction between
"mainstream flooding" and "local
flooding" – this poses challenges in
defining and mapping flood risk areas in
residential areas inundated by the PMF... |

Stormwater
Management For Smart Growth
By Allen P. Davis and Richard H. McCuen
Issues related to the management of stormwater runoff from developed areas are rapidly changing. First-generation stormwater management focused on providing flood protection and limiting peakflow, whereas now a greater emphasis is being placed on water quality. Accordingly stormwater management is shifting, with more emphasis on treatment practices and devices to improve stormwater quality to protect against stream, river and estuary degradation... |
