Pimentel et al say:
oil erosion is a major environmental threat to the sustainability and
productive capacity of agriculture. During the last 40 years, nearly one-third
of the worlds arable land has been lost by erosion and continues to be lost
at a rate of more than 10 million hectares per year. With the addition of a
quarter of a million people each day, the world population's food
demand is increasing at a time when per capita food productivity is beginning

To protect the environment effectively and economically, use Dirtbags®
whenever accumulated water must be pumped. Dirtbags filter water before it is
discharged, removing silt and sediment. As more and more emphasis is put on
saving our wetlands, regulations are becming more and more stringent regarding
the pumping of didty water.
Scientists from San Diego State University's Soil Erosion Research Laboratory conducted in-depth testing on
Earth Savers Rice Straw Wattles and found that they dramatically reduced
downslope sediment delivery — by 58 percent for the 9" diameter wattles, and
by 74 percent for the new 20" wattles. In fact, the 20" wattle has proved to
reduce sediment delivery by 84 percent after three consecutive rainfall
events. The laboratory's Rainfall Simulator Testing also demonstrated that
Earth Saver wattles reduce runoff water velocities and release water at a
steady rate. Wherever bare soil is exposed to erosion by wind or water, Earth
Saver Rice Straw Wattles can be an important part of a comprehensive Best
Management Practice system for soil stabilization, sediment retention and

Geotextiles have replaced graded
granular filters used beneath riprap or other armor materials. Typical
applications include drainage channels, shorelines, river, coastal protection,
canals, and bridge and pier scour protection systems. The effective control of
destructive erosion in shorelines, riverbanks, drainage ditchres, and canals
has always posed a difficult problem. This stems from the need for a robust
outer protective layer to absorb the energy of wave or current, and an inner
protective layer, traditionally in the form of an aggregate filter to prevent
erosion of the bank soil. This inner layer has a particularly difficult role
to play, since it must fill the often conflicting requirements of being fine
enough to act as a bank soil filter, yet coarse enough to prevent the
generation of high differential pressure between the bank and external water
levels. These problems are overcome with properly designed
filter fabric installed to cover the exposed surface of the bank. The
selection of geotextiles used in shoreline erosion control requires
consideration of filtration mechanisms, installation stresses, and long-term
durability requirements. Filtration mechanisms will rely on the gradation of
the soil, pore size characteristics of the geotextile, and water flow
conditions. While design criteria have been well established for geotextile
filters, the special nature of erosion control applications must be carefully
considered in selecting the most appropriate geotextile for the specific site
conditions. The design relations are complicated by the reversing flow
conditions that exist in coastal erosion control applications.
Grass Mulch is a natural grass straw fiber mulch, produced byGrass Fiber, Inc. @ (541) 998-3261
using clean grass seed straw from certified grass seed fields. Grass
Mulch is disc refined and heat processed in such a manner to contain no
growth or germinating factors. Grass Mulch disperses rapidly in water and
remains in unform suspension under agitation. It blends with seed, fertilizer
and other approved and specified materials to form a homogeneous slurry. When
applied by hydraulic means to ground surfaces the fibers will physicaly
intertwine to form a strong moisture holding mat that will assist soil erosion
control and provide percolation as well as favorable micro-climate conditions
to aid seed germination and growth. The fibers are clored green with a water
soluble non-toxic dye to assist the operator in applying Grass
Mulchuniformly. The dye will not stain concrete, asphalt, masonry or
painted surfaces. The Turf Mulchis commonly used in a dry roll on
application as a top dressing for newly seeded lawns.

In a Slope
Stabilization application, for any given soil at a certain moisture
content, there is an angle beyond which the soil will not stand without some
kind of support. Whenever the steepness of the slope exceeds this failure
angle, gravitational forces act on the soil mass to create shear stresses
causing the slope to fail through sliding or sloughing off. The process ends
when a new equilibrium is achieved at an angle less steep than the initial
one. In many situations, it is desirable to have a slope steeper than the
shear strength which the soil will allow. One method employed to achieve this
objective to provide reinforcement at specified increments back into the
slope. The resulting reinforcement increases the effective failure angle,
preserving the stability of the slope.

slopes denuded by fires and timber harvest. Straw Wattles are used by
the Federal Highway Administration, National Forests, State Highway
Departments, State Park & Recreation Departments, CA Dept. of
Conservation-Division of Mines and Geology, Resource Conservation Districts,
and City & County governments. Straw Wattles last 3 to 5 years and
can be left in place. They replace silt fences, straw bales, earth berms,
willow wattles, sandbags, and earth water-bars. Used with tacked straw they
are an efficient and cost effective replacement for erosion control blankets.

"Providing Maximum Erosion Protection through Vegetation Establishment"
Retaining walls are structures built for the
purpose of stabilizing very steep slopes using minimal land area. A common
example is to infill the side of a hill to build or widen a road. The slope
created is so steep as to be unstable and requires a retaining wall to prevent
slope failure retaining walls.
There are two basic types of retaining walls: A CANTILEVER retaining wall is usually made of
reinforced concrete and acts as a structural member. A GRAVITY retaining wall has a vertical or near
vertical face and its ability to retain soil behind it depends upon gravity
(its own weight). This type of wall is usually composed of unreinforced
concrete or soil. If made of soil, the wall generally consists of a facia and
one or more layers of reinforcing members extending from the facia back into
the soil mass. The functions of the facia are to prevent soil from
sloughing off the surface of the wall and to prevent erosion of the face of
the wall. The function of the reinforcing member (TerraGrid)
is to increase the "effective" thickness of the wall which increases its
stability. The wall itself must be built to withstand pressures applied
by the retained soil. This force, "lateral earth pressure', is dependent upon
several parameters, including the geometry of the wall and the characteristics
of the retained soil, such as its unit weight and angle of internal friction.
In designing a retaining wall, it is necessary to consider potential forces
that could cause wall failure and compare them to the stability calculations
of the proposed wall, taking into account generally accepted safety
