Adapted From: FHWA, HEC- 15, April 1983, pgs. 17 & 37,
Design Procedure- The following is a step-by-step procedure for designing a temporary liner for
Temporary Liners a channel. Because temporary liners have a short period of service, the design
Q may be reduced. For liners that are needed for six months or less, the 2-year
frequency storm is recommended.
Step 1. Select a liner material suitable for site conditions and application.
Determine roughness coefficient from manufacturer's specifications or Table
8.05e, page 8.05.10.
Step 2. Calculate the normal flow depth using Manning's equation (Figure
8.05d). Check to see that depth is consistent with that assumed for selection of
Manning's n in Figure 9.05d, page 8.05.11. For smaller runoffs Figure 8.05d
is not as clearly defined. Recommended solutions can be determined by using
the Manning equation.
Step 3. Calculate shear stress at normal depth.
Step 4. Compare computed shear stress with the permissible shear stress for
the liner.
Step 5. If computed shear is greater than permissible shear, adjust channel
dimensions to reduce shear, or select a more resistant lining and repeat steps
I through 4.
Design of a channel with temporary lining is illustrated in Sample Problem
8.05b, page 8.05.14.

Operation and Maintenance Agreement
I will keep a maintenance record on this BMP. This maintenance record will be kept in a
log in a known set location. Any deficient BMP elements noted in the inspection will be
corrected, repaired or replaced immediately. These deficiencies can affect the integrity
of structures, safety of the public, and the removal efficiency of the BMP.
Important maintenance procedures:
- Immediately after the filter strip is established, any newly planted vegetation
will be watered twice weekly if needed until the plants become established
(commonly six weeks).
- Once a year, the filter strip will be reseeded to maintain a dense growth of
vegetation
- Stable groundcover will be maintained in the drainage area to reduce the
sediment load to the vegetation.
After the filter strip is established, it will be inspected quarterly and within 24 hours
after every storin event greater than 1.0 inch (or 1.5 inches if in a Coastal County).
Records of operation and maintenance will be kept in a known set location and will b,4
available upon request.
Inspection activities shall be performed as follows. Any problems that are found shall
be repaired immediately.

Operation and Maintenance Agreement
I will keep a maintenance record on this BMP. This maintenance record vs7i-1 be kept in a
log in a known set location. Any deficient BMP elements noted in the inspection will be
corrected, repaired or replaced immediately. These deficiencies can affect the integrity
of structures, safety of the public, and the removal efficiency of the BMP.
Important maintenance procedures:
— Immediately after the filter strip is established, any newly planted vegetation
will be watered twice weekly if needed until the plants become established
(commonly six weeks).
— Once a year, the filter strip will be reseeded to maintain a dense growth of
vegetation
— Stable groundcover will be maintained in the drainage area to reduce the
sediment load to the vegetation.
After the filter strip is established, it will be inspected quarterly and within 24 hours
zfter every storm event greater than 1.0 inch (or 1.5 inches if in a Co o
astal Cunty).
Records
• operation and maintenance will be kept in a known set location and wi 13,

Inspection activities shall be performed as follows. A-ny problems that are found shall
be repaired immediately.
