Wischmeier WH, Johnson CB, Cross BV (1971) A soil erodibility nomograph
for farmland and construction sites.
Examination of the nomograph
in Table II supports several ideas about the FSA designated amount.
Very interesting nomographs
, which may be used to calculate weld impact strength from said parameters, are presented for use by practitioners.
Table 4 shows the recommended speed of each curve based on the ball-bank indicator criteria and nomograph
in the TCDH, which is based on the standard curve speed formula with a friction factor of 0.16.
(2003) included the effect of hydrophobicity in the K factor, and assumed that a hydrophobic soil would have the lowest hydraulic conductivity accepted in the USLE soil nomograph
. As explained above, the K factor is precisely defined from unit plots where fire-induced hydrophobicity was absent, and it seems inadvisable to tamper with it by introducing corrective coefficients.
For soils containing [is less than] 70% silt plus very fine sand, the nomograph
of Wischmeier et al.
Usually the Soil Erodibiity Factor (K) factor can be attained from local Natural Resources Conservation Service offices, but the unique, inverted soil profile of the military earthworks caused us to determine K values from the standard nomograph
provided by Dissmeyer and Foster (1984).
For example, the soil erodibility nomograph
for the USLE does not seem to apply to many strongly structured soils found in the tropics (El-Swaify and Dangler 1976), although Loch and Rosewell (1992) showed that estimates of the erodibility parameter can be improved if wet sediment density and water-stable aggregate sizes were used instead of the density and sizes of primary particles as originally recommended (Wischmeier et al.
"So You're Going to Build a Water Storage Tank?" The author describes how water tank dimensions can affect water supply in storage and presents the use of a nomograph
for calculating storage volume from circular tank dimensions.
When this happens a very helpful nomograph
is given below.
This unusual nomograph
allows the design engineer to predict the ratio of effective radiated power (ERP) of an on-board jammer to a decoy jammer.
As illustrated in the figure, graph paper used for this purpose often contains a nomograph
on the righthand side of the chart and a "bull's eye" pattern nearby.
