ABSTRACT: This paper presents a proposal for erodibility
quantitative evaluation through a hydraulic
flume based on the Inderbitzen erosion test. The equipment scheme and
procedures for result calculation are described, following a review of
literature. Through the proposed procedure, 24 tests are conducted, in order to study the erodibility of a sandy soil
and a clayey soil, in undeformed and reconstituted conditions. These are
conducted using grass roots in controlled quantities, to quantify root effects
on erodibility. The results of soil loss by elapsed time and the definition of
the erodibility K factor shows that clayey
soil is 90% less erodible compared with sandy soil. Also, roots show no
significant relationship with K factor and the undeformed sample is less
erodible, compared with reconstituted sample. The test methodology and the
results allowed soil classification, analytical data and comparative results
between different cases.
