downloaded along with the user manual. Whilst
the majority of the links are valid and the site is
a useful starting point for finding out what
models exist, there are some links which are out-
of-date and either do not work or are no longer the
most appropriate. Clearly no such site can be fully
comprehensive, and there will inevitably be some
models which are not included. Table 1.1 lists the
models which are used in this Handbook together
with details of published sources and, where they
exist, relevant Internet sites. Knowing which
models are available is only a starting point. As
indicated above, the user needs advice on how
well the models perform and the conditions to
which they can be applied. Previous experience
with the models is extremely valuable, particu-
larly where the output of several models is com-
pared for the same conditions. Boardman and
Favis-Mortlock (1998) discussed the performance
of various models when applied to common sets of
data at a hillslope scale, and De Roo (1999) pre-
sented the results of a similar exercise carried out
at a small catchment scale. More recently, Harmon
and Doe (2001) provided details of a range of mod-
els, physically-based and empirical, which can be
used over various spatial and temporal scales to
assess the short- and long-term effects of different
land management strategies. These publications,
however, describe erosion models more from a
research than a user perspective. Although they
are a source of useful information, they do little to
help potential model users to answer the ques-
tions raised earlier, or to guide them in the selec-
tion of the most appropriate model for a specific
application, taking account of the objectives, the
environmental conditions and the availability of
data. Also, since their publication, there has been
an increasing use of geographical information sys-
tem (GIS) techniques in analysing data for plan-
ning and decision-making, and erosion models
have been increasingly integrated into geospatial
systems, particularly at large catchment and
regional scales.
The
Handbook of Erosion Modelling
seeks to
address these issues and provide the model user
with the tools to evaluate different erosion models
and select the most appropriate for a specific pur-
pose, compatible with the type of input data that
are available. The topic is aimed at model users
within government, non-governmental organisa-
tions, academic institutions and consultancies
involved in environmental assessment, planning,
policy and research. The intention is to give exist-
ing and potential model users working in the
erosion control industry greater confidence in
selecting and using models by providing an insight
