Other elements

Completing CatchIS capabilities

CatchIS contains a range of other optional features which may prove of interest:

Climate change data

Future impacts on catchment management

This optional element allows the user to substitute the current climatic data that drives the models for future climate scenario data derived from the UKCIP02 emission scenarios (UK Climate Change Impacts Panel) This enables users to assess possible changes in water quality that may result from future climate change, although land use is assumed to remain the same.

A number of relevant IPCC climate change scenario datafiles can be selected in CatchIS model runs - here the 2020 low distributed dataset.

LEACS - Leakage and shrinkage

Underground Asset Management Planning (AMP)

Another optional element of CatchIS is the LEACS "Leakage and Corrosivity and Shrinkage" modelling suite, designed for operational AMP. This gives an assessment of ground conditions that could affect buried assets. There are two basic components, corrosivity and ground heave and for the former, both ferrous iron and zinc modules exist.

CatchIS 'Leacs' allows assessment of ground conditions as affect buried assets - here for corrosivity to ferrous materials (pipes and joints) - useful for AMP planning.
