MAR Suitability Mapping

MAR suitability mapping Leaders:  Jose Bonilla (AyA Costa Rica) and Catalin Stefan(TU Dresden)

This is a newly formed working group at IAH-MAR at 45th IAH Congress, Daejeon, September 2018 whose initial membership includes Arnaud Sterckx (IGRAC), Daniel Goode (USGS), and Jana Sallwey (TU Dresden), and seeks to grow by being joined by all those with an interest in this topic.

It seeks to Initiate a network of scientists and stakeholders to share experiences on MAR suitability
maps (criteria, scales, objectives, applications etc.)

It will evaluate the range of methods in use, many of which are multi-criteria analysis of mapped
parameters, each with a range indicative of suitability and with a weighting factors. There is
considerable subjectivity and apparently inconsistent methodology for GIS-based selection of suitable
sites for MAR. The group will consider primarily hydrogeologicical suitability and also availability of
source water and demand for water. Maps have different purposes, scale, and are based on a range
of data types and densities, and there are different requirements for different MAR methods. There
will be an effort to put this onto a scientific footing, which may result in different types of maps under
different settings, but useful for the purpose intended, able to be validated, and ideally also capable
of international comparison.


As a starting point an initial review paper is : Sallwey et al. 2018. Suitability maps for managed aquifer
recharge: a review of multi-criteria decision analysis studies. Environmental Reviews, accepted

A workshop will be held at ISMAR10 to allow the dialogue to be progressed and specific targets set for
the outputs of the working group.

Volunteers are invited to inform Jose and Catalin of their interest, whether they
have case studies, concerning the existence of such maps in their country to send him the
web link or a copy to add to those on the web site. Volunteers may receive a copy of the
paper when published, and can contribute to formation of the ISMAR10 workshop.
