5 Working Groups; WG2 works on measuring approaches
Compare and evaluate methods and techniques towards
standardized protocols for field based quantitative appraisal of connectivity in:
o Hydrology o Sediment Transport o Landscape Structure (Topography & Roughness)

The first Think Tank Meeting was hold in the University of Lleida, Catalunya, Spain (December 2014; see summary in www.connecteur.info)
(i) can we use new and perhaps more consistent terminology to describe connectivity?
(ii) feedbacks between structural and functional connectivity
(iii) how we should measure connectivity?
(iv) define new parameters we could measure in an ideal scenario that could provide new insights into connectivity

In order to measure connectivity we should consider:
First (A), measure structure, the potential for a landscape or ecosystem to be connected, or the emergence of form from process;

In order to measure connectivity we should consider:
First (A), if we measure structure, this is the potential (for a landscape or ecosystem) to be connected, or the emergence of form from process;
Second (B), we need to measure fluxes, alongside change
to the structure, in order to quantify feedback and thresholds which are intrinsic to the understanding of connectivity; and
Finally (C), we would ideally connect sources to sinks (or outlet fluxes) via physical tracing of water or/and sediment particles, to establish that both the structure that emerges and the fluxes that are measured are actually linked over the timescale of observation.

es V. PREPARING CONFERENCE
TALKS AND PAPERS
All outcomes of our ThT Meeting have been the bases for
conference talks.
These outcomes were briefly introduced in the EGU in 2015.
A review paper is in preparation. A first draft will be available soon.
Ok … based on what we explained before in terms of main discussions of our ThT, how we are reviewing if we can or we cannot measure connectivity?

Second, what are the available methods?

Finally, how can we integrate this at multiple spatial and temporal scales?

Our interactions have been based on: 1. Participating in ThT meetings (WG4 & 5) 2. Organising Training School/Workshops Together with WG4 Sediment And Water Connectivity In Mountain Drainage Basins Summer 2016 A first draft of the contents is ready (more during these days, see WG4 presentation) 3. Linking Field Meetings with WG2 objectives

VI. INTERACTING WITH OTHER WGs
We have created a document containing different questions that everyone organising a Field Meeting would need to answer. These answers will help in linking the Field Meetings with the activities WG2 is developing.
