WISE main rivers

WFD-ECRINS matching and advances in linear referencing

Slide 2

Index

1. WISE main rivers2. WFD-ECRINS integration

– Our approach: integrating WFD reporting into ECRINS (why? Issues – canals; advantages: calculations – water accounts, cross-cutting)

– The method (history, new developments)– Transfer RIVER_CD screenshots

3. Dynamic segmentation process in detail– Advantages: routes reporting based on tables?

4. Future– Planning 2012: canals, groundwater

Slide 3

1. WISE Main Rivers

WISE main rivers are the main rivers reported by MS complying the WFD

The defintion of main rivers by WFD establishes a threshold of 500 sq.kms

Situation: map of the main rivers reported by MS we are working with:

(April 2012)

Slide 4

1. WISE Main Rivers

First version built in 2010

Refers to data reported until August 2010

New draft version: released in April 2012• New version contains

previous version plus new rivers

• Methodology for the new rivers had to be revisited as the previous is very difficult to maintain

(April 2012)

Slide 5

2. WFD-ECRINS integration

Our approach: integrating WFD reporting into ECRINS (why? Issues – canals; advantages: calculations – water accounts, cross-cutting)

WHY?ECRINS is a comprehensive, regular, connected database

AdvantagesCalculations and accounting (connected database: rivers + lakes + groundwater…)Cross-cutting !? First time to do it

Slide 6


The method (history, new developments)2 steps

Transferring Wfd River_cd into Ecrins

Transferring Wfd segments into Ecrins

Slide 7


The method (history, new developments)

History (How we did before)

New developments (Improvements)

Slide 8


The method

Outcomes:

• Main rivers below surface criteria remain main rivers

• Rivers not reported as main, above surface criteria COMM/EEA/ETC to contact MS

Slide 9


Select a segment and trace downstream

Slide 10


• Tributaries:select segments >500 sqkm flowing into a river

Slide 11


• ‘Identify” of the features

Slide 12

Identify the river to be found

Automation• Previous: tr_identity is identity of WFD main

river with FECs• Start with ECRINS final segment• Get TNODE value as to_node• Select C_Node where NodID = to_node• Find closest tr_identity (select by location,

250m), where exutoire = 1– get:

• CODE_ARBO• River_CD

3. Dynamic segmentation

Slide 15


Dynamic segmentation is the process of transforming linearly referenced data (commonly called ‘events’) stored in a table into a feature that can be displayed on a map

We will consider the WFD as the events and the ECRINS database as the routes

Slide 16


Dynamic segmentation process in detail: steps

Dissolve the rivers with the WFD id

River segmentationEach vertex of the route will have a new value with the distance from the starting point

Create waterbodiesWFD river segmenas are located into ECRINS main rivers

Slide 17


Dynamic segmentation: ADVANTAGES

Routes reporting based on tables

Dynamic information vs. Static information

If segmentation change in WFD: is OKIf new features are added in WFD: is

OK
