A FOSS approach to
Integrated Water Resource Management.
The case study of Red-Thai Binh rivers system in Vietnam

The IWRM paradigmThe IWRM paradigm
Integrated Water Resources Management
(IWRM) is a process which promotes the
coordinated development and
management of water, land and related
resources in order to maximise economic
and social welfare in an equitable manner
without compromising the sustainability of
vital ecosystems. (...)

How to manage all this information and data?

IMRR GeoportalIMRR Geoportal
The Geoportal allows to
visualize, analyse and compare
different planning alternatives for the management of
the Red River water system in Vietnam, as a result of
the Multi Criteria Decision Analysis
methodology applied in the IMRR project.
How to manage all this information and data?

Multi Criteria Decision Analysis

Geoportal functionalitiesGeoportal functionalities
Time series visualization and analysis:
22 model components (reservoirs, gauge stations,
diversions..)
Water level, flow, rainfall timeseries related to:
– Historical data
– Unregulated reference simulation
– Reservoirs management alternatives simulation,
computed for different scenarios:
• Standard inflow
• Climate change inflow

Alternatives effects estimation:
criteria and indicators
Project hierarchy identify 5 sectors;
24 indicators, computed for:
– for the reference timeseries: BAU and unreg
– for each management alternative and each scenario
– related to specific components/location
Different temporal frequency:
– daily
– yearly
– horizon

Management alternatives simulation
Geoportal is connected with a lumped model of the
whole system, written in Octave:
– Custom period and inflow inputs definition;
– On demand update of all variables and
indicators;
– Drupal-based user interface to simulator
– Simulation results integrated inside geoportal

Why a CMS ?
Administration: user account, permissions and
roles
Extendibility: modules or plugins
Data and content management: organize,
structure, find and re-use content

Previous experience
Most popular, well documented, large community
CMS between joomla and wordpress
More advanced geospatial functionalities
(Geoserver and OpenLayers modules)
Why Drupal ?

How we manage geospatial data
using Drupal?

Drupal PostGIS and GDAL Modules
 GDAL: Read and import vector data in all formats
supported by the GDAL/OGR library.
 PostGIS: This module provides a field for
geospatial data that can be added to entities.
https://www.drupal.org/project/gdalhttps://www.drupal.org/project/postgis

Drupal Geoserver and Openlayers Modules
 Connect with Geoserver via url
 Define a workspace
 Add and manage layers
 Add and manage layers styles
 Publish Drupal data using the PostGIS
module.
 Seamless user authentication.
Add marker manually
: Add content/ Add
marker ->create point with
Openlayers editor
User case
https://www.drupal.org/project/geoserver https://www.drupal.org/project/openlayers
 Add, edit and manage layers
 Add and manage maps (OpenLayers
instances)
 Add and manage map projections
 Add and manage map styles
 Add behaviors – Clustering Behavior

IstSOS Management from Drupal
Connect with a istSOS installation via url
Associate a content type with the istSOS module
Add a service in the IstSOS service and set the EPSG
code
Choose a service from a list of already connected
services
Add observed properties
Add the units of measure of a property
Upload observational data ( all types of files)
https://www.drupal.org/sandbox/istsos/2149739
Add (associate) time series
data (observations) to the
marker: Add content/import
observations from csv file
User case

Final Remarks
IWRM in real world case study: huge amount of data, that need to be organized,
stored and accessible
Open Source: no lock-in and portability of the results (i.e. torough Virtual
Machines)
CMS to manage different user: decision makers, analyst, stakeholders, general
public
Stardard and well-known technologies adopted: Drupal, Geoserver, D3.js,
PostGIS, Gdal..
New module developed to implement IstSOS management trough Drupal
