1.1 Background
1. Freshwater is an essential and finite resource; adequate quantity
and quality are crucial for sustainable socio-economic development in
every nation (Bartram and Ballance, 1996).

2. Planning and monitoring schemes are required to regularly check the
quality and quantity of our water bodies in our cities, towns and villages
(Loucks et al., 2005)
 3. Geo-information Science (GIS) and remote sensing techniques provide
 a unique opportunity to monitor and assess water quality in space and
 time

4. The availability of open source GIS tools and water quality models
provide another opportunity to reduce the cost of water quality modelling
of small rivers.

1.3 Rationale


1. Water quality modelling for small rivers has been
   given little attention compared to large rivers
   (Marsili-Libelli and Giusti, 2008)
2. Limitations of existing models for water quality
   modelling
3. Existing Capabilities of ILWIS Open

1.5 Objectives
To develop a GUI for handling water quality modelling in ILWIS Open
for the Dinkel River

  b. To identify an appropriate hydro-transport and water quality
  model for study area
  c. To couple these models together and integrate this finished
  model in ILWIS using a GUI
  d. To perform calibration and validation of this model
  e. To document a user’s guide manual for the GUI for water quality
  modelling

2.0 Methodology
2.1 Selection Criteria for Models
                      1. Must be open source models
                      2. Useful for practical applications

2.2 FEQ Model


The Full EQuations (FEQ) model is a computer program for
solution of the full, dynamic equations of motion for one-
dimensional unsteady flow in open channels and through control
structures. (Gordon, 1997)

Main Equation
 The two fundamental equation for unsteady flow simulation are
                               ∂Q      ∂y ∂Q 2
  •Momentum Equation              + gA   +     = gA( S 0 − S f )
                               ∂t      ∂x A∂x
                                     ∂A ∂Q
  •Continuity Equation                 +   =q
                                     ∂t ∂x

Gui for water modeling quality

  • 1. Developing a GUI for modeling the water quality of the “52°North” Dinkel river Interim Report Team Amos Kabo-Bah Zun Yin Supervisors: Chris Mannaerts, Suhyb Salama, Rob Lemmens, Martin Schouwenburg 52°North Student Innovation Prize for Geo-informatics November 24, 2009
  • 2. -Background 1.0 Introduction -Study Area -Rationale Outline of Presentation -Objectives -Selection Criteria for Models 2.0 Methodology -OTIS & FEQ Model -General Procedure 3.0 Preliminary Results 4.0 Work in Progress 52°North Student Innovation Prize for Geo-informatics November 24, 2009
  • 3. 1.1 Background 1. Freshwater is an essential and finite resource; adequate quantity and quality are crucial for sustainable socio-economic development in every nation (Bartram and Ballance, 1996). 2. Planning and monitoring schemes are required to regularly check the quality and quantity of our water bodies in our cities, towns and villages (Loucks et al., 2005) 3. Geo-information Science (GIS) and remote sensing techniques provide a unique opportunity to monitor and assess water quality in space and time 4. The availability of open source GIS tools and water quality models provide another opportunity to reduce the cost of water quality modelling of small rivers. 52°North Student Innovation Prize for Geo-informatics November 24, 2009
  • 4. 1.2 Study Area Basin area = 643sq.km Total length = 93km Elevation = 15m – 110m Rainfall = 750- 800mm/yr 52°North Student Innovation Prize for Geo-informatics November 24, 2009
  • 5. 1.3 Rationale 1. Water quality modelling for small rivers has been given little attention compared to large rivers (Marsili-Libelli and Giusti, 2008) 2. Limitations of existing models for water quality modelling 3. Existing Capabilities of ILWIS Open 52°North Student Innovation Prize for Geo-informatics November 24, 2009
  • 6. 1.5 Objectives To develop a GUI for handling water quality modelling in ILWIS Open for the Dinkel River b. To identify an appropriate hydro-transport and water quality model for study area c. To couple these models together and integrate this finished model in ILWIS using a GUI d. To perform calibration and validation of this model e. To document a user’s guide manual for the GUI for water quality modelling 52°North Student Innovation Prize for Geo-informatics November 24, 2009
  • 7. 2.0 Methodology 2.1 Selection Criteria for Models 1. Must be open source models 2. Useful for practical applications –discussion with Regge & Dinkel Water board FEQ 52°North Student Innovation Prize for Geo-informatics November 24, 2009

  • 9. 2.2 FEQ Model The Full EQuations (FEQ) model is a computer program for solution of the full, dynamic equations of motion for one- dimensional unsteady flow in open channels and through control structures. (Gordon, 1997) Main Equation The two fundamental equation for unsteady flow simulation are ∂Q ∂y ∂Q 2 •Momentum Equation + gA + = gA( S 0 − S f ) ∂t ∂x A∂x ∂A ∂Q •Continuity Equation + =q ∂t ∂x 52°North Student Innovation Prize for Geo-informatics November 24, 2009
