Course Rural Water Management
Organisation of the course
• CT and AET together.
• Each week 1 class theory (Massink)
• Each week 1 class course assignment, including
GIS and Sobek in groups
• Theory in moodle.hz.nl
• Key course: …. Given in class
• Same material (powerpoints, ..) for Dutch and
English students. So sometimes also some dutch
words. Some documents Dutch and English.
• Assignments in moodle (obligatory)

How to manage (control) a water
system?
Which parts of the water system
are adjustable by people?
Why manage (control) a water
system?
3

• Preventing flooding (overstroming)
• Preventing drying out (droogte)
• Preventing salination (verzilting)
• Optimal groundwater level for agriculture
and nature
Managing the water system has a relation
with the use (function) of the land..
Why manage (control) a water
system?
3

• Evaporation; ground surface and vegetation
• Transpiration; type and density
• Surface runoff; paving, slope
• Discharge to sea; storage and pumps
• Recharge groundwater; ground surface
• Discharge to surface water; drainage, storage
Which parts of the water system
are adjustable by people?
3

• Groundwater
-drainage, trenches, ditches
• Surface water
-level (weirs) (stuwen)
-storage, dimensions (surface)
-culverts (duikers)
-pumping station (gemalen)
• Policy, legislation (wetgeving)

Water in the polder
• This course about water systems in the rural area
• Water system (groundwater and surface water)
optimized for agriculture and nature.
• Maximum production farmer
• Water quality is a bit ignored, more focus on
quantity
• Variation in time, precipitation and evaporation
.
4

Theory covered in this course
• Policy (Waternood, GGOR, HELP)
• Precipitation and evaporation (Neerslag)
• Groundwater flow and storage
(saturated and unsaturated zone)
• Drainage
• Weirs, open channel flow (stuwen)
• Pumping stations (gemalen)
• Culvert (duiker)
• Maintenance (beheer en onderhoud)

Exercise 1 Simple Peilgebied
• Peilgebied is an area with the same water levels
surface water (when it is not raining).
• Info on moodle, assignment on moodle
• Groups
• Report directly in moodle
