Equipment available
The Armfield hydrology system sets out to demonstrate, on a small scale, some of the physical processes found in hydrology. These processes fall into two related categories: the relationship between rainfall and run-off from catchment areas of varying permeability, and the abstraction of ground water by wells with and without surface recharge from rainfall.
Several practical exercises are available for this equipment.
- Exercise A - Rainfall-runoff relationships (storm hydrographs).
- Exercise B - Generation of overland flow.
- Exercise C - Initiation and characteristics of bedload motion.
- Exercise D - Effect of changing stream power on channel morphology.
- Exercise E - Effect of base level change.
- Exercise F - Scour in open channel flow.
- Exercise G - Water abstraction from a well in a confined aquifer.
- Exercise H - Water abstraction from a well in an unconfined aquifer.
- Exercise I - Water abstraction from a number of neighbouring wells.
- Exercise J - Rainfall on a circular island with a central well.
- Exercise K - Ground water flow between two canals with and without rainfall.
We have the potential to alter this system to meet your requirements if you require.
Using the equipment
The equipment can be booked for use, outside of prac times, by contacting one of the Civil Technical Officer by email – Leanne Farago or Candice Chan. Please allow an hour for training on this equipment.
Useful links
The Armfield multipurpose teaching flume is a scaled down version of a large flume. Various phenomena can be seen and measured which allows students to understand the fundamental concepts of energy and momentum where free surface flow is concerned.
Several practical exercises are available for this equipment:
- Exercise A - Characteristics of Flow over a Sharp Crested Overshot Weir
- Exercise B - Characteristics of Flow over a Broad Crested Weir
- Exercise C - Characteristics of Flow over a Crump Weir
- Exercise D - Discharge Beneath a Sluice Gate
- Exercise E - Force on a Sluice Gate
- Exercise F - Derivation of the Specific Energy Equation
- Exercise G - The Hydraulic Jump
- Exercise H - Characteristics of Flow Through a Venturi Flume
- Exercise I - Characteristics of Flow Through a Culvert
- Exercise J - Characteristics of Flow Around Flow Splitters
- Exercise K - Characteristics of Flow Over a Dam Spillway
- Exercise L - Characteristics of Flow Through a Siphon Spillway
- Exercise M - Characteristics of Flow Through an Air Regulated Siphon
- Exercise N - Characteristics of Flow Under a Radial Gate
- Exercise O - Characteristics of Flow Over False Floor Sections
- Exercise P - Characteristics of Flow Over a Gravel Bed
We have the potential to alter this system to meet your requirements if you require.
