Year 9 Water study trip

Water Study Trip

The Water Study Trip took place on Wednesday 21 February.  Here is the follow up homework task.  This is for assessment: the final grade for the Environment Unit will be based on your work in the unit overall (75%) and with a 25% weighting on this final task.

Homework: Write a description of one of the places we visited on the water study trip and explain what you learned about this place regarding the supply or the use of water.  Include a coloured pencil sketch of this place, with a clear title and labels. 

9A had a full lesson to work on this task  (22 February period 5) so just need to finish it off.  They have other homework instructions to prepare their thoughts on the next unit, International Development.

You may find some of the photographs on this page helpful when making your sketch. In case you have lost it for any reason, the original handout can be opened from a Word document here: Water study handout

This is the water channel (acequia) which brings the water into the mill pool at the top level of the mill


All the various functions of the mill – such as grinding the grain into flour and sifting the flour – are powered by water.  This is known as hydraulic power


We had our picnic lunch next to the nearby Roman remains of a much older mill, below the village of Sella.  This site is two thousand years old.

3. Photographs of the 17th century dam at Relleu

The bus did not take us to the 17th century dam and reservoir on the river Amadorio at Relleu because the driver thought the two kilometre stretch of road to it was too narrow, so we had to cancel this part of our trip.  We would have seen the oldest high dam of this type in Europe, built by Spanish military engineers.  (See explanation below, from the interpretation panels at the site of the dam.)

Relleu dam

This cross section of the Relleu dam shows why it was built at this point in the river: in the 17th century the technology only allowed for a narrow high dam.

The purpose of the reservoir was to provide water for crop irrigation and public use in La Vila Joiosa during times of drought, as the water cycle of the region has alternating periods of heavy seasonal  rainfall punctuated by times of drought that may last several years.


4. The modern Amadorio dam and reservoir at Orxeta


We finished the day passing the Amadorio reservoir where the level could be seen as less than half full after all the recent rains.  The old road bridge could be seen standing partly clear of the water: this was the old road between Orxeta and La Vila Joiosa before the dam was built in 1947.


About Gareth Thomas

A fairly mixed career starting as an aircraft technician and later Franciscan friar eventually led into secondary school teaching. I settled in Spain where I teach Geography part-time and spend the rest of my time looking after the needs of four donkeys in a remote location in the mountains in the Costa Blanca. I have three blogs: a geography blog and a donkey blog begun in 2015, plus an old donkey blog which ran from 2010 to 2015.
