Task Question: Investigate how and why channel characteristics vary across your chosen river with distance downstream.

You will complete a fieldwork investigation and final report.

Word limit: Make sure that your final report is within 10% of the 2000-word limit.

The purpose of the investigation is to study how the channel characteristics of the Chrysochou

River change downstream and to examine the factors which affect these variations.

Characteristics:

1Discharge

2Occupied channel width

3Channel depth

4Average velocity

5Channel bed roughness

6Slope angle (gradient)

(no possible measurement of load particle size)

Theory : Textbook page 66 and 67

Hypotheses for how the channel characteristics of the Chrysochou River change downstream.

We expected the following characteristics to:

increase downstream

1- Discharge

2- Occupied channel width

3- Channel depth

4- Average velocity

decrease downstream

5- Channel bed roughness

6- Slope angle (gradient)

Hypotheses for why the channel characteristics of the Chrysochou River change downstream

There is a correlation between discharge and variations of the channel characteristics downstream.

Therefore we expect the following to occur from site 1 to site 3: a- positive correlation between discharge and river width and depth b- positive correlation between discharge and velocity

C- negative correlation between discharge and gradient d- negative correlation between discharge and bed roughness
