Task 2: Water management – Beixiaohe River [9 marks]

Observe the river and annotate on a separate worksheet version of the map provided (Fig. 2), notes about:

i. its form and structure;

ii. what functions it serves with respect to water management in this part of Beijing;

iii. what functions it serves within the local community.

Examples of possible answers and marking scheme for the annotated map [6m]

Award 1 mark for each clearly labelled annotation which refers to form and structure, up to a maximum of 2 marks.

i. Form: straight, steep banks, single channel (no tributaries or branches)
Structure: made of cement and stone, hard engineering, fixed/inflexible banks which do not allow river to change its course

Award 1 mark for each clearly located and labelled annotation which refers to the functions it serves with respect to water management, up to a maximum of 2 marks.

ii. form and structure of the river indicates that the main function of the river is to allow for quick discharge of water out of the area to prevent flooding in the Wanjing District.
The presence of the barrier in the channel may also serve to regulate water flow/ levels and/ or to trap sediments and trash in order to clean up the waterway.

Photograph looking along the straight, stone-banked Beixiaohe River channel with willow trees and a footpath on the left bank, a low bridge with buses in the distance and rough stone blocks on the right bank.

Award 1 mark for each clearly labelled annotation which refers to the functions it serves within a local community, up to a maximum of 2 marks.

iii. Extensive recreational functions – benches for relaxation, paths for walking /jogging on elevated embankment, occasionally you can see somebody angling with a fishing rod in the river.

Photograph of a man fishing with a rod from the concrete edge of the river bank, with a small green stool beside him, trees, a bridge and high-rise buildings in the background.

Write brief observations of the water quality of the river in Table 1 below. [3m]

Answers: award half mark for each correct observation per indicator [total 3 marks]

Table 1

Indicator		Observations
Clarity		Turbid
Water Flow	Velocity	The flow rate is slow, stagnant, sluggish
	Depth	About 1m
	Obstacles	Waterweeds, silt around the pier
Smell		No detectable smell
Aquatic organisms		Waterweeds, fish, frogs

NB: the above is based on the observed results on August 7th. It rained in the evening of August 6th. The observed results would differ under different time and weather.
