For schools whose River Study measurements have been soaked by a downpour or are unreadable, a set of sample recordings is available using the link below:

Draw cross sections, to scale, of the upper and lower valley sites (such as on the river study record sheet). Use the chart information from activity 2 to draw a cross-section of where you measured the depths across the river. What is the average depth?
Calculate the water area. Using your depth readings make a downstream drawing. What is the average depth in the stream centre? Analyse your group's readings of the dog biscuits activity and explain why the times taken were different. Work out the velocity of the stream (distance divided by time in seconds) in metres per second. Calculate the volume of water in cubic metres per second (area x velocity). What are the other groups' findings? Make hypotheses for the variations and justify with statistical evidence.
If you did an invertebrate study, graph the frequency of types of life found, draw conclusions from findings at different sites. Sketch them and classify as herbivores, carnivores or detritivores and develop a food chain. Graph biotic index scores.
How can you help conserve the countryside? Write about litter, dams, bank breakdown, shouting, stone throwing, off path disturbance, single file walking, dogs, bikers, picking of flowers. How can your lifestyle can influence where you visit and what you see (the food or fashion products you buy, packaging, eating habits, exercise).
Dictionary definitions: create your own for: confluence, tributary, source, channel, mouth, spring, watershed, leat, point bar, meander, pool, riffle, scree, erode.
Abbreviations: NT at CMV is ESA (Environmentally Sensitive Area) AONB (Area of Outstanding Natural Beauty) SSSI (Site of Special Scientific Interest). Devise your own for a country code. Make a list of well know ones.
National Trust: describe its work in CMV (footpath repairs, pitching, scree cages, geo-jute, tree planting, drainage traps, litter collection, spraying bracken) Discuss problems: sheep, sheep scrapes, bracken, fires, terracing or soil creep.
Natural History: Library research of gorse, bracken, heather, lichens, bilberry, freshwater invertebrates.
Pools of Imagination: Create own stories describing silt ponds, river sounds, flowing movement, riverbank animals and plants, reaction of people to water. 'Mr Grumpy's Outing'. 'Webster's Walk'.
Reproduce a quality labelled diagram from the field sketch using an explanatory key from above definitions. Where did the stream come from and where is it going? Life cycle of river, draw and annotate. Water usage in homes now and in the past. Rivers used for transport, energy, recreation, industry. Pollution. Soil retention by grass. Differences on slopes, both in types of vegetation and in amount of crags and scree. Why? Human impacts on the valley. Honeypot site - list CMV services to attract tourists away from other valleys.
History of Geology. Valley formation. Bodbury Hillfort 500BC. From oak forest to hill farming. The Mill 1812. Factory 1824. Bottling 1881. Reservoir 1902. Scandinavian Chalet Pavilion 1920. Swimming Pool 1930 - 1960. Research the history of the valley in the 'Background' section of our website.
