A rivers flow is the volume of water that moves past point on the river in a given time. Volume of flow is also called discharge. As more water flows through a river, its speed increases. A flooding river can carry huge amounts of sand, soil, and other many
Water Velocity & Sediment Depth in Streams Introduction: Water covers over 70% of the world and is one of the most essential compounds in life. Water is continuously cycling to transport nutrients around the world. Rainfall will wash away sediment and carry it through streams, rivers, and other flowing bodies of water. Certain sections of flowing bodies of water can be classified as riffles, runs, and pools based on the velocity of the water. A riffle is a shallow, fast moving section of a stream and is usually followed by a run, where the water tends to be deeper and slower.
The water is on a downward gradient and is constantly supplied by the 1200mm of rainfall it gets each year. On either side of the river at this stage are steep slopes that are mainly used as grazing land for sheep. There are also a few reservoirs which help supply water to other places further south. Not many plants can grow around the river, but you do find some coniferous plants and occasionally coniferous plantations. There are lots of walking routes around the river Tees one of them being of the Pennine way the long distance walking route within the Pennines.
Pesticides can travel great distances through the environment even if that is not the intention. Whether the chemical is sprayed on crops or in gardens, the wind can blow the pesticide to other areas that may be pesticide sensitive. They can also flow into rivers or streams where they are carried to new locations or they can seep deep into the soil and affect the groundwater causing unexpected harm to those who drink the contaminated water. As part of a National Water Quality Surveillance Program both British Columbia and Ontario were found between 2003 and 2005 to have the largest number of pesticides found in aquatic ecosystems and sensitive surface waters. Samples were taken from approximately 140 sites and 15 watersheds of various sizes.
The first thing that caught my eye when I saw this letterpress was the orange leaves. This is because they are the brightest thing in the picture and also in front of everything else. So the picture is visually organized to make someone’s eyes start off by looking at the leaves and then it carries the viewer to the blue river which then leads the person up to the house with the two dogs outside. Rachael uses shading on the bank of the river to show that the ground has a slope. The Leaves Were Falling is a dynamic piece of artwork.
Hypothesis: As valley gradient increases, velocity of the river also increases. Testing this hypothesis required a method with specific equipment, and we decided to use systematic sampling in order to achieve a fair test. Finally, we created tables for data recording. Method: 1. Use clinometer to measure gradient of river valley.
Not only did they use the river for water and food, they also used the river for main transportation and trading goods. Although the Nile River flooded once a year which caused destructions, it provided them with a layer of silt that fertilized their soil that allowed them to farm all year round. The Egyptians welcomed these annual floods and showed their gratitude to the river god Osiris. They were connected with their religion especially through Osiris. The Nile river also supported in their early political unification between upper and lower Egypt.
Depending on its location the average yearly rainfal in rainforests is usually 68-98 inches (1750–2500 mm). All rainforests are endangered. This means they are disappearing. We must save them.

Trees grow up to 40m high, break through the low cloud layer and gain the sunlight. The leaves have tips that curve downwards so the rain drips off. The undergrowth will spring up wherever light reaches the forest floor and fallen leaves and plant matter rot swiftly to provide the nutrients that the rest of the plants require. The region is home to about 2.5 million insect species, tens of thousands of plants, and some 2,000 birds and mammals. One in five of all the birds in the world live in the rainforests of the Amazon.
