Introduction
In this investigation, I will be investigating the changes along the long profile of a river. In order to do this, I will be collecting data and making observations at three different points along the river; the upper course, the middle course, and the lower course.
The river which I will be conducting my observations would be on Bartley Water. Bartley Water is a river going through the New Forest which is located in the south of the UK, Hampshire. The source of the river begins from Bartley, 109m above sea level, and joins to its end at Eling, flowing into Southampton Water. The river has a length of 27km and a catchment area of 40sqkm. It is a tributary of the River Test. The river bed contains of a mixture of sand, silt and clay which can change as the river behaves due to erosion, transportation and deposition.
The sites which I will be investigating on are:
• Site one is at Buskett’s Lawn, grid reference: 309109
• Site two is at Woodlands, grid reference: 325006
• Site three is at Eling, grid reference: 362124
The surroundings of these areas differ at each site. Site one is mostly rural areas whereas, when it moves onto the last site, it becomes an urban area. These will affect on the course and direction of the river and its characteristics.
The long profile of a river describes how the characteristics of the river vary from the upper course to the lower course. A quicker and easier way to present this idea is through a Bradshaw Model (see the diagram on
