River Cross Section

Set cross section x axis range.

River cross section. The first stage is to measure the width and depth of the river. Producing a cross section of a river channel is a basic river fieldwork skill. Change river cross section title.

The cross profile of a river changes as it moves from the upper to lower course as a result of changes in the river s energy and the processes that the river carries out. A as the river flows downhill there is an increase in vertical erosion. River cross profiles show you a cross section taken sideways of a river s channel and or valley at certain points in the river s course.

A cross profile shows a cross section of a river s channel and valley at a certain point along the river s course. When selected a property sheet like that shown below will be displayed. The rivers cross option allows you to extract river cross sections from a model.

The cross profile of a river sometimes called a cross section shows how the river looks at certain points like the upper stage or middle stage etc. The soundings are taken b t and after dredging work is done. Select straight lines smooth lines.

How and why does a channel cross profile change downstream. A channel cross profile only includes the river whereas a valley cross profile includes the channel the valley floor and the sides of the valley. It is also used when it is required to determine the quality of material removed by dredging.

It is used when sounding are to be taken along the cross section of a canal or narrow river. Enter number of depth measurements min 5 max 25 select cross section type. Whether you need to find the discharge or examine the profile of a feature such as a meander or riffle it will be necessary to produce a cross section of the river.
