Hydrologic description of river channels

General description and structure of the coast of channel and floodplain. Specify: steep, steep, sloping banks of the river there, whether they are covered with vegetation (a) or denuded. Mark, where more than just beaches and marshy floodplain. Explore the place where the river is particularly strong urge to shore erosion and deposited material. Determine the composition of rocks in the field of erosion, the causes of erosion and deposition of sediment (in each case). Description should be accompanied by sketches, photographs, samples of rocks. Overview of the flood plain, its terrain, available on her oxbow, streams, wetlands can best be up, moving along the ridge of high native shore. On the map mark the border the floodplain, where it rests on the high banks, apply Array bush paths, lakes, etc. As the floodplain is usually a good land and grasslands, and describe its vegetation cover make botanical herbarium, to take soil samples. Education Channel - Flatwater shoals, rapids. Indicate from which they are composed of rocks, measure the width and depth of the river in their places of education, length and width of structures themselves. Interview with local communities to establish the period to which the river bed formation are not available for shipping, timber rafting, how long (insert date) will be charged, and their area of ??ice cover is formed and how often, in what amounts to their ice jams. Determination of width and depth on the River. Depths are measured in those places where the river is determined by the width of the station. When sounding the observer moves along a taut rope dimensional, dropping into the water a universal rail at the marks on the rope. If measurements are made using "a lot, its pre-swung, threw down the movement of the boat, dropping lead-line, but a few delaying his hand to the moment when the load touches the bottom, the hand has experienced weakening lead-line and blow the lot on the river bottom. So like as we move the boat forward sounding line takes a vertical position, the resulting surplus was quickly purchased. A boat, which made measurements, is moved along a rope from shore to shore. To be more exact calculations follow recommended Gaugeable depth at the top, top and bottom gauges. Determination of soil DNA is conducted simultaneously with the sounding of depths. The first samples are taken bottom soil in the deepest place of the channel (on the fairway), and as often as possible when driving along the river. If the ground floor flows differs from the soil to the river, then the samples should be taken and with the influx.
