Then if it rained one inch, all of that rain would fall on the plastic, run downslope into gulleys and small creeks and then drain into main stream. These tributaries enter the main river at approximately 90 degree angle, causing a trellis-like appearance of the drainage system. Most of this water moves through the plant and escapes into the atmosphere through the leaves. Parallel Drainage Pattern : Parallel drainage pattern comprises numerous rivers which are parallel to each other and follow the regional slope. They are governed by the topography of the land, whether a particular region is dominated by hard or soft rocks, and the gradient of the land.

10 Main Types of Drainage Patterns

The melting of the glaciers left land with many irregularities of elevation and a great deal of water to collect in the low points, explaining the large number of lakes which are found in. The tributaries join their master streams al­most at right angles and thus a rectangular drainage pattern is formed fig. You're standing, and everyone is standing, in a watershed. There are mainly 10 Pattern: Trellised Drainage Pattern, Dendritic Drainage Pattern, Rectangular Drainage Pattern, Radial Drainage Pattern, Centripetal Drainage Pattern, Annular Drainage Pattern, Barbed Drainage Pattern, Pinnate Drainage Pattern, Herringbone Drainage Pattern, Parallel Drainage Pattern. Cards Term Dendritic Drainage Definition most common and looks similar to a tree. During wetter portions of the year, these streams feed ephemeral lakes, which evaporate away during dry periods.

Most tributaries will join a larger stream at an acute angle. They are common in basins like in the United States Southwest region, where streams flow downward to a central point. Chapter 7, Origins of Stream Valleys and Drainage Patterns. This pattern is more frequently devel­oped on uniformly sloping and dipping rock beds such as cuestas or newly emerged coastal plains. It develops in regions underlain by homogeneous material.

Mainstream smoke is a combination of inhaled and exhaled smoke after taking a puff on a lit cigarette. Angles are both more and less than 90 degrees. Water gaps frequently become important corridors for the movement of people. Soils absorbing less water results in more runoff overland into streams. See: Sustainable urban drainage systems and Sewage. The depression formed at the top of Raigarh Dome in the Lower Chambal Basin has given birth to centripetal drainage pattern.

During the last , the was scraped off, leaving mostly bare rock. On the other hand, soils can vary widely in their ability to act as a hydrologic sponge. The result is a stream system in which streams consist mainly of straight line segments with right angle bends and tributaries join larger streams at right angles. It is an indicative of insequent streams flowing across horizontal and homogeneous strata or complex crystalline rocks offering uniform resistance to erosion. A watershed is an area of land that drains all the streams and rainfall to a common outlet such as the outflow of a reservoir, mouth of a bay, or any point along a stream channel. The differential erosion of hard and soft rock beds results in the truncation of the beds which produces ringed belted structure wherein relatively resistant beds project outward whereas the weaker soft beds form circular clefts. Drainage patterns are classified on the basis of their form and texture.

Stream Drainage Flashcards

The joints are usually less resistant to erosion than the bulk rock so erosion tends to preferentially open the joints and streams eventually develop along the joints. Angles are both more and less than 90 degrees. Straight · a stream channel is often straight near the headwaters where much of the erosion is in a downward direction 2. The dendritic pattern is associated with the areas of homogeneous lithologies, horizontal or very gently dipping strata, flat and rolling extensive topographic surface having extremely low reliefs. Bihar province presents a good example of radial drainage pattern wherein the Karamnasa and the Durgawati rivers and their source tributaries emerge from the south-western corner of the plateau and flow in the western, north-western, northern, and north-eastern directions whereas the tributaries of the Son River flow in the southern direc­tion.

The master conse­quent gradually but slowly lengthens its longitudinal course through headward erosion. Soils absorbing less water results in more runoff overland into streams. Vegetation slows runoff and allows water to seep into the ground. Well I'm not quite sure about four types but there are four main uses which are: Keeping freshness, enhancing color, altering flavor, altering texture. Trellised drainage patterns are generally formed in the regions of cuesta topography where hard beds become escarp­ments and soft beds are eroded to become valleys or lowlands.

All of these options cost, and the idea for the use of the land will have to come together with the availability of financing to determine which method or options will work best in any given application. This sequence of erosion, transport, and deposition applies to the other exogenic processes as well. These tributaries enter the main river at approximately 90 degree angle, causing a trellis-like appearance of the drainage system. Parallel drainage patterns form where there is a pronounced slope to the surface. There are ways to build in subterrainean drainage features, too. That is, the subsurface geology has a similar resistance to weathering so there is no apparent control over the direction the tributaries take.

. Perhaps the most famous divide is North America's Continental Divide, which separates drainage basins whose water eventually flows into the Atlantic and Pacific Oceans. Source: Centripetal The centripetal drainage pattern is just the opposite of the radial as streams flow toward a central depression. However, not all precipitation that falls in a watershed flows out, and a stream will often continue to flow where there is no direct runoff from recent precipitation. It all depends on the outflow point; all of the land that drains water to the outflow point is the watershed for that outflow location. Term Rectangular drainage patterns Definition found in regions that have undergone faulting.
