Introduction

Topographic region from which a stream receives runoff, through flow, and groundwater flow is called drainage basin. Watershed divides and makes a suitable difference between each other by topographic barrier. The number and size of drainage basin varies with the location where it is found and with the scale examination. its scientist always considered the drainage basin as a open system which includes precipitation, snow melt, and sediment. There are factors which influence the input, output, and transport and stream flow of the water in the drainage basin, all these also influence the nature of the pattern of the steam channel which is in the drainage basin. These factors include topography, soil type, bedrock type, climate, and vegetation cover

Types of drainage patterns: Drainage Basin:

There are many types of drainage patterns which makes a drainage basin which mainly depends upon the topography of the basin upon the other factors which influence it. The concept of the drainage system can be used in different scales which include all the running which has the surface water whether it is a tiny creek or a large river. So we could say that one drainage basin can be part of another. For example, the Ohio River has a drainage basin including all of the surface area that it collects water from. However, since the Ohio empties into the Mississippi River, it is also part of the larger Mississippi River basin. The Mississippi River is North America's largest river and its drainage basin covers about three million square kilometers.

Trellised Drainage:

Trellised drainage patterns to develop where there is strong structural control upon streams because of geology. In such situations, channels align themselves parallel to structures in the bedrock with minor tributaries coming in at right angles. Areas with tectonic faults or bedrock joints can cause streams to take on a grid-like or rectangular pattern. Parallel drainage patterns are often found in areas with steep relief or where flow is over non-cohesive materials. Dendritic patterns are typical of adjusted systems on erodable sediments and uniformly dipping bedrock. Deranged drainage patterns are found in areas recently disturbed by events like glacial activity or volcanic deposition.
