What is morphometric analysis of watershed?
What is morphometric analysis of watershed?
Morphometric analysis of watershed is the best method to identify the relationship of various aspects in the area. It is a comparative evaluation of different watersheds in various geomorphological and topographical conditions [2].
How do you do morphometric analysis?
The morphometric analysis is performed through measurement of linear, aerial, relief, gradient of channel network and contributing ground slope of the basin (Nautiyal 1994; Nag and Chakraborty 2003; Magesh et al. 2012).
What is morphometric analysis in geomorphology?
Morphometric analysis is a quantitative measurement and mathematical analysis of landforms. It plays a significant role in understanding the geohydrological characteristics of a drainage basin in relation to the terrain feature and its flow patterns.
What is the use of morphometric analysis?
Morphometric analysis of a drainage basin expresses fully the state of dynamic balance that has been attained due to dealings between matter and energy. It finds out geomorphologic and structural control of flow and runoff and is helpful in predicting floods, their extent and intensity.
What is watershed shape?
The shape of a watershed influences the shape of its characteristic hydrograph. For example, a long shape watershed generates, for the same rainfall, a lower outlet flow, as the concentration time is higher. A watershed having a fan-shape presents a lower concentration time, and it generates higher flow.
What is meant by morphometric analysis?
External Websites. Morphometric analysis, quantitative description and analysis of landforms as practiced in geomorphology that may be applied to a particular kind of landform or to drainage basins and large regions generally.
What is morphometric measurement?
Morphometrics (from Greek μορϕή morphe, “shape, form”, and -μετρία metria, “measurement”) or morphometry refers to the quantitative analysis of form, a concept that encompasses size and shape. A major objective of morphometrics is to statistically test hypotheses about the factors that affect shape.
How is relief ratio calculated?
The relief ratio is a number calculated to describe the grade of a river or stream. The calculation is just the difference in elevation between the river’s source and the river’s confluence or mouth divided by the total length of the river or stream. This gives the average drop in elevation per unit length of river.
What is an example of watershed?
A watershed describes an area of land that contains a common set of streams and rivers that all drain into a single larger body of water, such as a larger river, a lake or an ocean. For example, the Mississippi River watershed is an enormous watershed.
What are the basic watershed classifications?
Three types of watershed are distinguished according to size: Small size: < 250 km….15.2.2 Small Watersheds.
| Size (ha) | Classification |
|---|---|
| 10,000-50,000 | Sub-watershed |
| 1,000-10,000 | Mili-watershed |
| 100-1,000 | Micro-watershed |
| 10-100 | Mini-watershed |
What is the morphometric analysis of the viswamitre watershed?
The morphometric analysis of Viswamitre watershed was car- 1. Basic param- e- ters include watershed area, perimeter, stream length, stream order and basin length. i. Perimeter (P) and Area (A)
How is morphometric analysis of watershed using GIS and Rs?
Morphometry is the measurement and mathematical analysis of the configuration of earths surfaces, shape and dimension of its landforms [1]. As per this we thing and go ahead and we found that for morphometric analysis all they (research papers) use techniques GIS approach and as well as Remote sensing integrated with GIS techniques.
How are morphometric parameters used for watershed prioritization?
The Morphometric parameters like stream length, bifurcation ratio, drainage density, stream frequency, texture ratio, form factor, circularity ratio and compactness coefficient and elongation ratio are considered for prioritization of all the mini-watersheds in the study area.
How are morphometric parameters used in land use analysis?
The morphometric parameters were categorized into three categories namely, basic parameters, derived parameters and shape parameters. The basic parameters include area, perime- ter, basin length, stream order, stream length, maximum and minimum heights and slope.
