What is morphometric analysis GIS?
Morphometry is the measurement and mathematical analysis of the configuration of the earth’s surface, shape and dimension of its landforms (Clarke 1996; Agarwal 1998; Obi Reddy et al. 2002).
What is drainage morphometry?
Drainage morphometry is defined as a measurement of linear, areal and relief characteristics of any drainage basin (Clarke 1966). Drainage morphometry was first initiated by Horton (1932).
How is drainage density measured?
Drainage Density is the total length of all the streams and Rivers in a Drainage basin divided by the total area of the drainage basin.
What is morphometric parameter?
It can be defined as an indicator of landform structure and hydrologic processes, erosional and physical properties of soil (Horton 1932;1945;Strahler 1964;Smith 1950). Morphometric parameters determine the lithological and structural control on drainage and characteristics of fluvial landscapes (Pati et al.
What is morphometric analysis in pathology?
Morphometric methods allow estimation of the limits of possible performance in histopathology, estimation of human performance in the diagnostic process and estimation of the influence of interfering human factors. Diagnostic decisions as well as decisions linked with therapy are basically probabilistic.
What is drainage density?
Drainage density is considered to be an important index; it is a measure of the texture of the network, and indicates the balance between the erosive power of overland flow and the resistance of surface soils and rocks.
How is drainage length calculated?
The Drainage Density is defined as the total length of all the streams and rivers in a drainage basin divided by the total area of the drainage basin and is represented as Dd = Lsb/Ac or Drainage Density = Length of all Streams of the Catchment/Catchment Area.
What is morphometric analysis of river?
Morphometric analysis of a river basin is essential to identify and assess seasonal changes in drainage basin characteristics, understand the groundwater potential, and address issues related to management of soil erosion due to flash floods during the high flows.
What is the formula of drainage density?
A mathematical model for this system, which was developed by C. E. Jacob, can be expressed in the equation T= WD~2/8h0t in which T is transmissibility, W is recharge, D is drainage density, and h0 is the height of the water table at the water table divide.
How drainage density is calculated?
The Drainage Density is defined as the total length of all the streams and rivers in a drainage basin divided by the total area of the drainage basin and is represented as Dd = Lsb/A or Drainage Density = Length of all Streams of the Catchment/Catchment Area.
How is drywell size calculated?
Divide the runoff volume by the 40% void space to find the volume of the dry well. If using a material that has a different void space, substitute that value for the 0.40 in the equation below. The total volume of the dry well will be used to determine the dimensions of the dry well box.
What is drainage length?
A measure of the length of stream channel per unit area of drainage basin. Unit of measure. km-ยน Spatial scale.
