S/N  Morphometric Parameters  Derivation Procedure  Reference 
1.  Stream order (u)  Hierarchical order  Strahler, 1964 
2.  Stream length (Lu)  Length of the stream  Horton, 1945 
3.  Basin length (Lu)  This is the straight line from the mouth of the basin to the farthest point on the basin perimeter  Schumn, 1963 
4.  Main stream length (km)  This is the length of the principal drainage  Schumn, 1963 
5.  Main stream length (km)  Total stream lengths in the basin divided by total number of streams  Schumn, 1963 
6.  Total stream length (km)  This is the total length of all the tributaries and the principal drainage  Schumn, 1963 
7.  Basin perimeter (p)  This is the outer boundary of the drainage basin that encloses its area  Schumn, 1956 
8.  Bifurcation ration (R_{b})  ${\text{R}}_{\text{b}}=\text{Nu}/\text{Nu}+\text{1}$ , where u = total no of streams of order “u”, Nu + 1 = No of segment of the next higher order  Schumn, 1963 
AREA PROPERTIES  
1.  Basin Area (A)  Area = map scale counted squares  Gregory and Walling, 1973 
2.  Drainage Density (Dd)  EL/A where L = total length of all streams; A = Basin Area  Horton, 1945 
3.  Stream frequency (Fs)  N/A where N = Total no of streams; A = Area of the basin  Horton, 1945 
4.  Form factor  A/(Lb)^{2} where A = Basin Area, Lb = Basin length  Horton, 1932 
5.  Circulatory Ration (Rc)  AπA/P^{2} where A = Basin Area, π = 3.14, Lb = Basin length  Horton, 1932 
6.  Elongation Ration (Re)  $\text{2}\sqrt{\left(\text{A}/\text{\pi}\right)/\text{Lb}}$ where A = Basin Area, Lb = Basin length and π = 3.14  Schumn, 1959 
RELIEF PROPERTIES 

 
1.  Basin Relief (H)  Vertical distance between the lowest and highest points in the basin (max^{1} Hmin. H)  Schumn, 1956 
2.  Relief Ration (Rh)  H/Lb where H = basin relief, Lb = Basin length  Schumn, 1956 
3.  Max Relief (maxH)  The highest point value of elevation in a drainage basin  Schumn, 1956 
4.  Min Relief (minH)  This is the lowest elevation in a drainage basin.  Schumn, 1956
