Eleven geomorphic indices: Basin Length, Basin Area, Basin Perimeter, Basin relative Relief and Relief Ratio, Hypsometric Integral, Asymmetry Factor, Elongation Ratio, Stream Length, Stream Number and Bifurcation Ratio Index, are calculated from DEM data to determine the relative tectonic activity along the JFZ.
Important areal, linear and relief parameters were computed such as perimeter, basin area, basin length, drainage density (Dd), stream frequency (Fs), elongation ratios (Re), bifurcation ratio (Rb), circulatory ratio (Rc) etc.
Many a researcher defined basin length accordance with their own research.

L = the basin length, which is the straight line between the ends of the basin.
By study the relationship between morphometric measurements and the values of the annual rate of erosion (Table 4) by using the Pearson correlation coefficient, found a positive correlation (+0.97: 0.99), where the erosion is greater with increasing the basin length and basin area.

The Complex for measurement of characteristics of space oscillations of floating objects in the experimental (wave) basin which receiving ends are placed at various depth and at various distance along basin length.
In phase displacement size [gamma] between wave-recording gauges along length of the basin the actual wavelength is determined by a ratio [[lambda].sub.r] - 2[pi][L.sub.w]/[gamma] ([L.sub.w] is the distance between wave-recording gauges along basin length).
The results show baffle increase removal efficiency and best position is first third until half of settling basin length. In addition, best height is equal to 0.4 of water deep in settling basin.
The maximum basin length (L; Horton, 1945; Schumm, 1954) is the distance between the two most distant points in the basin and characterizes best the absolute size of the latter.
This parameter is strongly positive-y correlated with the maximum basin length (cf.
