I�@am master student, my topic is about rill erosion patterns, I need
to use microtopographic scanner for the surface roughness and also I
want to use photogrametry techniques, I need some help in:
1) What is the suitable laser microtopographic. Scanner and could you
introduce some companies?
2) What is the suitable accuracy for 1m**2 plot using simulated
rainfall?
3) Some reference about photogra. Tech. for soil roughness
