The soil erosion bridge: a device for micro-profiling soil surfaces
The soil erosion bridge is a simple, robust, cheap, lightweight device comprising a bar which, when mounted on two stakes, provides a stable datum for micro-profiling the soil surface beneath. Its main advantage over similar devices is the unique
This software is designed to quantify the roughness of rock surfaces from profiles recorded using either a micro-roughness meter or a simple profile gauge. The roughness index used is the standard deviation of the differences between adjacent height
