The TCRP model can be used to create a runoff pattern, taking into account the effects of tillage-induced roughness. The TCRP model has as main aim to adjust

runoff patterns based on topography for tillage induced roughness. The resulting output of TCRP are runoff pattern raster maps, which can be further used as input

for hydrological modelling of surface runoff processes. The methodology to create the runoff pattern includes four steps. First, a topographically controlled runoff pattern is created using the standard single-flow, steepest descent algorithm. Next, a tillage-determined runoff pattern is created, i.e. a runoff pattern based on the assumption that water will always flow in the tillage direction. Then, decision rules are applied to determine for each cell whether the water will flow in tillage direction or in topographic direction. Finally, a flow direction map can be generated by combining the topographically determined runoff pattern with the tillage-controlled runoff pattern. This repository is an updated version of the original code, adjusted to run smoothly with the current version of PCRaster (v4.4.0)
