WEPS:  Management and CMZ Management Templates

WEPS is expected to reflect effects of various management practices and crop rotations on wind erosion.  The wide diversity of practices and rotations that are applied to crop land by land managers makes this a difficult task. 

WEPS must adequately simulate typical cultural practices to accurately assess their effects upon wind erosion management. The MANAGEMENT sub-model is assigned the task of handling the cultural practices that affect the soil/surface "state" within WEPS.

All cultural practices are by definition "human initiated". These human-controlled processes that affect the soil and field surface "state" are initiated by typical management practices such as tillage operations, planting, harvesting, irrigation, etc.

Therefore, the purpose of the MANAGEMENT sub-model is to model what are considered the major human-controllable actions that can affect the "system state" within WEPS, in particular the system state variables that define the temporal soil and surface conditions.

WEPS Crop Management Zone (CMZ) Templates:

Management Templates are updated periodically by NRCS State CMZ Leads and NRCS database stewards.  Each zip file contains common crop rotation / management systems for geographic areas (CMZs).  These multiple and single crop interval templates can be selected and customized with the WEPS management editor then used for WEPS Wind Erosion simulations.
