ArcAPEX Training – China – August 2016

August 1, 2016 - August 2, 2016

Title: Modeling Agricultural Watersheds using ArcAPEX

Please email us at for more information! Thank you!

Bio-physical processes occurring in the cropping systems of agricultural watersheds are a great challenge to replicate in a modeling framework. APEX was developed to evaluate various land management strategies considering sustainability, runoff, erosion, water
supply and quality, soil organic carbon and soil quality, plant competition, weather, pests and economics. This training course offers the fundamental principles of the APEX model for use in watershed management with hands-on exercises. The objective of the training is to introduce new users to the model, review necessary and optional inputs, and familiarize the user with the ArcAPEX and general procedures of model development, implementation and evaluation.
