MOSES Management Subgroup

---

CHARGE:

The MOSES subgroup was formed to address issues related to management "operations" and the development and modification of "management descriptions" within the MOSES interface.

GOAL:

To develop the necessary structure, visual screens, and processes required to allow MOSES to provide the user with a uniform, easy to use, intuitive means of creating and modifying management descriptions for all ARS erosion models (WEPP, WEPS, RUSLE2, and RWEQ).

INTRODUCTION:

The MOSES Management Subgroup is charged with dealing with and resolving all issues related to physical actions that a land manager can control and schedule. These management actions or MOSES "operations" include, but are not limited to, operations such as: primary and secondary tillage, planting, harvesting, cultivation, burning, grazing, irrigation, application of herbicides, pesticides, and fertilizers, etc.

Each MOSES "operation" is defined as a list of physical "processes" representing the actual action(s) performed by the "operation". A list of MOSES "operations" or management actions applied to a given land unit, including dates and/or rules specifying when they occur, is called a "management description" (management/crop rotation scenario). Most users are expected to select pre-built "descriptions" and modify them as necessary to create the "management description" scenario for a particular simulation run. Thus, how easily a user interacts with MOSES to select and view individual operations and groups of operations (full or partial management description scenarios) is important.

OBJECTIVES:

1. MOSES management related fundamental physical processes.

• Define each fundamental physical process handled in MOSES.
• List and define each processes parameters/variables.

• Address issues such as "shared" parameters and model specific needs for each process.

2. MOSES management related operations.

• Describe how an "operation" is defined in MOSES.
• Provide guidelines that define a valid MOSES operation (rules, restrictions, etc.).
• Address issues such as multi-tool and multi-implement tillage operations, schedule-based operations (irrigation), and erosion model specific differences.
• Develop a list of core operations for MOSES testing.

3. MOSES management descriptions.

• Define what constitutes a valid MOSES management description.
• Describe how user will interact with MOSES to build/modify management descriptions.
• Define management description screen layout(s) and functionality.
• List actions/tools a user will need to construct/modify management descriptions.
• Address any model specific issues related to management descriptions.

• Develop some sample management descriptions for MOSES testing.

4. MOSES management operations (user interaction).

• Describe how user will interact with MOSES to build/modify management operations.
• Define management operation screen layout(s) and functionality.
• Example screens
• List actions/tools a user will need to construct/modify management operations.
• Address any model specific issues related to management operations.
