Groundwater Functionality - Main Summary Ticket

[dvalters]

Several new components have been added to the CAESAR-Lisflood code upstream (the Windows version). AB has added these componets to the CAESAR_GW batch of code. The main additions are the model options of swappig out TOPMODEL for SLiM to incorporate groundwaer more realistically. There is a basic groundwater option and a separate option that allows the user to run with the SLiM model that includes water partitioning (overwriting the standard recharge process)

Groundwater inputs

• Initial groundwater
• Groundwater boundary file
• Hydraulic conductivity (m/d) file
• Specific yield (-) file
• Recharge rate (% rainfall 0-1)

Water Partitioning

• Start date
• HOST file(?)
• Landuse file
• Potential Evaporation location file
• Potential Evaporation table file
• Initial soil moisture deficit file

There is a test case for both GW and SLiM in the CAESAR_GW folder

The key functions to look at are:

• wpgw_water_input()
• water_partitioning(rain_data_time_step)
• Groundwater_Flow(1440)

Key data structures:

• dailyBF[][]
• wp_added_water_daily[][]
