EAA Storage Reservoirs Revised Draft PIR and EIS February 2006
4-9
• SEEP/W - A two dimensional finite elements computer program. This
program is generally used to evaluate relatively smaller areas than the
Modflow program. This program has been used to evaluate total seepage
from the reservoirs, seepage quantities to the seepage collection canal,
exit gradients, and effects of the buffer on the seepage flow.
• SFWMM - Stage-duration curves, hydrographs, water budget analysis,
savings clause, and water reservations.
• Natural Systems Model (NSM) - Used to characterize pre-drainage
conditions in the EAA Storage Reservoirs Project area.
• HEC-RAS - Alternative canal improvements and hydraulic profiles.
• SEEP/W, Modflow- Seepage collection requirements, effective use interior
cells, seepage reduction, seepage buffers and collection operations, flood
damage reduction, and savings clause.
• MIKE-SHE (will be used for the Final PIR) – Final hydraulic structure
designs.
• IWRPlan - Decision support software.
