Setup PIHM for North Temperate Lakes
Plans for how to integrate lakes with PIHM, progressively more complex:
- Constant lake level. Streams flow in, flow out.
- Time variable boundary conditions (weakly coupled with lake model). Prescribe levels in the lake from data or GLM.
- Sequential coupling. Run PIHM, pass fluxes into GLM, pass the level back to PIHM.
Other properties for initial runs:
- 30 year simulation period (1979-2009)
- Use 40 m deep land surface. (Aquifer consists of 40 to 60 m of unconsolidated Pleistocene glacial deposits, mostly glacial outwash sands and gravel. Horizontal hydraulic conductivities are estimated to be ~10 m/day Pint et al 2003).
- Start with uniform soils.
- Use single atmospheric data set for entire domain. Two options, hydroterre forcing data or NTL data.
- Define dirichlet boundary condition (fixed as constant head) for all lakes in the catchment. Start with median lake levels. Can then implement time variable from GLM.
- No lake ice for now.
- Inlet boundary condition for riv file?
