Noticed a handful of typos in here just as it was being merged.

Suggested change

To produce total water level forecasts, OWP is adapting two coastal models to work with NextGen: the [Semi-implicit Cross-scale Hydroscience Integrated System Model (SCHISM)](https://schism-dev.github.io/schism/master/index.html) and [D-Flow Flexible Mesh (FM)](https://www.deltares.nl/en/software-and-data/products/delft3d-fm-suite/modules/d-flow-flexible-mesh). The initial development stages for the coastal model BMIs have been completed and their respective GitHub repositories are stored in the following pathways: SCHISM - https://github.com/LynkerIntel/SCHISM_BMI ; DFlowFM - https://github.com/LynkerIntel/DFlowFM_BMI . Once the NextGen framework evaluation is complete with the SCHISM Total Water Level (TWL) capability, the SCHISM BMI repository will be merged with the SCHISM master repository (https://github.com/schism-dev/schism) in the near future. For the DFlowFM model, it's BMI development is an entire seperate branch of the BMI code that is incompatible with the Deltares DFlowFM master branch and that will remain the case until the DFlowFM EC-module is redeveloped entirely for BMI compatibility. For now, the NOAA DFlowFM BMI development is a frozen DFlowFM version for research and development initiatives under the NextGen project in the future with the TWL capability.
