SZ Drainage Downstream Water Level Check

You can optionally check the downstream water level before calculating SZ drainage. This prevents drainage from being added to rivers during a flood, for example. It also prevents recirculation of SZ drainage water when using Flood Codes.

Testing has shown that the test on drainage to local depression can nega­tively impact runtime because the number of outer iterations in the PCG solver may increase. Thus, the downstream check has been separated into two Extra Parameters.
