Watershed 2022-01-21

Features

• Two parameters can be changed in ./source/draining/config.json, including (i) side length of search buffer (default 20km) and (ii) minimum ratio of an adjacent upstream reach to the side length (default 0.4)
• Provides a choice of data types for Flow Accumulation (acc_type), which are 32-bit unsigned integer ("u4", the default value to boost up the calculation, sufficient for 90m flow direction) and 64-bit unsigned integer ("u8", helpful in delineating extra-large watershed with 30m flow direction, such as Amazon River)

Bugfixes

• station.xlsx with extra blank rows causes watershed delineation to fail
• several gdal dependencies are missing from ./source
