Drainage analysis in watershed development –A practical planning tool Drainage analysis involves understanding how water flows through landscapes, identifying streams and rivers within a watershed. Different drainage patterns include dendritic, trellis, rectangular, and parallel formations. Key analysis parameters include watershed area, stream orders, the number and length of streams. Important calculations are the bifurcation ratio (comparing stream orders), drainage density (total stream length per watershed area), and stream frequency (number of streams per area). This data helps in understanding watershed characteristics and hydrological behavior for effective water resource management.
