WebMar 22, 2024 · Drainage basins characterised by impermeable rock and soils tend to have higher drainage density due to the lack of infiltration and percolation. This means that water enters a channel quickly, leading to an increase in discharge. Web- River Systems: Drainage basins collect precipitation and channels towards the coast. Availability depends on land use, basin size and shape and precipitation type. Flow increases downstream but climate creates variation in discharge and water loss. Climate can also produce river regimes where water is supplied through glacial and snow melt.
