2.2 Rivers (hydro cycle (infiltration - water soaks into soil, percolation…

- - - - saltation
        pebbles bounced
        along river bed
        
        suspension
        fine light materials is carried
        
        solution
        transport of dissolved materials
- - - - OXBOW LAKE
        
        horseshoe becomes tighter(erosion)
        
        next flood,
        river cut thr for a faster course
        
        river continues in new bed,
        meander is abandoned
        
        deposition fills in, cut off
    - - LEVEE
        
        natural embarkments
        
        flood:deposition bc drop on velocity
        
        deposition is encouraged
        
        large sediments - close to channel
        as river doesn't have 🌟
        
        small sediments - carry further away → deposits
        
        2 . more floods = more layers of sediments
        ➫➫ leaving higher ridges next to river
        
        Levees increase height of river’s channel,
        → bankfull discharge is increased
        → becomes harder for river to flood
- - - - ubrbanisation
        impermeable concreate
        water can't infiltrate
        get into river faster
        more overflow
        trees/plant removed
        less interception
        get into river faster
      - deforestation
        reduces transpiration/ interception
        soil become saturated faster
        increases surface runoff
      - steep side channel
        steep slope
        reaches river fastly
        fast surface runoff
