HYDROLOGY CYCLE: Water Movement Basic Energy: Gravitation Energy: surface runoff, infiltration, percolation Solar Radiance Energy: capillary water, water in plant
HYDROLOGY CYCLE evapotranspiration interception precipitation Surface Runoff Interflow Infiltrasi Perkolasi 1 cm soil solum are formedfor15-200 years Interflow Groundwater surface Ground water flow
Water balance is part of water cycle and determine the hydrology existence Evapotranspiration Rain Water transported out with biomass crop Surface runoff surplus Soil surface Recharge with plant litter Infiltration Moisture zone Recharge Vegetation Consumption Recharge contain in soil biomass Total outflow Interflow zone Percolation surplus that recharge groundwater Ground water out flow Ground water Recharge soil moisture from shallow groundwater SCHEME OF WATER BALANCE IN THE PEDOSPHERE
Land as a system Atmosphere Hydrology Cycle Gas cycle(CO2, O2, H2) Biosphere Hydrosphere Transfer of material and energy Water and mineral cycle Organic matter cycle Pedosphere Lithosphere (topography) Lithosphere (mineral, rocks, geology) Anthroposphere Component in Hydrology System:
Discussion: • Interaction type/ interrelationship between components with compensatory or anti-compensatory • Natural components: topography, soil type, season/climate • Human-involved components: land use, slope, slope length The Biophysical components determine: Evapotranspiration Infiltration, percolation, runoff Water volume in soil, river discharge
Vegetation role is very important whyyyy ? Vegetation changes soil physical and chemical properties in relation with water Evaluation1
Processes in hydrological cycle: • Precipitation • Evaporation, transpiration, evapotranspiration • Interception • Throughfall, stemflow • Runoff, Infiltration, percolation, groundwater • Soil moisture, subsurface/interflow The key for Watershed Planning and Management
