Assessment of rainfall interception, soil moisture dynamics and seasonal headwaters in a micro-catchment of Western ghats

The aim of this study is to assess the canopy rainfall interception, surface detention storage, and soil moisture fluctuation in a micro-catchment coffee plantation. Field measurements were carried out using 15 funnel-type ordinary rain gauges an experimental area 30 m × measure passing through upper lower estimate interception throughfall. Rain placed at different locations account for variability net falling over catchment. Throughfall compared with Gross taken open space near plot. overall ratio average ground precipitation gross measured season was 0.82. Analysis intensities showed that lower-intensity contributes higher fraction loss. Site-specific field-based equations have been developed convert into throughfall agrarian basins plantations. Soil depletion data revealed layer responds atmospheric demand quickly, deeper layers. Thick layers require longer duration reach field capacities contribute significant amounts flow seasonal/low-order streams. discharge after two months continuous soils plantation fields saturation during monsoon release water maintain non-perennial streams ends.
