Hydrological and erosive response of a small catchment under olive cultivation in a vertic soil during a five-year period: Implications for sustainability

摘要: This study presented monitoring results during five hydrological years representative of the typical climate conditions in region, a commercial olive farm on vertic soil with management based limited tillage and growing natural weed vegetation along traffic lanes. A significant sediment delivery to streams equal 16.1 t ha−1 year−1 average was observed, whereas especially high values rainfall depth above annual rainfall, up 52 were recorded. Our observations within catchment indicate that rill gully erosion major processes which require specific control measures such as modification for reducing compaction tractor tramlines use buffers prevent erosion. The analysis variables suggests an adequate prediction runoff generation this kind should take into account complex response soils, causing large variability hydraulic properties associated changes moisture. To model loads, addition need accurate volume peak flow, dominance contribution have be considered.
