variability of measured runoff and soil loss from field plots
introduction: field plots are widely used in studies related to the measurements of soil loss and modeling of erosion processes. research efforts are needed to investigate factors affecting the data quality of plots. spatial scale or size of plots is one of these factors which directly affects measuring runoff and soil loss by means of field plots. the effect of plot size on measured runoff or ...
متن کاملInvestigating the Effect of Surface Gravel Cover on Runoff and Soil Erosion with Simulating Runoff
Surface gravel cover is an important factor for contoroling of soil erosion in dry area specially in area that plant can not grow because of excessive dryness and salinity. The objective of this study was investigation effect of different surface gravel cover on runoff and sediment yeild. For this porpose, 36 field plots with 20 meter length and 0.5 meter width at 3 percent slope were construct...
متن کاملEffects of Soil Surface Rock Fragments on Runoff Variables of Field Plots under Rainfall Simulation
Soil surface rock fragment is considered as an important factor on runoff and soil erosion. However, few studies have been focused on quantitative evaluation of the effect of soil surface rock fragments on runoff components as an integral part of soil erosion process especially in natural conditions. The present study has been conducted to evaluate the effect of soil surface rock fragments ...
متن کاملSoil erosion and agricultural sustainability.
Data drawn from a global compilation of studies quantitatively confirm the long-articulated contention that erosion rates from conventionally plowed agricultural fields average 1-2 orders of magnitude greater than rates of soil production, erosion under native vegetation, and long-term geological erosion. The general equivalence of the latter indicates that, considered globally, hillslope soil ...
متن کاملQuantitative assessment of agricultural runoff and soil erosion using mathematical modeling: applications in the Mediterranean region.
Three mathematical models, the runoff curve number equation, the universal soil loss equation, and the mass response functions, were evaluated for predicting nonpoint source nutrient loading from agricultural watersheds of the Mediterranean region. These methodologies were applied to a catchment, the gulf of Gera Basin, that is a typical terrestrial ecosystem of the islands of the Aegean archip...
