In thispaperwepresent anewalgorithmbasedonSmoothed 0 (SL0), called Block SL0 (BSL0), for Under-determined Systems of Linear Equations (USLE) in which the nonzero elements of the unknown vector occur in clusters. Contrary to the previous algorithms such as Block Orthogonal Matching Pursuit (BOMP) and mixed / 1 norm, our approach provides a fast algorithm, while providing the same (or better) acc...

The aim of this work was to test a modified version of the Universal Soil Loss Equation (USLE) for assessing the risks of erosion in N. Chalkidiki, Greece. USLE estimates the severity of erosion, thus assisting the decision process in selecting erosion control measures. Although USLE has several limitations, it was selected because it is the simplest approach while remaining robust, and it part...

One of the most common approaches to modelling soil erosion worldwide has been implementation original Universal Soil Loss Equation (USLE) and its revised version, RUSLE. However, despite widespread use, often there are discrepancies in methods used compute it values elicited for five individual factors that comprise this function. Such pitfalls subsequently skew final results obtained many stu...

DAS merupakan daerah sebagai tangkapan hujan yang rentan terhadap erosi dapat mengakibatkan permaslaahan pada sedimentasi Waduk. Besarnya terus meningkat mempengaruhi kinerja waduk. Tujuan penelitian ini adalah menadapatkan nilai laju menggunakan metode USLE (Universal Soil Loss Equation) dan DAS, serta membuat peta kriteria sebaran Waduk Randuguting dari tahun 2010 hingga 2019 dibantu dengan s...

O processo de uso e ocupação dos solos no Cerrado provocou grandes mudanças equilíbrio ambiental do bioma, se refletindo em forma diversos impactos ambientais. Dentro destes, está a perda por erosão. Apesar ainda apresentar porções vegetação nativa quando comparada ao restante estado, microrregião Vão Paranã Goiás possui características ímpares atributos físicos, o que torna palco degradações a...

The objective of this study was to evaluate and compare the erosion rates generated by two types hand tools for small-scale tillage on a hillslope, using experimental tests Universal Soil Loss Equation (USLE). evaluated were conventional hoe redesigned furrowing hoe. work conducted in 145 m2 plot with an average slope 45% Colombia. Three treatments evaluated: a) Zero no herbicide (control); b) ...
