A constellation of synonyms exist for the word “river”: what distinguishes these naturally flowing watercourses from a beck, bourn, brook, burn, creek, rill, rivulet, runnel, or tributary may come down to the size of the stream or may simply be a regional preference. Rivers flow across every continent and on all but the smallest islands, carving, eroding, and reshaping the Earth’s topography; c...

The accumulation of heavy metals in agricultural soils is a serious environmental problem. The Campania region in southern Italy has higher levels of cancer risk, presumably due to the accumulation of geogenic and anthropogenic soil pollutants, some of which have been incorporated into organic matter. The aim of this study was to introduce and test an innovative, field-applicable methodology to...

Black soil areas are strongly affected by rill erosion due to the geomorphic characteristics of flood plains and heavy rainfall. To study problem in black achieve ecological restoration, based on method artificially simulated rainfall, effects rainfall intensity slope flow sand production surface were studied, pattern after was monitored a 3D laser scanner analyze surface. The model constructed...

Pandemi Covid 19 yang berlangsung lebih dari setahun telah menimbulkan dampak begitu luar biasa bagi berbagai sektor, salah satunya adalah sektor Pariwisata. Adanya fenomena ini membuat sector pariwisata mengalami penurunan signifikan dan kondisi membutuhkan waktu lama untuk kembali bangkit. Oleh karena itu, dalam merespons perlu adanya pemanfaatan teknologi pariwisata. Virtual reality tour sat...

Latar Belakang: Perusahaan go public di Indonesia rata-rata memiliki laba yang tinggi namun tidak menjamin dengan kualitas nya. Perbedaan kepentingan antara manajemen investor mendorong untuk melakukan praktik income smoothing sehingga mampu menghasilkan fiktif. Penelitian ini menekankan pentingnya sistem good corporate governance dalam meminimalisir terjadinya smoothing.Tujuan: bertujuan mengu...

The assessment of the erodibility of soil materials is essential for analyzing and modeling rill, gully, streambed, streambank, spillway, and embankment erosion. A submerged jet−testing apparatus has been developed and used for characterizing soil erodibility in several applications as cited in the literature. The apparatus has been developed based on knowledge of the hydraulic characteristics ...

This study presents the comparison of experimental results with assumptions used in numerical models. The aim of the field experiments is to test the linear relationship between different hydraulic parameters and soil detachment. For example correlations between shear stress, unit length shear force, stream power, unit stream power and effective stream power and the detachment rate does not rev...
