The aim of this study was to map the land condition within area Tumen River Basin (TRB), located on Sino–North Korean border, using trend analysis environmental factors. normalized difference vegetation index (NDVI) and surface temperature (LST) trends over past 30 years were analyzed identify areas that have undergone degradation, restoration, and/or a transition. Landsat NDVI LST obtained Goo...

2013年に発表されたSeahの「Universal Equation for Argon Gas Cluster Sputtering Yield」を紹介する．X線光電子分光法および二次イオン質量分析でおもに有機物試料のスパッタリングに用いられるガスクラスターイオンビーム（GCIB）によるスパッタ収率とスパッタイオンビームのエネルギーの関係を簡潔に示したSeahのスパッタ収率式（Seah’s universal equation）によって，金属から有機物まで様々な試料のスパッタ収率が表現できるばかりでなく，GCIBによるスパッタ過程を考察する上でも有用な知見が示されている．このSeahのスパッタ収率式以前の関連研究を踏まえた上で，Seahのスパッタ収率式が考案された過程とその応用の可能性について記述する．

Chure, also known as the foothills of Himalayas that extends from east to west Nepal, is an essential region due hotspot biological diversity and various natural resources, including recharge groundwater for Tarai country. However, Chure has a high rate soil erosion human activities processes, severe issue in region. This study looked at Gwang Khola watershed We used Revised Universal Soil Loss...

This paper describes multiple criteria models that can be used to assess land condition in general, and military training areas in particular. Three measures of land condition are used, namely: 1) erosion status, which is estimated based on the Revised Universal Soil Loss Equation (RUSLE), 2) percent vegetative cover, and 3) range condition. In addition, the paper also describes site-specific t...

The P-factor for support practice of the Universal Soil Loss Equation (USLE) accounts soil conservation measures and leads to a significant reduction in modelled loss. However, practical application, is most neglected factor overall due high effort determining or lack input data. This study provides new method automatic derivation main cultivation direction from seed rows tramlines on agricultu...

Phosphorus (P) Indices in the southern United States frequently produce different recommendations for similar conditions. We compared risk ratings from 12 southern states (Alabama, Arkansas, Florida, Georgia, Kentucky, Louisiana, Mississippi, North Carolina, Oklahoma, South Carolina, Tennessee, and Texas) using data collected from benchmark sites in the South (Arkansas, Georgia, Mississippi, No...

This paper will discuss the actual erosion estimation of Patria Nueva micro basin in tons/ha/year (E), located Tuxtla Gutiérrez Chiapas, Mexico. We used universal soil loss equation (USLE), considered one best theoretical tools for planning and preservation USA other countries. The rates were estimated 5, 20, 50, 100, 500 years return periods (Rp), with elevated results due to high degrees anth...

Ridge and furrow fields are land-use-related surface structures that widespread in Europe represent a geomorphological key signature of the Anthropocene. Previous research has identified various reasons for intentional unintentional formation these structures, such as use mouldboard plough, soil improvement drainage. We used GIS-based quantitative erosion modelling according to Universal Soil L...

The Three Gorge Project (TGP) of China necessitates the resettlement of over 1 million population (mostly farmers) to more rugged and isolated areas than their original settlements. Soil erosion is a serious environmental and production problem in this area. To decrease the risk on environmental impacts, there is an increasing demand for sound, and readily applicable techniques for soil conserv...
