Intense soil erosion in the northern part of Gerecse Hills, Hungary, is causing significant damage to vineyards area. Three Neszmély Wine Region were investigated quantify amount eroded soils. The method was based on monitoring for one-year between July 2019 and June 2020. Every season, a set photographs taken from an unmanned aerial vehicle. images processed photogrammetric workflow produce hi...
Penelitian ini dilakukan pada bulan Juli 2017 di sekitar Sub-DAS Batang Limun Kabupaten Sarolangun Provinsi Jambi. bertujuan untuk menghitung laju erosi dan menentukan tingkat bahaya yang terjadi disekitar Sub DAS Limun. Metode digunakan dalam penelitian adalah USLE (Universal Soil Loss Equation) dengan pendekatan Geographic Information System (GIS). Berdasarkan hasil menunjukkan bahwa dari sel...
Prediction of Soil Erodibility by Diffuse Reflectance Spectroscopy in a Neotropical Dry Forest Biome
The USLE and the RUSLE are two common erosion prediction models that used worldwide, soil erodibility (K-factor) is one parameter to calculate them. objectives of this study were investigate variability soil-erodibility factors under different soil-texture classes evaluate efficiency diffuse reflectance spectroscopy (DRS) in near-infrared range at predicting K-factors using a partial least squa...
The aim of this study was to propose a methodological approach determine the best land use based on USLE model parameters, using watershed as planning unit. parameters were spatialized software ArcGis 10.5, for case Cachoeira Cinco Veados watershed, RS-Brazil, and erosive values categorized according methodology Ribeiro (2006). We reclassified areas in “suitable” “not suitable” tested use, two ...
فرسایش خاک یکی از مهمترین مسائل محیطی در دنیا بوده که عامل مهم بروز خسارات بزرگ اقتصادی و تهدید جدی برای توسعه پایدار محسوب میشود. در مقیاس حوضهای، عوامل متعددی در زمینهسازی و تشدید فرسایش دخیل هستند. در فرسایش خاک توسط روانابها عوامل داخل حوضهای مانند خاک، توپوگرافی، تراکم زهکشی والگوی کاربری نقش مهمی ایفا میکنند. در مناطق نیمهخشک وضعیت فرسایش خاک در محیطهای کوهستانی و در سطح زمینهای...
Soil erosion is a serious worldwide environmental problem that stems from a combination of several factors such as agricultural intensification, deforestation, increasing population, and rainstorms. This phenomenon produces a soil fertility decline, removes soil rich in nutrients and increases natural level of sedimentation in the rivers and reservoirs reducing their storage capacity as well as...
As one of the key tools for regulating human-ecosystem relations, environmental conservation policies can promote ecological rehabilitation across a variety of spatiotemporal scales. However, quantifying the ecological effects of such policies at the regional level is difficult. A case study was conducted at the regional level in the ecologically vulnerable region of the Loess Plateau, China, t...
