Water erosion is a major problem in semi-arid region where decreases the dam reservoir design capacity, agricultural yield productivity, and increases other environmental impacts. This phenomenon widely predominant Morocco, particularly Oued El Malleh watershed Casablanca Settat region. Most soil happens gradually which makes it challenging to notice. Hence, monitoring of degradation under mode...

Daerah irigasi Jurug merupakan salah satu kawasan pertanian di daerah Kulon Progo. Penyediaan air untuk tersebut bersumber dari tampungan embung yang berada hulu tersebut. Beberapa tahun terakhir terjadi pendangkalan akibat sedimentasi mengakibatkan berkurangnya kapasitas embung, serta tertutupnya pintu intake penumpukan sedimen Analisis menggunakan model USLE memprediksi laju erosi lahan pada ...

The multitemporal behavior of soil loss by surface water erosion in the hydrographic basin of the river Mourão in the center-western region of the Paraná state, Brazil, is analyzed. Forecast was based on the application of the Universal Soil Loss Equation (USLE) with the data integration and estimates within an Geography Information System (GIS) environment. Results had shown high mean annual r...

The cover-management factor (C-factor) is important for studying soil erosion. In addition, it is important to use sampling plot data to estimate the regional C-factor when assessing erosion and soil conservation. Here, the loess hill and gully region in Ansai County, China, was studied to determine a method for computing the C-factor. This C-factor is used in the Universal Soil Loss Equation (...
