Slope farmland is prone to soil erosion, especially in sub/tropical regions. However, our understanding of near-surface hydrology characteristics and their controlled factors red sloping remains limited. Here, we conducted simulated rainfall experiments assess the impact pattern, straw mulching, structure on hydrological processes southern China. Results showed that: (1) short duration-high int...

A fundamental objective in studies of climate-erosion-tectonics coupling is to document convincing correlation between observable indicators of these processes on the scale of a mountain range. The eastern Himalayas are a unique range to quantify the contribution of tectonics and climate to long-term erosion rates, because uniform and steady tectonics have persisted for several million years, w...

Erosion is one of the most destructive and continuous phenomena that cannot be prevented and only could be controlled by studying the chemical and physical properties of soil. Marls are one of the most important sedimentary units in Iran which have high rate in sediment production and erodibility because of their Physico-chemical characteristics. These properties caused large environmental and ...

We present a new real-time hydraulic erosion simulation for Computer Graphics. In our system water runs over the surface and disintegrates the underlying layer of soil. The grit is simulated as a fluid with higher viscosity and moves on the ground of the water pool. When water evaporates, or the dissolved soil exceeds a critical level, the dissolved matter is deposited back on the ground for ac...

in recent decades, large investments have been made to introduce soil conservation methods, but most of these efforts have had limited success in achieving the goals. as a result, attempt to identify the factors deterring or promoting adoption of soil conservation practices is important. therefore, this study aimed to investigate factors affecting adoption of soil conservation practices by rain...

The coast of the provinces of Granada and Malaga (SE Spain) are economically important areas for the subtropical fruit cultivation. The climate is characterized by heavy periodic rainfall, which is one of the main factors responsible for soil erosion in this agroecosystem. However, the erosion depends on a host of factors, including soil, topography, cropping and soilconservation techniques. Th...

introduction rainfall erosivity, the propulsion or power of causing erosion in separation and transport of soil particles, is in relation to water erosion. rainfall erosion is causing loss of soil, damage to agriculture and infrastructures which is followed by water pollution. changes in rainfall patterns exacerbate risk of erosion globally. rainfall erosivity plays an effective role in soil er...
