For the computation of the morphological changes on reservoir beds, in scale model experiments, a hydrodynamic model is combined with the sediment continuity equation. The hydrodynamic model is based upon the equations of mass and momentum conservation. The sediment transport capacity appearing...

Grazing leads to the reduction of biomass and plays a critical role in land degradation in arid and semiarid lands. However, the indirect effects of grazing on the ecosystem, e.g., the effect on seed dispersal, have not been well understood. In this study, we built an agent-based model (ABM) to...

The European Union designates 26% of its landmass as a protected area, limiting economic development to favor biodiversity. This paper uses the staggered introduction of protected-area policies between 1985 and 2020 to study the selection of land for protection and the causal effect of...

This paper analyzes the regional differences in dust weather and its relationship with climatic factors and vegetation cover, using data at 27 observation stations in the Beijing-Tianjin Sand Source Region from 1960 to 2007. There was a decreasing trend in dust weather in the southeast, which...

The 2004 Indian Ocean tsunami had a significant impact on the Tamil Nadu coast in India. In this paper, a range of field survey data collected by different survey teams available in literature have been analyzed and compiled to serve as a basis for validation of numerical tsunami simulations....

A very severe cyclonic storm ‘Thane’ developed over the Bay of Bengal during 25–30 December 2011, crossed the Tamilnadu coast between Pondicherry and Cuddalore (southeast coast of India) in early hours of 30 December with a wind speed 120–140 km/h. The offshore tide record reveals that...
