“…This procedure makes sure the conservation of mass and momentum, is extremely flexible and conceptually simple. Numerous researchers have applied FVM to real case studies simulated water propagation over arbitrary topographies, [7][8][9][10][11][12]. Besides, the numerical simulation of natural case study is characterized by several problems, such as: complex geometry, high roughness coefficient or wet/dry front.…”

“…The complicated geometry may generate unphysical solution in simulating flood flow propagation. Thus, a stable algorithm, can work with two dimensional domain and provide shock-capturing capability is necessary, [7]. Therefore, in this article, FVM with Godunov type is utilized and Flux Different Splitting Method (FDS) is invoked in order to make the exactly balance between fluxes terms and source terms.…”

The paper is dedicated to study a numerical model simulating dam-break based on two dimensional nonlinear shallow water equations (2D-NSWE). Finite Volume Method-Godunov type is applied to discretize this equation. Roe scheme is utilized to approximate Riemann problem, meanwhile method of flux difference splitting is implemented to construct numerical solvers of SWE. Besides, the semi implicit scheme is also invoked to solve friction term in case of high roughness coefficient. The proposed model is verified through a comparison between computed results and empirical data of two reference tests. A dam break flow over floodable area with different roughness coefficients is also researched. A total collapsed dam scenario of an arch dam-Nam Chien in Vietnam is simulated by the proposed model. Several hydraulic characteristics such as flood extent, arrival time and time histories of water depth at different gauges are estimated with different grid sizes.

Temporary migrant workers, globalization, 20th century to present

Temporary labor migration is the phenomenon of workers migrating on the basis of temporary work authorizations, which attach the legal status of workers to particular employers and/or particular positions of employment. Temporary labor migration schemes take on various forms: from bilateral and regional agreements for the exchange of labor between states, to changes in national legislation allowing employers easy and accelerated access to temporary migrant workers for varying time periods, to provisions in multilateral trade agreements such as Mode IV of the World Trade Organization's General Agreement on Trade in Services. While labor migration has been a recurring phenomenon in human history (Potts 1990; King 1996), what is new in the post‐1970 period of restructuring in the world capitalist economy is the increased use of temporary migrant labor by employers around the world and state facilitation of this shift.
