The collocation approach to Moho estimate
Moho Gravity collocation Gravimetric inverse problem
2015/8/17
In this paper, the collocation approach to Moho estimate is presented. This method is applied to the inversion of gravity data that can be complemented by Moho depth information coming from e.g. seism...
A high-order conservative collocation scheme and its application to global shallow-water equations
conservative collocation scheme global shallow-water equations
2015/3/5
In this paper, an efficient and conservative collocation method is proposed and used to develop a global
shallow-water model. Being a nodal type high-order scheme,
the present method solves th...
