Flood is one of the natural hazards that its frequent occurrence has increased in the recent years and the damages of it, had affected apart of country in every year. Prioritization of sub basins has an important effect in watershed management. The purpose of prioritization of sub basins is offer a pattern for control and decrease flood hazards and evaluating the role of each sub basin in peak ...

The one-dimensional N ×N -matrix Chern-Simons action is given, for large N and for slowly varying fields, by the (2k + 1)-dimensional Chern-Simons action SCS , where the gauge fields in SCS parametrize the different ways in which the large N limit can be taken. Since some of these gauge fields correspond to the isometries of the space, we argue that gravity on fuzzy spaces can be described by t...
