The Peshawar basin is situated along the junction of the northern margin of the IndoGangetic foredeep and the southern margin of the Hindu Rush-Himalayan Ranges. During the late Cenozoic, southward encroachment of tectonic disruption into the foredeep terminated molasse deposition and delineated the Peshawar intermontane basin through uplift of the Attock Range along the southern margin of the ...

hydraulic jump on adverse stilling basin is an unstable phenomenon which causes some complexities in controlling of the   jump. this paper considers the stability of free hydraulic jump on adverse stilling basins from a theoretical point of view. a minimum value of upstream froude number is needed to produce the free hydraulic jump on adverse stilling basins which was presented by a theoretical...

The Weather Research and Forecasting model is used to perform large-eddy simulations of thermally driven cross-basin winds in idealized, closed basins. A spatially and temporally varying heat flux is prescribed at the surface as a function of slope inclination and orientation to produce a horizontal temperature gradient across the basin. The thermal asymmetry leads to the formation of a closed ...

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 ...

A case study of the Sacramento Basin is undertaken to examine problems of planning for the impacts of climate change on water resources utilizing output from general circulation climate models. This work provides a sensitivity analysis linking climate, stream ̄ow, and planning decisions. Water resource planners want reliable time series of stream ̄ow in the basin. Sacramento basin hydrological mo...

In this paper the spectrum of barotropic basin modes of the Argentine Basin is shown to be connected to the classical Rossby basin modes of a flat-bottom (constant depth), rectangular basin. First, the spectrum of basin modes is calculated for the Argentine Basin, by performing a normal-mode analysis of the barotropic shallow-water equations. Then a homotopy transformation is performed that gra...

In this paper we propose a numerical method to calculate basin bifurcation sets in a parameter space. It is known that the basin bifurcations always result from the contact of a basin boundary with the critical curve segment. A numerical example for a two-dimensional quadratic noninvertible map is illustrated and new results of basin bifurcations are shown.
