Introduction: Estimations of peak discharge rates and durations of floods will play critical roles in discussions about megafloods and their relevance to the history of water on Earth and Mars. However, the movement of the floodwater is not easily modeled in an exact form because it strongly correlates to turbulent forces. In addition to that, actual floods progressively inundate complicated ro...

Development of rural areas in rivers margins and flood plains, without understanding and attention to the dynamical and hydrological conditions and upstream areas of the rivers will cause to increase flood risk and loss of life and financial. Flood zoning has many applications, in floodplain management. For management of the three major branches of the Halilrood River, Rabor, Roodar and Javaran...

An intelligent method based on adaptive neuro-fuzzy inference system (ANFIS) for identifying Manning’s roughness coefficients in modeling of alluvial river is presented. The procedure for selecting values of Manning n is subjective and requires judgment and skill which are developed primarily through experience. During practical applications, researchers often find that a correct choice of the ...

abstract ground water flow and skin is the most important phenomenon in the process streams are involved not only in the face of the whole earth, but also of the life of man on earth can. degradation of coastal erosion, lateral stability and continuity in iran and around the world each year destroys fertilized agricultural lands around the river, coastal installations, bridges, and is general h...

The Manning friction coefficient as a one-dimensional (1D) openchannel flow parameter is determined from a series of two-dimensional (2D) simulations of the flow on steep slopes using a computational hydraulic solver derived from a minimal intervention strategy (MIS2D). Computations are also conducted for the oblique dam-break waves to evaluate the performance of MIS2D. The results are compared...
