Channel flow routing provides information on the movement of flood wave as it travels downstream. From the flood forecast viewpoint, it is desirable to have some knowledge about the expected arrival time of peak flow. However, many parameters involved in the flow routing model, in reality, can not be quantified with certainty. In this paper, a probabilistic analysis using the Mellin transform i...
abstract: in the paper of black and scholes (1973) a closed form solution for the price of a european option is derived . as extension to the black and scholes model with constant volatility, option pricing model with time varying volatility have been suggested within the frame work of generalized autoregressive conditional heteroskedasticity (garch) . these processes can explain a number of em...
The Water Erosion Prediction Project (WEPP) model is a process-based, continuous-simulation, watershed hydrology and erosion model. It is an important tool for water erosion simulation owing to its unique functionality in representing diverse landuse and management conditions. Its applicability is limited to relatively small watersheds since its current version does not simulate flow in permane...
The interaction between groundwater (GW) and surface water (SW) not only sustains runoff in dry seasons but also plays an important role river floods. Lateral inflow is the recharge of to during a flood; this part GW-SW exchange. Hydrological engineers proposed idea modelling flood routing using Muskingum-Cunge method, which exchange fully considered. This study proposes improved nonlinear mode...
Heuristic search algorithms, which are characterized by faster convergence rates and can obtain better solutions than the traditional mathematical methods, are extensively used in engineering optimizations. In this paper, a newly developed elitist-mutated particle swarm optimization (EMPSO) technique and an improved gravitational search algorithm (IGSA) are successively applied to parameter est...
Hydrological models for evaluating and predicting the amount of available water in basins, flood frequency analysis, and developing strategies to deal with destructive floods are expanding daily. In this study, HEC-GeoHMS and Arc Hydro extensions in ArcGIS software and the HEC-HMS model were used to simulate design flood hydrographs in the Aydooghmush basin in the northwest of Iran. SCS-CN, SCS...
Title of Thesis: UNCERTAINTY AND SENSITIVITY ANALYSES OF THE MUSKINGUM-CUNGE CHANNEL ROUTING MODEL Stephen Scott Reid, Master of Science, 2008 Thesis directed by: Professor Richard H. McCuen Department of Civil and Environmental Engineering Two widely used channel routing models are the Muskingum and MuskingumCunge (M-C) models. However, no significant research has been conducted on how input p...
Dam-break is a serious disaster resulting in severe damage to downstream communities. Therefore, analyzing the affected range and evolution process of dam-break floods advance valuable. However, difficulties challenges lie complexity breaking earth-rock dams, uncertainty floods, geographical variability. Given this, objective this study analyze characteristics flood evolution. The chooses Cheng...
