The linear form of the Muskingum model has been widely applied to river flood routing. However, a nonlinear relationship between weighted-flow and storage volume exists in most rivers, making use inappropriate. On other hand, application suffers from hydrologic parameters estimation. current study aims at presenting objective approach Nelder-Mead simplex (NMS) algorithm for purpose estimating model. performance this is compared with reported parameter estimation techniques together...
Abstract Iran's groundwater hydrochemistry has not been well understood. In this study, is evaluated using a rich, ground‐trusted data sampled from 9,468 wells distributed across the country in 2011. Twelve quality parameters were analyzed each sample, resulting 113,616 over study period. Examination of anions‐cations shows that concentrations sodium, calcium, chloride, and sulphate are higher than acceptable threshold for drinking‐use suggested by World Health Organization about 40%, 21%,...
Flooding is a common natural disaster that causes enormous economic, social, and human losses. Of various flood routing methods, the dynamic wave model one of best approaches for prediction characteristics floods during their propagations in rivers because all terms momentum equation are considered model. However, no significant research has been conducted on how sensitivity affects accuracy downstream hydrograph. In this study, comprehensive analysis input parameters was performed through...
Qanat is an ancient underground structure to abstract groundwater without the need for external energy. A recognized world heritage, has enabled civilization in arid and semi-arid regions that lack perennial surface water resources. These important structures, however, have faced significant challenges recent decades due increasing anthropogenic pressures. This study uses remote sensing investigate land-use changes loss of 15,983 shafts Mashhad plain, northeast Iran, during past six decades....
Environmental models are intended to represent or simulate natural environmental processes, often in mathematical statistical terms. Sensitivity analysis is a modelling tool that essential proper use of model because it enables the user understand importance variables and effects errors inputs on computed outputs. A few studies have reported sensitivity analyses flood routing parameters. In this study, parameters with implicit numerical method investigated through mathematical, field...
One of the key factors for flood modeling and control is hydrograph, which not always available due to lack discharge observations. In reverse flow routing, hydraulic or hydrological calculations are performed from downstream end upstream end. present study, a routing approach developed based on Muskingum model. The storage function conceptualized as linear five different nonlinear forms. Euler fourth-order Runge–Kutta numerical methods used solving models. shuffled complex evolution (SCE)...
Due to the importance of channel flow characteristics in water conveyance, study it is a noteworthy problem for hydraulics experts and much attempts has been accomplished modeling characteristics. One significant this respect secondary cells their effect on specifications. Widespread experimental analytical investigations have phenomenon. However, researchers are trying replace expensive time-consuming approaches ad hoc models with numerical simulation procedures using computational fluid...
Quantitative control and safe exploitation of water resources are crucial components for the sustainable development any region due to increasing scarcity, especially in arid semiarid regions. A proper management program Tabriz plain is necessary because groundwater excessive surface limitations. The present study aims develop a system dynamics (SD) model not only identify level fluctuations but also determine amount supply deficits municipal-industry agricultural uses by considering various...
Abstract The fine migration and the scale formation into porous media resulting production decline have long been problem to petroleum industry. It is also generally accepted that due particle movement are not thoroughly understood. In contributing solution of this problem, an experimentally study calcium sulphate in using packing bed with 12 different size glass sand bead 8 core plug gathered from Siri oilfields. purpose was physical mechanical aspects processes leading damage caused by...
A realistic new sediment–laden water prediction computer model was developed. In this unsteady non-uniform flow computations were incorporated. Using model, flooding flow–sediments simulated and compared to earlier research including hydrologic engineering centre (HEC-series) models. Uncertain value of parameters errors in flow–sediment transport equation existing coupled models studied. Sensitive nonlinear terms simplified linear state sediment laden flows loosed boundaries considered. The...
