The study investigated the simulation of flow characteristics over an Ogee-type spillway surface. This research utilizes a Flow-3D numerical model that builds upon findings from prior experimental data and models simulated by Ansys with k-epsilon turbulence model. It methods RNG LES to analyze rate, water profile, pressure, shear stress, velocity at seven points along spillway. reports strong agreement between model's results data, demonstrating accurately reflects physical behavior. As...
This study evaluates the effectiveness of Flow-3D numerical simulations in predicting scour profile, depth, and location downstream circular culverts under varying flow conditions. Two hydrographs with peak flows 13.8 l/s 20 were used to simulate unsteady Each hydrograph included seven different discharges, steady tests conducted at maximum rates observed during scenarios. examined subjected inlet blockages 0%, 25%, 50% compared result from utilizing Renormalization Group (RNG) turbulence...
For safe design of culverts, the estimation scour depth downstream culvert outlet is one most remarkable considerations. Poor culverts inevitably leads to destruction and increases expenditures on management rehabilitation. The objective this study investigate performance numerical models in predicting its location box unsteady flow conditions. Culverts with unblocked partially blocked outlets were used, predictions two turbulence methods, namely renormalization group (RNG) k-ε, compared....
Proper placement of dams along a river entails lot studies including the impact upstream dam on downstream and lands. In case inaccurate dams, flood arisen from failure break leads to breakage dams. this research, reservoir volumes two successive were optimized evaluate stability present decision basis for dams’ safety. To end, Vahdat located at Zhave dam, in Sirvan basin, Kurdistan province, Iran investigated. The HEC-RAS model was applied simulation routing following up reservoir. digital...
Due to growing concerns about global climate change and the role of carbon emissions as a contributing factor, numerous companies organizations are initiating "carbon footprint" projects assess their contributions change. This study aims employ comparative research design investigate footprint patterns within Sulaymaniyah city Kurdistan Region Iraq. To achieve this, survey samples were collected from strategically selected urban rural locations. The questionnaire was structured into four...
Missing values are a common problem faced in the analysis of hydrometric data. The need for complete hydrological data, especially data planning, development and designing hydraulic structures, has become increasingly important. Reasonably estimating these missing is significant modeling cycle. major objective this paper to estimate annual maximum by using artificial neural networks (ANN). Sixteen stations, with 28 years measurements, catchment area Sefidroud watershed north Iran were...
The use of complex piers to build bridges has become widespread. In this study the experimental data was obtained determine scour hole's dimension and its changes versus pile cap elevation. Five models with different geometry were used in experiments under clear water condition thresholds velocity. made an appropriate scale from real bridges. A 3D illustration model for each experiment drawn. length, width depth hole coordinates measured three directions. results showed that similar depth,...
