چکیده
Abstract This study presents the preliminary stage of development a conjunctive surface-subsurface model for simulating flow in swale. The surface is modelled by one-dimensional dynamic wave equation. To improve accuracy, third-order numerical scheme used to solve advection terms model. Meanwhile, subsurface as vertical through nondeformable porous media without air compression effect. At stage, and are verified separately. against experimental data runoff from simulated rainfall. showed promising performance reproduction hydrograph. overall discrepancy between result hydrograph discharge around 14%. For model, moisture profile soil Philip’s analytical solution. obtained shows 100% agreement with

آب حاصل از بارش منبع تأمین نیازهای بی شمار جانداران به ویژه انسان است و هرگونه کاهش در کم و کیف آن مستقیماً حیات موجودات زنده را تحت تأثیر منفی قرار می دهد. نوسان سال به سال بارش از ویژگی های اساسی و بسیار مهم بارش های سالانه ایران محسوب می شود که آثار زیان بار آن در تمام عرصه های اقتصادی، اجتماعی و حتی سیاسی- امنیتی به نحوی منعکس می شود. چون میزان آب ناشی از بارش یکی از مولفه های اصلی برنامه ...

deployable scissor type structures are composed of the so-called scissor-like elements (sles), which are connected to each other at an intermediate point through a pivotal connection and allow them to be folded into a compact bundle for storage or transport. several sles are connected to each other in order to form units with regular polygonal plan views. the sides and radii of the polygons are...
Heterogeneous Substructuring Methods for Coupled Surface and Subsurface Flow
The exchange of groundand surface water plays a crucial role in a variety of practically relevant processes ranging from flood protection measures to preservation of ecosystem health in natural and human-impacted water resources systems. Commonly accepted models are based on the shallow water equations for overland flow and the Richards equation for saturated–unsaturated subsurface flow with su...

Numerical Modelling of Coupled Surface and Subsurface Flow Systems
This paper presents and compares several numerical solutions of the coupled system of Navier-Stokes and Darcy equations. The schemes are based on combinations of the finite element method and the discontinuous Galerkin method. Accuracy and robustness of the methods are investigated for heterogeneous porous media. The importance of local mass conservation for filtration problems is also discussed.
