“…Refsgaard et al [17] incorporated an existing 1-D model into an integrated modeling system subsequently applied on the Danubian Lowland [17]. Islam et al [11] established a model for steady and unsteady flow simulation in an irrigation canal network [11], capable of handling different hydraulic structures (weirs, gates, falls, pipe outlets, imposed discharges and computation of gate openings). Other applications of one-dimensional open-channel flow models include longterm simulations [16], river network modeling [10], flood predictions and similar hydraulic engineering problems.…”

This paper presents the development, calibration and verification of a looped river network model. After introducing the governing equations, the established numerical model is calibrated employing measurements conducted on the Danube River and its two main tributaries in Serbia, the Sava and Tisa rivers. The calibration is done by altering the Strickler's coefficient using three different approaches, assigning a constant value of the coefficient in a cross section, setting the coefficient as a function of discharge and, finally, connecting the Strickler's coefficient to local depth. The verification is conducted by comparing the computed results, for all three of the considered methods, with measurements for the time interval from January 1st to December 31st of the year 2006. Careful examination of the obtained results helped to select the most suitable calibration method for future reference. The selected approach gave better agreement of computed and measured values, has a clear physical explanation and enables faster and easier calibration.

“…Tsinghua University favoured this trend and developed robust gate controller [21] and model to optimize gates operation [22]. Actually, the control scheme was generally applied in combination with channel flow simulation model before putting into practice [23]. Existing simulation model represented by Canal CAD, Mike 11 and Sobek [24] could simulate the complex hydraulic behaviour without guarantee of success, since those programs always fail to account for specific structural or rigorous operational setting of the project.…”

The particular challenges of modeling control systems for the middle route of the south-to-north water transfer project are illustrated. Open channel dynamics are approximated by well-known Saint-Venant nonlinear partial differential equations. For better control purpose, the finite difference method is used to discretize the Saint-Venant equations to form the state space model of channel system. To avoid calculation divergence and improve control stability, balanced model reduction together with poles placement procedure is proposed to develop the control scheme. The entire process to obtain this scheme is described in this paper, important application issue is considered as well. Experimental results show the adopted techniques are properly used in the control scheme design, and the system is able to drive the discharge to the demanded set point or maintain it around a reasonable range even if comes across big withdrawals. the south-to-north water transfer project, control scheme, Saint-Venant equations, model reduction, pole placement Citation: Shang Y Z, Liu R H, Li T J, et al.

“…A conventional approach to numerical modeling of flows in channel networks is to treat junctions as internal boundaries as well, though Larson et al (1971) have discussed the characteristic equations for junctions. The water stage equality model, shown by Akan and Yen (1981), is widely used for junctions with implicit models using the finite difference method (Joliffe 1984;Choi and Molinas 1993;Nguyen and Kawano 1995;Jha et al 2000;Islam et al 2005Islam et al , 2008 and the finite element method (Szymkiewicz 1991;Kawachi et al 1994). Aral et al (1998) treated junctions of open-channel networks in an explicit finite volume scheme using the water stage equality model together with the characteristic equations.…”

Analysis of runoff processes in farmlands during storm events in particular is an important engineering topic. The shallow water equations describing the physical conservation laws are attractive tools for understanding motion of surface water. A numerical model is developed to reproduce surface water flows during storm events, using the finite element method and the finite volume method applied to the one-dimensional shallow water equations. The numerical model has the advantage of dealing with transcritical flows, wet, and dry processes, irregular channel bed slopes, and channel junctions involving multiply connected networks. Standard numerical tests demonstrated some of these features. Runoff processes from farmlands in a Japanese hilly area is analyzed with the numerical model coupled with another runoff model of black-box type. Parameters of the models are calibrated and validated using observed series of rainfall and runoff discharge data. Simulated results included submergence of hydraulic jumps and flood storage in farming plots, which are very informative in terms of assessing diverse functions of the farmlands.
