In this paper, development of a semi-two- dimensional mathematical model called SDAR is introduced. The model is composed of two principal modules of hydraulics and sediment transport. The newly developed SDAR model has a number of capabilities including determination of sediment transport rate, aggradation - degradation&#10calculation, longitudinal profile and lateral cross–sectional variation...

In order to increase the flexibility and performance of hydraulically actuated machines there is a demand for more intelligent controllers. This leads to a rapid increase in complexity of the control systems. To manage the complexity and to ensure reliability of these systems, adequate software development methods are needed. In this work, we propose a methodology for structured design of digit...

Elevated forest mortality has been attributed to climate change-induced droughts, but prediction of spatial mortality patterns remains challenging. We evaluated whether introducing plant hydraulics and topographic convergence-induced soil moisture variation to land surface models (LSM) can help explain spatial patterns of mortality. A scheme predicting plant hydraulic safety loss from soil mois...

The design of hydraulic systems is founded on deep physical connections. It needs creativity and, at the present time, it cannot be automated. Nevertheless, powerful design support in hydraulics is still possible. This paper presents a new view to the design of hydraulic systems and shows how sophisticated subtasks of the hydraulic design procedure can be tackled. We identify the “model synthes...

The aim of this paper is numerical and experimental study of the effects of flow hydraulics, pipe structure (particularly elastic behaviour) and submerged jet on leak behaviour. In this regard, experimental tests were performed on a high-pressure circulation set up. Experiments were performed on an old steel pipe and a High Density Polyethylene (HDPE) pipe discharged to the atmosphere in a wide...
