Abstract:
Many features of real granular fluids under rapid flow are exhibited as well by a system of smooth hard spheres with inelastic collisions. For such a system, it is tempting to apply standard methods of kinetic theory and hydrodynamics to calculate properties of interest. The domain of validity for such methods is a priori uncertain due to the inelasticity, but recent systematic studies continue to support the utility of kinetic theory and hydrodynamics as both qualitative and quantitative descriptions for many physical states. The basis for kinetic theory and hydrodynamic descriptions is discu

Abstract:
Low-crested (LC) rubble mound breakwaters are used for coastal protection. The main advantage of these structures is their mild aesthetic impact on the natural environment. As the waves approach and transmit over these structures, significant hydrodynamic processes occur in their proximal area, such as wave breaking, wave reflection, wave overtopping and transmission (Garcia et al., 2004). Many researchers have studied the hydrodynamics of flow in the vicinity of such structures, as well as the influence of their geometrical characteristics on the flow field.

Abstract:
The first part of the chapter presents general and specific issues concerning the use of hydroinformatic tools in hydraulic modeling as important step in decision-making activities in extreme situations such as floods. The special importance of these issues is the fact that currently cannot conceive a project related to water management without the use of computer modeling / simulation. It is shortly presented the usual simplified schematizations of real flow systems which are applied usually for flood modeling: one-dimensional (1D), two-dimensional (2D) or her combination. Based on the general principles of continuum mechanics the fundamental equations of hydrodynamics are deducted which stay on base of the river modeling. For the 1D schemes discussed the particular forms of the basic equations. To illustrate the above explanations in the next section modeling applications for several representative case studies will be presented using three known hydrodynamic/ hydrological modeling packages, namely DUFLOW, HEC-RAS, MIKE-11.

Abstract:
Gas–liquid–liquid reactors are typically found in bioprocess setups such as those used in alkane biocatalysis and biological gas stripping. The departure of such reactors from traditional gas–liquid setups is by the introduction of a secondary (dispersed) liquid phase. The introduction of the latter results in complicated hydrodynamics as observed through measurements of velocity fields, turbulence levels and mixing times. Similarly, changes in mass transfer occur as observed through measurements of gas hold up, bubble diameters and the volumetric mass transfer coefficients. The design and analysis of such reactors thus requires the adoption of an approach that can comprehensively account for the various observed changes. This chapter proposes Computational Fluid Dynamics as an approach fit for this purpose. Key considerations, successes and challenges of this approach are highlighted and discussed based on a review of previously published case studies.

Abstract:
This chapter presents a flood risk management system for vehicles at roadways, developed from extensive experimental and numerical studies on the impact of flash floods towards vehicle instabilities. The system, easily addressed as FLO-LOW, developed to contradict the assumptions that a vehicle would be able to protect the passengers from the flood impact. Herein the hydrodynamics of flows moving across these roads coupled with the conditions of a static car that would result in vehicle instabilities has been studied. In an attempt to prevent fatalities in commonly flooded areas, permanent structures are installed to warn users regarding water depth at the flooded areas. The existing flood monitoring system only focuses on water conditions in rivers or lake in order to determine risks associated with floods. Thus, there is a need for a better system to understand and quantify a mechanism to determine hydrodynamics instability of a vehicle in floodwaters. FLO-LOW enables the road users to input their vehicle information for a proper estimation of safety limits upon crossing the flood prone area. Preferably, the system enables road users to describe and quantify parameters that might cause their vehicles to become vulnerable to being washed away as they enter the flooded area.

Abstract:
We illustrate growth phenomena in two-dimensional cellular automata (CA) by four case studies. The first CA, which we call Obstacle Course, describes the effect that obstacles have on such features of simple growth models as linear expansion and coherent asymptotic shape. Our next CA is random-walk-based Internal Diffusion Limited Aggregation, which spreads sublinearly, but with a shape which can be explicitly computed due to hydrodynamic effects. Then we propose a simple scheme for characterizing CA according to their growth properties, as indicated by two Larger than Life examples. Finally, a very simple case of Spatial Prisoner’s Dilemma illustrates nucleation analysis of CA. In essence, analysis of growth models is an attempt to study properties of physical systems far from equilibrium (e.g., Meakin [34] and more than 1300 references cited in the latter). Cellular automata (CA) growth models, by virtue of their simplicity and amenability to computer experimentation [25], have become particularly popular in the last 20 years, especially in physics research literature [40, 42]. Needless to say, precise mathematical results are hard to come by, and many basic questions remain completely open at the rigorous level. The purpose of this chapter, then, is to outline some successes of the mathematical approach and to identify some fundamental difficulties. We will mainly address three themes which can be summarized by the terms: aggregation, nucleation, and constraint-expansion transition. These themes also provide opportunities to touch on the roles of randomness, monotonicity, and linearity in CA investigations. We choose to illustrate these issues by particular CA rules, with little attempt to formulate a general theory. Simplicity is often, and rightly, touted as an important selling point of cellular automata. We have, therefore, tried to choose the simplest models which, while being amenable to some mathematical analysis, raise a host of intriguing unanswered questions. The next few paragraphs outline subsequent sections of this chapter. Aggregation models typically study properties of growth from a small initial seed. Arguably, the simplest dynamics are obtained by adding sites on the boundary in a uniform fashion.

Анализ водопользования рисосеющих агрокомплексов в зоне Нижней Кубани свидетельствует о напряженной водохозяйственной ситуации, обостряющейся в маловодные годы. Возникающие дефициты водообеспечения наносят существенный ущерб всем водопользователям и особенно отраслям сельского хозяйства. Предлагаемые авторами подходы совершенствования водообеспечения и водопользования оросительных систем базируются на разработке интегрированной системы управления распределением водных ресурсов и продуктивностью агромелиоративного комплекса. Новая технологии управления строится на двух взаимосвязанных оптимизационных задачах, решаемых в одном пространственном и временном формате: с помощью динамической гидравлической модели формируются и изучаются оптимальные варианты подачи поливной воды от водоисточников до орошаемого поля, а модели продуктивности отражают влияние параметров водоподачи на урожайность культур. Гидродинамическое моделирование позволяет формировать режимы работы водохранилищ и гидроузлов таким образом, чтобы с одной стороны обеспечить командные высоты на водозаборах, а с другой, удовлетворить конфликтующие интересы водопользователей, в том числе сельхозпроизводителей.

Occurring water supply deficits cause significant damage to all water users and especially to agricultural sectors. The approaches proposed by the authors to improve water supply and water use of irrigation systems are based on the integrated management system for the water resources distribution and productivity of the agro-reclamation complex development. The new management technology is based on two interrelated optimization problems that are solved in the same spatial and temporal format: optimal options for irrigation water supply from water sources to an irrigated field are formed and studied using a dynamic hydraulic model, and productivity models reflect the influence of water supply parameters on crop yields. Hydrodynamic modeling allows you to form reservoirs operating and hydroelectric facilities modes in such a way that, on the one hand, provide command heights at water intakes, and on the other, meet the conflicting interests of water users, including agricultural producers. The development of an acceptable management decision is realized by using the methods of multi-criteria analysis and the theory of trade-offs with a focus on the forecast of crop deficit depending on the water allocation option.

Abstract:
The Arctic ocean has been the focus of increasing activities in oil and gas, marine traffic and fisheries as the resources in the Arctic area becomes more attractive for exploitation. There have been several studies on the response of ships and structures in ice covered waters, mainly for oil and gas applications. This paper presents a scenario simulation model for fisheries, crab pot retrieval, in partially ice covered waters. Snow crab fisheries in the Barents Sea is an ongoing commercial activity where partial ice covers may drift over crab pots which need retrieval. This scenario is unique

Abstract:
Abstract Specific engineering tools are used to design Floating Offshore Wind Turbines (FOWT). These so-called aero-hydro-servo-elastic solvers simulate the coupled behaviour of the turbine subjected to wind with the floater motion due to waves, including elasticity of the whole structure. The implemented hydrodynamic forces rely on a strong Oil&amp;Gas background and include potential flow theory and empirical laws, such as Morison forces. The undergoing study aims at re-evaluating the validity range of such theories, when applied to FOWT. To do so, CFD simulations will be run to model wave p
