Human impacts on fluvial hydrosystems
1996For thousands of years rivers have been altered by many forms of human activity. Deliberate changes of fluvial hydrosystems have resulted from the power of technology to satisfy the many demands upon water resources. River regulation by dams for domestic and industrial water supply and for irrigation, which today often include intercatchment transfers,

Sustainability of Micro-Hydrosystems — A Case Study
Energy & Environment, 2009Energy development and management has been a crucial subject due to recent concerns of energy shortages and increasing oil prices. Energy is not only the major driver of economic development but also a major precursor for global environmental problems due to emission of pollutants including greenhouse gases.

Hydrological and geomorphological structure of hydrosystems
1996Chapter 4 described the basic mechanisms of river dynamics, emphasizing longitudinal and transverse variability in morphology and flows of water and material. This chapter applies information on river morphology and dynamics to examine the physical structure of hydrosystems.

Oscillations of Partially Dissipative Hydrosystems
2003In this chapter we consider the problem on small motions and normal oscillations of a hydrosystem consisting of two fluid layers each one of a different physical nature: The lower layer is a homogeneous, viscous fluid and the upper one is an ideal homogeneous fluid with a free surface.

Hydrosystems as Multipractice Phenomena
2016Given the water governance regime, how potent is the normative practice idea in the case of hydrosystems management? How can the normative practice framework explain the failure of the water governance of the Zayandehrud, and how can this explanation improve water governance both in thsi case and more generally?Can the govervance of the Zayandehrud be ...

The state of the left-bank anchor reinforcement of the Chirkeiskaya hydrosystem
Power Technology and Engineering, 2004The state of reinforcement anchors after 30 years of service at the hydroelectric power plant is described, and tension variations in the bars placed in adits caused by high humidity, breaking of welds, seismic, etc. are analyzed.

Analysis and Control for Hydrosystems under Uncertainty
WRPMD'99, 1999Hydrosystems are subject to uncertainty. This paper will attempt to answer three challenging questions associated with hydrosystems under uncertainty. The first one is how to perform model calibration and model validation. The second one is how to quantify uncertainty and risk. The third one is how to reduce uncertainty and risk.

Multiphase Modeling of Hydrosystems Using OpenFOAM
2018This paper presents three computational fluid dynamics applications regarding multiphase modeling of hydro systems with the open source software OpenFOAM. The first model investigates flow processes of groundwater and surface water using an integral approach which solves the three-dimensional Navier–Stokes equations, extended by the consideration of ...
