A common way to transport solids in large quantities is by using a carrier fluid to transport the solids as a concentrated solid/liquid mixture or slurry through a pipeline. Typical examples are found in dredging, mining and drilling applications. Dependent on the slurry properties and flow conditions, horizontal slurry pipe flow is either in...

Aquatic community dynamics are closely dominated by flow regime and water quality conditions, which are increasingly threatened by dam regulation, water diversion, and nutrition pollution. However, further understanding of the ecological impacts of flow regime and water quality conditions on aquatic multi-population dynamics has rarely been...

The need to curb CO2 emissions has led to an increase in the utilization of CCS systems. These systems use pipelines for the transport of CO2. It is preferred that CO2 be transported in it’s dense form. But, this is not always the case as the phase in which CO2 exists is based on the operating conditions. In some cases, multiphase CO2 is...

Freshwater is a finite resource. It offers goods and services of fundamental importance for the development of human societies. In the developing countries, water-related infrastructure developed rapidly, which will bring prosperity to an impoverished country but also risks compromising the sustainability of the environment. The scarcity of...

Experimental investigation of swirling vertical gas-liquid flow regimes. Different columnar flow patterns were observed and were used to construct flow regime maps. Four swirl elements were used to investigate the effect of swirl intensity on the flow regimes. An attempt was made to model the transitions between these columnar flow patterns.

Intensive and incessant disruptions in watercourses such as dams are taking place due to the growing demand for hydroelectric generation, and can result in severe deterioration of ecosystem integrity. This research concentrates on the impact of dams on macroinvertebrate communities downstream of two hydropower dams on tributaries of the upper...

Hydrological methodologies are the most efficient approaches for environmental flow (eflow) assessments. This paper presents a hydrological methodology for determining eflows in rivers with scarce development to promote proactive environmental water allocations that limit flow alteration and unsustainable water use. The analysis includes the...

Environmental flows (e-flows) science has significantly advanced in the last decades. In Mexico, a standard for e-flow assessments was recently published as a regulatory instrument to support water planning and management. However, the appropriateness of the technical procedure in a climate change context has not been investigated. Do the e...

Slurry transport is a very important means of transporting solids through a pipeline. To improve the efficiency of slurry transport, especially in coarse particle transport, which is subject to problems such as strong resistance and easy blockage, more of the internal structure of the flow must be known. Empirical and analytical models are...

Different approaches are present in literature for slurry transport in inclined pipes. Most models assume that the socalled solids effect, the hydraulic gradient of the mixture minus the hydraulic gradient of the carrier liquid, has to be multiplied by the cosine of the inclination angle to a certain power. These powers vary from 0.25 to 1.7. In...

The Middle Zambezi, host to a rich biodiversity, is located in the central part of the Zambezi River Basin which covers eight Southern African Countries. The area is located downstream of three hydropower schemes. In the last decades, the floodplain riparian tree, the Faidherbia albida, vital for the local wild life, has shown a worrying...

Flooding of an area can be described mathematically and by the use of scale models. The different flow regimes can be discerned using the scale model and then these regimes can be modelled using mathematical relations. This mathematical description can then be used to design simulation computer code for such a flooding. The first part ofthis...
