Project Imbituba

The Port of Imbituba, located in the state of Santa Catarina, Brazil, is a privately operated port in Brazil. In the past, the port has been upgraded in order to meet the future growth in the size and number of vessels. The main breakwater and the quay were elongated and the waterway was deepened. In the first six months of 2014, a large...

Valdivia Estuary Project

Valdivia is a Chilean city located near an estuary system, 800 km south of Santiago. The navigation capacity of the Valdivia river mainly determines the present state and future possibilities for the welfare of the city. Since sedimentation problems arose in the river, the capacity for navigation became limited. The ministry of Valdivia...

Numerical modelling of sedimentation in Trailing Suction Hopper Dredgers

Damen Dredging Equipment is a yard dedicated to the dredging industry. The yard specializes in the design, manufacture and supply of a wide variety of dredging tools. One of the tools Damen offers is the Trailing Suction Hopper Dredger(TSHD).<br/><br/>The performance of such a TSHD is described by its production: the amount of sediment loaded in...

Undesirable sedimentation in the Magdalena River around the City of Barrancabermeja: The quest for an efficient solution

The reach of the Magdalena River around the city of Barrancabermeja experiences large issues concerning its navigability since the construction of the Yondó Bridge. The purpose of this study is to investigate possible causes of this poor navigability and to come up with an improvement to the current situation. The influence of bars and scour...

Incremental Pixlation landscape: sea change/see change, Richmond shipyard Redevelpment project

In the face of rising waters and increased stormrelated flooding, communities will have to decide what to do with their flood-prone areas. Continually repairing storm damages and providing services to these vulnerable neighborhoods demands significant government resources. For these areas, cities have three major options to consider: keep water...

Restoration of sediment regimes by modifying dam operations: Case study: The Volta Delta, Ghana

Despite the many positive effects of dams, they can also have several negative impacts on natural systems. One of these impacts is the decrease in sediment inflow towards the coast which can lead to coastal erosion. <br/>A technique that can be applied to improve the situation downstream is modifying the discharge through the dam. Unfortunately,...

Socio-Hydrology of Keduang Sub-basin in Central Java, Indonesia using case study approach: Understanding the relation between hydrology of Keduang sub-basin and social aspects using qualitative case study

Since coined in 2011, socio-hydrology studies have been dominated with mathematical models developed by mostly hydrologists, which often did not take social aspects into account so seriously. Some people argued that more attention into the social part of socio-hydrology should be given, because often the social aspects were too oversimplified....

Modelling the influence of variability on the sediment dynamics in Canal Emilio Mitre: A study on the effect of climate, deepening and wind scenarios on a navigation channel through the Rio de la Plata estuary

Canal Emilio Mitre is a navigation channel that runs through the Rio de la Plata estuary in South America. It grants access to the second largest inland waterway system in South America, covering (parts of) Argentina, Uruguay, Brazil, Paraguay and Bolivia. The channel is a main bottleneck for navigation for two reasons; the channel has a...

Revaluation of dredging costs in reservoirs and its impact on reservoir financial performance

The research focuses on sedimentation in reservoirs. Subjects include settling distribution in a reservoir, dredging and flushing of sediment in reservoirs, impact of sedimentation on reservoir performance and financial effects of long term sedimentation in reservoirs.

Determination of the removal efficiency of a decentralized stormwater treatment system: A theoretical approach to assess a modified SediSubtrator L

Due to the predicted impacts of climate change on the frequency of storm events, water managers are challenged to improve and adapt the current urban infrastructure. Cities need to be able to deal with the adverse effects due to more frequent and heavier rainfall. This implies the need for sustainable urban drainage systems (SUDS) that can deal...

Understanding Sedimentation Trajectories and Social Relations with Agent-based Modeling of Sudan’s Gezira Scheme

Seed-sediment Dynamics: An experimental study into the behaviour of seagrass seeds in a sand mixture informing a novel approach for large scale seagrass restoration

<br/>In response to the sharp decline of seagrass globally, various restoration techniques have been developed and applied; many at limited scale and with limited success. This research focuses on the fluid mechanics and behaviour of seagrass seeds in a sand mixture through physical laboratory experiments. The objective is to establish a...
