Abstract:

Thesis (PhD (Civil Engineering))--University of Stellenbosch, 2005.<br>Estuaries are complex water bodies and differ considerably from fluvial river systems. In estuaries the flow reverses regularly due to the tidal currents and flow depths depend primarily on the tides and not the flow. An estuary has two sources of sediment: the river during floods and the ocean that supplies marine sediment through littoral drift which is transported by tidal currents into the estuary. Oversimplified models cannot be used to investigate the hydrodynamics and geomorphology of an estuary due to its compl

Abstract:

Simultaneous in-situ measurements of waves, currents, water depth, suspended sediment concentrations and bed profiles were made in a rip channel on Perranporth Beach, Cornwall, UK. Perranporth is a high energy beach (annual offshore Hs = 1.6 m) which is macro-tidal (mean spring range = 6.3 m) and the grain size is medium sand (D50 = 0.28 – 0.34 mm). It can be classified as a low tide bar – rip beach and exhibits a relatively flat inter-tidal zone with pronounced rhythmic low tide bar - rip morphology. Data were collected over two field campaigns, totalling 14 tidal cycles and including 27 occu

Abstract:

Blowouts are erosional depressions that occur on pre-existing vegetated sand deposits. Their morphodynamic behaviour can reflect changes in anthropogenic activity, climatic conditions and animal behaviour; however patterns of deflation are poorly understood as near-surface airflow is complex. Previous research has indicated that flow is topographically manipulated as it moves through the landform, causing steering, reversal and jetting of the airflow. However, empirical data on these effects have been limited due to inadequacies in anemometer and sediment trap deployments. As a consequence kno

A nested three dimensional numerical modeling application was developed to determine the fate of pathogen indicators in Lake Pontchartrain discharged from its tributaries. To accomplish this, Estuarine, coastal and ocean model with sediment (ECOMSED) was implemented to simulate various processes that would determine the fate and transport of fecal coliform bacteria in the lake. The processes included hydrodynamics, waves, sediment transport, and the decay and transport of the fecal coliforms. Wind and tidal effects were accounted along with the freshwater inflows.

Rivers sourced in the Himalayan mountains support more than 10% of the global population, where the majority of these people live downstream of the mountain front on the alluvial Indo-Gangetic Plain. Many of these rivers however, are also the source of devastating floods. The tendency of these rivers to flood is directly related to their large-scale morphology. In general, rivers that drain the east Indo-Gangetic Plain have channels that are perched at a higher elevation relative to their floodplain, leading to more frequent channel avulsion and flooding. In contrast, those further west have c

Schemes to restore fish habitat in rivers often involve installing instream structures such as current deflectors to create and maintain riffle-pool sequences.

Natural rivers exhibit many complexities that need to be taken into account when implementing instream structures.

Abstract:

The Binga reservoir was rapidly filled with sediments due to an underestimation of the sediment load and the absence of any sediment management strategy. The Binga reservoir is gradually losing its remaining ability to regulate the flow of Agno river as the water storage capacity is reduced year by year due to sedimentation. The sediment inflow is expected to increase over the coming years because the sedimentation that takes place in the upstream reservoir, Ambuklao reservoir, and its associated reduction of sediment trapping efficiency will increase the sediment load released to Binga reserv

Abstract:

Riverine sediments play a fundamental role within the fluvial system, since they represent potential removal zones of stream-borne pollutants and, in particular, nutrients derived by anthropogenic activities. The region of sediments where the exchange and mixing of surface and subsurface waters occurs is the hyporheic zone. This region is also a place of intense biogeochemical activity, influencing both the flora and the fauna living in the fluvial environment. In the last decades several works were focused either on the water exchanges or the biochemical reactions in the hyporheic zone but ju
