This study is an analysis of sand mining in the Vietnamese Mekong Delta (VMD) with the use of the optical satellite data set PlanetScope. This is done with a detection and classification model of sand mining vessels in the VMD. The classification model is based on machine-learning and it is trained with three classes: sand mining vessels, other...

Human interventions in the White Volta River in Ghana increase the flood risk in living spaces of the local communities, causing great challenges in the area. Burkina Faso has built a hydropower dam near the border with Ghana which has a large impact on the discharge extremes of the White Volta River. As a result of poor water management of this...

The beach at Ngapali, Myanmar is eroding, resulting in a shoreline which moves landward. The coastline gets closer to the vegetation each year and during the monsoon season, at high tide, it reaches the palm trees completely. The assumption is that this is due to people shovelling truckloads of sand from the beach to use for construction, this...

The potential ecological effects of the sand mining activities for Maasvlakte 2 have been identified in an Environmental Impact Assessment (EIA). One of the identified effects in this EIA was an impact on the number of sea ducks in the Natura 2000 area 'Voordelta'. The sand mining activities will cause an increase of the silt concentration along...

The expected major increase in marine aggregate extraction in the future will increase the spatial and temporal environmental impacts. Coastal zone management and interdisciplinary surveys and assessments will become increasingly important in order to minimise impacts of largescale sand mining on marine resources and to resolve conflicts against...

This Master thesis is accomplished at the Rijksinstituut voor Kust en Zee (RIKZ) as part of KUST2005, which is a morphological research programme of Rijkswaterstaat (RWS). The management question of RWS (Directie Noordzee, DNZ) concerns the effects of large-scale (> 10x106 m3) sand extraction on the Zeeland ridges. DNZ wants to gain knowledge on...

Massive mining of sand from the middle and lower shoreface (depths of 10-30 m) in large-scale mining and borrow pits will be required in future in many European countries to nourish coastal beaches and dunes in response to increased coastal erosion due to expected sea level rise. The offshore mining of sand will require fundamental knowledge of...

Experimental results are very important to understand the complex nature of sand transport. They give insight in the relevant processes and can be used to validate model concepts. Most of the laboratory experiments on wave-related transport processes are carried out in oscillating water tunnels and in wave flumes. There are large-scale and small...

For several years the large-scale mining of sand from the Dutch Sector of the North sea is in discussion related to the need of sand for shoreface, beach and dune nourishment and large-scale engineering works at sea (Maasvlakte extension, airport at sea). The mining methods considered, basically fall into two categories: wide, shallow or small,...

During the second half of this century offshore sand extraction has become commonplace. There has been an important increase of sand demand to use on construction and coastal protection as well as for industrial purposes. On the other hand, the development in the dredging field has helped to the expansion of the process. Since nearshore dredging...

Large-scale, marine sand mining in front ofthe Dutch coast might be necessary in the near future in order to meet the needs of sand for regular engineering works and/or for a possible second Maasvlakte or a national airport on an artificial island. In order to make a socio-economically and environmentally sound decision with respect to location...

Tijdens de zandwinning op zee wordt er gebruik gemaakt van sleephopperzuigers. De sleephopperzuiger laat het overtollige proceswater overboord stromen. Het mengsel dat overboord stroomt wordt overvloeiverlies genoemd. Dit rapport geeft een beschrijving van de bevindingen van een literatuurstudie naar de verspreiding van het overvloeiverlies dat...

Zowel in het kader van de voorbereiding van de nota Kustverdediging als het Regionaal Ontgrondingenplan Noordzee wordt een grote behoefte aan Noordzeezand voorzien. Het betreft zand ten behoeve van erosiebestrijding van de kust (suppletiezand) en voor gebruik op land (vnl. ophoogzand) . volgens het huidige beleid wordt dit zand zeewaarts van de...
