Risk Analysis Van Sickle Island

Van Sickle Island, located in the Suisun Marsh in the San Francisco Bay Area, has experienced multiple levee breaches in the past. Due to the large social and economic implications of flooding, questions have arisen about whether the current management of the island is still feasible. This project, therefore, aimed to find the most financially...

Water Level Monitoring in the Karnali River, Nepal: Evaluating Satellite SAR Altimetry Techniques through Field Observations

Rivers play a crucial role in shaping landscapes and supporting ecosystems. This is demonstrated by the tiger habitats in and around Bardia National Park in West-Nepal, which rely on the Karnali River. This study contributes to a larger effort aimed at sustainably managing these tiger habitats. Monitoring the rivers in this remote area is...

Developing fieldwork experiments for water resources students of Hanoi University of Natural Resources and Environment, Vietnam

The study of water is without question an important one. We can learn a lot by studying the theory but in the end, it is essential to actually go out into the field and see the hydrological processes in practice for ourselves. The educational value of fieldwork lies not only in seeing theory become reality but also in experiencing the...

A study into arribadas at Playa del Ostional: A field investigation into the seasonal morphological and hydrodynamical differences of the nesting beach, the involved stakeholders and the key parameters influencing the occurrence of an arribada

Arribadas, a phenomenon of mass nesting behavior of sea turtles, attract millions of olive ridley turtles (Lepidochelys olivacea) to Playa del Ostional, a nesting beach in Costa Rica. The timing and size of these arribadas are influenced by various environmental factors, including temperature, tides, and moon phase [1]. The sea turtles are...

New method to measure dune erosion processes using a mobile, contained environment on a real beach

The Netherlands has 254 km of coastline that is covered with sandy dunes. As these dunes function as primary flood defences, intensive research has been conducted into dune erosion in recent years. This research mainly took place in laboratories, because all boundary conditions could be controlled and measurements could take place very...

Re-tracing the Senne: Making the invisible river in Brussels visible

Research about the covered river Senne in Brussels. This former river seems to be invisible, but this research shows that this former industrial river still lives in the city (within the architecture and the urban structure). What can a revitalization of this covered river mean? And how does architecture relate to this revitalized space?

Estimation of horizontal deformation rates based on tachymetric measurements: Processing measurements collected yearly in the geothermal area Bjarnarflag in North-East Iceland from 2015 to 2018

Measurements of a tachymetric network in the geothermal area of Bjarnarflag in North-East Iceland are performed during four consecutive years (2015-2018). For the yearly adjustment of the measurements an alternative iteration scheme to Baarda’s ’B-method of testing’ is proposed, because the level of significance of the F-test performed in the...

River-width determination by the use of optical remote sensing missions: A research based on the determination of sub-pixel accurate river-widths using optical remote sensing

River data on discharge and characteristics is essential for water management and water supply, as well as for flood prediction and flood control (Pan, Wang, and Xi 2016). In practice, many watersheds are ungauged due to high costs, inaccessibility and even due to political instability (Pan, Wang, and Xi 2016). For this reason, measuring...

Geological history and fracture network characterization in unconventional reservoirs of the McArthur Basin (NT Australia)

The geological history of the McArthur Basin (NT Australia) is poorly understood. It consists of five onshore Paleo- to Mesoproterozoic packages with mainly siliciclastic and carbonate rocks, with cumulative thicknesses up to 15km. The basin contains the world’s oldest hydrocarbons, principally hosted in unconventional...

Siltation Mitigation In A Data Poor Environment: Assessing The Influence Of A Sluice On Siltation Rates In The Nga Moe Yeik Creek, Yangon

The typically mild slopes of the muddy coastline in the south of Myanmar, enable the tide to propagate deep into the mainland, carrying muddy and saline water. The Nga Moe Yeik Creek (a tributary of the Yangon River) is closed off at the upstream end during the dry season and is subject to high siltation rates. Extensive dredging is necessary to...

Fieldwork coastal engineering: Varna, Bulgaria

One of these resort areas lies in the town of St. Konstantine I Elelna, where Hotel Sirius and hotel Azalea are built very close to the waterline. These hotels are dependent on their neighbouring beaches for the attraction of tourism and for the structural safety of their buildings. Therefore, they want an estimation of the erosion of the...

Fieldwork coastal engineering: Artificial islands Asparuhovo, Bulgaria

Sirius Beach and Azalea Beach are beaches situated north of Varna in Bulgaria. The beaches have names of hotels situated at the beach. The hotel owners describe large scale erosion at the beaches over the years. Throughout the years groups of students from Delft have measured the waterline (by GPS) and the cross sections. The beaches are...

Fieldwork coastal engineering, Varna, Bulgaria

On the first day research is done at a beach north of Varna, which is called Sirius Beach. This research is presented in chapter 2. In the research the waterline and cross sections are compared with the previous years. The following is concluded: there is a strong seasonal variation which influenced the measured data, there is a decreasing trend...

Fieldwork coastal engineering: Varna, Bulgaria

One week the students stay in the Bulgarian village St. Konstantin, near Varna, at the Black Sea. The main goal of the fieldwork is learn how to deal with problems occurring at data collection and the elaboration and interpretation of the collected data. Several coastal measurements are executed at a couple of beaches and their accompanying...

Fieldwork coastal engineering: Preliminary design of a floating marina, Varna, Bulgaria

The beach in front of the hotel Sirius is suffering from a retreating coastline. Bathymetry and beach profiles were measured. With the data from previous years the long term evolution of the coast was analyzed. The main conclusions were that the beach in front of the Sirius hotel is still suffering from erosion and if this erosion trend...

Fieldwork Coastal Engineering, Redesigning Cape Sirius, Varna, Bulgaria

This report is written for the course ‘Fieldwork Hydraulic Engineering’ held between the TU Delft and Sofia University. The course consisted of 19 participants who carried out measurements in and around the small village St Konstantin, near the Bulgarian city Varna, from the 29th of September till 6th of October. The report describes the results...
