Abstract:
Particle size distribution of some Afowo tar sands as well as mineralogical and bitumen saturation analyses were carried out with the aim of elucidating the sedimentological properties of the deposits. Fifty samples of tar sands of the Afowo Formation in parts of south western Nigeria were subjected to granulometric and petrological analyses to determine the particle size distribution as well as other textural characteristics. Three of the samples were analyzed for phase identification using Phillips PW 1050 diffractometer equipped with Cu X-ray source and operated at 40kV and 30Ma. The result

Abstract:
Nebkha plays a major role in the ecological and environmental stabilization by accumulating wind-blown sediments around shrubs. Grain-size characteristics of different positions on nebkha reflect the sorting effect of aeolian dynamics. Based on the collected sand grains of different positions on four types of nebkhas at the southern fringe of Taklimakan Desert, China, this paper provided detailed insight into variability of the grain size of surface sand on nebkhas. The results showed that: a) Grain-size distributions on shield-shaped Karelinia caspica Nebkhas under natural condition had the l

Grain size statistical parameters derived from Ajali Sandstone outcropping in Ayogwiri, Fugar and Orame in the Western Anambra Basin were used to determine the variation in current energy and sediment dispersal pattern. The sandstone was logged in the three locations: Ayogwiri, Fugar and Orame, and samples collected for grain size analysis. Statiscal parameters such as the mean, sorting and skewness were derived to enable the study. The average mean value for Ayogwiri is 4.29 (coarse silt), Fugar has an average of 3.63 (very fine sand) and Orame with an average of 3.78 (very fine sand). The va

Abstract:
Beach grain size plays a major role in controlling beach slope and sediment transport rates and is a crucial criterion in selecting the appropriate fill material for beach nourishment. Yet, little is known about how and why beach grain size (and sorting) varies both spatially and temporally on high-energy sandy beaches. Therefore, in this PhD research project, the presence, magnitude and predictability of any spatio-temporal sediment variability was investigated on a number of contrasting high-energy (average significant wave height = 0.8 to 3.5 m), predominantly macrotidal (MSR = 3.1 – 6.2 m)

Cross-shore bathymetric evolution in the nearshore zone often leads to threatening consequences such as beach erosion and shoreline retreat that concern the coastal community. A new, comprehensive cross-shore morphodynamic model was developed that can be used to describe and predict these phenomena. The study included both physical and numerical models that were designed to focus on the influence of sediment size characteristics on the cross-shore sediment transport process.

In the theoretical part there is described hydraulic roughness, velocity distribution in the case of hydraulically rough surface and the process of grain sorting in surface layer. The practical part of the thesis resolves the influence of surface layer on hydraulic roughness of bed, expressed by Nikuradse sand grain size ks. The results are formulas explaining dependence of ks on characteristic grain size dx from grain-size distribution curve and comparison with coefficient ks according to different authors.

Abstract Predicting the spatial distribution of rock properties is the key to a successful reservoir evaluation for hydrocarbon potential. However, a reservoir with a complex environmental setting (e.g. shallow marine) becomes more challenging to be characterized due to variations of clay, grain size, compaction, cementation, and other diagenetic effects. The assumption of increasing permeability value with an increase of porosity may not be always the case in such an environment.
