Geometries of surface and subsurface landforms and deposits in the Niger DeltaGeorge, Chinotu Franklin January 2014 (has links)
This research is focused on mapping the geometries of surface and subsurface landforms and their relationship in the Niger Delta. Landforms on the surface are studied to improve our understanding of the spatial distribution of buried landforms. GIS techniques are applied to high resolution Landsat and SPOT imagery to map surface landforms, a necessary step in order to improve and better constraint subsurface modelling. Also, attributes from three dimensional seismic data are used to map buried landforms. Both techniques are focused on mapping the spatial distribution of landforms and analysis of their shape, size, orientation, connectivity and density. Results on the study of fluvial channels, point bars, braid bars, tidal channels, beach-barrier islands and spits are presented in this thesis. The updated map of the subarial Niger Delta covers an area of 70,000 km2. Tidal channel width increases exponentially toward the coast; in contrast the fluvial channel width decreases linearly downstream. Tidal channels are interconnected within a complex network. The tidal channels are wider in the East and West Flanks while in the centre they are narrower. Here, channel mouths are at a high angle with the coastline because of a combined effect of high sediment flux and longshore drift. Tidal channels are therefore grouped into four distinct zones; the West (Forcados River Zone), the Central (Nun River Zone), the East (Sombreiro River Zone) and the Far-East (Cross River Zone) based on their channel morphology and density. Each lobe is influenced differently by the interaction of fluvial, tidal and wave-related processes. This implies that it is appropriate to look at the Niger Delta as an amalgam of deltas geographically separated into four lobes. The morphology of the beaches also supports the considered reclassification, as they show distinct morphologies within each of the four lobes. Beaches are longer and wider on the eastern and western flanks and thin out towards the central lobe due to high sediment influx and wave reworking. Parallel channels form between scrolls and ridges and are prominent in areas where tidal influence does not extend far into the land. The correlation between the geometries of the surface and subsurface landforms is very strong and indicates that where subsurface details are missing, it is acceptable and reasonable to use surface information to make predictions about the subsurface. The result will help in constraining parameters used in modelling of geometric and dimensional properties of reservoirs and to better manage uncertainties, all elements relevant to the oil and gas industry.

A method of designing resource inventories (soil-vegetation-landform maps) with user involvemenPottinger, Edmund Ladner January 1981 (has links)
This study tested a method of incorporating preferences of potential users in the design and presentation of a soil-vegetation-landform map and information retrieval system. The method utilized a questionnaire-interview program designed to elicit responses from potential user's. This test of the method tackled a small part of the whole problem by testing a small group of variables to enhance product utility.
All examples were based on a real resource inventory of a small watershed in the mountainous coastal rainforest region of B.C. The study looked at seven dependent variables: map scale, mapping unit symbol, mapping unit variables (differentiating criteria), interpretive (derivative) map legends, soil classification, interpretive map presentation and general map presentation. For each dependent variable a number of questions (based on real examples) were asked to see if there was a consensus of opinion. The dependent variables were compared with a variety of independent variables, such as job group, decision making level, education level, etc.
After a pilot questionnaire-interview program, all the identified potential users of the maps were sent questionnaires or interviewed. Tape recorded interviews using the questionnaire acted as a check on the effectiveness of the questionnaire. Combining questionnaires and interviews, there were 238 responses, which was roughly 80% of the established population.
The results showed that the method could work. A consensus opinion was obtained on map scale, mapping unit symbol, interpretive legends, soil
classification, interpretive map presentation and part of general map presentation. Interestingly, map producers tended to have significantly different views from the rest of the population. There were some variables for which no consensus was reached. There was either no consensus, or no real conclusions could be drawn due to poor question wording and poor examples.
A summary of the results, was sent to the interviewees to clarify some of the unanswered questions and have them ratify the results of the questionnaire-interview program. The summary was a substitute for a prototype map which would have been used in a real inventory situation. Results from the summary program generally indicated corroboration of the conclusions, although this summary technique was definitely considered inferior to a direct testing of the prototype map.
In conclusion, the method worked and could be incorporated in future inventories (future recommendations are included). It is an inexpensive and relatively simple procedure with which to test possible inventory, mapping and presentation techniques. The fact that this study indicated a significant difference between the desires and/or requirements of the map producers and the map users suggests a technique of this sort is certainly a necessity. It should also act as a very good user-producer relations and education tool. Introducing the maps to the potential users and having them involved in their design should improve information flow. / Land and Food Systems, Faculty of / Graduate
