Appraisal of A Detailed Perimeter Survey of Igwuruta Flood Plain In Greater Portharcourt City of Rivers State

Abstract

Perimeter survey is the establishment of perimeter points on the surface of the earth and taking bearings between lines or angles between the points, moreover measurement of distance to provide such points with defined coordinate values on a plane surface (X,Y) only. The aim of this work is to ascertain the dimension of Igwuruta flood plain in greater portharcourt city of rivers state.Below are the objectives to achieve the stated aim; to carve out an area of land. Selection of traverse station and marking of the selected station, demarcation of boundary points with bottle cork and nail, to establish boundary points of the study area, to determine the bearings and distances of survey boundaries, to generate the Easting and Northing coordinates of each points, ,to calculate the area of the portion of land, to fix reasonable details within the assigned site using any suitable method of detail fixing, to produce a digital plan of the site under study and to write a comprehensive report.The Perimeter and detail Survey was carried out at Igwuruta flood plain of greater portharcourt city of Rivers state.The survey was carried out in accordance with the third order specifications for a survey operation. The reconnaissance survey was properly carried out both in the office and on the field; this was carried out for proper planning of the survey operation by locating the controls needed for proper orientation, the instrument to be used, and selection of traverse stations and finally, drawing of a sketched diagram of the area under study.The data processing was done so as to reduce the data collected in the field and the necessary corrections were applied so as to obtain the corrected bearings and distances of points relative to one another.The corrected values were reckoned with in every aspect of computation and also in plotting the plan. The final plan was produced showing the boundary of the traverse, the bearings and distances and also the details found within the site. The plan was produced in digital format titled plan showing the perimeter and detail survey of the flood Igwuruta flood plain of greater portharcourt city of Rivers state. Finally, a comprehensive report was written on how the practical and field works were carried out.
