3.3.3 Secondary data
Secondary
data is the data that have been already collected by other researchers
and are readily available from other sources, for example, journals, and
internet. Secondary data is economical and time saving. It helps to
make primary data collection more specific, this is because the
researcher is able to identify the gaps and deficiencies and when
additional information need be collected (Kosso, 2011). It also assists
in understanding the problem as it provides a basis for comparison of
the data that is obtained from the field.
In the course of this
research, secondary data was extensively used. This data was obtained
from analysis of the relevant literature concerned with road
construction, road drainage construction, blocked hydraulic structure
and the design of the road drainage systems. The literature used in this
research therefore was extracted from Drainage books, journals,
research projects and the internet.
3.4 Data analysis and presentation techniques
Data
analysis is for the purpose of obtaining usable and useful information
irrespective of whether the data is qualitative or quantitative. The
research employed various statistical tools for the analyzing of the
data collected from the field. The data collected by the questionnaires
and observational forms were converted into numerical codes representing
measurement of variables using the statistical package for social
sciences (SPSS) for windows version vista and Microsoft excel.
Descriptive
statistics- frequency tables and charts were used in next chapter to
present a summary of the data by describing the type of data collected
and its frequency and occurrence. Plates were also used to clearly show
some of the information captured through photography. Descriptive
statistics was used because it enables meaningful description of scores
or measurements using few statistics. Quantitative and qualitative
statistics were then used to test the significance of the results on the
causes of blocked drainage, canal and culvert in Ilorin west local
government area.

ABSRACT - [ Total Page(s): 1 ]ABSTRACTDrainage is an essential component of road construction. In most designs of the road, the first thing to be put in place is drainage system. The presence of blockage in drainage system tends to reduce the carriage capacity of drainage and thereby affect life span of the road. The research employed a research survey in order to obtain the information that would describe the causes of blocked drainage, canal and culvert in Ilorin-west local government road and its effect on the surrounding ...

CHAPTER ONE - [ Total Page(s): 2 ]CHAPTER ONE1.0 INTRODUCTION Nigeria is the most populous country in Africa. At the census of November 1991, Nigeria had 88, 514,501 with an inhabitants and a population density of 95.8 per 59 km. The average annual growth rate between 1963 and 1991 is 1.7% (Baiye E; 1991). According to 2006 census figure, Nigeria had a population of 140 million people. The major hazard experienced in Nigeria includes flooding, erosion, deforestation, land degradation and climatic drought ... Continue reading---

CHAPTER FIVE - [ Total Page(s): 1 ]CHAPTER FIVE5.0 CONCLUSION AND RECOMMENDATION5.1 CONCLUSIONThe
level of awareness of waste collection services and waste management
regulations were relatively low in Abgo-oba, Oja-tuntun and Sawmil, the
percentage of those who use indiscriminate solid waste disposal methods
like open dumping, open burning and dumping in drainages, canal and
culvert were higher. Educational status, age, gender, cost of waste
collection services and the location of resident among others ... Continue reading---
