4.0 JUSTIFICATION
The construction of drainage, canal and culvert in the country is given much of structural or engineering consideration with little or no environmental impact assessment of the operations after the design and construction. The environmental problem results from operation which are usually devastating.
Hence, this study significantly addresses the following issues.
• Identify the environmental hazards associated with the drainage, canal and culvert.
• Evaluate the magnitude or significance of the hazard and effect.
• Identify changes in downstream hydrology.
• Identify changes in downstream morphology caused by altering the flow pattern.
• Examine control techniques to eliminates or lesson the severity of the effect and to manage the hazards.
• Develops plan and procedures to manage the environmental changes due to the operation of the drainage, canal and culvert.
5.0 SCOPE OF THE STUDY
This project focus on the investigation into the causes of blocked drainage, canal and culvert; its effect and the possible control measure within Ilorin-west local government area in Ilorin.
The investigation covered the basic hazard which may be caused by blocked drainage, canal and culvert to the human environment and to look into the causes in the place it happens within Ilorin-west local government. Investigating the various control measure needed to bring blocked drainage, canal and culvert under control.
6.0 DESCRIPTION OF THE PROJECT AREA
Ilorin west is one of the sixteen (16) local government in Kwara state and also one of the five (5) local government that made up Kwara central popularly known as (Emirate) with its headquarters located/ situated in Wara Osin in Ilorin metropolis, this capital of Kwara state. A case study of Agbo-oba, oja-tuntun and Sawmill was assigned.
7.0 RESEARCH METHODOLOGY
The methodology employed are:- preliminary data source, which may include:-
A. RECONNAISSANCE SURVEYS
This is the feasibility study of the area to determine the Feeder Rivers, geology of the area and level of deterioration of building causes by flood as a result of blocked drainage, canal and culvert and also investigation into the cause of the blockage and also know the control measure to be used or adopted.
B. ORAL INTERVIEW
Oral interview was conducted to hear the view of the residents on the causes of blocked drainage, canal and culvert and to determine the control measure of the blocked drainage, canal and culvert in other to suggest the best control measures.
C. ADMINISTRATION OF QUESTIONNAIRE
Questionnaires was distributed for analysis

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 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---
