NON-LINEAR ANALYSIS OF SEEPAGE INTO DRAINS

ABSTRACTThe sustenance of viable agriculture depends strategically upon the provision of adequate subsurface drainage. The goals of providing adequate aeration and salinity control in irrigated lands have been translated into a number of criteria upon which drainage systems are designed. A brief ...

REGIONAL FLOOD-FREQUENCY ANALYSIS OF OGUN-OSHUN RIVER BASINS

ABSTRACTThis project describes a procedure for estimating the design floods from regional frequency curves for ungauged areas drained by rivers Ogun and Oshun of Western Nigeria. Streamflow records at nine gauging stations were used for the study. For estimating purposes, two relations have been ...

A COMPARATIVE EVALUATION OF THE FIXED ROUTE AND ROUTEDEVIATION STRATEGIES OF OPERATING INTRA-URBAU TRANSIT

ABSTRACTFixed route and route-deviation are among the possible strategies of operating intra-urban transit. The route-deviation strategy requires vehicles to follow a basic fixed route and deviate from the route to offer doorstep service to passengers on request. Thus a combination of fixed route...

RESIDUAL STRESSES IN ARC WELDED MILD STEEL BUTT JOINTS

ABSTRACTThis thesis is a study of residual stresses in arc welded butt joints and the effect of joint geometry and electrode type on the stresses. Three joint designs, the single- v, the double - v and square - butt joints have been considered. Two filler rods selected for this study are E6012 an...

COMPOSITE RISK MODELS OF OGEE TYPE SPILLWAY

ABSTRACTIn the existing design methods, consideration is given only on the stochastic process of flood flows imposed on the structure to account for hydrologic risk and the capacity of the structure is treated as deterministic. This thesis presents composite risk models which integrated hydrologi...

RELIABILITY-BASED DESIGN RULES FOR THIN-WALLED STRUCTURAL STEEL BEAM-COLUMN ELEMENTS

ABSTRACTThe sensitivity is compared giving recognition to the parameter, Qw, which represents the local buckling phenomenon. The design formulae are found sensitive to this parameter. Safety factors are applied either to loading or strength parameters in the two design equations studied. The vii ...

MINIMUM ECCENTRICITY IN THE ULTIMATE STRENGTH ANALYSIS

ABSTRACTThe nominal allowance for eccentricity due to construction tolerances as specified in three different codes of practice (ACI 318-77, CP 110, and CEB-FIP Model Code) was studied and compared with actual values of construction errors measured on building sites. It was found that the three s...

WASTEWATER IRRIGATION: SOME BACTERIAL AND HELMINTHOLOGICAL EFFECTS

ABSTRACTThe survival of faecal coliforms, faecal streptococci and of helminths in soil and crops irrigated with wastewater was studied between March and June in 1988. The results showed a more than 90% reduction in the counts of faecal streptococci by the 4th day and of faecal coliforms by the 6t...
