Abstract:

Tides play critical role in coastal processes, marine operations and navigation. Determination of tidal characteristics and prediction of water levels require knowledge of tide harmonic constants (amplitudes and phase lags) of all relevant tidal constituents. 37 days hourly water level observation was taken at established tide gauge station along Imo River and analysis of observed data using harmonic method implemented with T_Tide. 35 tidal constituents were generated and used for water level prediction. Tidal constants of four principal tidal constituents (K1, O1, M2 and S2) were used to comp

Abstract:

Akwa Ibom State is one of the six maritime states in Nigeria and has a shoreline of approximately 129km. Three important rivers (Cross, Imo and Kwa Ibo) transiting through some Nigerian states, terminally pass through the state before discharging into the Atlantic Ocean. Despite the extensive drainage systems and huge fisheries potentials of the state, very little is known about her role in the sustainable productivity of major fish populations. This study was undertaken to bridge information gap on fish type, migratory path and breeding sites of some fish fauna in order to protect fish popula

The objective of this research is to determine the actual source of organic matter in the Niger Delta Sea Shelf (NDSS). Organic carbon (OC) and n-alkanes were investigated in the suspended matter (SM) and surfcial sediments of the Niger and Imo Rivers and the opposite Niger Delta Sea Shelf. Organic nitrogen and carbon isotope (δ13C) values were determined as additional parameters in the sediments. OC and n-alkane concentrations were highly variable. This variability was interpreted as the result of sources of materials from the inland basins and a complex sedimentation pattern involving the di

Abstract:

Water can be a threat to public health when the chemical constituents or pollutants exceed certain standards or thresholds. To have safe drinking water, there is need for assessment of the water quality and regular monitoring. This study aimed to investigate the physicochemical and microbiological water quality of Nworie river, Imo State, Nigeria. Water samples were collected from two sampled points: upstream point 1 at Egbeada bridge and downstream point 2 at Umezurike hospital of Nworie river. The following Physicochemical parameters [Temperature, pH, DO, Colour, Turbidity, Total Dissolved S

Abstract:

A twelve-month study was conducted to examine the influence of physico-chemical parameters on the primary production of Nworie River to assess its suitability for fish culture. Water samples were collected from three stations along the river course and examined for various parameters. Data collected were analyzed using multivariate analysis, stepwise linear regression and spearman correlation while Tukey’s honestly significant difference was used to separate the means. Results showed that water temperature was significantly different (p<0.05) at all stations and were within normal range for

Abstract:

Igboland, also known as Southeastern Nigeria and some parts of South Nigeria, is the homeland of the Igbo people. It is a cultural and common linguistic region in southern Nigeria. Geographically, it is divided by the lower Niger River into two unequal sections – an eastern and a western section. The states captured in this area includes: Anambra, Enugu, Imo, Abia, Ebonyi, and minor parts of Delta, Benue and Rivers states. The Igbo culture and traditions are filled with many colourful ceremonies that distinguish them from the other tribes in Nigeria. Igba Nkwu Nwanyi is one of the many colourf

Abstract:

Purpose This paper aims to investigate the 28-day compressive strength of concrete produced with aggregates from different sources. Design/methodology/approach Coarse aggregates were crushed granite and natural local stones mined from Umunneochi, Lokpa and Uturu, Isuakwato, respectively, in Abia State, Nigeria. Fine aggregate (river sand) and another coarse aggregate (river stone) were dredged from Otammiri River in Owerri, Imo State, Nigeria. The nominal mix ratios were 1:1:2, 1:2:4 and 1:3:6, whereas the respective water–cement ratios were 0.45, 0.5, 0.55 and 0.6. Findings The compressive st

Abstract:

A fifty-seven (57) week investigation was carried out from September, 2019 to September, 2020 covering wet and dry seasons, to determine the fish fauna and its nomenclature in the Oguta Lake, Imo state, Niger Delta, eastern Nigeria. This research work was aimed at providing information on the fish stock and fish identification. During the assessment, fish samples were randomly collected from fishers twice weekly from five sampling stations along the River. The fishes collected were counted, and identified with identification keys. Species diversity and catches were analyzed using analysis of v

Abstract:

A study was carried out in Imo River Estuary, Akwa Ibom State of Nigeria to evaluate the perception of the local people on the environmental and socio-economic effects of timber harvesting and management. Five local government areas were purposively selected based on their proximity to the Imo River Estuary. Despite the high effect rates of timber exploitation, most of the locals of the study area have little or no knowledge of the severity of these effects on their environmental and socio-economic well-being; thereby, limiting the required rate and application of necessary mitigation measures

The composition and diversity of the fin fish of upper course of Otamiri River was study for the period of three months to evaluate the likely effects of the recent anthropogenic activities around the river on the fish species. Water sample for physcio-chemical parameter were collected and analyses using conventional field and standard laboratory techniques. Likewise, the fish samples were collected bi-weekly using active and passive fishing gear. All the physic-chemical parameters measured fall within the standard recommended limit for aquatic management except the pH, ammonia, total suspende
