The dynamic nature of rivers and its effect on the inhabitants and its surroundings is of fundamental concern to Hydro Scientists, Coastal Engineers, and Surveyors. These changes have remained unpredicted and hence the focus of this study. The aim of this study is to develop a geo-model of the dynamics of Orashi River in Ogba/ Egbema/ Ndoni Local Government Area of Rivers State. The objectives are to determine the river dynamics parameters, to develop a functional multiple regression model of Orashi River dynamics and to determine the percentage contributions of each of the independent variabl

Phenolic compounds are hazardous with diverse health implications. The presence of phenolic compounds in rivers is triggered by several activities including petroleum products. The Niger Delta is one of the world’s major hydrocarbon provinces with several health hazards created by oil exploration and exploitation and slow in action to oil spillages. Therefore this paper assessed phenolic compounds in surface waters from New Calabar River and Orashi River in the Niger Delta Region of Nigeria using GC/MS technique (Agilent 6890N Gas agilent 5975 mass selective Detector).

This study delineates morphometric parameters for determining flood influence on river catchments in the Niger Delta Region using geospatial techniques. Data from the United States Geological Survey; Shuttle radar topographic mission was processed using ArcGIS 10.6 software. The results of the hydrological data analysis, compound factors, and weighted overlay approach demonstrate that early peak flows from the River Niger cause flooding along the riverbanks, as evidenced by the stream frequency findings. The Ikoli River's catchments consistently provide the River Niger with its peak discharge

Flooding is one of the most frequent and widespread of all environmental hazards and of various types and sizes. This study investigated the flood vulnerability levels in the lower Orashi River, Niger Delta Region, Nigeria. The study considered the landuse, soil texture, elevation, slope, stream power index (SPI), rainfall, drainage density and proximity to river channels as factors determining flood. The components of these factors were reclassified as lowly, moderately and highly vulnerable areas with assigned numbers 1, 2 and 3 respectively. All the maps were overlaid using the UNION module

This article examines the rising food insecurity in the Orashi area, which comprises four local governments in Rivers State. From 2012 to 2022 there have been rising food shortages in the region as a result of many known factors such as climatic changes, rural insecurity, exchange rate and global food prices among others. Some works on food insecurity suggest factors like drought and diversification, but the food insecurity in the Orashi region area is caused mostly by natural forces and man-made actions of non-state security actors (cultists and militias) and activities of the royal fathers w

The length-weight relationship and condition factor of two hundred and seventy-one samples of Protopterus annectens (Owen, 1839) from Orashi and Sombreiro Rivers were investigated. The length-weight relationship calculated for the species gave an average “b” value of 1.0943 which is an indication of negative allometric growth. The fish attained an average length of 44.7 cm and weight of 150.2 g. The Condition factor varied from 0.10 to 0.19 with a mean of 0.15±0.02. This result showed that the rivers provide nourishable environment for the well-being of the fish.Keywords: Length-weight relatio

These strands of unique techniques are embedded in their indigenous knowledge as a people and revealed through the actions they display during such times of disaster.

Aspects of the biology of the African lungfish, Protopterus annectens (Owen, 1839) from Orashi and Sombreiro Rivers in Rivers State, Nigeria were investigated using routine biological approaches. Samples were collected between October 2012 and September 2013. The analysis of the stomach content showed that the fish from both rivers fed mainly on detritus, which accounted for 100% of the stomachs examined. Other food items included remains of higher plants, filamentous algae and diatoms. A sex ratio of 1:1 male: female was observed, although, females were more predominant than males during the

Climate change-related disasters have in recent years become a global phenomenon with catastrophic consequences. Africa has had most of the consequences of climate change related disasters, resulting in monumental urban and rural flooding, widespread casualties, displacements, loss of property and sources of livelihood. Given the long-term implications of climate change, it is critically important to understand how vulnerable communities respond to the menace occasioned by flooding. The impact of the flooding is felt more in low-lying communities situated along the coastal fringes leaving inhe

In urban areas, water is usually provided through piped systems from specific sources to consumers. Cities, towns, and peri-urban settlements typically benefit from piped systems, while rural areas rely on water supplies from surface sources like rivers and canals, as well as ground sources such as wells and tube wells. When traditional methods fail, alternative water supply systems emerge in both urban and rural areas. This paper addresses the question of whether alternative water supply arrangements are sustainable in terms of system reliability, consumer acceptance, cost-effectiveness, conv

In watershed hydrology, the morphometric features of a river basin are vital to examine the lower Orashi River basin morphological and hydrological aspects, as well as its flood potential, based on their morphometric characteristics using remotely sensed SRTM data that was analyzed with ArcGIS software. The areal, linear, and relief aspects of the Orashi River basin were examined as morphometric parameters. The lower Orashi river basin, according to the findings, has a total size of 625.61 km2 and a perimeter of 307.98 km, with a 5th order river network based on Strahler categorization and a d

The research was intended to study the influence of human and industrial activities on the Orashi River and two bony fish (Clarias gariepinus and Tilapia nilotica). Three groups are observed to have impacted the environment – Oil/gas industries, tyre burning from abattoir, untreated human and animal waste from settlers and the abattoir. The study was carried out from September 2019 to August 2020. The mean concentrations of the parameters studied in some samples were close to or exceeded World Health Organization (WHO) and Federal Ministry of Environment (FMEnv) recommended limits for drinking
