Abstract:

This article examines the geomorphometry of Ikpa River as a major determinant of the planning pattern for fluvial hazards in the Northeast of Akwa Ibom State. Geomorphometric parameters were computed for the entire area and the seven sub-basins sampled within the main watershed. A descriptive analysis of the parameters indicates that the dendritic Ikpa Watershed is a natural river with homogenous geologic formation and possesses high degree of integration of the smaller rivers. Sixteen geomorphometric parameters were measured for the seven sub-basins. Using Principal Component Analysis, four m

Abstract:

The study examined the hydraulic properties of the of IKPA river and and its impact on sediment transport. Measurements such as depths of the river, Top width, discharges were measured along the stretch of the river. The cross section of the river was divided with ranging poles with maximum distance of 4m apart. The maximum velocity of the river was 0.94m/s while the minimum velocity of 0m/s was recorded in the cross-section of the rivers. The maximum velocity of the river was recorded at the second vertical and the minimum velocity was recorded at the banks of the river and also on the bed of

This review synthesizes findings from 10 scientific publications utilizing the weighted arithmetic Water Quality Index (WQI) to assess the status of diverse water bodies (Ikpa River, Lower Enyong Creek, Nwaniba River, Imo River, Etim Ekpo River, Lower Qua Iboe River, Ibeno Estuary, Cross River, Ikot Ebak River and Oboroenyin River) all within the Cross River System. The Analysis reveals that 6 out of 10 sampled water bodies are moderately polluted, while the remaining 4 exhibit slight pollution levels. These findings underscore significant concerns regarding water quality degradation, predomin

Abstract:

This essay is an attempt to analyze Ikwa i ja [The Ikva River and Me], a poem by Jarosław Iwaszkiewicz (1894–1980). It was first published on 26 June 1927 in “Wiadomości Literackie” and then in the volume Return to Europe (1931). The poem was written during the re-burial of Juliusz Słowacki (1809–1849), when the poet’s remains were relocated from Paris to Krakow. Iwaszkiewicz participated in these celebrations. In the absence of a direct echo of these events, Ikwa i ja is not only an occasional poem. It can also be regarded as an attempt to verify the importance of Słowacki’s achievements and

Christopher Cabaldon is the mayor of West Sacramento, a small town just over the river from California’s capital city, Sacramento. Mayor Cabaldon received his Master of Public Policy and Administration (MPPA) in 1994 as part of the inaugural class of the program at California State University, Sacramento. He first became mayor of West Sacramento in 1998, and he was the first mayor directly elected by the citizens of West Sacramento in 2004.West Sacramento is growing rapidly. Since 2000, the population has increased by over 50 percent, nearly reaching 50,000 at the time of the 2010 US Census. C

The cut and thrust of this paper is the re-examination of an age long belief and practice among the Ika people of Delta State and the Obolo of Rivers State which is aimed at discouraging the practice of witchcraft and sorcery. The study critically evaluates the phenomenon which includes necromancy, divination and poison ordeal and concludes that caution is needed as the act which involves human life is not without imperfection. The discourse is comparative as it examines the methods of ascertaining death among the Ika and Obolo. It employs moral, social and philosophical springboards for the a

The ways of formation of Dubno volost are analysed with area square calculation on the separate stages of its development. Based on method of mapping settlements that folded the volost, the changes in its spatial limits and determination factors are characterized. The oldest documentarily confirmed possession of princes of Ostroh on Ikva river was district of Ivanyn. Fedir prince of Ostroh got patrimonial right on it in 1386.

Several machine learning techniques can be used to predict water quality in an area, one of which is through the prophet model approach which is able to provide fairly accurate predictions for the water quality index in Indonesia. The main objective of this research is to obtain a WQI prediction value as a baseline in the formulation of future environmental co

Abstract:

Traditionally, water quality is evaluated using expensive laboratory and statistical procedures, making real-time monitoring ineffective. Poor water quality requires a more practical and cost-effective solution. Water pollution has been a severe issue, hurting water quality in recent years. Therefore, it is crucial to create a model that forecasts water quality to control water pollution and inform consumers in the event of the detection of poor water quality. For effective water quality management, it is essential to accurately estimate the water quality class. Motivated by these consideratio

Abstract:

Sandy coasts are specific habitats of high ecological significance for many species of shorebirds. The Gulf of Catania, in the Eastern coast of Sicily, is considered one of the most important sandy coastal areas of the region for the wintering of different species of Charadriidae and Scolopacidae, also due to the presence of River Simeto’s mouth and other freshwater streams. Since the area has been subject to many changes in the last few decades and recent data were not available, a ten-year monitoring of the wintering shorebird community has been carried out, from January 2011 to January 2020

The syntaxonomic diversity of forest meadows at the Ob-Inya watershed was studied within the Novosibirsk Region. The territory is a part of the Sokur elevation, which approaches the Salair ridge in the south-east. Common is the erosion of the landscape reflected in dense network of river valleys and draws. The vegetation is transitional between subtaiga and forest steppe (Reverdatto, 1931; Vandakurova, 1957; Kuminova, 1973; etc.). Forest meadows (the order Carici macrourae–Crepidetalia sibiricae Ermakov et al. 1999 of the class Molinio-Arrhenatheretea R. Tx. 1937) occur on the edges and glades

The importance of wetlands as habitat and breeding grounds for waterfowls is recognized and has been extensively studied, but their role in regulating and maintaining ecosystems is less well documented. The use of wetlands by invasive species such as Common myna (Acridotheres tristis), considered as one of the 100 worst invasive species in the world, is largely unknown. Therefore, the Common mynas could have an influence on the occupation of native water bird species. The objectives of this study were to assess Common myna's (1) population size, (2) spatial occupation and (3) characteristics o
