Abstract:

This article explores the dynamics of the relationship between Egypt and the countries in the Nile River Basin, with a specific focus on the natural challenges Ethiopia faces in developing water projects. This research employs a descriptive qualitative approach with the aim of identifying Ethiopia's natural conditions and their impact on water infrastructure development. Data sources include secondary literature from official reports, case studies, and statistical data related to Ethiopia's water resources and climate. Data were collected through literature reviews and document analysis. The r

Abstract:

Recent history has been marked by a shift from rural to urban living. Studies show that urbanization is most prevalent at coastal areas and river basins and these are the locations where most megacities are established. However, in the African context, there is a deficit of research in this area. The focus of studies in the ‘urban’ field show the expansion of cities towards waterbodies but with little or no attention to the implications of this expansion—‘the rural to urban shift’—particularly as they concern lakes as commons in a rapidly urbanizing world, such as African countries and the Glo

Abstract:

Hydrological design, planning and design of flood mitigation structures require detailed knowledge of the characteristics of the flood event, i.e. peaks, volumes, occurrence times and duration. In addition to the uncertainty associated with the occurrence in both space and time, these events may often have a correlation of varying strengths. The literature study interestingly reveals that the majority of studies are based on a univariate approach rather than a more realistic approach that recognizes the multivariate nature of the underlying phenomenology.

Abstract:

The sustainable development of water resources includes retaining some amount of the natural flow regime in water bodies to protect and maintain aquatic ecosystem health and the human livelihoods and wellbeing dependent upon them. Although assessment of environmental flows is now occurring globally, limited studies have been carried out in the Ethiopian highlands, especially studies to understand flow-ecological response relationships. This paper establishes a hydrological foundation of Gumara River from an ecological perspective. The data analysis followed three steps: first, determination of

Aim: Capillary microsampling of 15 μl whole blood from fingersticks or heelsticks was used to collect pharmacokinetic (PK) samples from pediatric subjects in two projects. Results: In a mebendazole multisite study in Ethiopia and Rwanda in subjects between 1 and 16 years old, complete PK profiles (7 timepoints) could be obtained, although some of the fingerstick samples were contaminated by the dosing formulation. In a multisite study with a respiratory syncytial virus drug in children between 1 and 24 months old, sparse PK sampling was done (2 samples). All samples were successfully analyzed

Abstract:

The period of high water flow from rivers is a complex phenomenon, which manifests itself in the form of large waters and floods. High flow periods are an important phase in the runoff of rivers, both by their extreme nature and by the effects they can produce on the components of the environment. The paper analyses several aspects related to the periods of water runoff from rivers: genetic factors, frequency, and temporal and spatial parameters of large waters and floods, case studies of the most representative floods, environmental, social and economic effects induced by floods.

Land degradation caused by improper land use management is a critical worldwide problem that has revived the issue of resources sustainability. Soil degradation, which involves physical, chemical, and biological degradation, is the key component of land degradation. Assessment of soil quality (SQ) indicators that distinguish soil degradation in different land use (LU) types is enviable to achieve sustainable land management strategies. The objective of this study was to assess the effects of land uses on soil quality indicators in the Geshy subcatchment of the Gojeb River Catchment, Omo-Gibe B

The main aim of this review is to explore the corporate social responsibility practices and stakeholders’ awareness about firms’ CSR in Ethiopia. The concept of Corporate Social Responsibility (CSR) came into existence to show the responsibilities that the business should take from the shoulders of the government and the NGOs particularly in developing nations. Since the living standard of the society is low in emerging economies, the CSR expected from business firm is much higher than it is used to be in advanced economy. Ethiopia is one of the least developed countries and thus, the involvem

Abstract Artificial rivers are one of the objects of cultural heritage that has not been studied, in both archaeology and its preservation. Preservation of artificial rivers is related to environmental issues, namely waste disposal in rivers, settlements on river banks, and flooding. Both studies are beneficial for the preservation of the artificial river. In this regard, this paper intended to gain the causes of unsustainability and its solutions. This paper uses a qualitative-descriptive method. The data were collected through field observations, interviews, and literature studies. The analy

Abstract:

Urban sources account for significant quantities of important diffuse pollutants, and urban watercourses are typically badly polluted. As well as toxic metals, hydrocarbons including PAHs, and suspended matter, priority urban pollutants include faecal pathogens and nutrients. Can urban watercourses be restored by sufficient reductions in pollution loads? Case studies in the UK and Sweden provide insights and some grounds for optimism. A major trans-Atlantic review of the performance of best management practices (BMPs) is informing BMP planning. New approaches such as the maximisation of self-p

Abstract:

Desilting basins play an important role in run-of-river hydro power projects on Himalayan Rivers. These rivers carry huge amount of sediment with them, due to steep slopes and fragile geology of the region. The suspended sediment enters through the power intake and ultimately the power house. This causes heavy damage to the turbines and other under water parts. Therefore, desilting basins are provided to eliminate suspended sediment from the water conductor system. The design of desilting basin is verified on a physical model for 90% removal of suspended sediment coarser than 0.2 or 0.3 mm and

Abstract. Throughout the world, wetlands are increasingly being recognised as important elements of the landscape because of their high biodiversity and goods and services they provide to mankind. After many decades of wetland destruction and conversion, large areas of wetlands are now protected under the International Convention on Wetlands (Ramsar) and regional or national legislation such as the European Union Habitats Directive. In many cases, there is a need to restore the ecological character of the wetland through appropriate water management. This paper provides examples of scientific

<strong>Runoff estimation in ungauged catchments is probably one of the most basic and oldest tasks of hydrologists. This long - standing issue has received increased attention recently due to the prediction in ungauged basin initiative by the International Associations of Hydrological Science. In developing countries like Ethiopia most of the Rivers are ungauged. Therefore,applying regionalization techniques for ungauged or poorly gauged river basin is crucial.
