Investigating Effects of Pressure on Discharge Velocities of Different Sizes Fluid Jet
Abstract: This paper aims to investigate the effect of pressure on the discharge velocities of different sizes water jet. To fulfil the above aim, the study selected two different diameters such as 6 mm and 4.5 mm water jet which discharges water from variable water head, H. The measured and calculated discharge velocities for each water jet were determined based on travel time theory and flow equation respectively. In addition, an …

Mapping Flood Risk Using Sentinel -1 Data: A Case Study of Niamey, Niger
Abstract: Flood events are recognised to be one of the most among the most catastrophic disaster in the world, with a consequential loss of lives, goods and services. Factors such as rapid urbanisation, lack of proper infrastructure development, insufficient consideration of the environment and the effect of climate change have made floods even more destructive, particularly for developing countries that lack the means to respond appropriately during such events. The impacts …

Self-powered Portable Unit for Drinking Water Production
Abstract: The paper describes a new system to supply drinking water for human beverage requirements in natural disasters like earthquakes, volcano eruptions, flooding, hurricanes or typhoons. The system use solar energy to supply power to the drinking water production unit that operates using evaporation to obtain drinking water from dirty or polluted waters. The unit operates at low temperature thanks to the created vacuum, which reduces the evaporation point of water …

Analysis of Trend in Rainfall Data using Mann-Kendall Test and Linear Regression Method
Abstract: Rainfall is a vital part of the hydrologic cycle and changes in its pattern directly influence the water resources of concerned regions. Changes in rainfall response as a result of climate change that gives alarming to hydrologists and water resource managers as these changes in rainfall quantity and frequency are altering the pattern of stream flows and demands, spatial and temporal distribution of runoff, soil moisture, etc. The drastic changes …

Flood Control and Disaster Mitigation through Engineering Interventions for Economic Development in Nigeria
Abstract: Flood management and economic development are linked together in many aspects. As economic globalization and integration have developed over the past few decades, the relationships between the economy and national security have grown stronger. This paper discusses the relationship between sustainable development and disaster preparedness and management, as well as the roles of NGOs and the organizations, put in place to employ methodologies of open data principle and advanced techniques …
