Risk indices and risk matrix have been used among governmental agencies for assessing risks and ranking alternatives protection measures. The popularity of risk matrices can be associated with its characteristics to quick assessing risk and providing inexpensive solutions. The risk assessment is associated with flood protection as: economic, environmental, and life-safety. Economic risks are reasonably well dealt with by the well-known traditional cost-benefit analysis, insurance, and financial markets. Environmental risks are difficult to assess by traditional methods in flood project evaluation. Environmental consequences cannot be directly measured, while social risks represent the most challenge to quantify. It may be possible to estimate the number of fatalities, and cost of damaged infrastructures, while the social aspects cannot be measured. This paper is proposing a flood risk matrix technique for assessing risks in urban arid and extreme arid regions demonstrated through case-study application on the catchment of Taibah University (TU) and Islamic University (IU) in Medina, KSA. The study focused on assessing the geographical impacts of the flash flood inundated depths for different frequencies from 5 to 100 years return periods leading to identification of the flood channels, and its floodplains that may be vulnerable to different degrees of flood hazards.

Mohammad Albishi, Jarbou Bahrawi and Amro Elfeki (2016). Derivation of the Unit Hydrograph of Allith Basin in the South West of Saudi Arabia. 7 International Conference on Water Resources and the Arid Environments (ICWRAE 7): 621-628 4-6 December 2016, Riyadh, Saudi Arabia. Abstract: Most studies on unit hydrograph theory is developed for temperate regions and to the best of the authors’ knowledge, there is no studies on this topic in arid regions because of the lack of runoff measurements. This paper presents the derivation of a unit hydrograph of a Allith basin and its S-curve in the south western part of Saudi Arabia to be used to predict flash flood more accurately in this region. The derivation is based on the method of stream flow data that has been collected from measured rainfall and runoff storms in the region. The study resulted in the unit hydrograph of 1 hr duration and the S-curve that is used to transfer the hydrograph to any other durations. This unit hydrograph can be used to predict flash floods in Allith basin and similar watersheds.

Transmission losses is caused by infiltration into the streambed in ephemeral streams. The conventional methods for flood routing in wadis is impossible to achieve due to transmission losses. The Muskingum routing procedure in its basic form has two parameters, the channel time lag, Km, and the weighting parameter, x. However, both parameters do not consider transmission losses of floods in channels. O’Donnell 1985 introduced a third parameter, α, in the continuity equation to allow for the lateral movement of floodwater. Elfeki et. Al (2014) carry some modifications of the assumptions such that the negative sign of the parameter α represents transmission losses. In this research, the third-parameter α has been investigated as a tool for estimation of transmission losses using data from Yiba catchment in the Kingdom of Saudi Arabia. A spreadsheet model will be developed to deduce the equations.

Sania Dzalbe is a PhD student in economic geography at Umeå University in Sweden who studies how people in rural areas adapt to crisis and adversity. Drawing from her upbringing in rural Latvia, she notes the importance of social reproduction in sustaining rural livelihoods, which often goes overlooked in traditional regional economic analysis. She argues that the concept of resilience is connected to the concept of loss, as during moments of crisis and major restructuring, societies lose not only jobs and industries but also the very mechanisms through which they shape their environment, both physically and socially. Current resilience studies in economic geography tend to disregard the role of social reproduction and the losses experienced by individuals by predominantly focusing on firms and economic production. However, to understand the evolution of rural regions and communities amid various challenges they face, one must recognize that social reproduction cannot be separated from economic and knowledge production processes.

May 2024. Water pollution, also known as marine pollution, is the contamination of water sources by substances that make it unusable for human activities and disrupt aquatic ecosystems. Major contributors of water pollution include industrial waste, agriculture and farming, accidental oil spills, sewage, and marine dumping. The effects of water pollution include severe health issues, economic disruption, and disrupting the food chain. Water pollution affects both surface and groundwater sources, with groundwater pollution causing unsafe use and surface water pollution affecting all water sources above ground. Types of water pollution include chemical, physical, and nutrient-rich fertilizers. Water pollution control, prevention, and mitigation strategies include effective wastewater treatment, stormwater management, soil and sediment erosion control, organic farming, biodegradable plastics, and water conservation.

LPlastic reuse stands as a pivotal strategy in the battle against environmental degradation. By giving plastic products a second chance, we significantly mitigate the burden on landfills and the natural world. This approach not only conserves resources but also diminishes the energy expended in the production of new plastics. Through creative reimagining and repurposing, we transform what might have been waste into valuable assets, from upcycled containers to innovative construction materials. Embracing plastic reuse not only reduces our reliance on virgin plastics but also fosters a culture of sustainability and resourcefulness, essential for building a more resilient and harmonious relationship with our planet.
