Abstract: Dams are structures built for controlling the flow of water for many useful purposes such as water supply, power generation, retention of mining and industrial waste, as well as recreation and flood control. However, they bring together some risk of dam body collapse causing damage for the dam downstream areas. Therefore, hypothetical dam break studies which provide mapping of areas potentially attainable in the event of a rupture are especially important for planning actions aiming minimization of associated losses. The aim of this research is to assess the degree of adherence or similarity between flood maps obtained by simulation studies and those effectively obtained from the collapse itself occurred in Dam I owned by Vale SA on January 25, 2019. The study focuses mainly on comparing the effects over the simulated flood maps caused by use of different representation of dam downstream topography relief, namely Shuttle Radar Topography Mission (SRTM), Advanced Land Observing Satellite from Alaska Satellite Facility (ALOS_ASF) and Airborne Laser Scanning (ALS) models. The simulations were performed using the HEC-RAS software developed by the US Army Corps of Engineers considering hypothesis of strong influence of relief in flood mapping results. In this way, three simulation tests were carried out for evaluation and discussion. In the first simulation, the digital terrain model derived from ALS was used. The second simulation was carried out associating the digital surface model ALOS_ASF with a spatial resolution of 12.5 m. Finally, the SRTM digital elevation model with 30 m spatial resolution provided by the United States Geological Survey (USGS) was used in third simulation. Results showed better adherence to simulations using data from ALS. This was verified by visual analysis over high resolution orthorectified images and by calculating statistics indicators such as the (F) index. Conclusions pointed out that flood patches resulting from simulation are critical tools for taking actions involving areas and populations to be affected, so the best relief model technologies like ALS data should be used in simulation.

Racism is a scourge which has plagued societies for centuries. Its root cause can be found in the fear of others. Some authors have considered it as a mental disorder in its more severe forms. We approach it from a novel and highly actionable angle by comparing it to a transmissible disease, candidiasis, with which racism holds many essential similarities that we outline in details. We also suggest various ways to eradicate and mitigate racism through practical action plans.

Oil and gas companies are facing an enormous challenge to create value from mature fields. Moreover, price volatility presents a massive impact on project uncertainties. Therefore, robust portfolio management is essential for oil and gas companies to manage critical challenges and uncertainties. The objective of this study is to develop a robust portfolio model to assist top management in oil and gas companies to drive investment strategy. PRIME (Pertamina Investment Management Engine) has been built to visualize advanced oil and gas project portfolio management. The engine observes the relationship between risk-and-return as the main framework drivers. The profitability index is endorsed as a parameter to envisage the investment effectiveness of individual projects. Correspondingly, the risk index is a manifestation of multi-variable analysis involving subsurface uncertainty and price. A nine clusters "tactical board" matrix is provided as the outcome of PRIME to define generic strategy & action plans. The PRIME analysis leads to a dual theme of perspective: both macro and micro-scale. The macro-scale discovers a diversification of strategy and scenario development to achieve long-term objectives. Whereas, micro-scale perspective generates a detailed action plan in a particular cluster as a representation of the short and mid-term corporate strategy. Several strategies and action plans have been recommended, including advanced technology implementation, new gas commercialization, additional incentives in the Production Sharing Contract, tax management renegotiation, and project portfolio rebalancing
