In order to avoid financial and human losses, the importance of flood forecasting seems inevitable. Considering that floods are caused by many natural and anthropogenic factors and also have limitations such as lack of complete information. In this study, artificial neural networks have been used as an efficient method for flood prediction. The neural network inputs include the Dubai River and the Eshel River, this data was collected over 8 Years from the Maroon River. The network used is a multilayer perceptron, also the neural network weights are optimized by the Gray wolf algorithm and the results are compared with other common methods. Analysis of the output results shows that the neural network with the Gray Wolf algorithm has better results than neural network and Genetic algorithms and the error of this method is 0.53%, which indicates high accuracy and precision for flood prediction compared to other evolutionary algorithms. This method is used to obtain the best amount of data for testing and training. As the results, the best rate is 80% for training and 20% for testing. Obtained results show the neural network error squares with 80% of the training data and 20% of the test data.","PeriodicalId":42850,"journal":{"name":"Present Environment and Sustainable Development","volume":null,"pages":null},"PeriodicalIF":0.7,"publicationDate":"2021-10-03","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"44334225","PeriodicalName":null,"FirstCategoryId":null,"ListUrlMain":null,"RegionNum":0,"RegionCategory":"","ArticlePicture":[],"TitleCN":null,"AbstractTextCN":null,"PMCID":"","EPubDate":null,"PubModel":null,"JCR":null,"JCRName":null,"Score":null,"Total":0}

The area of interest was scanned with the Leica Pegasus Backpack, a platform for capturing reality. With the help of the acquired data, a virtual tour of this village was made similar to Google Street View, but more complex due to the fact that LiDAR data were also purchased in addition to images during the scan, thus having the possibility to perform various measurements within virtual tour, made with Leica TruView and JetStream software. The inclusion of data in the virtual tour offers, in addition to measurable elements and the possibility of summative analysis of all components of physical space, from \"strengths\" to \"opportunities\" and \"risks\", data that are needed in the process of planning and sustainable development of space.","PeriodicalId":42850,"journal":{"name":"Present Environment and Sustainable Development","volume":null,"pages":null},"PeriodicalIF":0.7,"publicationDate":"2021-10-03","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"46897681","PeriodicalName":null,"FirstCategoryId":null,"ListUrlMain":null,"RegionNum":0,"RegionCategory":"","ArticlePicture":[],"TitleCN":null,"AbstractTextCN":null,"PMCID":"","EPubDate":null,"PubModel":null,"JCR":null,"JCRName":null,"Score":null,"Total":0}

Existing studies have explored the relationship between child mortality and water stress with different perspectives, however, the results vary due to differences in methods and context. There is still insufficient cross-country comparative research on the association between child mortality and water stress under the framework of SDGs. This article uses data of 20 developing countries to explore the association between child mortality and water stress, based on the path analysis methodology. The results show that in term of statistics, the level of water stress is negatively but insignificantly associated with child mortality in developing countries. This unconventional result is explained by a number of possible reasons such as high reliance on food importation in some developing countries, and also the indirect link between water stress and child mortality via a country’s socioeconomic development (measured by national poverty rate). The results enrich scientific knowledge of and provide practical implications to the interactions between SDGs.","PeriodicalId":42850,"journal":{"name":"Present Environment and Sustainable Development","volume":null,"pages":null},"PeriodicalIF":0.7,"publicationDate":"2021-06-30","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"44620514","PeriodicalName":null,"FirstCategoryId":null,"ListUrlMain":null,"RegionNum":0,"RegionCategory":"","ArticlePicture":[],"TitleCN":null,"AbstractTextCN":null,"PMCID":"","EPubDate":null,"PubModel":null,"JCR":null,"JCRName":null,"Score":null,"Total":0}

Sustainable development is a process that leads to the satisfaction of the current needs of people and at the same time goes towards further development without destroying and limiting the possibilities of meeting the needs of future generations. Therefore, joint efforts should be made as soon as possible to build a sustainable and safe future for all people and the planet as a whole. Therefore, it is important to promote and support sustainable development by managing natural resources and ecosystems and the entire environment including people. The presented research was done on-site in African and European countries (Egypt, Ethiopia, Guinea, Turkey, and Poland) to determine their level of sustainable development. The level of sustainable development was determined by selected indicators from the Human Development Index. The level of sustainable development was determined by selected indicators from the Human Development Index. In this study, the authors used basic methods of social and economic research as follows: (1) market observation, (2) primary research on-site and (3) secondary research and the use of statistical analysis (Pearson Correlation). These methods were used to define the social and scientific problems and identify factors that affected a country's sustainable development. The main scientific problem, addressed by the study was undertaken in order to help facilitate a outcome on the energy, food and agricultural sectors connected with climate change and environmental law. It was found that there is an extremely strong positive correlation (from 0.8 to 1.0), and a very strong negative correlation (from -0.8 to -1.0) between the levels of a country’s age share, CO2 emissions, renewable energy consumption, and natural resources depletion.","PeriodicalId":42850,"journal":{"name":"Present Environment and Sustainable Development","volume":null,"pages":null},"PeriodicalIF":0.7,"publicationDate":"2021-06-30","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"46279151","PeriodicalName":null,"FirstCategoryId":null,"ListUrlMain":null,"RegionNum":0,"RegionCategory":"","ArticlePicture":[],"TitleCN":null,"AbstractTextCN":null,"PMCID":"","EPubDate":null,"PubModel":null,"JCR":null,"JCRName":null,"Score":null,"Total":0}
