Since 2014, we have witnessed an acceleration of the pace of massive relocation operations in Algerian cities, particularly in the capital, with the ambition of making the city of Algiers the first African capital without slums. This article presents an evaluation of the relocation operations carried out during the period from 2014 to 2016. The objective is to identify the socio-spatial impacts of massive relocation on the province of Algiers and the neighboring cities. For this purpose, we adopted a method based on the flow analysis of slum dwellers relocated with the data visualization technique, widely used in GIS. The results show that a large number of inhabitants were relocated in a relatively short time and that there was a random distribution of slum dwellers from the capital to communes within or outside its administrative boundaries, with negative impacts on socio-spatial transformations of Algiers.

The purpose of this study is to examine the residents' participation in the public operations for the rehabilitation of the built heritage carried out in the old town of Constantine. Constantine has undergone several intervention operations on its built heritage. However, few of them have been completed. This brings us to ask about the causes of these failures. Several hypotheses can be envisaged, including the predominance of private property, which represents 71% of the urban fabric, and the lack of effective participation of its residents. To confirm this, one case studies have been carried out: The pilot project for the rehabilitation of the street "Mellah Slimane" in 2005. The research followed a qualitative approach using several data collection instruments. The results of this work show several shortcomings in terms of the effectiveness of the participatory approach focusing on the residents during the studied operations. Understanding these limitations could help to rethink public action for heritage conservation in inhabited historic centres.

Floods, as one of the most frequent natural hazards, cause irreparable damage to infrastructure and agriculture, and housing every year. 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.

The purpose of this paper is to analyze the strategic and legal framework of the various areas directly dependent on the protection of biodiversity and the ecosystem approach in the funding programmes related to them. Data were collected by consulting a variety of sources, including articles, project results, European and national legislation, strategies and funding programs in the fields of Water, Forestry, Biodiversity, Climate Change, Fisheries and Aquaculture, Agriculture and Rural Development, Energy and Regional Development. The results showed that, in the areas analyzed, there are no efficient tools for the integration of ecosystem services and natural capital. The level of integration of the ecosystem approach in the analyzed areas compared to the state of ecosystems in Romania indicates that there are not enough measures to protect natural capital through sustainable management. Both inter-institutional integration and coordination are needed to streamline the management of natural capital and the correct analysis and implementation of a payment system for ecosystem services.

The phenomenon of hydrodynamic erosion affects the riverbeds in which sub-crossings of pipes or bridges are located. The depth of erosion is determined at a point in the riverbed by the use of specialized computational relationships. For some works located in the riverbed it is necessary to know the erosion depths on the perimeter of the flow section. The analysis models used to investigate the phenomenon of hydrodynamic erosion were: a - topographic model; b - calculation relations from the technical regulations; c - erosion simulation model on a river section. The obtained results were materialized by the evolution of the erosion depths on the considered river sector over an interval of about 5-15 years. The depth of erosion on the lower course of the Moldova River showed values from 0.75 m to 1.65 m on a research sector. The research results were capitalized on the design of the rehabilitation works of the constructions present in the riverbed.

The aim of the research was to create an "improved" virtual tour, which would allow the transformation of the image of a rural space into photorealistic virtual reality, through mobile scanning equipment and geomatic technique, to meet practical requirements: evaluation of the agricultural potential of the area, evaluation of the tourist potential, reconstruction of the urban space, territorial planning, etc, but also with theoretical implications in the scientific research in the field. 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.

The paper presents the result of research on simulating the flooding of a flood on a stretch of river located in an urban area. The study area was located on the section of the Trotuș River that crosses the city of Comănești, Bacău County. The simulation was performed with the HecRas program for several scenarios differentiated by the value of the transit flows (Q1%, Q2%, Q5% și Q10%,). In order to apply the simulation program, it was necessary to carry out complex studies such as topographic, hydrological, hydraulic, how to equip the river with regularization works, the constructive characteristics of the works, etc. The presence of the riverbed regularization works modifies locally flood parameters and implicitly the parameters of the flood band. The simulation highlighted the positive, but also negative, cooperation of the arranged and unarranged river sectors with regularization works for the formation of the flood band. Also, the simulation highlighted the need to rehabilitate the existing regularization works, but also the need to carry out new works.
本文介绍了城市河段洪水的模拟研究结果。研究区域位于穿过baccure县Comănești市的trotuuse河的一段。利用HecRas程序对不同交通流值(Q1%， Q2%， Q5% și Q10%，)的几种情况进行了模拟。为了应用模拟程序，需要进行地形、水文、水力学、河道整治工程、工程建设特点等方面的复杂研究。河床整治工程的存在改变了局部的洪水参数，也隐含地改变了洪水带的参数。模拟突出了排列和非排列的河段与规整工程的合作对洪水带形成的积极作用，但也有消极作用。此外，模拟还突出了修复现有正规工程的必要性，以及进行新工程的必要性。

Road transport, including accessibility and individual mobility is considered unanimously as a fundamental element of contemporary living. The study area is considering Braila County with a total population of around over 305,000. The area it is well served by 6 national roads, 27 county roads and 42 communal roads and contains some of the most heavily trafficked stretches of road in the Romania. The emissions analysed in this study CH4, CO, CO2, N2O, NH3, NOx, PM2.5 and PM10, were collected by the Agency for Environmental Protection Braila during 2015-2019 based on questionnaires according to EMEP/EEA air pollutant emission inventory guidebook. The highest level of pollutant emissions was recorded in 2017, more exactly 191714,5 Megatons. In this article we analysed five categories of pollution sources: Passenger car, Light commercial trucks, Heavy-duty vehicles, Motorcycles and Non - Road vehicles and other mobile equipment. With the exception of CO2, N2O and NH3, pollutant emissions decreased for the eight pollutants analysed.

Both child mortality and water stress are included into the Sustainable Development Goals (SDGs). 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.

Sustainable development is now a key factor in the global economy. 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.
