A Special Issue: Hydrological Behaviour in Small Basins Under Changing Conditions

Abstract: The present paper aim to overview on the Euromediterranean Network of Experimental and Representative Basins conference – ERB 2016. The 16th Biennial Conference ERB was held 5–8 September 2016 in Bucharest, Romania, and was hosted by National Institute of Hydrology and Water Management. The conference program focused on the theme “Hydrological behaviour in small basins under changing conditions”. The conference was followed by a field work on microscale hydrologic monitoring of water balance elements in Voinești Experimental Basin.
This special issues of Forum geografic/Geographical Phorum – Geographical studies and environment protection research (indexing in international databases) includes selected works – contained a variety of hydrology subjects – presented at the Euromediterranean Network of Experimental and Representative Basins conference. All published papers are assigned to Digital Object Identifier (DOI).

Geodiversity and geoheritage in Geography teaching for the purpose of improving students’ competencies in education for sustainable development

Abstract: Sustainable development has become one of the burning issues on a global, local and individual levels as a result of climate changes, pollution, rapid development and changes in the global information, economic, industrial and business sectors and value systems. In this sense, education for sustainable development, as part of lifelong learning, has become one of the most important strategic and educational policy issues in Serbia. The aim of this paper is to highlight the potential of geography as a school subject, with special reference to the role of the subject matter of geoheritage and geodiversity in education for sustainable development. The aim of pointing the benefits of integrated and out-of-classroom approaches in teaching geography, which favour an active, experiential and exploratory approach to learning about geodiversity and geoheritage, is that students can acquire competencies in sustainable development. As outcomes of geography classes, competencies also represent a basis for raising awareness and increasing accountability and responsibility in individuals for preserving geoheritage and geodiversity as part of the Serbian national treasure.

Geotechnical Properties of Some Soils in a Tar Sand Area of Southwestern Nigeria

Abstract: Engineering properties of some soil samples in Idiobilayo and Idiopopo areas of Southwestern Nigeria were studied with the aim of determining their geotechnical properties which can aid in the exploitation plan of the tar sands deposits in the area.
A total of six sampling locations with three samples each were established in the study area. Samples of soil both disturbed and undisturbed were obtained from the trial pits to a depth of about 1.5m at 0.5m vertical interval. The disturbed samples were subsequently subjected to classification tests such as grain size distribution and consistency limits using British standards 1377 procedure. However, the undisturbed samples were subjected to permeability test.
Results obtained in this study showed that the area of study is underlain essentially by sandy soils, with substantial silty content. Clay and gravel content are quite minimal. The particle size distribution curves confirmed a general dominance of silt to coarse-grained sand size particles in the soil matrix with minor but complimentary clayey and gravelly materials. Amounts of fines in the soils are less than 50% except in trial pts 4 and 5 where they are slightly above 50%.
The soils consist of sand (60.0 %) and silt (35.0 %). The percentage of fines (silt and clay sized fraction) in the soils was about 38.0 %, and makes the soils good base for landfill, since recommended percentage of fines, should not be less than 20.0 %. However the obtained values of permeability coefficient of 5.5 X 10-6 mm/s to 1.2 X 10-4 mm/s call for the lining of the base to avoid groundwater pollution by leachates.

Near surface thermal characteristics of alpine steep rockwalls in the Retezat Mountains

Abstract: The characteristics of the near surface thermal regime of two rockwalls with different aspect in the Retezat Mountains were investigated using two miniature thermistors. Three one-year (2012-2013; 2013-2014 and 2014-2015) rock surface temperature time series were available for the north facing rockwall, whereas only two seasons were analyzed for the south facing rockwall. The mean annual rock surface temperature (MARST) values were with 1.5-2°C colder on the northern rockwall compared with the southern steep bedrock face. Due to long daily exposure to sunshine, the south facing rockwall experienced more diurnal freeze-thaw cycles during the cold season compared to the north facing rockwall. Overall, the thermistor with a southern aspect recorded 40 and 55 more freeze-thaw cycles than the northern one. A greater number of effective freeze-thaw cycles were measured on the south facing rockwall. The maximum daily amplitude on the southern rockwall is three times higher than on the north-facing location (39.1°C compared to 13.6°C). Based on our findings it seems that the MARST values recorded on the shaded face of the steep bedrock suggest a quite likely absence of permafrost, whereas the MARST values at TPR indicate a quite certain absence of permafrost.

Changing dimensions of literacy scenario and their determinants in India: a geographical perspective

Abstract: The present study is attempted under four points. The first point discusses the regional trends and patterns of literacy rate by decades since 1951. The second examines the trends of literacy rate by inter-states and union territories in the study area during 1951-2011. The third observes the distribution pattern and male-female literacy differentials during 2011, while the fourth explains the factors which influence the literacy level in the study area. The study reveals that the total literacy of India increased from 18.33 per cent to 73.00 from 1951 to 2011. All the states showed positive growth in literacy rate, especially Kerala (93.91 per cent) and Mizoram (91.58 per cent) having the highest growth. The male (96.1 per cent) and female (92.1 per cent) literacy was found to be the highest in Kerala (96.1per cent). The present study concludes that lower gross enrolment ratio and high dropout rates are chief determinants of literacy in the study area. The study is based upon suitable statistical techniques to analyze the data. Finally, some suggestions have been given to enhance the level of literacy rate that may result into positive socio-cultural transformation.
