From Dobroudja Plateau, Romania 2020-12-04T04:01:32+08:00 Lucian Dinca dinka.lucian@gmail.com Emilia Vechiu dinka.lucian@gmail.com <p>Dobrudjea Plateau, located in south-east Romania, is characterized by low altitudes, old rocks, a temperate-continental climate and a silvosteppe and steppe vegetation. Pubescent oak is one of the tree species characteristic for this area. With average dimensions, this tree fulfils numerous ecosystem functions.</p> <p>The concept of “Climate-Smart Forestry – CSF” is recent and was adapted in this article for the pubescent oak characteristic for this area; clear and measurable criterions were also identified and applies for this species in order to identify the smart stands.</p> <p>Smart pubescent oak forests represent 3% of all this specie’s stands and are more common in the north part of Dobrudjea Plateau. They are characterized by advanced ages (61-70 years), 20%-30% compositions and even-aged structures. The forests are located on relatively small distances from forest roads, at altitudes of 100m - 250 m, and on west and east expositions.</p> <p>The present study has showed that smart pubescent oak forests can be established by taking into account 14 site (flora, soil or forest type) and stand conditions (pruning, vitality, average diameter and height, functional group and category, litter). The identification of these stands is extremely important for their protection as well as for applying the appropriate silvicultural measures.</p> 2020-10-30T00:00:00+08:00 ##submission.copyrightStatement## https://j.ideasspread.org/index.php/sdr/article/view/748 Comparative Study of Conventional Groundwater Quality Results with WQI Technique: A Case Study of Surjani Town, Karachi, Pakistan 2020-12-04T04:01:30+08:00 Adnan Khan adkhan@uok.edu.pk Aasma Khan adkhan@uok.edu.pk Bisma Naz adkhan@uok.edu.pk Rukhsar Rukhsar adkhan@uok.edu.pk <p>Present study is aimed to calculate the water quality index (WQI) of Surjani Town by using weighted arithmetic index method to assess its suitability for drinking purpose. For calculating WQI, 12 parameters (pH, TDS, EC, Hardness, Na, Ca, K, Mg, HCO<sub>3</sub>, SO<sub>4</sub>, NO<sub>3</sub> and Cl) have been taken into account. Except pH, all physicochemical parameters are exhibiting the maximum prominence in WQI quality rating scale (Qn) which suggests that groundwater is highly polluted. The computed value of water quality index (WQI= 331.62) is also found to be high which is comparable with enormously high concentrations of physicochemical parameters that are violating the WHO admissible limit for drinking purpose. Results revealed that the groundwater is under the influence of anthropogenic activity from nearby Jam Chakro solid waste dumping site. It is concluded that groundwater is highly deteriorated which is immensely inappropriate for drinking purpose according to WQI rating score.</p> 2020-11-19T00:00:00+08:00 ##submission.copyrightStatement##
