Groundwater quality assessment of Dhanbad district, Jharkhand, India

Groundwater quality assessment is important to ensure sustainable safe use of water. However describing the overall water quality in the Dhanbad coal mining area of India is difficult due to the spatial variability of multiple contaminants and wide range of indicators that could be measured. An attempt has been made to study the spatial variation of groundwater quality based on an integrated analysis of physico-chemical parameters and use of Geographic Information System (GIS). Using GIS contouring methods with Arcview 3.2a, spatial distribution maps of Hardness, pH, TDS, HCO₃, SO₄, NO₃, Ca, Mg, Cl, and F have been created. From the Water Quality Index map it is inferred that despite the mining and heavy industry, the quality of water is predominantly good to excellent.     

北京市延庆区石窑村南地沟泥石流特征及发展趋势预测

本文以北京市延庆区石窑村南地沟泥石流为研究对象,通过野外调查与GIS统计分析,研究该流域降雨条件、地形地貌和沟道条件、物源条件等形成条件特征,针对流域内松散堆积物转换,开展了流域分区特征分析;通过14个因子分析,建立了该泥石流的发育阶段识别模型,对其发展趋势进行了预测;利用单沟泥石流堆积区公式开展了最大危险区预测研究,提出相应的防治措施建议。研究表明:石窑村南地沟泥石流内松散堆积物动储量达18.36×10~4 m~3,物源类型划分为冲洪积物源、残坡积物源、人工堆积物源和崩滑塌物源4种,其中残坡积所占比重最大。该泥石流属于暴雨-沟谷型-支沟群发型、中易发泥石流,泥石流发展阶段处于发育期,最大危险区面积为0.413 km~2,对沟口堆积区的石窑村及村民的生命财产安全造成威胁,建议采用局部物源平整与疏理排导渠相结合的综合治理措施。本文为该区地质灾害防治提供基础依据。

Fluoride in irrigation waters of Agra district, Uttar Pradesh

Underground waters of the semi-arid tract of Agra were examined for their F concentration and other chemical constituents. The F concentration in waters varied from 0.2 to 3.2 mg l⁻¹ and 56% of the waters contained injurious concentration of F for drinking water. However, these waters were not harmful for most crops with respect to F concentration. Fluoride concentration was not correlated with EC, B and Na concentration of groundwaters.     

Water quality trends in the Tarkwa gold-mining district,Ghana

A detailed hydrochemical investigation has been undertaken to establish whether mining has adversely affected streams in the Tarkwa gold-mining district and, if so, to what extent. The results show that streams that pass through mining areas and receive mine water exhibit significant spatial and temporal variations in their major ion hydrochemistry. Water analyses of perceived pristine areas reveal that the study area has undergone silicate weathering, but in mining areas, carbonate weathering was inferred. The inconsistency is attributed to the chemistry of mine waters discharging into receiving streams. This is supported by the average pH values of 6.48 for pristine streams and 7.74 for those affected by mine water. Trace element analysis did not show significant changes from the norm except for discharges from a spoil heap, which exhibited hydrochemical characteristics consistent with acid mine drainage. Saturation indices determined for the water samples reflect the sandstone–quartzite–phyllite lithology and intense weathering regime of the area as a result of the humid tropical climate.     

Hydrogeological studies on the Tarkwa gold mining district,Ghana

The physical hydrogeology of the Tarkwa area has been evaluated with a view to improving the understanding of its groundwater characteristics. It has been inferred that aquifers in the Tarkwa area possess dual and variable porosity and heterogeneous permeability with predominantly limited storage properties. Both soil infiltration and pumping tests have shown that the Banket Series has the best hydraulic features, but the Banket rocks are host rocks for gold. The effect of mining on the groundwater regime is discussed, comparing groundwater recharge estimates obtained using the water balance method (299±72 mm year⁻¹) and the stream hydrograph method (192±30 mm year⁻¹).

The effect of proposed district centres on Melbourne's central business district

Abstract

Concerns have been expressed that the designation of the 14 district centres in the MMBW's proposed Amendment 150 will have an adverse effect on the Central Business District. This paper analyses these claims and contends that there is little threat from the district centres themselves. Because the planning concepts espoused in Amendment 150 and the Melbourne LDS are not sufficiently related to the economic development processes occurring in the city, they will have limited success in other than physical enhancement terms. The opportunity to develop an alternative economic role for the CBD has been overlooked.     

兰州市红古区窑街20050906滑坡形成机理分析

兰州市红古区窑街地区地质构造条件复杂,人类工程活动强烈,地质灾害强烈发育。本文在野外地质调查、勘察和室内测试分析的基础上,对窑街20050906滑坡的形成机理进行了分析,滑坡区岩土体组成复杂,岩体风化卸荷严重,地表黄土中发育有陷穴和落水洞,下伏易风化泥页岩,岩层倾向与坡向一致,综合分析认为该滑坡在成因上属于黄土—基岩顺层滑坡,平面上分级分块特征明显。本文分析了多种工况条件下滑坡滑动前斜坡体的稳定性,在天然状态下斜坡体较稳定,在降雨、坡体堆载和坡脚开挖等因素影响下斜坡体发生滑动,并计算了各影响因素的影响权重。本文的研究方法和思路对于今后的类似地区滑坡的成因分析具有一定的指导意义。
