The extreme rains of court duration are the principal cause of brutal and catastrophic flood that can be produced on a nombre of smal bassin on the french Alps. This study consists on a cartography of extraim values of pluviometric parametres, as a Gradex, rains with a period of 10 years, 100 years and 1000 years, for six steps of time (1 h, 2 h, 3 h, 6 h, 12 h, 24 h); and Montana parameter on the french Alps where the orographic effect is big and the estimation of reliables values on unmonitored site using data of environmental stations need the introduction of morphometric informations. The areA study covers a surface of 250 km × 450 km and dispose of 65 oluviometrics stations of average durations between 30 and 35 years. This study has been done on two steps, first we have done a presentation of a region by a relief and a climate, second, we have displayed pluviometrics systems using ACP method. The idea based on AURELHY method (Analysing Using Relief for HYdrometeology) that consists to intervene the local topography by a lineair regression and analysing by kriging the residu of the regression has been used for this cartography.
长时间的极端降雨是法国阿尔卑斯山上一个小盆地产生残酷和灾难性洪水的主要原因。本研究包括对降水测量参数的极值进行制图，如Gradex, 10年、100年和1000年的降雨，6步时间(1小时、2小时、3小时、6小时、12小时、24小时);地形效应较大的法国阿尔卑斯地区的蒙大拿州参数和利用环境站数据在非监测站点估计可靠值需要引入形态计量学信息。区域研究覆盖面积为250公里× 450公里，分布65个平均持续时间为30 ~ 35年的量测站。本研究分两步进行，首先，我们通过地形和气候对一个地区进行了展示，其次，我们使用ACP方法展示了降水计量系统。该制图采用了基于AURELHY方法(HYdrometeology analysis Using Relief)的思路，即通过线性回归对局部地形进行干预，并对回归的残差进行克里格分析。

The heavy metals enrichment and contamination are deliberated from twenty-four sediment samples collected along the Tamirabarani river and estuary. The concentration and spatial distribution of heavy metals in Tamirabarani River and estuary are analyzed for Copper, Nickel, Chromium, Lead, Zinc, Cadmium and Iron. The extent of pollution in these sediments was assessed using enrichment factor (EF), contamination factor (CF), geo-accumulation index (Igeo), Pollution Load Index (PLI). The contamination factor specify low to moderately contaminated, except for Cd. Igeo factors of all samples comprise strongly to extremely polluted index for Cd and moderately polluted index for Pb. The area PLI load for winter indicate higher variation than in summer, it is also noted that Pb and Cd are the major pollutants contributing high PLI values in the study area. This elevated value is mainly owing to the salinity intrusion and anthropogenic inputs. The constant variation of metals in sediment samples is due to the linking of industrial and anthropogenic influences. The combined and collective consequences go in front to a severe risk to the entire estuarine environment.

In recent years in particular, the detrimental impacts of dust storms around the world has become a matter of much concern. In this phenomenon, the movement of fine particles may fall into two categories of dry and wet depositions. It is a common practice to model dust deposition by a network of various resistances as it facilitates to characterize the impact of each mechanism on the overall rate of dry deposition. In this study, fewer assumptions are considered in comparison to previous models. The proposed model covers a wider range of conditions and also includes the impact of thermophoresis. Moreover, the complicated calculations of atmospheric stability and wind friction velocity are replaced with a simpler algorithm by using the meteorological data such as wind speed. The reliability of the modified deposition model is confirmed when compared with the available field data from the literature with good agreement both qualitatively and quantitatively.

Due to the collapse of some cemetery in Basateen area, South of Cairo, this paper presents the application of geoelectrical resistivity sounding and imaging, as well as ground penetrating radar techniques for outlining the reasons and the presence of draining water and groundwater at the investigated area. A Vertical Electrical Sounding (VES) survey was performed at 3 points through the studied site to investigate the vertical extent of the subsurface sequence and the saturation levels. A total of 9 Dipole-Dipole imaging profiles were surveyed to determine the lateral distribution of saturation of drain water and infiltrated groundwater, and a total of 6 GPR profiles with 100- and 200- MHz antennae were surveyed to evaluate and determine the depth and the degree of saturation of the subsurface layer/s. The qualitative and quantitative interpretation of the acquired VES's and dipole-dipole imaging profiles showing easily the levels of saturations at the studied site. From the interpretation of GPR profiles, it was possible to locate and determine the saturated zones and the level of the groundwater through the area. The radar signals are penetrated enough and enabled the identification of the subsurface reflectors. The results of GPR, VES's and Resistivity imaging showed a good agreement. The integrated interpretations were verified by local geology and information from several bores. Also, the study was supported by a chemical analysis from the drain water and Ein El-Seera spring (close to studied site), to determine the main source of the drain and infiltrated water at the studied site.

Forest conversion in agricultural land without considering the capability and suitability of land can causes a breakdown in Krueng Seulimum watershed. This breakdown can be seen by the high attrition, low productivity, high sedimentation in the upper land, and high fluctuation in the downstream. This study aims to predict the amount of erosion on any watershed land units and to manage of searching the right methods such as soil and water conservation techniques, which are able to suppress erosion.

Linke’s turbidity factors TL and perceptible water vapor in the atmosphere are essential for evaluating pollution trends in the area. The rise of TL is directly related to deforestation, industrialization, urbanization and influx of dusts and particulate matters from closer and far distance to the region. In this study, there is a computation of TL from three methods global solar radiation (GSR) data. These are model, ground and satellite recorded GSR. The model codes of mathematical equations in determining model GSR and TL were handled by MATLAB tool. The TL from model GSR were compared with ground and satellite GSR in terms of statistical evaluation indicators: The coefficient of determination (R2), root mean squared error (RMSE), Nash-Sutcliffe efficiency (E), its relative efficiency criteria (Er), index agreement (d) and its relative efficiency criteria (dr). All TLs from the model, ground and satellite GSR are approximately varied between 4 and 8. The rising levels have been approximately found in the range between 20% and 37.5% as compared to TL of tropical warm air (continental) since 1947. Atmospheric turbidity is an important procedure for early warning on monitoring air, water, soil quality for stability of healthy ecosystem.

Acute shortage of potable water on Ladoke Akintola University of Technology, Ogbomoso, Southwestern Nigeria has become a perennial problem over the years. In view of this, groundwater potential of the campus was investigated using geophysical methods. Ground Magnetic data were acquired at 10 m interval across the road network on the campus using the Proton Precession Magnetometer. Residualization process was carried out on the data using the Oasis Montaj 6.4.2 Software Package. Qualitative interpretation of the residual magnetic intensity map generated was used to categorize the campus into different geomagnetic anomaly zones. Seventy (70) Vertical Electrical Sounding (VES) data were also acquired and quantitatively interpreted. Geoelectric sections and isoresistivity of the weathered basement map of the campus were generated. Three (3) distinct geomagnetic zones which included basement high/ laterite (111 nT to 256 nT), intermediate magnetic intensity (-12 nT to 38 nT) and possibly basement depressions/ weathered basement (-279 nT to -89 nT) were delineated. The geoelectric sections revealed topsoil, laterite, weathered layer (aquifer) and the fresh basement respectively. The resistivities and thicknesses values of the layers were 170 Ωm to 2586 Ωm; 206 Ωm to 417 Ωm; 30 Ωm to 367 Ωm and 365 Ωm to ∞ and 0.3 m to 2.1 m; 3.0 m to 4.5 m and depth to rockhead of 0.3 m to 23.2 m. The groundwater potential of the campus was generally low due to high clay content of the aquifer.
