ABSTRACT : The work presented here focuses on the inter-annual variability of annual rainfall in Northern Algeria. This work is carried out by using the coefficient of variation (the ratio between the standard deviation and the average). We will try to show areas of low, medium and high variations in Northern Algeria. In order to do this, we use 333 rainfall stations spread over the entire study area, with a measurement period of 37 years (1968/2004). The contrast of rainfall spatial and temporal distribution has been demonstrated by studying the sixteen basins, as adopted by the National Agency of Water Resources. The high spatial variability characterizes the basins of the High Plateaus of Constantine and Chot El Hodna. Keywords: Northern Algeria - annual Rainfall - inter-annual variability - coefficient of variation RESUME : Nous présentons dans cet article une étude de la variabilité interannuelle des pluies annuelles en Algérie septentrionale. Ce travail a été réalisé en utilisant le coefficient de variation (le rapport entre l'écart-type et la moyenne). Nous essayerons de montrer les zones à faible, moyenne et forte variations dans le Nord de l'Algérie. Pour se faire, nous avons utilisé 333 postes pluviométriques réparties sur l'ensemble de la zone d'étude avec une période de mesure de 37 ans (1968/2004). -

Malheureusement le réseau hydrographique de l’Algérie n’est pas bien équipé par des stations hydrométriques ce qui engendre d’énormes problèmes pour la prédétermination et la prévision des débits d’étiages. Une analyse hydrologique détaillée de quelques cours d’eau équipés des stations hydrométriques nous a permis la prédétermination et la prévision des débits d’étiage. Sur la base de cette importante information, un modèle de prévision de débit d’étiage à été établi. Ce modèle permet le calcul de ces débits dans n’importe quel Oued non équipé de station de mesures en présence de Peu de données. -
Contribution a Une Analyse De La Dynamique De La Vegetation Des Parcours Steppiques Dans La Region De Biskra Au Sud-Est Algerien

Bazri Kamel-eddine, Docteur, MC. Ouahrani Ghania Université des frères Mentouri Constantine1/Faculté S.N.V, Algérie Abstract An ecological analysis is conducted in three sites (EL-Haouche, Zribet El-Oued and Khanguet Sidi Nadji) in a steppes halophytes in the Biskra region (south-east of Algeria). Our analysis shows that the degradation of this steppe and a regressive dynamic of vegetation is very important. The soil is completely stripped and covered with a whitish crust over large areas which results from the rise and deposition of salts on the surface, particularly in Khanguet Sidi Naji. The current situation of these courses is alarming; it requires a serious rational management. Keywords: Vegetation dynamics, halophytes steppe, Ecosystem, Degradation, Biskra, South-east of Algeria Résumé Un diagnostic écologique est réalisé dans trois zones pastorales à halophytes (EL Haouche, Zribet El Oued et Khanguet Sidi Nadji) dans la région de Biskra (sud-est algérien). Notre analyse montre une dynamique régressive et un stade de dégradation très avancée dans ces parcours steppiques, où le sol est totalement nu et couvert d’une croute blanchâtre sur de grandes superficies notamment à Khanguet Sidi Nadji, résultante de la remontée des sels. La situation actuelle de ces zones est alarmante ; elle nécessite une sérieuse gestion rationnelle.

PGS Newsletter http://www.pittsburghgeologicalsociety.org/ Vol. LXVII, No. 1 Robert Botterman, Editor September, 2014 Wednesday, September 17, 2014 The Pittsburgh Geological Society presents THE ROLE OF BASEMENT INFLUENCE ON CHANGING STRUCTURAL STYLES IN THE APPALACHIAN PLATEAU PROVINCE Craig A. Eckert EQT Production Co., Pittsburgh, PA Structural development of folds in the Appalachian plateau province can be shown to be directly or indirectly linked to the re-activation of pre-existing faults in the Precambrian. The majority of these faults can be linked to a fabric emplaced during Proterozoic tectonism associated with early collisional events responsible for the formation and eventual destruction of Rodinia and Pangea. Some folds are the result of a single phase of basement influenced contraction, while others are result of multiple phases of activity spanning multiple orogenies. A continuum of thick to thin skin tectonics is evident for the plateau and was affected by both the presence of salt and geometric relationship between Acadian depositional strike and predominant Iapetan fault orientation. Additionally, continual reactivation of basement faults controlled the distribution of Silurian evaporates, determined where fault initiation planes were to occur, established planes of weakness, and eventually aided in the amplification and development of the fold belts as they exist today throughout the plateau province. The influence of a developing foreland basin during Acadian time created sufficient dip on the surface of the Silurian decollement, allowing for a gravity sliding event preceding Alleghenian deformation. The importance of the Silurian incompetent units on overlying structural development increases northward into Pennsylvania where it reaches a maximum, then wanes northeastward as the depositional strike of the Acadian clastic wedge and the predominant trend of the Iapetan faults diverge. -
Assessment of Aquifer Mixing and Salinity Intrusion in the North-Western Sahara Aquifer System: a Hydrogeochemical Analysis- Algeria, Tunisia
Assessment of Aquifer Mixing and Salinity Intrusion in the North-Western Sahara Aquifer System: a Hydrogeochemical Analysis- Algeria, Tunisia By David F. Meyer B.S., Kansas State University, 2011 Submitted to the graduate degree program in the Department of Geology and Graduate Faculty of the University of Kansas in partial fulfillment of the requirements for the Degree of Master of Science Advisory Committee ________________________________ Randy Stotler (Chair) ________________________________ G.

L. Macpherson (Co-Chair) Date Approved: December 7, 2016 ii Abstract The North-Western Sahara Aquifer System is a complex multilayer leaky aquifer system providing water to Algeria, Tunisia, and Libya. Changing the hydrologic equilibrium through pumping can cause previously isolated saline water to mix with the fresh water in the pumped aquifers, resulting in increased salinity over time and, creating the potential for water-related conflict. The objective of this study is to identify areas where salinity intrusion is occurring now and could worsen in the future. To accomplish this, fourteen existing datasets were analyzed, yielding new insights into regional and local occurrences of salinity intrusion. Major ion chemistry and ratios of Br/Cl indicate that the source of salinity in the saline aquifers of the system, which intrude into the freshwater, is the dissolution of evaporates in the aquifer matrix. -
The Status of Soil Survey in Albania and Some of Its Major Environmental Findings
The Status of Soil Survey in Albania and some of its Major Environmental Findings Pandi Zdruli1 and Sherif Lushaj2 Introduction Over the last thirty years, a valuable experience has been accumulated in Albania, regarding soil survey and its applications. Initially it was the Soil Science Department of the Agricultural Univer- sity of Tirana who carried out soil activities, and then the Soil Science Institute (SSI) of Tirana, created in 1971 took the lead in all related ac- tivities. The latter is under the Ministry of Agri- culture and Food and it is the only one in the country specialised in soil science. Until the early 90s the Soil Science Institute, was very well organised, operating throughout the coun- try, by carrying out pedological surveys and fer- tility tests all over the agricultural land of Al- bania. Other activities included drainage and irri- gation research, soil microbiology, erosion con- trol, and topographic survey. There were 26 dis- tricts at the time in the country, each of them having their own soil laboratory and a specialised staff, among them one pedologist and one soil chem- ist. The Institute provided only scientific and technical guidelines for the “district soil of- fices”, since their management was handled by local administration. In twenty years period, detailed soil maps from 1: 10,000 to 1:50,000 scale, along with soil reports were prepared for each former agriculture co- 1 CIHEAM-Mediterranean Agronomic Institute of Bari. 2 Soil Science Institute, Instituti i Studimit të Tokave, Ti- rana, Albania. 69 Options Méditerranéennes, Série B, vol. 34 The Status of Soil Survey in Albania and some of its Major Environmental Findings operative, state farm and district. -

Being an important highquality date production region of Algeria, this area needs continuous monitoring of desertification indicators, hence highly exposed to climate- related risks. Given the limited access to field data, appropriate methods were assessed for the identification and change detection of salt-affected areas, involving image interpretation and automated classifications employing Landsat imagery, ancillary and multisource ground truth data. First, a visual photointerpretation study of the land cover and land use classes was undergone according to acknowledged methodologies. -
