Index. décimale : 550 Sciences de la terre Résumé : This research project aims to apply the tools of geographic information systems (GIS) and remote sensing
techniques for the rational management of water systems located in the lower catchment basin of river of
Djendjen. This is the assessment of water resources and protection of these water systems against environmental
hazards: water pollution and soil erosion (silting of the future dam Tabellout). The region, is largely
mountainous, shows potential in water, consisting mainly of surface water. The groundwater resources
contained in the local rock (fractured aquifers and very small alluvial aquifers( are exploited in the sources or by
peasants well. The results show studied the basin has a very high erosive potential that exceeds the tolerable
threshold. The developed GIS has allowed us to consider several planning scenarios to reduce this type of
erosion and consequently lowering the rate of siltation dam. Among the proposed scenarios, the dense planting
system would appear as the most adequate.
With regard to water pollution, the approach applied allowed us to map this phenomenon by producing a series
of spatial and temporal environmental themes in the form of digital maps. This study shows that the majority of
water resources are threatened by pollution from multiple sources (agricultural, urban and natural). The
approach applied allowed to reclassify the study area according to a risk scale and according to the
administrative division, which gives the possibility to intervene independently on each municipality separately.
We conclude that this GIS is therefore an effective tool for planning, management, scenario proposals and
decision making, not only for the protection of water resources, but also for environmental management in
general.Diplôme : Doctorat En ligne : ../theses/sc-terre/AOU7023.pdf Format de la ressource électronique : Permalink : https://bu.umc.edu.dz/md/index.php?lvl=notice_display&id=10577 Apport de la télédétection et SIG dans la gestion des hydrosystèmes du sous bassin versant inférieur d’oued Djendjen (Jijel, Algérie Nord orientale) [texte imprimé] / Farid Aoulmit, Auteur ; Nabil Chabour, Directeur de thèse . - [S.l.] : جامعة الإخوة منتوري قسنطينة, 2016 . - 197 f. ; 30 cm.

BiologieTags : Variabilité Température Forêt NDVI SIG MODIS Est algérien Cartographie Variability Temperature Forest GIS , Eastern Algeria Cartography ???????? ??????? ?????? ???? ?????? ??????? ?????? ???? ????????? ???????? ????? ??????? MODIS ??? ??????? Index. décimale : 570 Sciences de la vie. Biologie Résumé : Algerian forest patrimony is estimated at 4 million hectares, including forests, Scrub and brush. This forest is exposed to natural and anthropogenic hazards that cause severe degradation resulting mainly in continued regressive evolution and a ubstantial loss of wealth. Among the natural threats is the climate conditions and particularly the temperature of the environment in which forest ecosystems evolve. In addition to its action on life processes, on growth and on phenology of species, temperature can change also the biogeographic areas of ecosystems.
In this study we analyzed the temperature to characterize the thermal environment of
eastern Algeria and the effects of its variation on the dynamics and photosynthetic activity of forest ecosystems in this vast area. The used data is the temperatures for a period of 30 consecutive years (1982-2011) and spectral index (NDVI) which can detect the photosynthetic signal above the canopy.
Statistical analysis of long temperature series reveals that the warming observed
worldwide is already noticed in eastern Algeria. The majority of the wilayas exposed to this hazard, where the trend is more pronounced for the annual maximum temperature, may reach 3 °C/30years, an increase of 0.1C°/year. Thus, the estimate of thermal field for each pixel in eastern Algeria was realized by using Geostatistical methods based on multiple regression between temperature and the explanatory variables describing the relief. From these spatial data, the thermal limits have been defined for each forest species. Finally, the technical of GIS and satellite images allowed us to monitor the dynamics of forest vegetation, and to build maps that define the relationship between forest biomass and thermal parameters. These maps helped us to
identify 901087 hectares where trees were very sensitive to changes in the average temperature, with a percentage of 53.9% of the total area of the studied forest ecosystems. Thus, the minimum temperature affects photosynthesis of forest species in an area of 852406 ha with 50.8% of the total forest area. This cartographic expression is effective, firstly for forestry in the discrimination of forest plots where the thermal factor is the limiting factor of productivity and secondly for decision makers to define the forest management strategies of country.

BiologieTags : Feux Forêts SIG Risque Télédétection fire forst GIS risk remet sensing ??????? ???? ????????? ????????? ????? ????????? ?? ??? Index. décimale : 570 Sciences de la vie. Biologie Résumé : This study examines the risk space of wildfires in the forest tracts of the province of El Tarf (North-East of Algeria). Wildfires have been a nation-wide concern for more than a decade now, and the various actions taken to prevent and suppress them did not result in a significant drop in their number or a decrease in the area of burnt land. Measures of punctual treatment of the visible symptoms of wildfires having reached their limits, this research aims at designing new forms of operational maps to be used for the management of forest lands in order to reduce the number and impact of wildfires. Earth observation satellite data associated with the different types of forest fire information, once integrated into a geographic information system, have proved to be a reliable option for monitoring emergencies, identifying areas at risk, and mapping the extent of the fires. The geographical database compiled in this work is an extremely useful tool for understanding and monitoring wildfires and will provide managers and decision takers with valid arguments to justify their decisions.

??????? ? ????? ????????Index. décimale : 621 Electronique Résumé : This work consists of a contribution to the modeling and the conception of dielectric resonator
antennas with application to the realization of reconfigurable antenna. The dielectric resonator
antennas are important antenna for the flexibility and the ease of integration in wireless
systems (WLAN), where they allow to use several shapes (rectangular, triangular,etc) and
several power supplies (coupling slot, coaxial cable,etc.). We are also interested by the
coupling effect due to the presence of another antenna or a presence of a coupling slot. The
calculated program based on the FDTD method to modeling a dielectric resonator antenna, we
enable to calculate the reflection coefficient, the input impedance electrical and the magnetic
fields. The HFSS simulator is used to validate these results. Then, this study has been
extended to the conception and the fabrication of a reconfigurable dielectric resonator
antenna. For this purpose, we studied and simulated a reconfigurable antenna structure by
using two simulator (HFSS, CST), then we proposed another structure which is a triangular
reconfigurable dielectric resonator antenna simulated by CST simulator and fabricated in RF
laboratory, of the National Institute of Scientific Research, INRS, Canada. The numerical
results are presented in terms of the reflection coefficient, radiation pattern, gain, and
efficiency. In addition, we have studied an dielectric resonator antenna with reconfigurable by
diodes PIN. Two distinct radiation patterns were obtained by maintaining the same resonance
frequency, which shows that the insertion of electrically-driven semiconductor components
into the antenna base structure provides an effective means for reconfigurability of the
radiation
