Effect of solar radiation on the temperature of house walls facing the four cardinal points in the summer in Ouled Sidi Brahim (Algeria)
The current experimental study conducted in Ouled Sidi Brahim (Algeria) seeks to understand how the direction of the walls affects their temperature in the summer. A small red brick house of 20×20×20 cm 3 was used for the test, and throughout the experiment, the temperature was recorded every minute at the center of each wall facing the four cardinal points (East, West, North, and South) for 24 h (day and night). A digital acquisition device based on an Arduino board was realized to record the temperature on different days at the end of June, July, August, and the beginning of September. Only when solar radiation is present during the day can the influence of the walls' orientation be detected. The temperature of the walls remains nearly constant at night and drops from sunset to daybreak. The wall facing east is the hottest in the morning during the summer. The west-facing wall, on the other hand, is the coolest …

MULTIDIMENSIONAL ANALYSIS OF PRECIPITATION IN CENTRAL-NORTHERN REGION OF ALGERIA
The problems of water quality and quantity have the potential to affect users of the resource at the watershed scale. Watershed management is considered as an effective approach that brings together all water users around the core related issues in order to develop planned and concerted actions in a consensual manner to serve the general interest. In the central region of northern Algeria, there has been a severe and persistent drought in recent years due to a recurring problem, in time and space, of the availability of this resource. The spatial and temporal variability study remains one of the first tools of water resources manager. At the first stage, the study of spatial variability of the average monthly precipitation in central-northern Algeria, by a synthetic visualization of similarities between the response profiles of the seventy measuring stations, highlighted two rainfall gradients: a strong gradient between the northeastern and the southwestern regions of the study area, and a small gradient between regions of low and high altitudes. The link between the variables revealed three synthetic indicators; a big wet season where almost all precipitations are recorded, a short spring and a dry summer. At the second stage of this study, a temporal analysis of annual rainfall series recorded from 11 rain gauging stations, through trends, ruptures and the standardized precipitation index showed a trend towards precipitation decrease over the whole study area with an average of 20% over the observation period 1910-2010. The analysis of the standardized rainfall index shows that the drought that rages on this region of Algeria is a consequence of the rate of years with mildly dry which is 44% and that of severe dry represent 9%. The persistence and severity of the drought in recent years in the study area is reflected in the increase in the rates of years with mildly dry in the order of 13%, on one hand, and by decreasing year rates of the mildly wet of 12%, 4.5% for the moderate wet, 3% for the very wet and 5% for the extremely wet, on the other hand. Keywords: Spatiotemporal variability, precipitation, response profiles, variables links, dry, Algeria.

EVAPORATION FROM THE WATER SURFACE OF LAKES AND RESERVOIRS OF THE ARID ZONE OF THE MEDITERRANEAN: CASE OF ALGERIA
The value of water evaporation is a key data in establishing the water balance of lakes and reservoir dams. In general, the evaporation of water bodies is assessed either from observation data from evaporation pan (Colorado pan and class A pan), or by analogy with other reservoir dams for which these data are available. In frequent cases, the evaluation of the evaporation of water bodies becomes impossible by applying the two methods mentioned because of the reduced number of weather stations or the absence of evaporation pans among their equipment. Applying the analogy with other reservoir dams, it can lead to considerable errors. In order to eliminate the difficulty of determining the evaporation of water, often encountered by engineers and operators of reservoir dams, the development of a calculation method simulating the phenomenon of evaporation is essential. Keywords: Evaporation, water body, meteorological elements, Algeria.

Dynamique du transport solide dans le bassin versant de l'Oued Isser au droit du barrage de Koudiat Acerdoune (Nord Algérie)
Résumé – L'érosion et le transport solide sont des problèmes sérieux à l'échelle mondiale mais ils sont bien plus préoccupants dans certaines régions du monde, comme c'est le cas au Maghreb et plus particulièrement en Algérie. Les phénomènes de précipitation et d'écoulement sont des phénomènes complexes et sont impliqués directement dans les processus d'érosion hydrique et du transport solide. La présente étude a pour objectif de contrôler, critiquer et analyser les données de concentrations des sédiments en suspension mesurées au niveau de la station hydrométrique da La Traille. L'étude s'efforce de trouver et de mettre en évidence des relations régressives, entre les débits de la matière solide en suspension et les débits liquides, applicables dans le bassin versant de l'Oued Isser et susceptibles d'être appliquées à des régions (ou des bassins versants) situés en milieux telliens et semi-aride Nord Africains et soumises à des phénomènes similaires. L'optimisation des courbes de transport solide intra annuelles retenues, expliquant la plus grande partie de la variance, a été validée par la comparaison des valeurs estimées aux valeurs observées et par l'ajustement des résidus de la régression à la loi Normale. Les courbes corrigées ont été utilisées pour rectifier le biais dans les données logarithmiques transformées, notamment autour de la partie supérieure des débits élevés qui contribuent très fortement à la charge solide annuelle, et estimer la variation des bilans des apports solides (fins et grossiers) véhiculés par l'Oued Isser au niveau de la station hydrométrique de La Traille, durant la période (1970/71–1984/85), et déposés dans la retenue du barrage de Koudiat Acerdoune depuis sa mise en service en 2013. Elles ont permis également d'estimer la dégradation surfacique annuelle du bassin durant la période d'étude, qui est de l'ordre de 2142 t.km2.an1, au droit du barrage de Koudiat Acerdoune. Enfin, l'extrapolation des apports solides a permis de prédire l'envasement du barrage, le classer parmi ceux de moyen taux de comblement, de mesurer l'ampleur du phénomène d'érosion sol–transport solide–envasement du barrage et de proposer des actions pour y remédier. Mots clés : concentration / sédiments en suspension / courbes de transport solide / débit liquide / débit solide / dégradation spécifique / envasement / érosion / La Traille / méditerranée

ETUDE REGIONALE DES PLUIES MAXIMALES JOURNALIERES ANNUELLES FREQUENTIELLES DU CENTRE NORD D’ALGERIE
A real calamity for the design engineer of hydraulic structures when calculating annual daily maximum frequency precipitations, the north-central region of Algeria includes urban areas of great strategic importance such as Algiers (the capital). The estimation annual daily maximum frequency precipitations in this area from series of observations with little or no data, becomes unreliable. A regional frequency analysis emerged as one of the methods to resolve this problem. The L-moments method was applied to the annual daily maximum precipitations from fifty four rainfall stations in northern Algeria. This study permitted dividing this area into three statistically homogeneous regions. The Generalized Extreme Value (GEV) distribution and the Generalized Logistics (GLO) distribution were identified as the most appropriate regional distributions for modeling precipitation. In this study, they were used to calculate the regional quantiles for each region. For the above mentioned three regions, the values of roots mean square error between quantiles were below 8% for all return periods, an indication that the method used was appropriate. Keywords: annual maximum daily precipitations, regional frequency analysis, L-moments, Algeria.
