Introduction
Graduated at the Cadi Ayyad University 1991, then jointly graduated from UCA and the Catholic University of Louvain (Belgium), with a Ph.D. thesis in hydrology, hydrogeology and hydrogeochemistry in 2002, I focused on areas of research related to climate variability and climate change and their impact on water resources in arid and semi-arid regions. Using several tools such as GIS, remote sensing, hydrological modeling of water and sediment flows, hydrogeological modeling, data processing and analysis, urban hydrogeology. I supervised a respectable number of doctoral theses, I participated in the evaluation of a very large number of PhD theses, I am reviewer in several scientific journals. I coordinated several research projects, at national and international levels.

Preliminary results of the contribution of Marrakech High Atlas watersheds to the Plioquaternary aquifer of the Haouz plain recharge. A primary hydrological study based on remote sensing technologies. The region of Marrakech in Morocco is in an arid to semi-arid climate. The amount of water available is low and varies in space and time. In addition...

Proper knowledge of potential groundwater recharge (PGR) and its spatiotemporal distribution are essential for sustainable groundwater management, especially within the context of climate change. Here, a robust GIS-based water budget framework was developed to estimate PGR at a regional scale and map its spatial distribution. This framework is demo...
Article
The Hydrological modelling in a semi-arid mountainous area is very challenging due to the irregular climate and the spatial variability of vegetation cover and topography. The hydrological model CEQUEAU was used with a daily time step on the arid and semi-arid mountainous region of the Ourika watershed. The capability of the model to simulate the d...

Water management has become one of the major interests in arid and semi-arid regions. Scientists have suggested different criteria and methodologies for the identification of suitable dam sites. According to our literature review, we have used two major methodologies for the selection of suitable dam site location: geographic information system and...

The quantitative monitoring of the shallow aquifer in Marrakesh and its surrounding area shows that the water table has been lowered gradually over the last 40 years, and attaining an acute decline in the early 2000s. This declining trend—if confirmed in the future—may lead to a water shortage, or even to a total aquifer depletion, which would be d...

This work is dedicated to the study of the spatio-temporal variability of climate in Morocco by the analysis of rainfall (gridded and gauged data) and runoff. The wavelet analysis method has been used in this study to compare the rainfall and runoff series and to show the major discontinuities identified in 1970, 1980, and 2000. Several modes of va...

This study evaluates the performance of the two satellite products: the Tropical Rainfall MeasuringMission (TRMM 3B43V7) Multi-satellite Precipitation Analysis (TMPA) and the Integrated Multi-satellite Retrievals for GPM (IMERG V06) (SPPs) to observed rainfall, at different time scales (daily,monthly, and annual) from 1 September 2000 to 31 August...
Article
The Haouz plain aquifer is one of the most important aquifers in Morocco. It is supporting so many activities tightly connected to the local and national socioeconomic development (agriculture, tourism, industry). The recurrent drought the region has been experiencing, had led to a major mobilization of groundwater to meet human needs and socioecon...
Article
Arid and semi-arid areas are often subject to sudden and flash floods, causing extended damages to the population and infrastructures. This paper presents a method for flood assessment in the Zat watershed (sub basin of the Tensift catchment) via 10-minute numerical modeling using the HEC-HMS numerical model. To illustrate the calibration and the v...

Conference Paper
Moroccan High Atlas regions are often subject to flash floods, and are constantly undergoing major human and material damage because of the heavy inundations. Flood damages will increase over the years due to population growth, the socio economic development and the climate change because of the global warming effect. That's why the modeling of the...

en Water resources are a priority for economic development, aiming at meeting the increasing needs of agriculture and all socio‐economic sectors. Agriculture is one of the essential pillars of this development in the Haouz Plain. Under a semi‐arid climate, irrigation, consuming more than 85% of available water, is inevitable for most crops. Hence,...

Article
Full-text available
Arid and semi-arid regions face multiple problems in terms of water management, particularly where surface water is a primary resource. On the northern flank of the High Atlas Mountains (Morocco), deforestation has resulted in soil erosion and siltation of reservoirs. Better characterization of sediment yield is important for reducing the impact of...

Arid to semi-arid regions are characterized by low levels of surface water and low annual precipitation (generally <350 mm/year). In such area, the Rheraya catchment (225km) located in the High Atlas Mountains of Morocco, south of Marrakech city, with altitudes ranging from 1084 to 4167 m. The objectives of this study set out a methodology that wil...
Conference Paper
Arid and semi-arid regions are often subject to flash floods. One of the most important tools for assessing flood intensity is the modeling of rain events. In the Tensift watershed, the frequency of past floods and their future predictions require a critical consideration of flood risk. In fact, the frequency of floods is increasing because of clim...

82-year rainfall timeseries have been studied together with climatic patterns of NAO using classical statistical methods. Then, the wavelet approach has been applied to show annual (1 year) and inter-annual (2-4y, 5-8y and 8-16y) modes distributed following four major discontinuities: 1945, 1960, 1975 and 1995. The 1y, 2-4y, and 5-8y powers show hi...
