In order to develop an urban GIS of Fez, we began with the scoping and feasibility study of the system. This strategic review has identified the characteristics of the urban areas, their problems, needs and existing potential, both in terms of data, equipment or personnel. This contribution focuses on a conceptual modeling of the geospatial database, the proposed template for the system and the quality assurance plan for the project. According to the feasibility study conducted during the first phase, the system must have an architecture respecting the intervention of actors in the city. Therefore, the implementation of the system requires an adequate hardware and software platform for optimum operation of the proposed urban GIS. After identifying technical choices, the financing plan of this scenario has been proposed. This arrangement is structured in three parts: Hardware, Software and Development/Training.

Hydrological Modeling of Upper OumErRabia Basin (Morocco), Comparative Study of the Event-Based and Continuous-Process HEC-HMS Model Methods

Human population growth and land-use changes raise demand and competition for water resources. The Upper OumErRabia River Basin is experiencing high rangeland and matorral conversion to irrigated agricultural land expansion. Given Morocco’s per capita water availability, River-basin hydrologic modelling could potentially bring together agricultural, water resources and conservation objectives. However, not everywhere have hydrological models considered events and continuous assessment of climatic data. In this study, HEC-HMS modelling approach is used to explore the event-based and continuous-process simulation of land-use and land cover change (LULCC) impact on water balance. The use of HEC-GeoHMS facilitated the digital data processing for coupling with the model. The basin’s physical characteristics and the hydro-climatic data helped to generate a geospatial database for HEC-HMS model. We analyzed baseline and future scenario changes for the 1980-2016 period using the SCS Curve-Number and the Soil Moisture Accounting (SMA) loss methods. SMA was coupled with the Hargreaves evapotranspiration method. Model calibration focused on reproducing observed basin runoff hydrograph. To evaluate the model performance for both calibration and validation, the Coefficient of determination (R2), Nash-Sutcliffe efficiency (NSE), Root Mean Square Error (RSR)
