Empirical Model of a Vertisol Evaporation as Tool for Management of Soil Practicability using Portable Lysimetric Station under Arid Land Context
Provedor de dados: 111
Autores: El Aissaoui, Abdellah; Yassine, Almasmoudi.
Soil compaction caused by traffics is commonly considered as one of the major’s problems in agriculture. Moisture content have a significant effect on amplifying soil compaction. This study aims to approach evaporation trend of a vertisol (40.47% clay, 39.30% loam and 20.23% sand) having an organic matter content of 1.5% in order to manage timing of its plasticity as a determinant factor inducing compaction created by the traffic of machines. A portable lysimetric measurement system was developed to evaluate soil evaporation trend. An empirical soil evaporation model was developed using three measurement campaigns according to different temperature and irradiance behaviors. Soil moisture content was evaluated with two sensors using conductivity and...

Modeling Hydraulic Performance of a Drip Irrigation Network Directly Coupled to a Photovoltaic Pumping System
Provedor de dados: 111
Autores: El Aissaoui, Abdellah; Hajar, El Khalfi.
Drip irrigation network coupled to photovoltaic pumping system presents an alternative solution that can efficiently improves use of water and energy by small and medium irrigated farming systems compared to conventional energy use for water pumping. Standalone photovoltaic water pumping systems (PVWPS) coupled to drip irrigation network constitute the best technico-economical solution compared to PVWPS using electrical or water storage demanding additional cost for the storage device. However, the standalone PVWPS need adequate process control to optimally be coupled with a drip irrigation network as adaptation between variable irradiance inputs and hydraulic outputs are needed to overcome problem of emission uniformity instability that can affect the...

Performance study of a standalone direct pumping photovoltaic system used for drip irrigation
Provedor de dados: 111
Autores: HARKANI, ASSIA; El Aissaoui, Abdellah.
This paper aims to study performances of a standalone photovoltaic pumping system confronted to actual behaviour of incident irradiance. The system is based on a photovoltaic generator, a MPPT/ DC-DC converter, and a diaphragm DC motor pump connected to calibrated ( Flow versus Pressure) orifices, simulating small drip irrigation network, mounted in parallel scheme to vary the pump operating point according to timely varied irradiance. The result showed  that daily trend of solar irradiance influence considerably operating behaviour of the pump, consequently the performance of the standalone PV system is affected as there is inadequation between charges of the PV generator and the DC pump.  The hydraulic effeciency trends showed a dispersion and varying...
