The Loukkos basin located in northern Morocco is characterized by developed agriculture and a significant water demand. needs are mainly satisfied from the Oued El Makhazine dam on River. This impacted silting up of its reservoir large amount not valued discharged into sea. aim this study to develop an approach secure supply promote optimal use resources, using decision-making tool RIBASIM. inc...

The condition of da'wah portraits in the current era information globalization which is increasingly heavy and complex certainly a challenge for development da'wah. emergence problems that target younger generation point threat to survival Muslims, especially Indonesia. This study aims look at portrait problem its strategy. type research used literature review. results obtained are faced become...

â â â  reports indicate that the mahabad dam has been silting up more than it was expected. this research has been tried to study the causes and the agents of these changes. a duration of two years periods (that is from october 1986 to october 1987 and october 1991 to october 1992) was taken up to compare and then to determine the role of the sedimentation on these changes. results show that th...

Inappropriate use and management of land has generated processes environmental degradation, in which the increasing removal forest coverage impaired hydrological cycle, water soil quality. The objective this work is to know effects protection spring, initial part its watercourse, on conditions a family property. study was carried out property located Rainha da Paz Community, Alegre-ES, using in...

Abstract The 2020 hydrological year is featured with the high-water level and high flow period far exceeding previous years. sediment deposition in flood season shallowed impeded channel. Based on analysis of 2020, impact catastrophic channel conditions upper shallow area Nangang, reasons for deterioration are analyzed. Meanwhile, maintenance countermeasures, necessity emergency dredging, speci...

This study aims to determine the condition of natural disasters such as floods and landslides efforts BPBD overcome them. The research was conducted in Pacitan City on basis consideration that are common this area. Data collected through open interviews, observation, document review, then data were analyzed descriptively qualitatively. results showed area consists mostly highlands form steep mo...

With the rapid development of construction and road engineering, accumulation silting waste soil is becoming more serious. In order to recycle silt, a new type stabilizer was developed in this study improve its mechanical properties applicability on roads. The optimal ratio components determined by orthogonal test grey correlation analysis. effects macroscopic silt were investigated unconfined ...

This paper presents the effects of actions aiming at tree planting, and thus protection land belonging to Ahmadu Bello University (ABU) in Zaria (Nigeria) from erosion. area is located within northern limits Guinea savanna belt, which has been considerably transformed primarily for agricultural purposes. For years this subjected destructive surface gully erosion processes, were documented both ...

Abstract The Oued Srou watershed located in the Middle Atlas Mountain of Morocco has been a subject serious soil erosion problems due to combination natural factors and anthropic activities. Therefore, hazard assessment mapping can be handy initiate remedial measures area. In this study, improved Erosion Potential Model (EPM) integrated with GIS remote sensing techniques is employed map assess ...

The sedimentation basin is an important part of hydraulic engineering. Because the prototype size too large and not easy to analyze, Mike 21 has advantages input, conversion, analysis, demonstration data results, which are flexible convenient; however, this method been used in engineering by previous researchers. This research Yellow River Diversion Project as object, a simulation model channel...
