Abstract:
A levee or dyke is defined as an earthen embankment extending. generally, parallel to the rivet channel and designed to protect the area behind it from overflow of flood waters. Embankments are the oldest known forms of flood protection works and. have been used extensively for this purpose. These serve to prevent inundation, when the. stream spills over its natural section, and safeguard lands, villages and other properties against damages.
Amoni village experiences tropical climate with both wet and dry seasons the village experiences a problem of water spilling over the natural section damaging lands, villages and other properties:
The main research objective was to design an 'embankment Levee 'on the River Malaba bank in Amoni Village and specific objectives. were to determine the topography of the project site, determine the type and physico-mechanical characteristics of the Soil at the project site, determine the key climate factors contributing to floods-and determine the cost-benefit analysis of the project.
The historical background, types, components and classification of Levee, the reasons which justify the need for Levee, water resources and evolution of irrigation in Uganda, design requirements for an embankment for flood control have been discussed in the literature review. Stability analysis of the embankment, dimensions of the channel by partial filling and partial cutting, design .and determination of the runoff flow rate are also discussed in the literature review,
The methods used in data collection during the research included; desk study, oral interviews, consultations and discussions; carrying out topographic surveys. Laboratory soil sample tests, and infiltration tests climatic data for 13 years for Tororo discharge and water level data. for 50 years from the current year of Rivet Malaba were obtained and Softwares like MS Excel were used in analysing the collected data, the embankment parts; berm width, crest width, top width and drainage blanket filters were designed using· the analysed data and appropriated materials were selected. Detailed drawings were generated using AutoCAD in two dimensions
