TRANSCRIPT
What is A Project???
� A Project is a temporary attempt (effort) undertaken to accomplish unique purpose
- characteristics of projects
– Unique purpose
– Temporary
– Require resources often from various areas – Require resources often from various areas
– Should have a primary sponsor and/or customer
– Involve uncertainty
• Applies to products and Services
• Depends on other projects and organization operation
• Exist within a Hierarchy - Program, Project, Task, Work Package, Work Unit
- Is full of Conflict - With Functional Group, with other Projects, within Projects
Project Phases and the Project Life Cycle
� A Project life cycle is a collection of project phases
� Project phases vary by project or industry, but some general phases include concept, development, implementation and support
� Products also have life cycles � Products also have life cycles
� The System Development Life Cycle (SDLC) : is a framework for describing the phases involved in developing and maintaining information systems
� Typical SDLC phases include planning, analysis, design, implementation, and support

Academic Model Managerial Actions
Phase 1 Conception– Determine that a project is needed
– Establish objectives
– Estimate the resources that the organization is willing to commit
– Sell the organization on the need for a project organization
Make key personnel– Make key personnel
Phase 2 Definition /Planning– Define the project organization approach
– Define the project targets
– Prepare schedule for the execution phase
– Define and allocate tasks and resources
– Build the project team
Academic Model Managerial Actions
Phase 3 Execution� Perform the work of the project (i.e., design, construction,
production, site activation, testing, delivery, etc)
Phase 4 Operation / Termination
• Assist in the transfer of the project product
• Transfer human and non human resources to other
organizations
• Transfer or complete commitments
• Terminate the project
• Reward personnel
Appropriate Models of Project Life Cycles
(EC, 2004)
• This cycle highlights three main principles:
1. Decision making and procedures are defined at each phase;
2. The phases in the cycle are progressive – each phase should be
completed for the next to be tackled; and
3. Programming and project identification draws the results of
monitoring and evaluation as part of a structured process of
feedback and institutional learning.
Practical Model, EC
Phase 1 Programming
• The situation at national and sector level is analyzed to identify problems, constraints and opportunities.
• This involves a review of socio-economic indicators, and of national and donor priorities. national and donor priorities.
• The purpose is to identify the main objectives and sector priorities, and thus to identify programs and projects.
Practical Model, EC
Phase 2 Identification
• identify project ideas that are consistent with
partner and donor priorities;
• assess the relevance and likely feasibility of these project ideas;• assess the relevance and likely feasibility of these project ideas;
• prepare a Financing Proposal; and
• prepare a financing decision for a Program of
projects.
Practical Model, EC
Phase 3 Formulation
• Confirm the relevance and feasibility of the project idea
• Prepare a detailed project design, including the
management arrangements, financing plan, cost-benefit
analysis, risk management, monitoring, evaluation and audit;
and
• Prepare a Financing Proposal and a financing decision.
Practical Model, EC
Phase 4: Implementation
• Deliver the results/outputs, achieve the purpose/objective and
contribute effectively to the overall objective/goal of the project;
Manage the available resources efficiently; and• Manage the available resources efficiently; and
• Monitoring and reporting
Practical Model, EC
Phase 5: Evaluation & Audit
A. Evaluation
– make an “assessment, of an ongoing or completed project,
program or policy, its design, implementation and results.
– determine the relevance and fulfillment of objectives,
developmental efficiency, effectiveness, impact and
sustainability.
– provide information that is credible and useful, enabling the
incorporation of lessons learned into the decision-making
process of both recipients and donors”.
Practical Model, EC
Principles of evaluation are:
– independence of the evaluation process from the programming and implementation functions;
– Credibility, through use of appropriately skilled and independent experts and the transparency of the evaluation process, including wide dissemination of results;including wide dissemination of results;
– Participation of stakeholders, to ensure different perspectives and views are taken into account; and
– Usefulness of the evaluation findings and recommendations, through timely presentation
of relevant, clear and concise information to decision makers.
Practical Model, EC
B. Audit
The purpose of an audit is to:
• Assess an activity/subject that is the
responsibility of another party against identified suitable
criteria, and
• express a conclusion (i.e. opinion) that provides the intended • express a conclusion (i.e. opinion) that provides the intended
user with a level of assurance about the activity/subject being
audited.
Practical Model, EC
The auditor expresses a conclusion on:
• The legality and regularity of project expenditure and income
i.e. compliance with regulations; and/or
• Whether project funds have been used efficiently and
economically i.e. in accordance with sound financial economically i.e. in accordance with sound financial
management; and /or
• Whether project funds have been used effectively i.e. for
purposes intended.
Water Resources Assessment
• Main Resources
– Surface water
– Groundwater
– Unconventional
• Tools
– Flood routing/delineation models
– Runoff models
– GIS
– Finite element
– Finite difference
– Lumped parameters models
Surface Water
• General Equation
I(t) – O(t) = ΔS/Δt
• O Inputs• Oin Inputs
– Precipitation
– Base flow
• Oin Outputs
– E/ET
– Infiltration
– Intakes
Qin

System Boundaries
• Reservoir
– Balance
ΔS/Δt=(P*Ares+Qin)-(E*Ares+Qout)
– Residence Time– Residence Time
S/I(t)
• Watershed
ΔS/Δt=(P*A)-(ET*A+Qout)
Groundwater
• Definitions– Saturated Zone: VWater=Vvoids
– Unsaturated Zone: VWater < Vvoids
– Moisture Content: VWater < Vtotal
– Voids/Pores: allow the flow of water– Water Table: surface where the water pressure in the pores – Water Table: surface where the water pressure in the pores
equals Zero– Porosity: n = Vvoids / Vtotal (~0 - 0.7)– Hydraulic conductivity [L/T]= represents how easily water can
flow through formation• Gravel >50 m/day• Course Sand: K = 30-50 m/day• Fine sand: K = 10-30 m/day• Silt: K = 1-10 m/day• Clay: K < 1 m/day
Groundwater
• Definitions
– Formations types with respect to water bearing
• Aquifer = permeable layer that contains and transmits water in large quantitieswater in large quantities
– Confined
– Unconfined
• Aquiclude = impermeable layer that may contain water but transmissivity is very low
• Aquitard = semi permeable layer that transmits water in the vertical direction only
• Aquifuge = impermeable layer that neither contains nor transmits water
