1.4.0 Introduction
A water resources systems planner is fac
ed with the challenge of
conceptualizing
a project to meet the specific needs at
a minimum cost. For a demand intensive
project, the size of the proj
ect is limited by the availability of water. The planner
then has to choose amongst the alternatives and determine the optimum scale of
the project. If it is a multi-purpose project, an allocation of costs has to be made
to those who benefit from t
he project. An important aspec
t of planning is that it
has to prepare for a future date – its effe
cts in terms of physical quantities and
costs over a period of time spanning the usef
ul life of project has to be evaluated.
The return expected over the proj
ect period has to be calculated.
All this requires broader decisions, which
affect the design details of the project.
This chapter looks into the different aspec
ts of preparing a project plan likely to
face a water resources system planner,
including the basic assessment of data
that is primary to any
project plan formulation.
8. Data collection for environment, socio-economic and demographic
informations
9. Data collection methods for topography, geology, rainfall and stream flow.
