Abstract
Mathematical models are modem tools that proved to be efficient in Water Resources
Planning Jnd i\.lanagement. However~ reliable, sufficient, and accurate data are required to run
those models and obtain useful results. Data and Information are the keys for successful
modelling activities.
Since the amount of data required is huge, it is not feasible to procure the whole set of
data through office \vork and personal contacts. Field data collection is necessary to fill missing
data and also to check the existing infom1ation. Data collected during study visits and meetings
needs investigation, analysis using database systems and also it needs field truthing (checking)
before being suitable for modem application. The required data for the water resources planning
and management models includes configuration and layouts, cropping patterns and water duties,
agro-climatological weather data, hydro-geological data, hydraulic data, soil characteristics,
groundwater attributes, operational data, .... etc.
Remote sensing and Geographic Information System (GIS) are new technologies that
could be used in Water Resources Planning and management. Integrated remote sensing and
GIS tool could be applied for management of the water resources data. Data types that could
be managed by this integrated system include surface and groundwater connected with
monitoring and production data.
1.2 Background of the Problem and Rationale for the Proposed Method
All water resources management models require input data, information on the physical
characteristics of the irrigation and drainage system to be modeled as well as the precise layout
of the canals and drains systems for the study area. If the available data is not accurate, the
results of the models will not be accurate and consequently undependable even if the model
was a powerful model (garbage on garbage). Also, it is necessary to produce recent aod
accurate tools to provide the mathematical models and any new irrigation aod drainage projects
