hydrologic modeling:
approach
Today, hydrologic modeling is an essential
element of many water resources planning and management project.
The benefits of hydrologic models are enormous in water resources
planning because it helps us:
Since hydrologic modeling is a complex task, it
has been observed that the modeling projects are often late and over budget. In
addition, the results of hydrologic modeling are being challenged at the court
in environmental litigations. As a
result, hydrologic models must meet the following criteria:
- Technically sound;
- Representative; (of the physical field problems being studied);
- Credible;
- Well documented;
- Defensible;
- Verifiable;
- Cost Effective; and
- Timely.
At WRIME, Inc., we developed an effective
approach for hydrologic modeling that enables us to meet the above criteria.
Our modeling approach consists of six steps as
shown in the figure below:
This is a goal oriented approach of hydrologic modeling,
rather than an open-ended approach, which often leads to never-ending scientific
experimentation focused on polishing mathematical and computational aspects of
methods and techniques.

“For a good mathematical model it is not enough to work well. It must work
well for the right reasons. It must reflect, even if only in a simplified
form, the essential features of the physical prototype.”
