Computer program documentation is important to proper model use. Common causes of poor documentation include: organizational negligence and lack of capability, difficulty in clearly communicating a description of the model, motivation on the part of the modeler to prepare good documentation, absence of examples of good documentation, inadequate time funds, staff.

This revised, updated textbook presents a systems approach to the planning, management, and operation of water resources infrastructure in the environment. Previously published in 2005 by UNESCO and Deltares (Delft Hydraulics at the time), this new edition, written again with contributions from Jery R. Stedinger, Jozef P. M. Dijkman, and Monique T. Villars, is aimed equally at students and professionals. It introduces readers to the concept of viewing issues involving water resources as a system of multiple interacting components and scales. It offers guidelines for initiating and carrying out water resource system planning and management projects. It introduces alternative optimization, simulation, and statistical methods useful for project identification, design, siting, operation and evaluation and for studying post-planning issues. The authors cover both basin-wide and urban water issues and present ways of identifying and evaluating alternatives for addressing multiple-purpose and multi-objective water quantity and quality management challenges. Reinforced with cases studies, exercises, and media supplements throughout, the text is ideal for upper-level undergraduate and graduate courses in water resource planning and management as well as for practicing planners and engineers in the field.
Solutions to human and institutional problems that inhibit effective development and use of water resource computer models are identified. Support of water resource models is treated under the topics of quality control, technology transfer, model improvement and maintenance, and education of managers/decision makers. A main thesis is that effective model support is best achieved by means of centralized organizational units that are designed to perform a wide range of support activities that include model evaluation and enhancement preparation of documentation, user assistance, maintenance, the conducting of training courses and seminars, and project applications.
