NEW COUNCIL/COMMITTEE PROPOSAL: PAGE 1

Proposed Committee Council Name Task Committee on Distributed Hydrologic Modeling

Parent Committee/Council EWRI Surface Water Hydrology Committee

Committee Purpose (for publication in ASCE Official Register) The purpose of this Task Committee is to appraise new distributed hydrologic modeling technologies, organize special sessions at EWRI conferences on the topic, engage researchers, model developers, and cutting-edge practitioners in forming recommendations to the hydrologic engineering community regarding the state of the art. This Task Committee is a follow-on to the highly-successful Task Committee on GIS Modules and Distributed Models of the Watershed. This new proposed TC differs significantly because many of the GIS and data issues were addressed by the previous TC. The new proposed TC will instead focus on hydrologic science and engineering, modeling needs, parameter selection and estimation, use of alternative data sources (other than rainfall and runoff), scale effects on parameters and models, and automated model calibration techniques. See the enclosed amplification (Page 4 of this proposal). 

Committee Objectives (Publication or other end product) The TC activities will result in a published Nomograph on distributed hydrologic modeling. The main objective of this publication is to describe state-of-the-art modeling techniques that exist at time of publication, and present a compilation of relevant study results from the literature. This primary objective is aimed at cutting-edge practitioners of hydrologic engineering. The secondary objective of the TC publication is a thoughtful compilation of research and development needs. This portion of the report will serve to address the increasing need for distributed hydrologic modeling methods related to new regulatory requirements (e.g. TMDL) and hydrologic science questions related to climate change.

Amplification:

The International Francqui Chair Workshop on the Future of Distributed Hydrologic Modeling, was held 12-15 April, 2000, in Leuven, Belgium. This workshop was attended by distributed hydrologic model developers and users from around the world. The workshop summary includes a number of pressing issues facing all distributed hydrologic model developers and users.

The following questions were posed by the workshop organizer, Keith Beven, during the workshop:

· How can we improve process descriptions without introducing more parameter identifiability problems?

· How can we deal with the scale dependence of parameter values?

· How can we deal with the dependence of effective parameter values on model implementation?

· How can we best use "global" databases to deal with the problem of uniqueness of place?

· Is there really an equifinality (non-unique calibration) [Beven, 1993] problem or is thisjust a problem of inappropriate or inadequate observations or the limitations of current model structures?

· What type of observations will have the greatest value in constraining the predictive uncertainty of distributed models?

· Is there an alternative approach to distributed modeling that could replace (rather than extend) the Freeze and Harlan [1969] blueprint?

The following questions arose from workshop participants during the workshop:

· How simple can a distributed hydrologic model be?

· How/when can distributed models be applied without calibration, given that parameter values are scale dependent?

· Can we use stochastic variability to improve model performance?

· How do we go about discussing differences between models?

· Is there a physically-based distributed hydrologic model at the scales of interest?

· Will faster computers that allow finer discretizations help solve the problem?

· Will additional data sources that allow consideration of additional processes not considered in current model formulations help solve the problem?

· How do we quantitatively describe model performance using terms such as: very good, good, fair, poor?

· How do we preserve detailed processes and information at larger space/time scales?

· How do we condition/evaluate predictions of the impact of catchment/climate changes?

· How do we visualize uncertainty in distributed predictions?

· Will the use of model formulations that can be updated using remote sensing or other data sources (data assimilation) restore faith in the distributed approach or merely continuously compensate for model formulation errors?

· How accurate are our rainfall inputs?

· Should model developers be doing more field work?
