A diagnostic approach to constraining flow partitioning in hydrologic models using a multiobjective optimization framework
Shafii, Mahyar; Basu, Nandita; Craig, James R.; Schiff, Sherry L.; Van Cappellen, Philippe (American Geophysical Union, 2017-04-21)Hydrologic models are often tasked with replicating historical hydrographs but may do so without accurately reproducing the internal hydrological functioning of the watershed, including the flow partitioning, which is ... -
The pie sharing problem: Unbiased sampling of N+1 summative weights
Mai, Juliane; Craig, James R.; Tolson, Bryan A. (Elsevier, 2022-02)A simple algorithm is provided for randomly sampling a set of N+1 weights such that their sum is constrained to be equal to one, analogous to randomly subdividing a pie into N+1 slices where the probability distribution ... -
A priori discretization error metrics for distributed hydrologic modeling applications
Liu, Hongli; Tolson, Bryan A.; Craig, James R.; Shafii, Mahyar (Elsevier, 2016-12-01)Watershed spatial discretization is an important step in developing a distributed hydrologic model. A key difficulty in the spatial discretization process is maintaining a balance between the aggregation-induced information ...
