Abstract Understanding climate and human impacts on water storage is critical for sustainable water-resources management. Here we assessed drivers of total (TWS) variability from Gravity Recovery Climate Experiment (GRACE) satellites compared with drought severity irrigation use in 14 major aquifers the United States. Results show that long-term TWS tracked by GRACE dominated interannual most U...

This paper introduces a class of formal grammars made up by augmenting the formalism of context-free grammars with an explicit set-theoretic intersection operation. It is shown that conjunctive grammars can generate some important non-contextfree language constructs, including those not in the intersection closure of context-free languages, and that they can provide very succinct descriptions o...

Conjunctive grammars were introduced by A. Okhotin in [1] as a natural extension of context-free grammars with an additional operation of intersection in the body of any production of the grammar. Several theorems and algorithms for context-free grammars generalize to the conjunctive case. Still some questions remained open. A. Okhotin posed nine problems concerning those grammars. One of them ...

Economic models and watershed provide useful results, but when seeking to integrate these systems, the temporal units typically utilized by must be reconciled. A hydrologic-economic modeling framework is built couple Hydrological Simulation Program-Fortran (HSPF), representing system, with Rectangular Choice-of-Technology (RCOT) model, an extension of basic input-output (I-O) model. This implem...
