Abstract: This paper presents the development of tests based on one artificial intelligence technique, the Kohonen neural network, for the detection of shifts in hydrometric data. Two new Kohonen-based detection tests are developed, ...

Abstract: An approach is developed for identifying key data to be used in asset management in general, and for predicting pipe breaks and selecting appropriate models in particular. The approach is applied to the District of Maple ...

Abstract: In cast-iron pipes, chlorine consumption due to internal corrosion is high compared with consumption caused by other water-quality factors in such systems and may be considered as an approximate indicator of the rate of ...

Abstract: The evaluation of crossing probability for a given threshold level of a discrete process is an important modeling issue in stochastic hydrology. Rice’s formula is a tool to measure the instantaneous crossing rate for a ...

Abstract: Traditional approaches for repeatedly updating reliability estimates, as needed in reliability-based optimal designs or real-time system control, require the iterative application of a reliability method. This paper explores ...

Abstract: Design of water distribution networks (WDNs) is classified as a large combinatorial discrete nonlinear nondeterministic polynomial-hard (NP-hard) optimization problem. The main concerns associated with the optimization of ...

Abstract: A novel approach for including uncertainty in the water‐quality‐management process is presented. The approach is based on the use of multiple scenarios that reflect possible combinations of hydrologic, meteorologic, and ...

Abstract: A Chebyshev criterion is used to develop robust direct regulation water-quality management models. The reserve capacity of the stream, in terms of the excess capacities above the water-quality goal at the most critical ...

Abstract: Seasonal waste discharge (SWD) programs allow different waste-discharge rates during different seasons of the year and reduce the cost of waste treatment. The efficiency of such programs for managing biochemical oxygen ...
