Abstract: Two empirical precipitation disaggregation models are developed for use in continuous hydrologic modeling. The first model is developed for use in disaggregating hourly rainfall data into 20‐min intervals. The second model ...

Abstract: An implicit mathematical model is developed for use in calibrating hydraulic network models. The calibration model uses a nonlinear optimization algorithm along with a general network solver to adjust selected model ...

Abstract: A least‐cost methodology is presented for use in upgrading existing single‐source water‐distribution networks in order to sustain any single component failure (link or node). The methodology is developed by casting the ...

Abstract: This paper describes the development of an optimal water quality tool for managing wet weather discharges that uses a macrolevel simulation model (i.e., the Streeter-Phelps equation) linked with a highly efficient optimization ...

Abstract: An iterative heuristic is proposed to improve the distribution of isolation valves within an existing water distribution network to decrease the magnitude of service interruptions while using the minimum number of valves ...

Abstract: Isolation valves are a fundamental element of water distribution systems because they provide the ability to disconnect sections of the network, which is essential to address routine maintenance and emergency conditions. ...

Abstract: Following an increased emphasis on watershed management by the U.S. Environmental Protection Agency (EPA) in the 1990s, the Kentucky Division of Water (KDOW) developed and implemented a watershed-management framework process ...
