Derivation of near-optimal pump schedules for water distribution by simulated annealing [PDF]
, 2004 The scheduling of pumps for clean water distribution is a partially discrete non-linear problem with many variables. The scheduling method described in this paper typically produces costs within 1% of a linear program-based solution, and can incorporate ...

Unified Friction Formulation from Laminar to Fully Rough Turbulent Flow [PDF]
, 2018 This paper provides a new unified formula for Newtonian fluids valid for all pipe flow regimes from laminar to fully rough turbulent flow. This includes laminar flow; the unstable sharp jump from laminar to turbulent flow; and all types of turbulent ...

Influence of hydraulic resistance on flow features in an open channel confluence [PDF]
, 2014 A numerical model based on the 3D shallow water equations is set up for a 90° angle open channel confluence. The model is first calibrated and validated using experimental data by (Shumate, 1998).

Mitigation of flash floods in arid regions using adjoint sensitivity analysis [PDF]
, 2007 This paper presents an analysis of the sensitivities of flood wave propagation to variations in certain control variables and boundary conditions by means of the adjoint method.

Process description of SWQN : A simplified hydraulic model [PDF]
, 2009 SWQN is a simplified hydraulic model for surface water systems which computes water levels and flows in a network of nodes labelled as ‘volumes’ and segments labelled as ‘connectors’.
