Parameter Estimation for Water Distribution Networks
(American Society of Civil Engineers, 1991)Calibration of a water distribution network is a long, tedious task, if analyzed by an engineer, with no guarantee of determining the proper system parameters. In addition, more utilities are moving toward automated control ... -

Testing Stochastic Dynamic Programming Models Conditioned on Observed or Forecasted Inflows
(American Society of Civil Engineers, 1991)This paper presents and compares four types of stochastic dynamic programming (SDP) for on‐line reservoir operation, relying on observed or forecasted inflows. The models are different because of the assumptions regarding ... -
Goal‐Programming Techniques for Optimal Reservoir Operations
(American Society of Civil Engineers, 1990)The problem of optimal reservoir operations consists of obtaining optimal releases, reservoir storages, and downstream reach routed flows based on forecasted inflows and precipitation. Five goal‐programming schemes that ... -
Sampling Network Design for Transport Parameter Identification
(American Society of Civil Engineers, 1990)An optimal experimental design algorithm is developed to facilitate the planning and the optimal configuration and scheduling of a ground‐water‐tracer test whose data are to be used to estimate model parameters. A maximal ... -
Optimization of Hydropower Plant Integration in Water Supply System
(American Society of Civil Engineers, 1990)An optimization model is presented for determining the optimal design capacities of a water delivery system integrating small hydropower plants. A discrete distance model of the transmission pipeline is solved by employing ... -
Optimal Upgrading of Hydraulic‐Network Reliability
(American Society of Civil Engineers, 1990)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 ... -

Reconnaissance‐Level Alternative Optimal Ground‐Water Use Strategies
(American Society of Civil Engineers, 1990)This study develops regionally optimal ground‐water extraction strategies. Alternative explicit planning objectives are: (1) Maximize total pumping from the underlying aquifer while causing the evolution of a steady ... -
Finite Element Watershed Modeling: One‐Dimensional Elements
(American Society of Civil Engineers, 1990)A procedure for calculating the spatial and temporal distribution of a direct runoff hydrograph from an ungauged watershed is presented. Nodal values of hydraulic roughness and slope are used to avoid kinematic shock. This ... -
Evaluating Ground‐Water Vulnerability to Pesticides
(American Society of Civil Engineers, 1990)A methodology was developed to rank the relative vulnerability of ground‐water areas to contamination by agriculturally applied pesticides. The method uses the advection‐dispersion equation for chemical transport in soils ... -
Implementation of On‐Line Control Scheme for City Water System
(American Society of Civil Engineers, 1990)The provision of on‐line computer‐based control schemes for water‐supply and distribution systems has for many years eluded the water industry because of the unavailability of reliable applications modules, as well as the ... -
Real‐Time Sampling Strategies for Estimating Nutrient Loadings
(American Society of Civil Engineers, 1990)An investigation of water‐quality sampling strategies, applicable to real‐time sampling programs, is presented. The sampling strategies are designed to be a component of the data‐collection process for the determination ... -
Proposed Model For Evaluating Urban Hydrologic Change
(American Society of Civil Engineers, 1990)Evaluation of the effects of land‐use change in a natural catchment and what can be done to mitigate these effects requires accurate quantitative representation of the mechanisms by which precipitation contributes to run ... -
Opportunities for Reservoir‐Storage Reallocation
(American Society of Civil Engineers, 1990)A review of studies on reallocation of reservoir storage capacity for reservoirs in the Corps of Engineers and state of Texas has identified eight general cases of reallocation: (1) Use of water‐supply storage not under ... -
Infrastructure—Weathering a Boom‐and‐Bust Development Cycle
(American Society of Civil Engineers, 1990)Making wise investments is the goal of every investor. This is certainly true for public utilities as they invest in infrastructure to fulfill their mission of providing safe, reliable, cost‐efficient service to their ...
