Drought and Water‐Supply Management: Roles and Responsibilities
(American Society of Civil Engineers, 1993)Managing drought during the 1980s taught that it is essential to define the roles of local, state, and federal governments. Roles are still being worked out, especially in the cross‐cutting areas of planning and coordination. ... -
Discrete Volume‐Element Method for Network Water‐Quality Models
(American Society of Civil Engineers, 1993)An explicit dynamic water‐quality modeling algorithm is developed for tracking dissolved substances in water‐distribution networks. The algorithm is based on a mass‐balance relation within pipes that considers both advective ... -
New Paradigm for Coordination in Water Industry
(American Society of Civil Engineers, 1993)Without improved coordination of water management, there will be excessive conflict, wasted funds, and unnecessary damage to the environment in the United States. A new paradigm for water‐industry coordination to be ... -
Evaluating Artificial Recharge Needs of Aquifer
(American Society of Civil Engineers, 1993)Ground water is in many cases the only source of drinking water for several Catalan coastal towns in the northeastern corner of Spain. In practice, the management of these water resources is accomplished with only one ... -
Computer‐Aided Optimal Pump Selection for Water Distribution Networks
(American Society of Civil Engineers, 1993)The paper addresses the selection of new pumps as part of a major redevelopment of a large scale urban water‐distribution system in which the locations of existing and planned pumping stations are already established. The ... -
Susceptibility of Reservoirs to Drought Using Palmer Index
(American Society of Civil Engineers, 1993)The Palmer index is a widely used indicator of meteorological drought derived from estimates of moisture deficiency that is computed monthly for 344 climate divisions in the contiguous United States. While not often used ... -
Buffer Zones around Water‐Supply Reservoirs
(American Society of Civil Engineers, 1993)In urbanizing areas, the protection of watersheds draining into potable water reservoirs may present a problem. Growing conflicts are arising between interest in development of land and desire to preserve drinking water ... -
Governmental Priorities in Irrigation Project Selection in Indonesia
(American Society of Civil Engineers, 1993)Irrigation development in Indonesia is directed at both traditional economic efficiency objectives and socioeconomic objectives related to self‐sufficiency in rice production, improved income to individual farmers, and the ... -
Overlooked Market for Water Connections in Rabat's Shantytowns
(American Society of Civil Engineers, 1993)Despite the plentiful supply of water available at no cost in Rabat's shantytowns, a household survey during the summer of 1990 showed that most residents in these areas desire and could pay for individual house connections ... -
Revised Surface‐Water Supply Index for Western United States
(American Society of Civil Engineers, 1993)The surface‐water‐supply index (SWSI) was introduced in Colorado in the early 1980s as a better indicator of water availability in the western United States than is the Palmer drought index. Similar indexes have been ... -
Network Linear Programming Codes for Water‐Supply Headworks Modeling
(American Society of Civil Engineers, 1993)There is a class of water‐supply headworks models that uses network linear programming to assign water within the network. The choice of algorithm and computer code to solve the network linear programs formulated by such ... -
Reservoir‐System Simulation and Optimization Models
(American Society of Civil Engineers, 1993)A broad array of computer models has been developed for evaluating reservoir operations. Selecting a modeling and analysis approach for a particular application depends upon the characteristics of the application, the ... -
Prediction of River Discharge at Ungaged Sites with Analysis of Uncertainty
(American Society of Civil Engineers, 1993)A technique is outlined for assigning uncertainty to the estimation of cumulative probability distribution functions (flow‐duration curves) for river discharge at ungaged sites. Data from existing stage‐discharge gaging ... -
Diagnostic Checking in Stochastic Dynamic Programming
(American Society of Civil Engineers, 1993)A testing procedure to diagnose whether the stochastic dynamic programming (SDP) models for reservoir operations will converge is presented. Theoretically, the stability of SDP can be diagnosed by checking whether a ... -
Conditional‐Yield Operating Rules for Low‐Flow Management
(American Society of Civil Engineers, 1993)A family of reservoir operating rules, termed -
Water‐Quality Modeling with EPA Reach File System
(American Society of Civil Engineers, 1993)The U.S. Environmental Protection Agency (EPA) has developed a geographically referenced data‐base system of the surface‐water features of the United States. This data‐base system is called the Reach File. It was designed ... -
Grouped Response Units for Distributed Hydrologic Modeling
(American Society of Civil Engineers, 1993)This paper introduces a method for distributed hydrologic modeling that eliminates the need for small computational areas while maintaining the requirement of computing runoff for homogenous watershed subareas. The model ... -
Flood‐Flow Frequency Model Selection in Southwestern United States
(American Society of Civil Engineers, 1993)Uniform flood frequency guidelines in the United States recommend the use of the log Pearson type 3 (LP3) distribution in flood frequency investigations. Many investigators have suggested alternate models such as the ... -
Basin‐Scale Modeling as Tool for Water‐Resource Planning
(American Society of Civil Engineers, 1993)A basin‐scale model was developed to simulate long‐term average losses of water, sediment, and nutrients from large rural watersheds. In addition to simulating diffuse sources using the Chemicals, Runoff, and Erosion from ...
