This comprehensive work integrates knowledge from physics, chemistry, biology, mathematics, geology, engineering, and several other fields. Its purpose is to provide solution methods, techniques of parameter estimation, and tools for solving the complex problems of mathematical modeling. The main topics presented include fundamentals of mathematical modeling of migration processes; analytical, numerical, and inverse solutions to migration problems; and techniques of parameter estimation and moni...
This new volume addresses the global water crisis by presenting new ways to use irrigation water judiciously through innovative fertigation management. It looks at the research and review work done throughout the world on micro irrigation and the techno-economic feasibility of various fertigation irrigation water management systems. Taking a multidisciplinary perspective, the chapters look atusing fertigation to increase the effectiveness of irrigation systemscrop performance evaluation of vari...

C509-15 Resilient-Seated Gate Valves for Water Supply Service
by American Water Works Association
This standard describes resilient-seated gate valves with nonrising stems (NRS) and outside screw-and-yoke (OS&Y) rising stems, including tapping gate valves for water supply service. The resilient-seated gate valve has been in service in various water utility applications since 1975.
This standard covers the material, application, and field-procedure requirements for protective exterior coatings consisting of heat-shrinkable cross-linked polyolefin coatings and their application to special sections, connections, and fittings to be used.
Long-term Process-based Morphological Modeling of Large Tidal Basins
by Ali Dastgheib
The study presented in this book is a part of a collective effort to bridge the existing gap of our understanding of morphological behavior of tidal basins between engineering and geological time scales by extending the use of coastal engineering tools (process-based models) to geological time scales. The Dutch Waddenzee is chosen as the case study and the working hypothesis that 'If you put enough of the essential physics into the model, the most important features of the morphological behavior...
This standard sets requirements for all-hazards risk and resilience analysis and management for the water sector and prescribes methods that can be used for addressing these requirements.
The protection of water resources from deterioration in quality by pollution discharges is probably the biggest challenge in sustainable water resources management in the recent decades. In practice, most countries have adopted pollution control strategies and measures which are based on ‘end-of-pipe’ solutions: wastewater treatment plants and adjustments to the regulations, including taxes for wastewater discharges (Conventional Strategy). Although this approach involves very high costs, on man...

Awwa C519-18 High Performance Waterworks Butterfly Valves - 3 In. (75 MM) Through 60 In. (1,500 MM)
by AWWA
Pesticide Risk in Groundwater
Pesticide pollution of groundwater results from agricultural practices, the properties of the substance and its behavior in the soil environment, and the characteristics of aquifers and their vulnerability. Pesticide Risk in Groundwater provides an overview of the main issues concerning pesticide pollution of groundwater worldwide.The book is divided into five sections. Section I reviews experimental data of groundwater monitoring to indicate the extent of the problem on a global basis. Based on...

This standard covers underground installation and hydrostatic testing procedures for polyvinyl chloride (PVC) and molecularly oriented polyvinyl chloride (PVCO) pressure pipe and fittings that comply with either ANSI/AWWA C900, ANSI/AWWA C905, or ANSI/AWWA C907.
C110-12 Ductile-Iron and Gray-Iron Fittings
by American Water Works Association
This standard covers 3- to 48-in. (76- to 1,219-mm) gray-iron and/or ductile-iron fittings to be used with ductile-iron pipe for water.
C504-15 Rubber-Seated Butterfly Valves
by American Water Works Association
This standard covers rubber-seated butterfly valves, 3 in. (75 mm) through 72 in. (1,800 mm) in diameter, with various body and end types, for fresh and reclaimed water having a pH range from 6 to 12 and a temperature range from 33 to 125F (0.6 to 52C).
Guidelines of Lake Management
Resolving customer water quality complaints is one of the most important aspects of maintaining a successful water distribution system. Complaint investigation involves not just professional water quality proficiency, but also customer relationship skills. The Water Quality Complaint Investigators Guide covers 90% of the most common complaints from consumers.This revised edition focuses on operational practices and includes two entirely new chapters that address regulatory issues and operational...
The purpose of this standard is to provide purchasers, manufacturers, and suppliers with the minimum requirements for PVCO pressure pipe, 4 in. (100 mm) and larger, for potable water, wastewater, and reclaimed water service.
