Gary Lewis – författare

For students who expect to become involved in programs that are concerned with the development, management and protection of water resources.

The 5th Edition of Introduction to Hydrology has been redesigned to better acquaint future water engineers, scientists and managers with the basic elements of the hydrologic cycle. Its focus is on presenting the principles of hydrology in the context of their application to real-world problems. The book identifies data sources, introduces statistical analyses in the context of hydrologic problem-solving, covers the components of the hydrologic budget, discusses hydrograph analysis and routing, and introduces groundwater hydrology, urban hydrology, hydrologic models and hydrologic design. Many solved examples and problems serve to amplify the concepts presented in the text. Computer applications are discussed and appropriate Web addresses are provided.

Dark Poetry: Pieces of the Paradox is a short collection of some of the best dark art and rhyming poetry by Gary Lewis, author of the Three Worlds series of poetry books which include Paradoxium, Inevitum, and Relativium. The author takes every opportunity to mix the mysterious, the imaginary, the real, the open, and the secret, in order to take the reader away on a cryptic journey through the depths of their own perceptions.

“A magnum opus of ground covers that deserves a place in every gardener’s library.” —Tony Avent, founder and owner Plant Delights Nursery Ground covers are widely thought of as utilitarian—we turn to them when we have a problem that needs a solution. Yet these plants also offer a diverse range of beautiful and intriguing options with a variety of colors, textures, and forms. They can unify a landscape, knit together plantings and hardscape, and add extra layers of beauty, dynamism, and surprise. As a replacement for lawns, they can reduce our use of water, fertilizer, pesticides, herbicides, carbon-based fuels, and transform a yard into a diverse landscape of habitat and food for native insects, birds, and other wildlife. In this meticulously researched reference, nurseryman Gary Lewis profiles more than 4000 ground covers that can perform these roles with aplomb. No matter what kinds of conditions you’re facing—shade, dry soil, heavy clay, excess moisture—there’s a ground cover that will thrive and beautify your garden. Comprehensive, practical, and copiously illustrated, this indispensable volume belongs on the shelf of every designer, landscape architect, and serious gardener.
