The story begins with a mysterious egg washed up on a Scottish beach, the morning after a great storm.
A nice relaxing holiday in a lakeside paradise. That's exactly what the Cranberry family had in mind - until they arrived at Grey Bluff Lake. There's nothing relaxing about a drought! Can they learn to use less water - and still enjoy the summer?
The staircase wound round and round and round, till the prince was almost giddy, and every now and then he caught sight of a large room that opened out from the side. But he had been told to go to the top, and to the top he went. Then he found himself in a hall, which had an iron door at one end. This door he unlocked with his golden key, and he passed through into a vast chamber which had a roof of blue sprinkled with golden stars, and a carpet of green silk soft as turf. Twelve windows framed in gold let in the light of the sun, and on every window was painted the figure of a young girl, each more beautiful than the last. While the prince gazed at them in surprise, not knowing which he liked best, the girls began to lift their eyes and smile at him. He waited, expecting them to speak, but no sound came.
Arid and semi-arid regions face major challenges in the management of scarce freshwater resources under pressures of population, economic development, climate change, pollution and over-abstraction. Groundwater is commonly the most important water resource in these areas. Groundwater models are widely used globally to understand groundwater systems and to guide decisions on management. However, the hydrology of arid and semi-arid areas is very different from that of humid regions, and there is little guidance on the special challenges of groundwater modelling for these areas. This book brings together the experience of internationally leading experts to fill a gap in the scientific and technical literature. It introduces state-of-the-art methods for modelling groundwater resources, illustrated with a wide-ranging set of illustrative examples from around the world. The book is valuable for researchers, practitioners in developed and developing countries, and graduate students in hydrology, hydrogeology, water resources management, environmental engineering and geography.
