Unsaturated-zone Modeling - Progress, Challenges and Applications
Edited by R A Feddes, G H de Rooij, J C van Dam
Mankind has manipulated the quantity and quality of soil water for millennia. Food production was massively
increased through fertilization, irrigation and drainage. But malpractice also caused degradation of immense
areas of once fertile land, rendering it totally unproductive for many generations. In populated areas, the pollutant
load ever more often exceeds the soil's capacity for buffering and retention, and large volumes of potable
groundwater have been polluted or are threatened to be polluted in the foreseeable future. In the past decades,
the role of soil water in climate patterns has been recognized but not yet fully understood.

The soil-science community responded to this diversity of issues by developing numerical models to simulate the
behavior of water and solutes in soils. These models helped improve our understanding of unsaturated-zone processes
and develop sustainable land-management practices.
Aimed at professional soil scientists, soil-water modelers, irrigation engineers etc., this book discusses our progress
in soil-water modeling. Top scientists present case studies, overviews and analyses of strengths, weaknesses,
opportunities and threats related to soil-water modeling. The contributions cover a wide range of spatial scales,
and discuss fundamental aspects of unsaturated-zone modeling as well as issues related to the application of models
to real-world problems.
