Hydrology is the science that deals with the processes governing the depletion and replenishment of water resources of the earth's land areas. The purpose of this book is to put together recent developments on hydrology and water resources engineering. First section covers surface water modeling and second section deals with groundwater modeling. The aim of this book is to focus attention on the management of surface water and groundwater resources.
This volume aims at providing a coherent presentation of recent developments and
understanding of heavy metal reactivity in soils. Such an understanding is necessary
in addressing heavy metals concerns in the environment. The implicit framework of
multiple reactivity acknowledges the widely known role played by the various
colloidal surface functional groups in concomitant reactions. This overarching frame
of reference allows unification between molecular structure-reactivity relationships
at one scale and transport processes at the other....
From the early explorers onwards, visitors to the
Arctic and to Antarctica have commented with
great interest on the presence of lakes, wetlands, and
fl owing waters. These environments encompass a
spectacular range of conditions for aquatic life, from
dilute surface melt ponds, to deep, highly stratifi ed,
