Of interest to both the theoretical modeling community and to the field researcher, it explores the major hydrological processes encountered in the field, in the laboratory and through computer modeling. As such, the text is seen as a major contribution in the search for initiatives linking hillslope hydrology modeling, field methods for parameterization and new conceptualization based on field observation. Among the many topics covered are: vegetation and hydroclimate, determination of hydraulic soil properties, soil water hysteresis, surface sealing and infiltration, overland flow and erosion, hydrogeochemistry of snow and snowmelt, subsurface runoff, solute transport in soils and runoff production in peat-covered catchments. Each chapter provides state of the art discussions and indicates areas where further research is needed.

A complete guide to the behavior of water on graded land Hillslope Hydrology provides a comprehensive introduction to the behavior of water on a slope. Describing the fates of precipitation, the mechanics of runoff, and the calculations involved in assessment, this book clarifies the complex interplay of soils, sediment, subsurface flow, overland flow, saturation, erosion, and more. An ideal resource for graduate students of Earth science, environmental science, civil engineering, architecture, landscape management, and related fields, this informative guide provides the essential information needed to work effectively with graded land or predict outcomes of precipitation.

Process and Form in Geomorphology marks a turning point in geomorphological research. Stoddart has brought together a team of the leading international experts to offer important new studies into the processes, theory and history of landforms, and to present a framework for taking research forward into the new millenium. Illustrated throughout, Process and Form in Geomorphology takes up the challenges of the research agenda set by Richard Chorley and offers fresh insights into his unique contribution.

This dissertation re-examines the now standard perceptual model of hillslope hydrological response to rainfall, which includes the growth of a saturated wedge at the soil-bedrock interface or impeding layer. It also challenges the notion of bedrock impermeability and the assumption that the pattern of subsurface stormflow is determined by the soil moisture pattern. The results presented in this dissertation challenge the status quo model and show that at the Panola Mountain research hillslope, subsurface storm flow is a threshold-function of precipitation. This threshold is a result of a disconnection between transient saturated areas and the slope base during small to medium size storms (

Landslides are caused by a failure of the mechanical balance within hillslopes. This balance is governed by two coupled physical processes: hydrological or subsurface flow and stress. The stabilizing strength of hillslope materials depends on effective stress, which is diminished by rainfall. This book presents a cutting-edge quantitative approach to understanding hydro-mechanical processes across variably saturated hillslope environments and to the study and prediction of rainfall-induced landslides. Topics covered include historic synthesis of hillslope geomorphology and hydrology, total and effective stress distributions, critical reviews of shear strength of hillslope materials and different bases for stability analysis. Exercises and homework problems are provided for students to engage with the theory in practice. This is an invaluable resource for graduate students and researchers in hydrology, geomorphology, engineering geology, geotechnical engineering and geomechanics and for professionals in the fields of civil and environmental engineering and natural hazard analysis.

A special workshop on scale problems in hydrology was held at Princeton University, Princeton, New Jersey, during October 31-November 3, 1984. This workshop was the second in a series on this general topic. The proceedings of the first workshop, held in Caracas, Venezuela, in January 1982, appeared in the Journal of Hydrology (Volume 65:1/3, 1983). This book contains the papers presented at the second workshop. The scale problems in hydrology and other geophysical sciences stem from the recognition that the mathematical relationships describing a physical phenomenon are mostly scale dependent in the sense that different relationships manifest at different space-time scales. The broad scientific problem then is to identify and for mulate suitable relationships at the scales of practical interest, test them experimen tally and seek consistent analytical connections between these relationships and those known at other scales. For example, the current hydrologic theories of evaporation, infiltration, subsurface water transport and water sediment transport overland and in channels etc. derive mostly from laboratory experiments and therefore generally apply at "small" space-time scales. A rigorous extrapolation of these theories to large spatial and temporal basin scales, as mandated by practical considerations, appears very difficult. Consequently, analytical formulations of suitable hydrologic theories at basin wide space-time scales and their experimental verification is currently being perceived to be an exciting and challenging area of scientific research in hydrology. In order to successfully meet these challenges in the future, this series of workshops was initiated.
