Numerous photos and illustrations throughout the book communicate concepts and information, and engage students with the author's trademark visual approach to the subject.

Current and emerging topics-

• Climate change effects on hydrology,
• Anthropogenic effects on hydrology,
• Sustainability

Development of hydrologic principles-A rigorous, unified, numerical, and analytical approach throughout. The use of the control volume approach with Reynold's transport is used in the development of the conservation of mass, conservation of energy, and the conservation of momentum relationships used in hydrology.

Hydrologic Modeling:

Groundwater modeling is approached through the development of basic concepts and principles including the occurrence and movement of groundwater, and groundwater and well hydraulics. The basic equations used in the MODFLOW model are developed so the student has a basic understanding of how the model works, followed by example applications.

Surface water modeling takes a similar approach to develop the concepts and principles. As an example the fundamental principles for infiltration approaches, the unit hydrograph approach, the hydrologic routing approaches, and the kinematic wave model used in the HEC-HMS model are described in detail. Floodplain analysis principles are developed so that the student has a fundamental understanding of the hydrologic and hydraulic analysis that is performed. Coverage involves the principles of the hydraulic analysis used in the HEC-RAS model for steady-state water surface profile analysis.

Floodplain analysis principles are developed so that the student has a fundamental understanding of the hydrologic and hydraulic analysis that is performed. Coverage includes the principles of the hydraulic analysis used in the HEC-RAS model for both steady-state water surface profile analysis and unsteady flow analysis. Probabilistic approaches not only include floodflow frequency analysis but also rainfall frequency analysis.

Hydrologic Design:

Surface water hydrology related design topics include hydrologic design for water supply and design approaches for stormwater management including: stormwater sewer systems, detention basins, and infiltration basins. Hydrologic design for water supply is also includes evapotranspiration calculations using the Penman-Monteith equation and storage-firm yield analysis and sequent peak analysis. Design coverage also includes approaches for risk/reliability-based design to include the various hydrologic and hydraulic design uncertainties.

Groundwater hydrology related design topics include: aquifer recharge such as soil aquifer-systems, design prevention for salt-water intrusion, and stormwater infiltration basins.

Hydrologic Measurement:

Hydrologic measurement is covered including topics in atmosphere-land interface measurements, discharge measurement, streamflow measurement, subsurface water measurement, and hydrologic monitoring systems.

Hydrology of Specific Climates:

Hydrology of specific climates includes cold climates, semi-arid and arid climates, and humid tropical climates. The discussion of cold climates includes the snowmelt computations under varying conditions. Discussion of semi-arid and arid climates includes not only the hydrology of this climate but also alluvial fan flood modeling for floodplain determination. The discussion of humid climates includes discussion of topics such the hydrologic effects of ENSO, but also topics such as rainfall interception modeling.
