The soil part of wflow_sbm model has its roots in the topog_sbm model but has had considerable changes over time. topog_sbm is specifically designed to simulate fast runoff processes in small catchments while wflow_sbm can be applied more widely. The main differences are: The unsaturated zone can be split-up in different layers.

This Analysis/Model Report (AMR) documents the development of an expected-case model for unsaturated zone (UZ) flow and transport that will be described in terms of the representativeness of models of the natural system. The expected-case model will provide an evaluation of the effectiveness of the natural barriers, assess the impact of conservatism in the Total System Author: C. Ahlers. MODFLOW is the U.S. Geological Survey modular finite-difference flow model, which is a computer code that solves the groundwater flow program is used by hydrogeologists to simulate the flow of groundwater through source code is free public domain software, written primarily in Fortran, and can compile and run on Microsoft Windows or Unix-like operating systems.

Geological Techniques and Methods Book 6, Chapter A19, 62 p. Unsaturated Zone Hydrology for Scientists and Engineers The first edition of this book was published by Prentice Hall in It has been widely recognized as one of the finest books in the field of unsaturated zone hydrology for upper division and graduate level courses, as well as ‘the’ reference book.
The unsaturated zone, often called the vadose zone, is the portion of the subsurface above the water table. It contains, at least some of the time, air as well as water in the pores.
Its thickness can range from zero, as when a lake or marsh is at the surface, to hundreds of meters, Documentation of the Unsaturated-Zone Flow book is common in arid regions.

MODFLOW 6 presently contains one type of hydrologic model, the Groundwater Flow (GWF) Model. The GWF Model for MODFLOW 6 is based on a generalized control-volume finite-difference (CVFD) approach in which a cell can be hydraulically connected to any number of surrounding cells.
Users can define the model grid using. Niswonger, R.G., Prudic, D.E., and Regan, R.S.,Documentation of the Unsaturated-Zone Flow (UZF1) Package for modeling unsaturated flow between the land surface and the water table with MODFLOW U.S.

Geological Survey, Information Services [distributor], (DLC) (OCoLC) This report documents the Groundwater Flow (GWF) Model for a new version of MODFLOW called MODFLOW 6.
The GWF Model for MODFLOW 6 is based on a generalized control-volume finite-difference approach in which a cell can be hydraulically connected to any number of surrounding cells. Users can define the model grid using one of three discretization packages, including (1) a structured Cited by: unsaturated zone flow.
The basic goal of this research group is to measure, predict, and understand the flow of water through the soil and rock between the land surface and the water table, known as the unsaturated or vadose zone.
Many large-scale problems – water quality, water supply and availability, natural aquifer recharge and artificial. The Geochemist's Workbench is the standard for geochemical modeling in aqueous systems. Use the GWB to create Eh-pH diagrams, calculate speciation in solution, trace reaction paths, model reactive transport in flowing groundwater, and much more.
The unsaturated zone is particularly important at sites in the arid western United States that are being relied upon to isolate a significant portion of the Nation's radioactive and other hazardous wastes for periods up to thousands of years.
The MODFLOW One-Water Hydrologic Flow Model (MF-OWHM; Boyce and others, ; Hanson and others, ) is a MODFLOW based integrated hydrologic model designed for the analysis of conjunctive-use management. The term “integrated” refers to the tight coupling of groundwater flow, surface-water flow, landscape processes, aquifer compaction and subsidence, reservoir.
The purpose of this Analysis/Model Report (AMR) is to document natural and anthropogenic (human-induced) analog sites and processes that are applicable to flow and transport processes expected to occur at the potential Yucca Mountain repository in order to build increased confidence in modeling processes of Unsaturated Zone (UZ) flow and transport.
The high concentration of chlorine (36Cl) produced by above-ground nuclear tests (bomb-pulse) provides a fortuitous tracer for infiltration during the last 50 years, and is used to detect fast flow in the unsaturated zone at Yucca Mountain, Nevada, a thick deposit of welded and nonwelded tuffs.
Evidence of fast flow as much as m into the mountain has been found in several zones in a A factor relating to groundwater flow; it is a coefficient that takes into account the permeability of the aquifer and the viscosity of the fluid.

Table B Single-phase flow in the unsat- urated zone—( records).unsaturated zone, immediately below the land surface, contains water and air in the open spaces, or pores.
The saturated zone, a zone in which all the pores and rock fractures are filled with water, underlies the unsaturated zone. The top of the saturated zone is called the water table (Diagram 1). The water table may be just below or hundreds.
