-     Simulation model. This event-oriented, distributed parameter model is 
-     designed for erosion, sediment and water quality control planning on 
-     complex, agricultural watersheds.
- <li> It should normally be distributed in your GRASS-package. Note: ANSWERS is 
-      written in C and FORTRAN, and will require a C compiler and a FORTRAN

-<h3>Erosion modelling: AGNPS 5.0 </h3>
+<h3>Hydrological modelling</h3>
 <ul>
- <li> AGricultural Non-Point Source (AGNPS) is a distributed parameter model
-developed by Agricultural Research Service (ARS) scientists and engineers. It
-predicts soil erosion and nutrient transport/loadings from agricultural
-watersheds for real or hypothetical storms i.e., it's an event-based model.
-Erosion modeling is built upon the USLE applied on a storm basis; thus, it uses
-the EI-index for single storm events. Its hydrology is based on the Soil
-Conservation Service Curve Number technique. AGNPS uses another ARS developed
-model named CREAMS to predict nutrient/pesticide and soil particle size
-generation and interaction. Here is a <A HREF=gdp/erosion/agnps/agnps.html> AGNPS Page</A>. 
-Some help about using AGNPS can be found <A HREF=http://pasture.ecn.purdue.edu:80/~engelb/agen526/>here</A>.
-Note: AGNPS 5.0 is written in C.

-<h3>Storm water runoff: r.water.fea</h3>
-<ul>
-<li> r.water.fea is an interactive program that allows the user to simulate 
- storm water runoff analysis using the finite element numerical technique.
-Infiltration is calculated using the Green and Ampt formulation. r.water.fea
-computes and draws hydrographs for every basin as well as at stream junctions
-in an analysis area. It also draws animation maps at the basin level. The 
-software is available within GRASS 4.x/5.x.

-<h3>Hydrologic modelling: r.hydro.CASC2D</h3>
-<ul>
-<li><a href=http://www.engr.uconn.edu/~ogden/casc2d/casc2d_home.html>CASC2D
-page at University of Connecticut</a>
-<li>r.hydro.CASC2D is a physically-based, distributed, raster
-hydrologic model which simulates the hydrologic response of a watershed
-subject to a given rainfall field. Input rainfall is allowed to vary in 
-space and time. Major components of the model include interception, 
-infiltration, and surface runoff routing.  Interception is a process whereby 
-rainfall is retained by vegetation.  Interception is estimated using an 
-empirical three parameter model.  Infiltration is the process whereby 
-rainfall or surface water is pulled into the soil by capillary and 
-gravity forces. The Green and Ampt equation with four parameters is applied 
-to model the event-based infiltration. For continuous soil moisture 
-accounting, redistribution of soil moisture can also be simulated whenever 
-the non-intercepted  rainfall intensity falls below the saturated hydraulic 
-conductivity of the soil.  The redistribution option requires two more soil 
-hydraulic parameters.  Excess rainfall becomes surface runoff and is routed 
-as overland flow and subsequently as channel flow. The overland flow routing 
-formulation is based on a two-dimensional explicit finite difference (FD)  
-technique, while two different FD techniques, one explicit and
-one implicit, provide options for routing one-dimensional channel flow.
-Through a step function, a depression depth may be specified, below which no
-overland flow will be routed.

-<h3>SWAT hydrologic model</h3>
-The Soil and Water Assessment Tool (SWAT) is the hydrologic model
-used in the SWAT/GRASS linkage (USDA/Arnold and others, 1995). SWAT
-is a continuous-time, basin-scale hydrologic model capable of
-complex long-term simulations including hydrology, pesticide and
-nutrient cycling, and erosion and sediment transport. It is a river basin scale model 
-developed to quantify the impact of land management practices in
-large, complex watersheds. SWAT is a public domain model actively 
-supported by the USDA Agricultural Research Service at the
-Grassland, Soil and Water Research Laboratory in Temple, TX.

+<h3>Landscape Analysis: r.le and r.li</h3>

-<li>f.input reads the results of the HEC-2 Water Surface Profile model
-and generates a vector map of water surface elevations at hydraulic
-sections.  The user supplies to f.input a vector map of the hydraulic
-cross sections used in the HEC-2 model along with the HEC-2 model
-results.
-<li>f.econ takes as input the results of f.wsurf along with a
-user-supplied vector map of building sites and two ASCII files of
-economic data.  As output f.econ generates a vector map of total
-damage to each building in the floodplain along with a summary ASCII
-report of flood damages categorized by building types (residential,
-public, ...) and damage type (structure or content).  f.econ also
-reports areal extent of flooding.
