LEACHM: Leaching Estimation and Chemistry Model

Dataset Identification:

Resource Abstract:
LEACHM (Leaching Estimation and Chemistry Model) refers to a suite of simulation models describing the water and chemical regime in the soil root zone. LEACHM was developed by John Hutson and Jeff Wagenet, in the Department of Soil, Crop and Atmospheric Sciences at Cornell University, Ithaca, New York. It has undergone numerous extensions and revisions since 1984, many of these in response to the requirements and experience of users around the world. The LEACHM suite consists of four simulation models and several utilities. The simulation models utilize similar numerical solution schemes to simulate vertical water and chemical movement. They differ in their description of chemical equilibrium, transformation and degradation pathways. LEACHW describes the water regime only. The other simulations describe pesticides (LEACHP), nitrogen and phosphorus (LEACHN), and salinity in calcareous soils (LEACHC). The models simulate chemical fate and transport in transient-flow field situations as well as in laboratory columns subject to steady-state or interrupted flow. Water flow and solute transport is described by the Richards and convective-dispersion equations, or by a modified Addiscott mobile/immobile capacity (tipping-bucket) concept. (Source of abstract: http://fiams.es.flinders.edu.au/LeachmDownload/LEACHWEB.HTM) LEACHM requires several soil parameters as input (physical properties, bulk density, particle size distribution, water retention characteristic). It also requires the amount of nitrogen and phosphate, daily maximum and minimum temperature, precipitation and evapotranspiration estimates. The model predicts amount of chemical leaching below the root zone and amount taken up by the plants. The model uses a daily time step and is executed for one growing season or over a several year period.
