Hydrology - IHACRES

Description
The metric conceptual rainfall-runoff model IHACRES (Identification of unit Hydrographs and Component flows from Rainfall, Evaporation and Streamflow data) has been implemented as a module library. The IHACRES model was developed by: Jakeman, A.J. and G.M. Hornberger (1993); Jakeman et al. (1990), see reference list for more details.

A compiled version of the module library is available for windows only (.dll). Maybe someone could compile it for Linux also.
The code urgently needs a revision. It was implemented in a quick and dirty way. Nevertheless, I tested the current version and it works under SAGA 2.0.2 and lower versions. Unfortunately, it works not yet with the current version 2.0.3. You can download version 2.0.2 here. In case the download starts not automatically: right-click on the link and choose "Save target as..." or whatever comparable command your browser provides.

Module Name
IHACRES

• IHACRES Version 1.0: Streamflow simulation (mean catchment input of precipitation and temperature)
• IHACRES Calibration (2): Model calibration, based on Monte-Carlo approach
• IHACRES Elevation Bands: Streamflow simulation (data input separated in elevation bands)
• IHACRES Elevation Bands Calibration:Calibration tool for elevation bands

Purpose
The module can be used to simulate streamflow (catchment runoff) on the basis of daily rainfall and temperature data. No spatial data, such as elevation models, soil or land use maps are required.

IHACRES has been applied to catchments with a wide range of climatologies and sizes (Croke et al., 2004). It has been used to predict streamflow in ungauged catchments (Kokkonen et al., 2003; Post and Jakeman, 1999; Post et al., 1998), to study land cover effects on hydrologic processes (Croke et al., 2004; Kokkonen and Jakeman, 2002), and to investigate dynamic response characteristics and physical catchment descriptors (Kokkonen et al., 2003; Sefton and Howarth, 1998).
More recently, the model has been used to develop a rainfall-runoff database for flood risk assessment and forecasting by Liersch, S. and M. Volk (2008) (pdf).
