Description
HiWaQ coupling tests with EcH2O-iso and mHM in the Silberhütte catchment

This repository contains all data associated to the publication: Yang, X., Tetzlaff, D., Soulsby, C.,& Borchardt, D. (2022), HiWaQ v1.0: A flexible catchment water quality assessment tool with compatibility for multiple hydrological model structures (submitted to Geoscientific Model Development).

Background

Mitigating diffuse-source nutrient pollution has created an urgent need to advance understanding of catchment hydrological and nutrient dynamics, and develop robust integrated hydrological and water quality models to support decision making. The newly developed HiWaQ aims to be compatible with multiple, often contrasting hydrological model structures and comprehensively considers spatio-temporally varying water quality impacts of anthropogenic activities. The model has the unique value of making better use of advanced hydrological modelling that embeds thoughtful modelling workflows and localised perceptual knowledge, thus better leveraging these advancements in the integrated catchment water quantity-quality assessments.

The nitrogen module HiWaQ-N (adapted from Yang et al.,2018) and its coupling tests with the process-based ecohydrological EcH2O-iso model and the multi-scale conceptual mHM model. EcH2O-iso is a fully distributed, process-based ecohydrological model, which integrates modules of energy balance, water balance, vegetation dynamics and flux tracking based on stable isotopes of water (Kuppel et al., 2018a; Maneta and Silverman, 2013). The mesoscale Hydrological Model mHM (Samaniego et al., 2010) is a fully distributed, HBV-type model, with multiscale parameter regionalization technique.

Results and instructions

Two subfolders contain all coupling configurations and testing data for the EcH2O-iso coupling and the mHM coupling i.e., ./ech2o-iso_coupling/ and ./mhm_coupling/, respectively. Each subfolder contains:

(1) hiwaq. The pre-compiled model executable file for the Linux system.
(2) wqm_config.nml. The coupling interface and all model configurations.
(3) wqm_parameter.nml. The parameter file of the HiWaQ-N model.
(4) wqm_outputs.nml. This file allows the users to write out detailed spatial information of catchment N state variables and fluxes. The output format is NetCDF (.nc).
(5) “./selke/catchinfo/”. This folder contains all information of the testing in the Silberhütte catchment (99 km2, a upland subcatchment of the well-studied Selke catchment, central Germany).
(6) “./selke/gagues/”. This folder contains all evaluation data, including the observed discharge and/or nitrate-N concentration data at different gauging station.
(7) “./selke/hydro/”. This folder contains all hydrological fluxes and state variables computed from the coupled hydrological simulation. The NetCDF format is encouraged.
(8) “./selke/output/”. This folder stores all HiWaQ-N outputs.
