IAHR, founded in 1935, is a worldwide independent member-based organisation of engineers and water specialists working in fields related to the hydro-environmental sciences and their practical application. Activities range from river and maritime hydraulics to water resources development and eco-hydraulics, through to ice engineering, hydroinformatics, and hydraulic machinery.

Modelling hydrological change: a case study exploring the challenge of modelling the impact of strip mining over specific time increments on an ungauged, pristine catchment
Author : May-Le Ng, G. Hadzilacos, A. Vitale, B. Loney
Strip mining operations have the potential to significantly alter hydrological processes. The activities carried out over a given area during strip mining operations can vary considerably over the operationís life-time. Numerous models have been developed to quantify the impacts of land-use change on hydrological processes but few have considered the effect of incremental changes on the hydrology of the affected area over time. This case study explores a simple modelling approach quantifying the effects of strip mining on hydrological patterns over 10 different stages during a 30 year period of a proposed strip mining operation in Australia. The paper describes the calibration of an AWBM model, a non-distributed, dual storage rainfall-runoff model, using short term observed data for calibration in the absence of any long-term flow data. The paper discusses the validity of this approach in assessing the hydrological change arising from such a development and its contribution to the overall environmental impact assessment.
