The IHACRES rainfall–streamflow modelling approach provides a powerful set of techniques for assisting with parametrically efficient regionalization of streamflow response characteristics (unit hydrograph and loss module parameters) from inputs of rainfall, evaporation surrogates and physical catchment descriptor data. Recent work has indicated where further improvements can be made to the mode...

Water quality impacts due to non-point source pollution can be significant particularly in environmentally sensitive areas. They may, however, be difficult to quantify, since the magnitude is heavily influenced by climatic, geomorphologic, lithologic and pedologic characteristics. A conceptual model for continuous daily simulation is proposed to reproduce the quali-quantitative response of a Si...

Article history: Received 16 November 2010 Accepted 9 April 2013 Available online 20 April 2013 This paper assesses conflicts of interest between banks and their client firms via the merger transaction by examining the wealth gain of merger acquirers who were listed on the Tokyo Stock Exchange in 1990–2004. The paper reports two main findings. First, acquiring firms did not gain from their acqu...

A continuous simulation rainfall-streamflow modelling approach that identifies unit hydrographs for total streamflow has been applied to an 11-year record from a national hydrometric monitoring network catchment in the UK. The model is of the parametrically parsimonious conceptual model (PPCM) type that can make efficient use of rainfall, streamflow and air temperature data readily available fr...

In this study, the time–area curve of an ellipse is analytically derived by considering flow velocities within both channel and hillslope. The Clark IUH also solving continuity equation with input to linear reservoir. then evaluated application Seolmacheon basin, a small mountainous basin in Korea. findings study are summarized as follows. (1) can more realistically be hillslope velocities. rol...
