The most widely and popularly used method for prediction of flood hydrograph resulting from a known storm in a basin area use historical rainfallrunoff data and unit hydrographs derived from them. These procedures are highly unreliable due to the climatic and physical changes in the watershed and their implementation to ungauged catchments. The use of physically based rainfall-runoff estimation...

Over the last 200 years, streams throughout Australia have been channelised to increase their hydraulic conveyance, and so reduce flood peaks and durations. One of the main channelisation activities has been to remove large woody debris (LWD) and bank vegetation. Ironically, the major stream rehabilitation activity in Australia, and in many countries, over the last two decades, has been to reve...

[1] The responses of karstic aquifers to storms are often used to obtain information about aquifer geometry. In general, spring hydrographs are a function of both system geometry and recharge. However, the majority of prior work on storm pulses through karst has not studied the effect of recharge on spring hydrographs. To examine the relative importance of geometry and recharge, we break karsti...

Separation of streamflow components into quickflow and baseflow is usually carried out in two main ways: hydrograph recession analysis and tracer-based methods. In this paper, it is proposed to use a fully coupled surface and subsurface flow and transport model to gain a better understanding of the relationship between physical catchment characteristics (e.g. aquifer hydraulic conductivity) and...
