Pattern, process, and function in landscape ecology and catchment hydrology – how can quantitative landscape ecology support predictions in ungauged basins (PUB)?

چکیده

The understanding of landscape controls on the natural variability of hydrologic processes is an important research question of the PUB (Predictions in Ungauged Basins) initiative. Quantitative landscape ecology, which aims at understanding the relationships of patterns and processes in dynamic heterogeneous landscapes, may greatly 5 contribute to this research effort by assisting the coupling of ecological and hydrological models. The present paper reviews the currently emerging rapprochement between ecological and hydrological research. It points out some common concepts and future research needs in both areas in terms of pattern, process and function analysis and 10 modelling. Focusing on riverine landscapes, the interrelation between ecological and hydrological processes are illustrated. Two further complementary examples show how both disciplines can provide valuable information for each other. I close with some visions about promising (landscape) ecological concepts that may help advancing one of the most challenging tasks in catchment hydrology: Predictions in ungauged basins. 15

Towards a new generation of hydrological process models for the meso-scale: an introduction

The main motivation for this special issue of Hydrology and Earth System Sciences is the IAHS decadal research initiative “Predictions in Ungauged Basins” (Sivapalan et al., 2003), and more specifically the need to develop hydrological models that work for the “right reasons” (Kirchner, 2006). This means that a model shall “work” because its structure is based on appropriate representation of t...

Convergence of approaches toward reducing uncertainty in predictions in ungauged basins

[1] The focus in the search for more reliable predictions in ungauged basins (PUB) has generally been on reducing uncertainty in watershed models (mainly their parameters). More recently, however, we seem to remember that the ultimate objective is not to define the parameters of a specific model but to understand the watershed: What behavior do we expect the ungauged watershed to exhibit? And w...

Gauging the ungauged basin : how many discharge measurements are needed ?

Runoff estimation in ungauged catchments is probably one of the most basic and oldest tasks of hydrologists. This long-standing issue has received increased attention recently due to the PUB (Prediction in Ungauged Basins) initiative. Given the challenges of predicting runoff for ungauged catchments one might argue that the best course of action is to take a few runoff measurements. In this stu...
