“…It is worth noting that the recession parameter values obtained are very similar to the ones obtained by Beven et al (1984) for some subcatchments of the Hodge Beck and Wye drainage basins. Another difficulty is the actual definition of the water deficit value for a given period, in spite of its fundamental utility for any simulation.…”

“…This topographic index is usually handled in a lumped form to calculate the relative saturated area for every mean water deficit, only requiring the assessment of the mean saturated transmissivity (TO), and an exponential parameter (m), which can both be obtained from baseflow recession measurements (Beven et al 1984). Another way to use the topographic index is in its distributed form, that permits mapping hydrological information.…”

“…As there are no data on the hydrological behaviour of such areas before terracing, we are trying to use some of the hypothesis of the TOPMODEL semidistributed hydrological model (Beven & Kirkby, 1979, Beven et al, 1984 to simulate flows from 'natural conditions' i.e. as if the terraces and drainage channels were not present.…”

PrefaceThis volume comprises papers presented at the fourth conference of the European Network of Experimental and Representative Basins (ERB), which was founded in 1986.The main aims in establishing the Network were to encourage international contacts between scientists and research teams through meetings and data exchanges, and to encourage the creation of joint research projects.The network is managed in Europe by National Correspondents nominated by the Unesco -IHP National Committees of the member countries -Belgium, France, Germany, Italy, Netherlands, Portugal, Spain, Switzerland, UK and, our newest members, the Czech and Slovak Republics.The ERB organises International Conferences at two-year intervals. To date these have been Wageningen, Netherlands September 1992Oxford, EnglandIn addition, an ERB Newsletter is published approximately twice yearly and distributed to 250 scientists worldwide. This covers information about national and intemational activities, and projects, research findings and publications, as well as progress with the ERB Inventory.The ERB Inventory (ICARE) provides a computer database of nearly 100 basins, including their physical characteristics, instrumentation, data, research aims and key publications. The database is maintained and continuously updated by the CEMAGREF in Lyon, France, with information provided by the National Correspondents.The ERB Inventory can be accessed to obtain information about basins which fulfil certain criteria; for example it has been used in the FRIEND Project to identify small research basins in northem and western Europe concerned with physical processes of streamflow generation.The first phase of the ERB Network (1986-91) was concemed with establishing the Network, identifying basins and obtaining descriptive data. Scientific topics of common interest were discussed and several research teams prepared joint research bids to the CEC.The second, and current, phase of the ERB Network has been concemed with moving on from the establishment of the Network to its use. The ERB Inventory has reached a level of completeness where it can be used operationally by scientists to exchange and analyse research results. This offers wide opportunities to perform comparative basin studies.Basin comparisons have been made for many years. This Conference puts special emphasis on the various methods used in such comparative work. The Conference theme focuses on methods of hydrological comparison, and deals with both water quantity and quality. IntroductionThis Publication includes 20 papers from western and central Europe. They cover reports from a broad range of current research on hydrologic comparisons carried out in a number of study sites across Europe and using a wide range of methodological approaches.Each Chapter is presented in the form of a self-contained paper, with its own abstract and reference list, but may also be viewed as a component of this overall Report.The papers are grouped under broad methodological headings for convenience only: basin studies may...

“…For instance, the soil and water assessment tool (SWAT) currently has no water flow among hydrologic response units within a subbasin and therefore no capability to determine different sources (VSAs) of runoff and pollutants in the landscape [Arnold and Fohrer, 2005]. In some cases lumped models, i.e., TOPMODEL [Beven et al, 1984] are capable of delineating saturated areas or VSAs on a larger scale, but may not adequately capture soil moisture or runoff production [Beven, 1997] from heterogeneous landscapes such as in urban areas. Few models couple simplicity with a distributed output.…”

[1] Effective control of nonpoint source contaminants in runoff from urbanized watersheds requires knowledge about the locations of runoff source areas under a variety of conditions. Physical monitoring of spatially variant processes, such as runoff production form variable source areas, is time-consuming and expensive. Thus modeling the processes may provide a valuable cost-effective alternative. In this paper we adapt and validate a variable source model for an urban watershed to predict areas of the landscape prone to elevated soil moisture levels and saturation excess runoff. We modified the soil moisture distribution and routing (SMDR) model to simulate hydrologic processes in an urban upstate New York watershed by considering the impact of impervious surfaces, hydraulic control structures (detention basins), and land use on the water balance. In our model, infiltration excess runoff from impervious surfaces infiltrates in the surrounding soils. Simulated and observed streamflow agreed well, and more importantly, the distribution of soil moisture levels and overland flow throughout the watershed were well predicted. Removing urban features from the model resulted in substantially lower peak stormflows than observed, and the base and interflows increased accordingly. Both modeled and measured distributed results indicated that the more urbanized areas of the study site had both higher soil moistures and runoff losses due to shallower soils, greater upslope contributing areas, and a larger area of impervious surfaces generating runoff. The model results helped identify processes that describe how urbanization impacts integrated and distributed hydrology, which provides useful information for targeted water quality management.

The objective with both modeling approaches is to reduce model complexity leading to lower parameter requirements and computational overhead.…”

Abstract. An alternative to spatial distribution is presented for physically based process modeling of catchment flow and solute transport. The approach is based on an integral relation for catchment streamflow which describes the accumulation through the stream network of the hillslope contributions. This relation is redefined from integration with respect to position along the stream to an integral that is with respect to the physical properties determining the hillslope flow and transport with probability distributions to represent the range of parameter values and areas associated with these. Since the integrand is now a relatively smooth function of the variables of integration, standard numerical integration can be used to evaluate the catchment totals. The assumptions allowing this redefinition are that hillslope hydrology is primarily determined by driving forces that are local to the hillslope and that catchment flow can be lumped in time so that streamflow routing is not required. The interpolation of the integrand involved in the numerical integration results in significant savings over physically based spatially distributed catchment flow and transport models. The methodology is tested through application to an irrigated catchment where model simulations of flow and transport were found to be in close agreement with those observed.
