  • Effects of the movement of rainfall area on flood runoff
  • Runoff analysis using the radar raingage and the verification of runoff model are made in the Kanna River basin (center of Japan). Based on this verification, runoff estimates using the rainfall model are performed and the relationship between
  • the movement of rainfall area and flood runoff is discussed. - (SGA)
  • The comparison of chinese and european stream runoff
  • Agriculture ; Annual variation ; China ; Europe ; Interannual variability ; Runoff ; Stream ; Stream flow ; Water balance ; Watershed
  • This paper compares stream runoff in China in terms of drainage basin, water balance, and regional distribution and regime of stream runoff with that in Europe. These comparative studies have been done in order to deepen the understanding
  • of regional differentiation and the cause of formation of stream runoff in both regions.
  • Progress in the use of drainage network indices for rainfall-runoff modelling and runoff prediction
  • This article reviews progress in the derivation of drainage network indices and their application in modelling the rainfall-runoff relation and predicting runoff characteristics, discusses remaining problems and proposes directions for future
  • Spatial scale influences on modeled runoff for large watersheds
  • The purpose of this paper is to examine the influence of spatially discontinuous date on modeled runoff by testing how differences in the size and number of model units affect the ability of a model to simulate the runoff process in a large
  • A study of mesoscale runoff variability
  • The variability of runoff registered during the campaign field studies indicates the range of uncertainty, due to the application of only the permanent, macroscale hydrological network. This is especially significant when runoff information
  • Stepen na porojnost na rekite v B''lgarija Storm runoff intensity of the rivers in Bulgaria
  • The storm river runoff is defined as an influx of water. Two coefficients are recommended to find out the storm runoff intensity. - (SBV)
  • Runoff modifications in forest areas
  • Data from representative basins demonstrate the moderating effect of forested areas on runoff. This reduction was analysed in detail for peak discharges and runoff coefficients.
  • Effects of land use on surface runoff - simulations with the erosion 3D computer model
  • By using the physically based simulation model “EROSION 3D”, surface runoff is systematically investigated under variable land use conditions referring to two small sub-catchments of the Striegis River in Saxony (Germany). The paper deals
  • with surface runoff, land use, flood prevention, runoff coefficient, runoff simulation and “EROSION 3D”. - (IfL)
  • Differences in hillslope runoff and sediment transport rates within two semi-arid catchments in southeast Spain

  • This paper focuses on hillslope runoff and sediment transport within 2 catchments in southeast Spain. 5 monitoring sites were established on hillslope concavities throughout the 2 catchments. The techniques used were mini-crest stage recorders
  • , spray-painted lines, sediment traps and tipping bucket rain gauges. Sediment transport and depth of runoff varied dramatically with lithology; marl sites produced most runoff and sediment transport.
  • A deterministic simulation model for rainfall-runoff relationship on arid hillslopes
  • The influence of rainfall distribution and morphological factors on runoff delivery from dryland catchments in SE Spain
  • Arid area ; Infiltration ; Land use ; Modelling ; Precipitation ; Runoff ; Spain ; Topography ; Watershed
  • A simplified theoretical model of storm runoff has been combined with analysis of rainfall records to improve understanding of dryland runoff processes in the Guadalentin catchment of SE Spain, and in particular the decrease in runoff fraction
  • with increasing slope length or catchment area. A modified Green-Ampt equation is applied here to give storm runoff estimates for conditions of constant effective rainfall intensity. The rainfall data can then be combined with a Hydrologically Similar Surface
  • (HYSS) analysis of the soil/land use response, and analyses of catchment network morphology and connectivity to forecast the heterogeneous distribution of ephemeral stream runoff.
  • The Nana Kosi watershed, central Himalaya, India. Part 2 : human impacts on stream runoff
  • Agriculture ; Forest ; Himalaya ; Human impact ; India ; Runoff ; Soil erosion ; Stream flow ; Watershed
  • On the most disturbed agricultural land, 60% of annual runoff occurred in July, whereas in oak-pine forest, only ca. 23% falls in that month. - (DWG)
  • A field study on topographical and topsoil effects on runoff generation
  • In order to assess the influence of topographical factors on runoff yield on the rapidly crusting loamy soils of Central Belgium, a further study of runoff yield was undertaken, using a design allowing the separation of slope and topsoil effects
  • The effect of selected physiographic factors on dissolved gypsum transport by simulated runoff on gypsiferous soils
  • In this paper, attention is focused on the following aspects : to determine the role of runoff in the transport of dissolved gypsum, to establish the effect of physiographic factors on the dissolved gypsum yield, to estimate the level of gypsum
  • saturation reached by runoff and to quantify the dissolved gypsum load.
  • A theoretical model for average river runoff
  • The purpose of this paper is to develop a simple mathematical model of ground flow so as to permit computing the long term steady state flow in rivers as the runoff component of the hydrological cycle.
  • An examination of the efficiency of a simple runoff plot sample splitter
  • The study investigated the effect of flow rate, sediment concentration and sediment grain size on the efficiency of a simple runoff plot sample splitter.

  • Using runoff and climatic observations from 37 small watersheds in Hungary a regional climate-runoff relationships has been established. Discussion. This regional relationship is verified only within a relatively narrow range of precipitation

  • and alluvial streams whose runoff is derived from snowmelt or rainfall directly, runoff dominated streams. The term is meant to include surface runoff and subsurface runoff.
  • The effect of soil crust on the generation of runoff on small plots in an arid environment
  • The aim of this research was to study the factors that influence the generation of runoff in small plots under natural rainfall conditions. Factors studied were crust permeability, roughness, soil salt content and time gaps between the rain showers
  • . The field trial was carried out in the Mashash experimental runoff farm in Israel's Negev desert. Runoff was measured on 8 plots using a tipping-bucket system. Results and discussion.
