“…Perennial stream density in the Northern Rockies ecoregion is relatively high and the values reported range from 0.9 km km −2 to 1.2 km km −2 (McIntosh et al, 1995). Wigington et al (2005) reported that perennial stream density of agricultural watersheds in western Oregon varies from 0.24 km km −2 to 0.66 km km −2 even though the total stream density varies from 2.90 km km −2 to 8.00 km km −2 . The perennial stream density for the four case study watersheds located in western Oregon are 0.1 km km −2 (USGS gage 14308000), 0.26 km km −2 (USGS gage 11497500), 0.29 km km −2 (USGS gage 14080500), and 0.67 km km −2 (USGS gage 11532500) as shown in Fig.…”

Abstract. Connection between perennial stream and base flow at the mean annual scale exists since one of the hydrologic functions of perennial stream is to deliver runoff even in low flow seasons. The partitioning of precipitation into runoff and evaporation at the mean annual scale, on the first order, is captured by the ratio of potential evaporation to precipitation (E P /P called climate aridity index) based on Budyko hypothesis. Perennial stream density (D P ), which is obtained from the high resolution National Hydrography Dataset, for 185 watersheds declines monotonically with climate aridity index, and an inversely proportional function is proposed to model the relationship between D P and E P /P . The monotonic trend of perennial stream density reconciles with the Abrahams curve since perennial stream density is only a small portion of the total drainage density. The correlation coefficient between the ratio of base flow to precipitation (Q b /P ), which follows a complementary Budyko type curve and perennial stream density is found to be 0.74. The similarity between Q b /P and D P reveals the co-evolution between water balance and perennial stream network.

“…Another surprising thing that I learned from these sampling campaigns is that the springs located in the upper part of the catchment are the dominant source for baseflow (Fig. 10a, (Wigington et al, 2005;Godsey and Kirchner, 2014;Jensen et al, 2017) (Fig. 10b, letter G).…”

Runoff generation mechanisms vary between catchments and despite decades of research in many catchments, these mechanisms are still not fully understood. In this paper, runoff generation mechanisms in the steep pre-alpine catchments in the Alptal, Switzerland, are discussed. These fast responding catchments are characterized by low permeability soils on top of flysch bedrock. In combination with the high and frequent precipitation, this results in predominantly wet conditions. In many areas, the water table is close to the surface. We review the main results of recent (2009-2016) studies in these catchments that used isotope, stream chemistry and hydrometric data. These field studies focused on the spatial and temporal patterns in groundwater levels, spatial patterns in the isotopic composition and chemistry of streamflow during baseflow conditions, as well as the responses of streamflow and its isotopic composition during rainfall events. The combined results of these studies highlight the establishment of connectivity of areas with a different topographic position and areas with a different land use during rainfall events. They also show the importance of flow in higher conductivity near surface soil layers for runoff generation, as well as the frequent occurrence of surface runoff. Spatial differences in groundwater dynamics are related to topography. Streamflow responses are mainly affected by the rainfall characteristics; differences in streamflow and hydrochemistry between catchments with different portions of forest, meadows and wetlands, were relatively small. However, variations in the chemistry of baseflow along stream reaches within a catchment were considerable. Above all, these studies highlight the value of combining data on spatial patterns of groundwater levels and stream chemistry with long term data on streamflow to derive a more complete picture of the dominant runoff generation mechanisms.

“…In all studied watersheds, intermittent farm streams without a forest cover accounted for more stream length than perennial farm streams without a forest cover ( Table 2), suggesting that these intermittent streams are major recipients of nutrient, pesticide and sediment pollution. Although not considered in this study, it would be very useful to map ephemeral streams, road side ditches, swales and surface field drainage ditches in agricultural watersheds, as they are key hydrological features that should also be considered for riparian buffer establishment [93].

Abstract:In temperate agricultural watersheds, the rehabilitation of tree vegetation in degraded riparian zones can provide many ecosystem services. This study evaluated ecosystem service provision potential following the conversion of non-managed herbaceous buffers to hybrid poplar (Populus spp.) buffers in three watersheds (555-771 km 2 ) of southern Québec (Canada), with contrasting agricultural land uses. To extrapolate services at the watershed level, total stream length where hybrid poplars could be established was calculated using GIS data from hydrological and land cover maps. After nine years, a 100% replacement of herbaceous buffers by hybrid poplar buffers along farm streams could lead to the production of 5280-76,151 tons of whole tree (stems + branches) biomass, which could heat 0.5-6.5 ha of greenhouses for nine years, with the potential of displacing 2-29 million litres of fuel oil. Alternatively, the production of 3887-56,135 tons of stem biomass (fuelwood) could heat 55-794 new farmhouses or 40-577 old farmhouses for nine years. Producing fuelwood in buffers rather than in farm woodlots could create forest conservation opportunities on 300-4553 ha. Replacing all herbaceous buffers by poplar buffers could provide potential storage of 2984-42,132 t C, 29-442 t N and 3-56 t P in plant biomass, if woody biomass is not harvested. The greatest potential for services provision was in the Pike River watershed where agriculture is the dominant land use. A review of the potential services of poplar buffers is made, and guidelines for managing services and disservices are provided.
