“…Thus, converting forest type or controlling the canopy height and stem density of coniferous forest could be the tools for regulating streamflow. Converting temperate coniferous forests into broadleaved forests has also been shown to increase water yield because winter interception loss is larger for evergreen compared to broadleaf deciduous forest (Swank and Douglass, 1974). This management practice could be applied to the uniform precipitation monsoon regions such as northern Japan to increase water yield (Komatsu et al, 2008a).…”

Modern ecohydrologic science will be critical for providing the best information to policy makers and society to address water resource challenges in the 21st century. Implicitly, ecohydrology involves understanding both the functional interactions among vegetation, soils, and hydrologic processes at multiple scales and the linkages among upland, riparian, and aquatic components. In this paper, we review historical and contemporary ecohydrologic science, focusing on watershed structure and function and the threats to watershed structure and function. Climate change, land use change, and invasive species are among the most critical contemporary issues that affect water quantity and quality, and a mechanistic understanding of watershed ecosystem structure and function is required to understand their impacts on water quantity and quality. Economic and social values of ecosystem services such as water supply from forested watersheds must be quantified in future research, as land use decisions that impact ecohydrologic function are driven by the interplay among economic, social, political, and biological constraints. Future forest ecohydrological research should focus on: (1) understanding watershed responses to climate change and variability, (2) understanding watershed responses to losses of native species or additions of non-native species, (3) developing integrated models that capitalize on long-term data, (4) linking ecohydrologic processes across scales, and (5) managing forested watersheds to adapt to climate change. We stress that this new ecohydrology research must also be integrated with socio-economic disciplines. Published in 2011. This article is a US Government work and is in the public domain in the USA.

“…Thus, such losses tend to be greater for evergreen forests than for deciduous forests (Hibbert, 1967;Schulze, 1982) and may be expected to be larger for fast-growing forests with high rates of carbon storage than for slow-growing forests. Consequently, afforestation with fast-growing conifers on non-forest land commonly decreases the flow of water from catchments and can cause water shortages during droughts (Hibbert, 1967;Swank and Douglass, 1974). Vincent (1995), for example, found that establishing high-water-demanding species of pines to restore degraded Thai watersheds markedly reduced dry season streamflows relative to the original deciduous forests.…”

“…The initial tree density at the time of planting was 3000 trees/ha, but is now about 1000-1200 trees/ha. With the same rainfall, more streamflow discharges from natural old deciduous forests because of the smaller evapotranspiration that occurs compared with coniferous forests [30,31]. The main factor influencing the recession characteristics was the evapotranspiration derived by different forest cover.…”

Abstract:In South Korea, since small forest catchments are located upstream of most river basins, the baseflow from these catchments is important for a clean water supply to downstream areas. Baseflow recession analysis is widely recognized as a valuable tool for estimating the baseflow component of the stream hydrograph. However, few studies have applied this tool to small forest catchments. So, this study was conducted to assess the applicability of the recession analysis methods proposed in previous studies. The data used were long-term rainfall-runoff data from 1982 to 2011 in the Gwangneung coniferous (GC) and deciduous (GD) forest catchment in Gyeonggi-do, South Korea. For the applicability assessment, six recession constant estimation methods, which were used by previous studies, were selected. The recession constants of the GC and GD catchments were calculated, and applicability assessments were conducted by comparing the recession predictions and baseflow separations. As a result, the recession constants for GC and GD were 0.8480 and 0.9235, respectively. This clear difference may be due to the different forest cover in each area. The correlation regression line, AR(1) model, and the Vogel and Kroll method showed lower error rates and appropriate baseflow indexes compared with other methods.
