○ Analysis and prediction of the environmental effects of climate-induced sediment disasters in mountainous watersheds.
-Synthesis of monitoring results.
Biweekly routine monitoring, combined with intensive monitoring during summer monsoon periods, was conducted in small mountainous watersheds in the Haean Basin, Yanggu from May 2008 through April 2010. Compared to small differences in sediment export among various watersheds, large increases in suspended sediment concentrations were observed during intensive rainfall events and the relationships between rainfall characteristics and TSS concentrations can be used to predict climate effects on sediment export.
-Prediction of climate-induced secondary stream water contamination via suspended sediment and organic matter Surges in stream water sediment coincided with large increases in heavy metals inc1uding Pb and the relationships between TSS and Pb concentrations can be used to predict the secondary contamination caused by stream water siltation in response to more frequent occurrence of intense rainfall events.
-Prediction of climate change-induced risks to stream water contamination Methods based on in-situ turbidity measurements and the relationships between TSS and metal concentrations were proposed to predict stream water siltation and associated secondary contamination in mountainous streams.
2. Development and effectiveness analysis of environmentally sound techniques for the reduction of forest sediment-related disasters.
○ The results obtained from the studies are as follows. In the 1st year, vegetation surveys in two fired forests located in the eastem coastal area (Sockcho, Gangnung) found 26 species 14 families and 25 species 12 families in Sockcho and Gangnung, respectively. Pine tree was selected as a native tree species for the development of restoring forestation technology in the aspects of availability.
Mycorrhization rate in containerized pine seedlings were increased by the lapse of time and seedling growth rate. In the 2nd year, diversity of mycorrhizal fungi were surveyed in pine forests, and we found that Atheliaceae and Rhizopogon sp. were dominant in red pine(Pinus dens떠ora) forests, while Cenococcum geophilum was dominant species in black pine(Pinus thunbergii) forests. In addition, One hundred seventy isolates belongs to 40 species of mycorrhizal fungi were isolated from the fruiting bodies or pine roots. NaCl tolerance and enzyme activity of these ECM isolates were investigated, and inhibition of root pathogenic fungi in mycelial growth and sporulation by culture filtrates of ECM fungi was confirmed. In the 3rd year, we tried to develop long term storage of ECM fungal isolates. Skimmed milk was the most efficient cryoprotectant compared to DMSO and glycerol, and Cenococcum geophilum was the best in reviability as well as mycorrhization on pine seedlings when it was used after keeping the is이ates at deep freezer and room temperature. In the 4th year, we applied different inoculum types (spore suspension and mycelial pellets) to the pine seedlings, which was transplanted from seeding container to outdoor landslide and in t he room. Inoculation of ECM fungi caused the increase in mycorrhization rate and seeding growth at the statistically significant level comparaed to uninoculated treatment in growth room, and ECM fungi and/or mat treatment caused the same results in mycorrhization rate, but not in seedling growth at the significant level. The reason that the seedlings could not grow well may due to the low temperature from September to December when the experiment was carried out in outdoor landslide.
○ Slope stability by root reinforcement.
- Slope stability by tree species -the enhancement of soil shear strength-
In order to determine root strength properties for several tree species, we measured root tensile force and strength for Pinus koraiensis, Larix kaempferi, Pinus densiflora, Quercus mongolica and Alnus japonica. Results showed that tensile force increased as a power function of root diameter. Mean tensile strengths were 184.75kgf/cm2(Pinus koraiensis), 172.78kgf/cm2 (Larix kaempferi), 176.25kgf/cm2(Pinus densiflora), 235.07kgf/cm2(Alnus japonica) and 228.70kgf/cm2(Quercus mongolica), and tensile strength has been found to increase significantly with decreasing diameter in roots. Also, soil shear strength was enhanced by roots of these tree species; 0.l1kgf/cm2(Pinus koraiensis), 0.10kgf/cm2 (Larix kaempferi), 0.11kgf/cm2(Pinus densiflora), 0.14kgf/cm2(Alnus japonica), 0.14kgf/cm2(Quercus mongolica).
- Slope stability by shrub species -in-situ pulling resistance-
Mean in- situ pulling force in roots were the most resistant in Sa!ix koreensis(34.56kgf), followed by Crepidiastrum platyphyllum(27.2341kgf), Aralia elata(26.56kgf), Stephanandra incise(26.00kgf), Zanthoxylum schinifolium(22.35kgf), Weigela subsessilis(20.73kgf) and Lespedeza bicolor(18.78kgf). Artemisia princeps(10.39kgf) and Rubus crataegifolius(8.37kgf) were the least resistant for in-situ pulling force in roots.
- Slope stability by shrub species -the enhancement of soil shear strength-
In order to evaluate applicability of the designed in-situ direct shear apparatus, we carried out direct shear test for roots of Lespedeza bicolor. Rooted soil resulted in higher shear strength by 0.0152kgf/cm2(site #1), 0.0350kgf/cm2(site #2) and 0.1438 kgf/cm2(site #3) than in non-rooted soil.
○ Influences of in - channel obstruction on sediment transport and morphodynamics in steep mountaìnous stream.
Steep mountainous streams are often characterized by bedrock channel, which temporally causes sediment storage and scouring due to channel obstructions, such as bedrock projection and large rocks. In this study, the influence of bedrock projection and large rocks on long term channel bed changes with sediment transport was statistically examined in a steep mountainous stream. As a result, both of sediment deposit, scour and variation depth were increased with increasing in mean bedrock projection area and volume of large rocks rather than bedrock relief and the number of large rocks. Theses results suggest that mean bedrock projection area and the volume of boulders play an important role on sediment transport providing channel bed relief in a steep mountainous stream. Based on these results, we suggest a new structure to control sediment transport, considering stream continuum in a river network.
○ Differences in bed grain size distribution by type of erosion control dam and downstream changes in channel bed grain size in steep mountainous stream.
To examine 1) differences in bed grain size distribution by type of erosion control darn, and 2) downstrearn variation of channel bed grain size and inf1uence of lateral input such as tributary or landslide, we conducted field ineasurement of channel bed grain in four steep mountainous streams. At sedimentation site behind check dam in reach outlet, bed grain size was coarser and indicating well-sorted condition in buttress check dams controlling sediment transport than in concrete check dams trapping sediment. Channel bed grain size decreased exponentially downstream, but increased suddenly in tributary junction or landslide area, indicating influence of lateral input on channel bed composition of mainstream.
○ Rainfall Pattem Regulating Surface Erosion and Its Effect on Variation in Sediment Yield in Post-wildfire Area.
We found that, with decreasing wildfire regimes and increasing elapsed years, the rainfall type regulating surface erosion changed from daily rainfall to net-effective rainfall (considering rainfall continuity) and its intensity increased continuously. In general, wildfires can destroy the stabilized forest floors, and thus rainfall interception by vegetation and litter layer should be reduced. Wildfires can also decrease soil pores in forest floors, and thus infiltration rates of soil are reduced. These two processes lead to frequent occurrence of overland flows required to surface erosion, and sediment yields in post-wildfire areas should increase linearly with increasing rainfall events. With the decreasing severity wildfire regimes and the increasing elapsed years, these processes should be stabilized, and therefore their sediment yields 머so decreased. Our findings on variations in sediment yields caused by the wildfire regimes and the elapsed years suggest understanding of hydrogeomorphic and ecologic diversities in post-wildfire areas, and these should be carefully examined for both watershed management and disaster prevention.
○ Spatio-temporal Variations of In-stream Large Wood Dynamics and Subsequent Export in Mountain Streams.
In upstream channels with narrow bankfull widths and low stream discharges, a massive amount of LW, resulting from forest dynamics and hillslope processes, may persist for several decades on valley floor. These pieces, however, are eventually transported during infrequent debris flows from small tributaries, as well as peak hydrology in main-stem channels, and are extremely fragmented by frictions with boulders, and stream bank and bed during transport. Although infrequent, these events can be dominant processes in the export of significant amounts of LW from upstream channel networks. In downstream channels with wide bankfull widths and high stream discharges, LW is dominantly recruited by forest dynamics and bank erosion at locations where the channel is adjacent to riparian forests. These pieces are continuously transported downstream with LW pieces that are supplied from the upstream watershed by floods.
○ Longitudinal Pattern of Large Wood Distribution in Mountain Streams.
In this study, we found that the effect of the boulders vary with the channel width; that is, whereas the unit L W load in the segment with narrow channel width increased continuously with increasing boulder number, it in the segment with wide channel width did not depend on the boulder number. This should be because that, in two channels having different widths, the rates of channel widths reduced by boulders are different although boulder numbers are same. Our findings on LW load varying with physical factors (i. e., interaction of boulder number and channel width) along the stream corridor suggest understanding for longitudinal continuum of hydrogeomorphic and ecologic characteristics in stream environments, and these should be carefully applied into the erosion control works for systematic watershed management and subsequent disaster prevention.
○ Experimental study on the effect of h-type debris catcher on capturing logs and boulders.
In recent years, open-type erosion control dams with various type have been constructed to supply and control sediment downstream considering stream continuum, and to capturing logs and debris flows, whereas closed-type erosion control dams was mostly constructed in past years. To verify and exarnine the effect of h-type debris catcher on trapping logs and boulders, hydraulic model experiment was conducted considering a slit spacing of debris catcher. As a result, effectiveness of h-type debris catcher on trapping logs and debris flow was verified, indicating differences in capture rate by a slit spacing.
○ Field Application of Small Woody Check Dam -Characteristics of channel bed variation in 2010-
During the study period(June-September 2010), the study area received rainfall of less than 1210.7mm recorded in the same period of 2009, and no heavy rainfall events(≥100mm/day) was recorded. Channel bed fluctuation (O.07m3/m/m) and change in bed grain size(1.1cm) in the upper reach of check dam installation was relatively smaller than 0.13m3/m/m and 1.9cm, respectively, in lower reach with no check dams, indicating channel bed fixation by check dam series. Finally we found that the relationship between channel bed fluctuation and change of bed material size is uncertain in this year. Therefore, long-term monitoring is required to elucidate such relationship.
○ Qua1ity evaluation of wood used for erosion control dam.
-Among the wooden members for erosion control dam, non-deposited sapwoods were heavily deterioration.
-Although the wddoy erosion control dam was used for seven years, the wood members have been kept enough mechanical properties.
-Therefore, continuous investigation is need to find out more exact endurance period.
-Utilization proficiency of damaged pine by forest fire was obtained.
○ Improvement of weathering and preservation properties of small-diameter wood.
- Wood-tar treated specimens showed good preservation properties in water and soil deposited condition.
- Wood vinegar treated wood showed best preservation efficiency in outdoor exposure condition.
- New utilization as eco-íriendly material of by-product which is obtained during making charcoal was suggested.
○ Standard manual for site planning of steel sediment control structures.
Based on field application methods, the standard manual for design and site planning of steel sediment control structures was addressed considering the pattern of sediment transport from debris flow to bed load for systematic prevention works. We addressed standard manual for two cases: the case of log catcher in landslide and debris flow-dominated segment(open-type erosion control dam, partial open-type erosion control dam, closed-type erosion control dam+log catcher), the case of log catcher in bedload-dominated segment(Closed-type erosion control dam+log catcher, sediment reservoir(sand catching structure)+log catcher, or independent construction of log catcher).
3. Development of Forest fire Behavior Prediction and Regional group Countermeasurement Technique for the Climatic Change and Forest Maturity.
○ The forest fire fuel moisture forecasting model according to the day elapsed after rain was developed. The fuels were classified by tree species, soil depth and fuel diameter. And The forest fire occurrence prediction model was developed from Canadian fine fuel code.
Data bases on the characteristics of fire spread, evacuation and ignition about forest fire fuel were constructed. The forest fire danger rating and danger map were constructed according to combustion characteristics by tree species and tree age classes using G.I.S. software.
The result on predictions which were based on the analysis of the fine fuel moisture code variations during last 15 years and forecasted from the forest fire prediction model and G.C.Ms was that the forest fire season would be changed. In other words, whereas the fire season at present were spring and fall, the season at future would be winter, December, January and February.
The resu1ts on one-side combustion ratio analysis of young age and middle age forest were that the ratio were 97.3% on young age forest and 16.5% on middle age forest. The combustion ratio on young age forest were 80.8% higher than on middle age forest. The death ratio on the forest of coniferous trees were 1.7% higher than on the forest of broadleaf trees(44%, 42.3%). The proper tree densities for forest fire damage limitations was 900~1,200 per ha.
The detailed forest fire danger map on Samcheok was constructed using 16 theme maps by factor related to forest fire occurrences. And the regional standard operating procedure for forest fire attack which was consisted of acceptance stage, prelimin따y attack stage, after extinguish stage and etc was constructed.
4. Development of Forest Environmental Inforrnation and Simulation System (FEISS) for prediction of forest disaster and evaluation of alternative management practices.
○ A region-scale modeling approach on forest carbon and water processes was developed using the hydro-ecological modeling system (RHESSys).
○ RHESSys model was combined with a infinite slope stability model to assess dynamic vulnerability on forest landslide with respect to daily precipitation variation.
○ A forest landscape model (LANDIS II) was regionally parameterized with field observation data and then, applied to predict future changes of forest stand structure at a regional scale. Those modelling results were combined with forest fire probability model to predict future change of fire regime with climate change.
○ High resolution satellite data was utilized to identify disturbed regions from fores fire. Combined with FGIS data, the satellite data was also applied to assess landslide vulnerability in Gangwon- do province.
○ E. This study was analyze characteristics of spatial and environmental at landslide hazard, and the damaged area of landslide hazard area was extracted. and the change of biomass estimate at landslide hazard.
○ F. And landslide hazard map was consσucted using GIS and administrative, and landslide probability map was constructed and evaluated based on conditional probability theory.
