This Study is about the wetlands in the GyunggiDo Mountains. It is written in the point of the hydrogeomorphology, geology, and soil. And it has accessed to ecological environment. Wetlands are divided into mountain wetlands and river wetlands by location, relief, processes, hydrology, and the type of inlet and outlet of water in wetlands. Mostly mountain wetlands are formed by the process of destruction of mountain slope. So they are to be located in the knickpoint. Therefore the underground surface is visible and underground water is rising or leaking. At this process, the environment forming wetlands are made by soil that was influenced by geology and composed by fine and very fine granules.

We investigated the habitat distribution and diversity of ground beetles (Coleoptera: Carabidae), a bioindicator for assessing environmental changes on Geumo Mountain, in survey plots at different altitudes on the southern and northern slopes of Geumo Mountain in South Korea. From April to September 2021, we collected 1,384 individuals, 41 species, and 15 families of Carabidae from the survey sites. The dominant species collected was Synuchus cycloderus (347 individuals), followed by Carabus jankowskii (193 individuals). The monthly distributions of species richness and abundance were as follows: 24 beetles of 9 species in April, 115 beetles of 28 species in May, 288 beetles of 32 species in June, peaking at 379 beetles of 32 species in July, 354 beetles of 23 species in August, and 224 beetles of 14 species in September. Additionally, we collected 305 beetles of 32 species at 400 m, 326 beetles of 31 species at 500 m, 359 beetles of 27 species at 600 m, 582 beetles of 16 species at 700 m, and 112 beetles of 7 species at 800 m near the summit. The habitat distribution by slope was 307 beetles (20 species of 8 families) on the southern slope and 1,077 beetles (34 species of 15 families) on the northern slope. For the 307 beetles of 20 species collected from the southern slope, the diversity, evenness, and dominance indices were 0.981, 0.754, and 0.156, respectively. For the 1,077 beetles of 34 species collected from the northern slope, the diversity evenness, and dominance indices were 1.187, 0.775, and 0.101, respectively.

This study tried to reveal distribution of incision rate and the factors from fluvial terrace deposits on the western and eastern slopes in the Middle Sobaek Mountain Range, using OSL age dating and topographical analysis. An average incision rate of 0.220 m/ka was estimated in the western slope streams, while the streams on the eastern slope showed a lower average incision rate of 0.121 m/ka. These results seem to indicate that the study area experienced an asymmetric uplift. Patterns of incision rate in the study area were different from those in the Northern Sobaek Mountain Range, probably suggesting that the Sobaek Mountain Range experienced spatially different uplift patterns. Among the factors, which were considered to influence on distribution of incision rate in the study area (e.g., altitude of sampling point, distance from divide, distance from axis, channel width, and bedrock type), distance from axis showed the strongest relationship with incision rate. Therefore, uplift is thought to be the most significant factor in distribution of incision rate in the Middle Sobaek Mountain Range.

In general, a damage that occurs due to landslide or slope failure in urban areas is larger than that in rural areas. In order to reduce the damage, a program is necessary to categorize slopes based on properties and to manage them systematically. Based on the above necessity, a slope management program which is applicable to slope management in an urban area has been developed at Hwangryung mountain in Busan as a target area. The program has a function of systematic slope information constructed by slope ID number of each slope or sub-region of a mountain, making a slope data sheet, analysis and grouping of slope stability, and establishment of a data base. It can also be utilized practically by end users due to the convenient input, edition, printing, management and operation of slope data. For practical utilization of the developed program, a research related to construction of the slope management system for a regional area is demanded to be performed continuously. The supply and utilization of a web based slope management system would contribute to damage reduction.

Numerical prediction of nocturnal thermal high in summer of the 1995 near Taegu city located in a basin has been carried out by a non-hydrostatic numerical model over complex terrain through one-way double nesting technique in the Z following coordinate system. Under the prevailing westerly winds, vertical turbulent fluxes of momentum and heat over mountains for daytime hours are quite strong with a large magnitude of more than $120W/\textrm{m}^2$, but a small one of $5W/\textrm{m}^2$ at the surface of the basin. Convective boundary layer (CBL) is developed with a thickness of about 600m over the ground in the lee side of Mt. Hyungje, and extends to the edge of inland at the interface of land sea in the east. Sensible heat flux near the surface of the top of the mountain is $50W/\textrm{m}^2$, but its flux in the basin is almost zero. Convergence of sensible heat flux occurs from the ground surface toward the atmosphere in the lower layer, causing the layer over the mountain to be warmed up, but no convergance of the flux over the basin results from the significant mixing of air within the CBL. As horizontal transport of sensible heat flux from the top of the mountain toward over the basin results in the continuous accumulation of heat with time, enhancing air temperature at the surface of the basin, especially Taegu city to be higher than $39.3^{\circ}C$. Since latent heat fluxes are $270W/\textrm{m}^2$ near the top of the mountain and $300W/\textrm{m}^2$ along the slope of the mountain and the basin, evaporation of water vapor from the surface of the basin is much higher than one from the mountain and then, horizontal transport of latent heat flux is from the basin toward the mountain, showing relative humidity of 65 to 75% over the mountain to be much greater than 50% to 55% in the basin. At night, sensible heat fluxes have negative values of $-120W/\textrm{m}^2$ along the slope near the top of the mountain and $-50W/\textrm{m}^2$ at the surface of the basin, which indicate gain of heat from the lower atmosphere. Nighttime radiative cooling produces a shallow nocturnal surface inversion layer with a thickness of about 100m, which is much lower than common surface inversion layer, and lifts extremely heated air masses for daytime hours, namely, a warm pool of $34^{\circ}C$ to be isolated over the ground surface in the basin. As heat transfer from the warm pool in the lower atmosphere toward the ground of the basin occurs, the air near the surface of the basin does not much cool down, resulting in the persistence of high temperature at night, called nocturnal thermal high or tropical night. High relative humidity of 75% is found at the surface of the basin under the moderate wind, while slightly low relative humidity of 60% is along the eastern slope of the high mountain, due to adiabatic heating by the srong downslope wind. Air temperature near the surface of the basin with high moisture in the evening does not get lower than that during the day and the high temperature produces nocturnal warming situation.
