Changes in land use in the Air Dingin watershed (DAS) area in Padang City, Indonesia, lead to a decrease in rainwater infiltration volume to the ground. Some land use in the Latung sub-watershed decrease in infiltration capacity with an increase in surface runoff. This research aims to determine the effect of land-use changes on infiltration capacity and surface runoff. Purposive sampling method was used in this research. The infiltration capacity was measured directly in the field using a double-ring infiltrometer, and the data was processed using the Horton model. The obtained capacity was quantitatively classified using infiltration zoning. Meanwhile, the Hydrologic Engineering Center - Hydrology Modeling System with the Synthetic Unit Hydrograph- Soil Conservation Service -Curve Number method was used to analyze the runoff discharge. The results showed that from the 13 measurement points carried out, the infiltration capacity ranges from 0.082 - 0.70 cm/minute or an average of 0.398 cm/minute, while the rainwater volume is approximately 150,000 m3/hour/km2. Therefore, the soil infiltration capacity in the Latung sub-watershed is in zone VI-B or very low. This condition had an impact on changes in runoff discharge in this area, from 87.84 m3/second in 2010 to 112.8 m3/second in 2020 or a nail of 22.13%. Based on the results, it is concluded that changes in the land led to low soil infiltration capacity, thereby leading to an increase in surface runoff.

Abstract In the semiarid Southwestern USA, wildfires are commonly followed by runoff-generated debris flows because wildfires remove vegetation and ground cover, which reduces soil infiltration capacity and increases soil erodibility. At a study site in Southern California, we initially observed runoff-generated debris flows in the first year following fire. However, at the same site three years after the fire, the mass-wasting response to a long-duration rainstorm with high rainfall intensity peaks was shallow landsliding rather than runoff-generated debris flows. Moreover, the same storm caused landslides on unburned hillslopes as well as on slopes burned 5 years prior to the storm and areas burned by successive wildfires, 10 years and 3 years before the rainstorm. The landslide density was the highest on the hillslopes that had burned 3 years beforehand, and the hillslopes burned 5 years prior to the storm had low landslide densities, similar to unburned areas. We also found that reburning (i.e., two wildfires within the past 10 years) had little influence on landslide density. Our results indicate that landscape susceptibility to shallow landslides might return to that of unburned conditions after as little as 5 years of vegetation recovery. Moreover, most of the landslide activity was on steep, equatorial-facing slopes that receive higher solar radiation and had slower rates of vegetation regrowth, which further implicates vegetation as a controlling factor on post-fire landslide susceptibility. Finally, the total volume of sediment mobilized by the year 3 landslides was much smaller than the year 1 runoff-generated debris flows, and the landslides were orders of magnitude less mobile than the runoff-generated debris flows.

One of the hazards of the erosion is soil infiltration capacity is decreased in the place of occurrence of erosion and increasing the volume of surface flow. It will also lead to the occurrence of the superficiality of the river due to the deposition of materials of soil erosion. These hazards need alternative agrotechnology which could reduce the rate of soil erosion. This research is to know the hazard of soil erosion in the upper watershed of the Aie Limau Kambiang and find out the alternative agrotechnology for reducing the soil erosion. This research was conducted. Soil samples collected was taken in purposive random sampling based on a unit of land. The data were analyzed using the universal soil loss equation. The research results of the largest erosion threat come from the land use of traditional gardens and plant density is low. The highest erosion 151,012.00 ton/ha/year was founded on the plantation blended that have a steep slope over 35% LS value of 9.5. The better of agrotechnology with increasing plant density, that could reduce erosion to 503.40 ton/ha/year. This means that the hazard of soil erosion could be controlled with land management and selected of the better agrotechnology.

In order to study the storage-infiltration effect of rainfall for sunken greenbelt in urban road, its storage-infiltration capacity of rainfall runoff was analyzed based on the rainfall balance equation of urban road in the time interval, and then the computational formulae of storage-infiltration rate was derived. Influence factors on storage-infiltration rate, such as design recurrence interval of rainfall, soil infiltration coefficient, greenbelt rate, and depth of sunken greenbelt, etc. were computed and analyzed by using the derived computational formulae with the rainfall intensity of Changchun city. Results show that: on the same condition, storage-infiltration rate of rainfall for sunken greenbelt in urban road increases linearly with the increase of soil infiltration coefficient, greenbelt rate, and depth of sunken greenbelt, and decreases with the increase of design recurrence interval of rainfall. Sunken greenbelt with depth of 0.05 ~ 0.25m can storage-infiltrate all of the rainfall that falls on the urban road when the greenbelt rate of urban road ranges from 20% to 40%. Eco-design program of sunken greenbelt in urban road is reasonable and feasible, and its storage-infiltration effect of rainfall is remarkable.

Forest fires often occur in many islands of indonesia including in Kalimantan, Sumatra, Java, Sulawesi and other regions. These fires can lead to damage for ecosystems, flora and fauna, even ecosystem hydrology. One of the hydrological system that was disturbed is the interception and infiltration. Interception is the ability of trees to retain water rain then rereleased in steam. Infiltration is the process of water absorbing into the soil, infiltration capacity is the soil’s ability of absorbing water per unit of time. This research is to know the rest of the tree's ability to retain water, and knowing the infiltration of ex forest fire area on TAHURA R. Soerjo, Ledug blocks. This research was carried out on 17-23 January 2019 in ex forest fire area on TAHURA R. Soerjo, with an elevation of 1100-1200 masl. In the ex forest fire area there are 2 dominant trees species to do measurements of interception, there are Tutup (Mallotus paniculatus) and Klerek (Sapindus rarak DC). The results of the interception on Klerek tree is 10% and Tutup is 60%.  For the capacity of the infiltration is 27, 6 mm/hour.

Funneling Ratio

<p>Stemflow can form hotspots of precipitation in forests. The stemflow funneling ratio describes the degree of concentration compared to open land rainfall in reference to the tree basal area. But how strongly does stemflow actually concentrate at the point of precipitation input to the soil? This depends on the size of stemflow infiltration areas. Findings hereon vary widely, as they refer to different tree and rainfall characteristics. Furthermore, due to little representative data on stemflow and the separate evaluation of stemflow and throughfall, the importance of stemflow as a hotspot is still subject to controversy. Using an extensive and representative field data set, we want to investigate the effect of stemflow on soil infiltration and percolation. Measurements were conducted on a 1-ha mixed beech forest plot in central Germany with intermediate stemflow generation. In high-resolution statistical designs, stand precipitation (stemflow, n = 65, and throughfall, n = 350) were recorded during three summers, and soil undisturbed (n = 420) and disturbed (n = 100) samples were taken and analyzed for physical and chemical properties. We calculated the spatial distribution of infiltration from stand precipitation data, rain intensity and soil infiltration capacity. Soil properties near stems (< 1m) and farther away were compared to determine a stemflow impact. Results show that stemflow infiltration areas are very small. Stemflow funneling at infiltration exceeds the conventional funneling ratio. Therefore, infiltration depth (L m<sup>-2</sup>) within stemflow infiltration areas is multiples of throughfall, even at dripping points. Soil properties close to trees are significantly different from the bulk soil, suggesting an accelerated soil formation process and a more developed soil structure. Stemflow-induced high soil water fluxes can be identified as an important driver for this pattern. Thus, the hotspot character of stemflow is confirmed by our findings. Stemflow-induced hotspots persist during infiltration and percolation. What is more, they have a direct and significant impact on the soil environment. Soil hydraulic properties facilitate quick water fluxes near stems. Such, trees might establish water flux bypasses from the canopy to the deeper subsurface.</p>

Concerns over freshwater scarcity for agriculture, ecosystems, and human consumption are driving the construction of infiltration trenches in many mountain protected areas. This study examines the effectiveness of infiltration trenches in a subalpine forested catchment in central Mexico, where public and private organizations have been constructing trenches for ~60 years. We rely on empirical data to develop rainfall-runoff models for two scenarios: a baseline (no trenches) and a trenched scenario. Field measurements of infiltration capacities in forested and trenched soils (n = 56) and two years of meteorological data are integrated into a semi-distributed runoff model of 28 trenched sub-catchments. Sensitivity analysis and hydrographs are used to evaluate differences in total runoff and infiltration between the two scenarios. Multiple logistic regression is used to evaluate the effects of environmental and management variables on the likelihood of runoff response and trench overtopping. The findings show that soil infiltration capacity and rainfall intensity are primary drivers of runoff and trench overtopping. However, trenches provided only a 1.2% increase in total infiltration over the two-year period. This marginal benefit is discussed in relation to the potential adverse environmental impacts of trench construction. Overall, our study finds that as a means of runoff harvesting in these forested catchments, trenches provide negligible infiltration benefits. As a result, this study cautions against further construction of infiltration trenches in forested catchments without careful ex ante assessment of rainfall-runoff relationships. The results of this study have important implications for forest water management in Mexico and elsewhere, where similar earthworks are employed to enhance runoff harvesting and surface water infiltration.
