Development Area

Majority of Padang City residents inhabitant the region along sea shore for residential, public facility and economic center together with all of supporting facilities. That region is seismic prone area, also potentially affected by tsunami hazard and flood.This circumstances pushed local authority of Padang City to develop urban residential area to the north, east and south side of this city (Koto Tangah, Kuranji, Pauh, Lubuk Kilangan and Bungus Teluk Kabung sub-district), which are used to be water infiltration area. The function`s shifting of this area cause the change of soil density. This condition potentially causethe alteration of rainfall infiltration in to the soil.This research was conducted at 15 locations in Dadok Tunggul Hitam area, Koto Tangah sub-district (9 locations in development area and 6 locations in original area condition). Double Ring Infiltrometer are used in this study to predict infiltration rate and Sandcone for measuring soil density.This study used Horton Model to analyze infiltration rate by quantify infiltration rate data(f), constant infiltration rate (fc) and initial infiltration rate (fo). Moreover, regression analysis were used to quantify infiltration rate in order to determine its effects to soil density parameter.The results show that for high density soil (valuegd = 1,00 gr/cm3 to 1,50 gr/cm3), final soil infiltration rate in average is 0,1 mm/minuteto 0,9 mm/minute. This condition can cause decreasingof rainfall`s runoff infiltration capacity. Meanwhile, for low density of soil (valuegd = 0,30 gr/cm3to 1,00 gr/cm3), the infiltration rate value relatively high with final infiltartion rate reached 0,22 mm/minute. This analysis demonstrated that soil density influence the infiltration rate, where 23,7 % of infiltration capacity in Padang City development area is influenced by soil density parameter (gd), and the rest is influenced by other parameters

In the years 2008–2012, the infiltration capacity was monitored in the different sites, viz. on the arable land and permanent grassland. In the permanent grassland site the soil was characterised as Leptic Cambisol, loamy sand with the depth of the top layer 0.20 m while on the arable land, it was classified as Eutric Cambisol, sandy loam with the maximum depth of the topsoil humus horizon 0. 40 m. Experimental variants with different doses of incorporated compost were as follows: Variant 1 –without compost incorporation, Variant 2 – compost incorporated in the dose of 80 t.ha−1, Variant 3 – compost incorporated in the dose of 150 t.ha−1. It was found out within the study period that the application of the higher compost doses showed a positive effect on infiltration rate in both localities. In Variant 3, the highest values of the water infiltration were recorded. It can be concluded that the highest dose of compost (150 t.ha−1) improved and accelerated both the infiltration and water holding capacity of soil for a longer period. With the exception of the year 2009, increased values of water infiltration were recorded on experimental plots with arable land than with permanent grassland. It was found also that after five years have not been marked differences between variants. It follows that the regular supply of organic matter is necessary, preferably after three years.

Weighing Lysimeter

Infiltration estimation is made by tests such as concentric cylinders, which are prone to errors, such as the lateral movement under the ring. Several possibilities have been developed over the last decades to compensate these errors, which are based on physical, electronic, and mathematical principles. In this research, two approaches are proposed to measure the water infiltration rate in a silty loam soil by means of the mass values of a lysimeter weighing under rainfall conditions and different moisture contents. Based on the fact that with the lysimeter it is possible to determine acting soil flows very precisely, then with the help of mass conservation and assuming a downward vertical movement, 12 rain events were analyzed. In addition, it was possible to monitor the behavior of soil moisture and to establish the content at field capacity from the values of the weighing lysimeter, from which both approach are based. The infiltration rate of these events showed a variable rate at the beginning of the rainfall until reaching a maximum, to descend to a stable or basic rate. This basic infiltration rate was 1.49 ± 0.36 mm/h, and this is because soils with fine textures have reported low infiltration capacity. Four empirical or semi-empirical models of infiltration were calibrated with the values obtained with our approaches, showing a better fit with the Horton’s model.

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.

Este trabalho teve como objetivo estudar o efeito da aplicação de diferentes lâminas de vinhaça na infiltração de água no solo e verificar a adequação dos modelos de Horton e Kostiakov-Lewis na estimativa da taxa de infiltração. Os tratamentos corresponderam à aplicação de cinco doses de vinhaça (0, 200, 250, 300 e 350 m3.ha-1). A aplicação de vinhaça propiciou uma redução da taxa de infiltração básica do respectivo solo em estudo, causando efeito negativo para essa característica, pois, eleva o risco de erosão do solo e majora a possibilidade do escoamento superficial. O modelo de Horton propiciou o melhor ajuste sobre os dados observados, e o modelo de Kostiakov-Lewis superestimou os valores da taxa de infiltração.   UNITERMOS: vinhaça, infiltração, solo.     DALRI, A.B.; CORTEZ, G.E.P.; RIUL, L.G.S.; ARAÚJO, J.A.C.; CRUZ, R.L. VINASSE APPLICATION INFLUENCE ON INFILTRATION CAPACITY OF SANDY LOAM SOIL     2 ABSTRACT   The objective of this study was to analyze effects in different depth in soil water infiltration and to verify the Horton and Kostiakov-Lewis models adequacy in infiltration rate estimate. The treatments were five doses of vinasse (0, 200, 250, 300 and 350 m³.ha¹). The vinasse application reduced the soil erosion risk increasing the possibility of runoff. The Horton model had the best adjustment on the observed data, and the Kostiakov-Lewis model overestimated the infiltration rate values.   KEYWORDS: vinasse, infiltration, soil.

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.

The main cause of flooding and erosion that creates critical land in various regions in Indonesia is surface runoff. The surface runoff will occur if rainfall exceeds the capacity of soil water absorption (infiltration capacity). The soil management of each land use could improve the infiltration capacity. The water movement both on the surface and in the soil determines the water infiltration. This study predicts surface runoff based on the infiltration rate of various land uses and rainfall in the Ciliwung Watershed. A series of studies were performed in the upstream and middle areas of the watershed. Observations of soil properties, water movement, and rainfall were carried out in various dry land uses. The results showed that the soil's physical properties mostly determine the constant infiltration rate, which affected the water movement in the ground. The initial water content, the degree of saturation of the initial moisture content, and the soil's physical properties determine the time of constant infiltration rate. The value of constant rate infiltration and the time of its achievement define the amount of surface runoff that occurs.

Abstract Based on the Darcy's law and water balanceprinciple,some infiltration models have been proposed,but most of these models are not suitable for simulating infiltration into layered soils during unsteady rainfall. In this paper, a simple modelfor simulating water infiltration into the two-layer soil slopesduring unsteadyrainfallwasproposed, combined with the limit equilibrium methodto analyze the stability of thetwo-layer soil slope.The water infiltration rate of slopes depends on rainfall intensity and the actual infiltration capacity of soils. The proposedmodelhas been successfully applied to three cases (steady rainfall and homogeneous slope, unsteady rainfall and homogeneous slope,unsteady rainfall and two-layer soil slope), and it can be also combined with probabilistic methods to calculate the failure probability of slopes.Compared with the Richards model, the combination of the proposed model and the random field method can quickly obtain the failure probability of the slope.
