“…Intensive cattle movements on fine-textured seasonally submerged soil can affect water storage and water movement into and within the soil. When the soil is wetter than optimum for wheel traffic, excessive trampling by cattle decreased total porosity, size and continuity of the pores (Servadio, Marsili, Pagliai, Pellegrini, & Vignozzi, 2001). …”

Information on hydraulic conductivity and macro-and micro-aggregate stability is needed for evaluating the ease with which soils slake and erode when in contact with water. In fine-textured soils, it will provide information on ponding of water and decrease in hydraulic gradient with wetting. This study was conducted to determine changes in hydraulic conductivity and macro-and micro-aggregate stability of a fine-textured submerged soil under intense cattle grazing for 15 years. Hydraulic conductivity of the cattle grazing soil ranged from very slow (0.46 cm hr -1 ) to slow (19.56 cm hr -1 ) in the top 0-25 cm depth, and attained near zero permeability (0.15 cm hr -1 ) before 75 cm depth. Permeability was rapid (21.1 to 30.06 cm hr -1 ) throughout the profile in the non-cattle grazing soil. Organic residues from cattle grazing activities raised the soil total organic carbon to as high as 72 g kg -1 in the top 0-25 cm depth. Wet trampling of organic residues from cattle excreta induced greater soil swelling and loss of soil strength resulting in low aggregated silt and clay (ASC) and clay flocculation index (CFI) within the 25-75 cm depth. Clay dispersion index (CDI) showed significant negative (P < 0.05) relationships with mean weight diameter (MWD) of water stable aggregates and saturated hydraulic conductivity (r = -0.631 and -0.596 respectively). Soil parameters controlling water storage and infiltration in such soils need to be increasingly studied to increase the area of land available for crop production and reduce soil erosion since such soils usually have high chemical fertility status.

“…O uso de máquinas agrícolas nas várias etapas do processo de produção em condições inadequadas de umidade (Dias Junior & Pierce, 1996;Novais & Smyth, 1999;Imhoff et al, 2001;Servadio et al, 2001;Silva et al, 2002;Chamen et al, 2003) tem sido o principal responsável por acarretar a degradação da estrutura do solo, diminuindo seu potencial produtivo. Esta degradação pode estar associada à compactação do solo (Ribeiro, 1999;Çarman, 2002;Chamen et al, 2003).…”

RESUMO O Estado de Minas Gerais é o maior produtor de café doBrasil, com mais de 50 % da produção total, sendo grande parte da área cultivada originalmente ocupada por vegetação de cerrado. Essa região é destaque na cafeicultura em razão da alta tecnologia empregada na mecanização, que submete o solo ao tráfego de máquinas, tornando preocupante a possibilidade de disseminação da compactação do solo. Objetivou-se com este estudo: (a) propor modelos de capacidade de suporte de carga de um Latossolo Amarelo distrófico típico (LAd) cultivado com cafeeiro em função da pressão de preconsolidação e da umidade, (b) determinar, com o uso destes modelos, em três profundidades e em duas épocas de amostragem, a influência das operações de manejo na estrutura do Latossolo Amarelo nas estações: seca e chuvosa. As amostragens foram realizadas em três camadas (0-3, 10-13 e 25-28 cm), sendo 30 amostras coletadas no local onde não houve tráfego e 10 amostras na linha de tráfego para cada equipamento, coletadas nos meses de agosto de 2002 e março de 2003 para quantificar seu efeito na estrutura

“…Servadio et al (2001) studied the effects of compaction caused by heavy farm machinery on saturated hydraulic conductivity. The number of times the machinery passed over the land was found to be a critical factor (Bakker and Davis, 1995), with Servadio et al (2001) finding that wheeled machinery reduced the saturated hydraulic conductivity from 18.5 mm h -1 to 3.3 mm h -1 with one pass and to 1.1 mm h -1 after 4 passes. A tracked vehicle reduced saturated conductivity less, with one pass resulting in a value of 11.2 mm h -1 and four passes 7.5 mm h -1 .…”

Most approaches to this problem aim to upscale from individual grid cells to whole catchments, something that restricts the complexity of possible process representation, produces models that may not be parsimonious with the data needed to calibrate them and, faced with data uncertainties, provides computational limitations on the extent to which model uncertainty can be fully explored. Rather than upscaling to problems of concern, this thesis seeks to downscale from locations of known flood risk, as a means of identifying where land use management changes might be beneficial and then uses numerical modelling to identify the kinds of management changes required in those downscaled locations. Thus, the aim of this thesis is to test an approach to understanding the impacts of rural land management upon flood risk based upon catchment-to-source downscaling.This thesis uses the case study of the River Eden catchment (2400 km 2 ) as a test (1) it was shown to have a significant impact on downstream flood risk; and (2) it had range of data and information needed for modelling land use changes.The second part of this thesis explored the land management scenarios that could be used to reduce flood risk at the catchment scale. The scenarios to be tested were determined through a stakeholder participation approach, whereby workshops were held to brainstorm and prioritise land management options, and then to identify specific locations within the Eamont sub-catchment where they could tested. There were two main types of land management scenarios chosen: (1) landscape-scale changes, including afforestation and compaction; and (2) corresponding to a 5.8% decrease in peak discharge. A key conclusion is that land management practices have been shown to have an effect on catchment scale flooding, even for extreme flood events. However, the effect of land management scenarios are both spatially and temporally dependent i.e. the same land management practice has different effects depending on where it is implemented, and when implemented in the same location has different effects on different flood events.
